modelling results in the average level of

wholesale prices at 74€/MWh already in

2020 and 103€/MWh in 2030). The

attainment of these price levels is hard to

imagine in reality, given that currently that

level is around 34€ and more renewable

Similarly, the effectiveness of the revised

RES-E support schemes (as proposed in the

RED II IA) is not critically discussed. First,

the report needs to emphasize that they

would not be based on any type of feed-in

tariff but premiums on top of market

revenues and these premium will be

auctioned. Second, the report needs to

consider the fact that such auctions may not

necessarily be effective in reducing the

support to renewable energy sources. This

is particularly relevant in a situation where

the share of renewables in the electricity

generation mix is expected to grow

Annex II: Stakeholder consultations

Public consultations

In preparation of the present initiative, the Commission has conducted several public

consultations, in particular:

public consultation on generation adequacy, capacity mechanisms, and the

internal market in electricity, conducted in 2013;

consultation on the retail energy market, conducted in 2014;

public consultation on a new energy market design, conducted in 2015;

public consultation on risk preparedness in the area of security of electricity

supply, conducted in 2015.

These public consultation and their results are describe in more detail below.

Stakeholder opinions are also summarised in boxes for each main policy option in

section 5 and, if appropariate, elsewhere of the present impact assessment. Even more

detailed representations of stakeholder opinions are contained in Section 7 of each the

annexes assessing the options for detailed measures.

Public consultation on generation adequacy, capacity mechanisms, and the internal

market in electricity

Resource adequacy related issues were the subject of a public consultation

conducted

from 15 November 2012 to 7 February 2013 through the

"Consultation on generation

adequacy, capacity mechanisms, and the internal market in electricity".

It was open to

EU and Member States' authorities, energy market participants and their associations,

and any other relevant stakeholders, including SMEs and energy consumers, and citizens.

It aimed at obtaining stakeholder's views on ensuring resource adequacy and security of

electricity supply in the internal market.

As regards the quality and representativeness of the consultation, the consultation

received 148 individual responses from public bodies, industry (both energy producing

and consuming) and academia. Most responses (72%) came from industry. Responses

were of a high standard, not only engaging with the questions posed and the challenges

being addressed, but bringing valuable insights to the Commission's reflections of this

important topic. The consultation appears representative in comparison with similar

consultations.

The following paragraphs provide a summary of the responses available on the

Commission's website

. The responses and a summary thereof are also available on the

Commission's website

(i)

Government interventions.

Respondents to the consultation responses repeatedly

highlighted the policy uncertainty and national uncoordinated interventions of

various kinds, in particular support for renewables, as being critical elements in

discouraging investment. This was highlighted frequently by industry and also by

academics and think tanks. The related issue of fixing the flaws of ETS was also

raised repeatedly by industry. For example Energy UK states that

"national

measures often response to a lack of coherence in EU energy policy itself

–

particular there is a conflict between the market driven approach to liberalisation

and to EU ETS and the various sectoral targets in renewables, energy efficiency

etc."

The Netherlands (Ministry of Economic Affairs)

responded "the absence of

a credible carbon policy and a lack of proper market functioning cannot be

underestimated";

Market functioning.

In the context of a weak demand and economic crisis,

Europe's energy markets today area was deemed characterised by two

developments: the integration of large amounts of renewables and the

implementation of the EU target model. This was clearly reflected in the

responses to this consultation. Overall respondents' opinions were split as to

whether energy-only markets could deliver investments needed to ensure

generation adequacy and security of supply. However, there is near unanimous

support from respondents for the importance of the completion of the integration

of day-ahead, and close to real time markets as a an important contributor to

security of supply although, some respondents caution that this will not address

fundamental problems with whether energy-only markets can deliver resource

adequacy Similarly, there are strong calls facilitating demand side response and

the development of grids in line with the ten year network development plan.

Almost all responses to the consultation raised the impact of RES E on the

market. For example the UK response discusses the impact that more low

marginal cost pricing will have on the market, and the issue is discussed in detail

in the Clingendael paper submitted in response to the consultation. Industry in

particular raised the issue about the impact that RES E support schemes had on

the market. While many raise the issue of any out-of-market support creating

distortions, the position set out in the response of Eneco, a Dutch company is

worth quoting

"In general, support for specific energy sources does not

undermine investments to ensure generation adequacy, it just changes the merit

order. But details of support mechanisms can, specifically if a support mechanism

lowers the value of flexibility".

This consideration can be seen in the numbers of

respondents who cite priority dispatch or lack of balancing responsibility for RES

E producers as posing particular problems on the market, an issue which is

separate from the level of support for RES producers, as indeed recognised by

Germany who stat in their response

"Allerdigs ist ein Umstieg von der

Festvergutuetung unter der garantierten Abnahme des EE-Stroms auf ein System

der Marktintergration notwendig, in dem die Erneueuerbaren ihre Einspeisung

an dem Marktpreissignal orientieren…".

(iii)

Assessing security of supply.

There is widespread recognition of a need for

improved assessment of generation and security of supply in the internal market

given the impact of both RES E and market integration. Proposal have been made

suggesting a need for more scenario analysis based on different weather

conditions, different timespans for the assessment (long-term, short-term), more

detailed assessment of flexibility and more coordination between TSOs and more

sensitivity analysis. In this regard the existing ENTSO-E generation adequacy

assessment is not felt to meet future needs, without suggesting that ENTSO-E is

not carrying out its current role properly. There is particularly strong support for

more regional generation adequacy assessments combined with a common

methodology for undertaking such assessments. For example France in its

response states

"Il pourrait notamment être utile de renforcer la cohérence à

l’échelle régionale des différentes méthodes d’analyse et des scénarios produits

au niveau national, souvent interdépendants. Ces analyses régionales viendraient

ensuite alimenter un exercice réalisé à l’échelle de l’Union".

Support for binding

standards is less strong among respondents. Many of those who, in principle,

would welcome common standards point to the difficulties in establishing such

standards while MS retain responsibility for Security of Supply (and hence

determining standards). Others (such as the Oeko institute) consider that more

harmonised activities of Member states are essential in the internal market. There

was limited support for a revision of the Security of Supply directive, which was

perceived to fulfil its limited role. Again France states that

"Il apparaît préférable

de privilégier l’élaboration rapide de ces codes et achever ainsi la mise en oeuvre

des dispositions du 3

ème

paquet avant d’envisager des mesures nouvelles au

travers de la refonte de cette directive."

However some stated that since the

Directive was adopted before the Third Package, the situation after the Third

Package is different and therefore the level of cooperation prescribed by the

Directive does not correspond to today's situation. Summarising, there was

widespread support for a reassessment of how generation adequacy and security

of supply are assessed, and a recognition for the need for actions to be

coordinated. The question which stands out is what are the best tools to do this.

Here the electricity coordination group ('ECG') (explicitly mentioned by several

respondents) can play a critical role. The Commission will continue to examine

what are the best tools available to achieve the widely supported aim of improved

generation adequacy assessment.

Interventions to ensure security of supply.

As already noted opinion is divided on

whether energy only markets can deliver the investments which will be needed to

ensure generation adequacy and security of supply in the future. However, there

were even more varied opinions on the effectiveness of different capacity

remuneration mechanisms. Given this divergence of opinion therefore there is

only limited support for a European blueprint, many respondents pointing to

divergent local circumstances and the need to address specific problems as

(iv)

251

Annex II: Stakeholder consultations

kom (2016) 0863 - Ingen titel

militating against such an approach. Against this there was very strong support,

particularly among industry and academica, for EU wide criteria, governing

capacity mechanisms extending also to the high level criteria which proposed in

the consultation paper. Among Member States the UK specifically called for

criteria to be linked to State aid assessments, and notwithstanding caution about

overly detailed assessment at EU level its detailed comments on the individual

criteria in the consultation paper were broadly supportive. FR states

"Il est

toutefois utile et légitime que la Commission européenne suive de près l’impact

des choix des Etats membres sur le marché intérieur"

but also cautions that

"Il

semble prématuré à ce stade de définir des critères détaillés de compatibilité avec

le marché intérieur".

DE states that the Commission

"im Bedarfsfall eintreten,

der die Koordinierung zwischen den MS zu einer stärker gemeinsamen

…Gewährleistung der Versorgungssicherheit erleichtert.".

Consultation on the retail energy market

A public consultation dedicated to electricity retail markets and end-consumers

was

conducted from 22 January 2014 to 17 April 2014. It was open to all EU citizens and

organizations including public authorities, as well as relevant actors from outside the EU.

This public consultation aimed at obtaining stakeholder's views on the functioning of

retail energy markets.

As regards representativeness and quality, the Commission received 237 responses to the

consultation. About 20% of submissions came from energy suppliers, 14% from DSOs,

7% from consumer organisations, and 4% from NRAs. A significant number of

individual citizens also participated in the consultation.

The following paragraphs provide a summary of the responses, which are also available

on the Commission's website

(v)

Retail competition.

Respondents to this public consultation felt that market-based

customer prices are an important factor in helping residential customers and

SMEs better control their energy consumption and costs (129 out of 237

respondents considered that it was a very important factor while other 66

qualified it as important for the achievement of the said objective). Moreover, out

of 121 respondents who considered that the level of competition in retail energy

markets is too little, 45 recognised regulation of customer prices as one of the

underlying drivers.

81% of the respondents agreed that allowing other parties to have access to

consumption data in an appropriate and secure manner, subject to the consumer's

explicit agreement, is a key enabler for the development of new energy services

for consumers.

As regards whether it is sufficiently easy without facing disproportionate

permitting and grid connection procedures for a consumer to install and connect

renewable energy generation and micro-CHP pursuant to the provisions of the

RES and Energy performance in buildings Directives the views are split.

(vi)

Consumer issues.

222 out of 237 respondents to the retail market public

consultation believed that transparent contracts and bills were either important or

very important for helping residential consumers and SMEs to better control their

energy consumption and costs.

When asked to identify key factors influencing switching rates, 89 respondents

out of 237 stated that consumers were not aware of their switching rights, 110

stated that prices and tariffs were too difficult to compare due to a lack of tools

and/or due to contractual conditions, and 128 cited insufficient benefits from

switching.

178 out of 237 agreed that ensuring the availability of web-based price

comparison tools would increase consumers' interest in comparing offers and

switching to a different energy supplier. 40 were neutral and 4 disagreed.

Only 32 out of 237 respondents agreed with the statement: "There is no need to

encourage switching". 98 disagreed and 90 were neutral.

(vii)

DSOs and network tariffs.

The majority of the respondents consider that DSOs

should carry out tasks such as data management, balancing of the local grid,

including distributed generation and demand response, and connection of new

generation/capacity (e.g. solar panels). The majority of stakeholders thought these

activities should be carried out under good regulatory oversight, with sufficient

independence from supply activities, while a clear definition of the role of DSOs

(and TSOs), but also of the relationship with suppliers and consumers, is

required.

Regarding distribution network tariffs, 34% of the respondents consider that

European wide principles for setting distribution network tariffs are needed, while

another 34% is neutral and 26% disagree. Time-differentiated tariffs are

supported by ca 61% of the respondents, while the majority of stakeholders

consider that cost breakdown (78%) and methodology (84%) of distribution

network tariffs should be transparent.

The majority of stakeholders also consider that self-generators/auto-consumers

should contribute to the network costs even if they use the network in a limited

way. To this end, ca. 50% of the respondents consider that the further deployment

of self-generation with auto-consumption requires a common approach as far as

the contribution to network costs is concerned.

Regarding self- consumption, self- consumers should contribute to network costs

even if they use the network in a limited way and further deployment would

require a common approach. Moreover, however the responders think that to this

end a common approach with simplified related administrative procedures is

required. Granting of financial incentives by Member States to promote self-

generation and auto-consumption splits views evenly.

(viii)

Demand response.

Over 50% of the responders think that residential consumers

lack sufficient information to use energy efficiently and make use of advances in

innovation that have enabled a broad range of distributed generation and demand

response for industrial and commercial consumers. While the views are split in

respect to the ESCOs role to facilitate the favourable contractual arrangements

and other related services and as regards the access to respective choices of

energy efficiency services consumers have. Similarly, responders' views diverge

when assessing whether there should be done more to support the establishment

of ESCOs that are active in the field of energy efficiency. In particular, 44% of

the answers indicate that indeed there is more room to support ESCOs

establishment and 28% of the answers received point out that are satisfied with

the related service.

Moving on, the overwhelming majority industrial consumers are satisfied by their

access to demand response and balancing services while on the same question the

views coming from SMEs and commercial suppliers are split. Further, 24 of the

residential consumers have access to demand response and balancing services

while this percentage is 35% for the commercial sector and SMES and reached

the 66% for industrial customers. As to the entity of the demand response service

provider, over than 70% of the responders believe that this service should be

provided by the suppliers, though 50% thinks that aggregators are also fit to

provide the service while a minority would allocate this task to the DSOs.

Most responders view that they should be able to be participating in aggregation

programmes irrespective of their load size in primary balance markets. The best

way of making this happen is through aggregators and developing products taken

into account consumers flexibility characteristics and size. In addition,

responders' tend to agree that related demand response products should be hassle-

free, applicable to all consumers' profiles. People also disagree with the claim that

very specific data management tasks with regards to various distribution network

actors should be defined at European level.

Suppliers are perceived as having the most access to dynamic pricing and/or time

differentiated tariffs. They should first and aggregators, as a second choice, offer

demand response services and dynamic pricing to residential consumers, SMEs.

Unclear benefits, regulatory barriers and then unclear legal framework are

identified as the greatest barriers to limited dynamic pricing in a country. Some

respondents indicated that strengthening of infrastructure will allow greater retail

market competition

Responses agree that consumers should have a right to a smart meter installed at

their own request and at their expense also in regions without general rollout.

However, there is a slight tendency against having the choice of a smart meter

with functionalities of their own choice even if a different type is rolled out in

their area. In respect to smart appliances and energy management systems,

responders consider them as important to make the field of demand response

accessible to a broad range of consumers and that they can work as facilitators to

this end. The views also favour the display of consumption and consumption

patterns by the smart appliances and do not consider this as a detriment to the

consumers' comfort.

Public consultation on a new energy market design

A wide public consultation

on a new energy market design (COM(2015)340 was

conducted from 15 July 2015 to 9 October 2015. It was open to EU and Member States'

authorities, energy market participants and their associations, SMEs, energy consumers,

NGOs, other relevant stakeholders and citizens. This public consultation aimed at

obtaining stakeholder's views on the issues that may need to be addressed in a redesign of

the European electricity market.

As regards representativeness and quality, the Commission received 320 replies to the

consultation. About 50 % of submissions come from national or EU-wide industry

associations. 26% of answers stem from undertakings active in the energy sector

(suppliers, intermediaries, customers), 9% from network operators. 17 national

governments and several national regulatory authorities submitted also a reply. A

significant number of individual citizens and academic institutes participated in the

consultation.

The first assessment of the submissions confirmed broad support of a number of key

ideas of the planned market design initiative, while views on other issues vary. The

following paragraphs provide a summary of the responses, also available on the

Commission's website

(i)

Electricity market adaptations.

A large majority of stakeholders agreed that

scarcity pricing, i.e. price formation better reflecting actual demand and supply, is

an important element in the future market design. It is perceived, along with

current development of hedging products, as a way to enhance competitiveness.

While single answers point at risks of more volatile pricing and price peaks (e.g.

political acceptance, abuse of market power), others stress that those respective

risks can be avoided (e.g. by hedging against volatility). Regulated prices are

perceived as one of the most important obstacles to efficient scarcity pricing.

A large number of stakeholders agreed that scarcity pricing should not only relate

to time, but also to locational differences in scarcity (e.g. by meaningful price

zones or locational transmission pricing). While some stakeholders criticised the

current price zone practice for not reflecting actual scarcity and congestions

within bidding zones, leading to missing investment signals for generation, new

grid connections and to limitations of cross-border flows, others recalled the

complexity of prices zone changes and argued that large price zones would

increase liquidity.

Many submissions highlight the link between scarcity pricing and incentives for

investments/capacity remuneration mechanisms, as well as the crucial role of

scarcity pricing for kick-starting demand response at industrial and household

level.

Annex II: Stakeholder consultations

kom (2016) 0863 - Ingen titel

Most stakeholders agree with the need to speed up the development of integrated

short-term (balancing and intraday) markets. A significant number of

stakeholders argue that there is a need for legal measures, in addition to the

technical network codes under development, to speed up the development of

cross-border balancing markets, and provide for clear legal principles on non-

discriminatory participation in these markets.

Most stakeholders support the full integration of Renewable energy sources

(RES) into the market, e.g. through full balancing obligations for renewables,

phasing-out priority dispatch and removing subsidies during negative price

periods. Many stakeholders note that the regulatory framework should enable

RES to participate in the market, e.g. by adapting gate closure times and aligning

product specifications. A number of respondents also underline the need to

support the development of aggregators by removing obstacles for their activity to

allow full market participation of renewables.

As concerns phasing out of public support schemes for RES, stakeholders take

different positions. While some argue for phasing out support schemes as soon as

possible, others argue that they will remain an important tool until technologies

have fully matured. They point at existing fossil fuel subsidies and the need to

continue subsidizing RES and maintaining other market corrections as long as

subsidies for traditional fuels and nuclear are not removed. Certain stakeholders

underline that support could progressively take more and more the form of

investment aid (as opposed to operating aid). A large majority of stakeholders is

in favour of some form of coordination of regional support schemes. The need for

an ETS reform to allow full market integration of RES was mentioned very often.

Most stakeholders agree that diversified charges and levies are a source of market

distortions.

(ii)

Resource adequacy.

A majority of answering stakeholders is in favour an

"energy-only" market, possibly augmented with a strategic reserve. Many

generators and some governments disagree and are in favour of capacity

remuneration mechanisms. Many stakeholders share the view that properly

designed energy markets would make capacity mechanisms redundant.

There is almost a consensus amongst stakeholders on the need for a more aligned

method for resource adequacy assessment. A majority of answering stakeholders

supports the idea that any legitimate claim to introduce capacity remuneration

mechanisms should be based on a common methodology. When it comes to the

geographical scope of the harmonized assessment, a vast majority stakeholders

call for regional or EU-wide adequacy assessment, while only a minority favour a

national approach. There is also support for the idea to align adequacy standards

across Member States. Stakeholders clearly support a common EU framework for

cross-border participation in capacity mechanisms.

(iii)

Retail issues.

Many stakeholders identified a lack of dynamic pricing (more

flexible consumer prices, reflecting the actual supply and demand of electricity)

as one of the main obstacles to kick-starting demand side response, along with the

distortion of retail prices by taxes/levies and price regulation. Other factors

include market rules that discriminate consumers or aggregators who want to

offer demand response, network tariff structures that are not adapted to demand

response and the slow roll-out of smart metering. Some stakeholders underline

256

Annex II: Stakeholder consultations

kom (2016) 0863 - Ingen titel

that demand response should be purely market driven, where the potential is

greater for industrial customers than for residential customers. Many replies point

at specific regulatory barriers to demand response, primarily with regards to the

lack of a standardised and harmonised framework for demand response (e.g.

operation and settlement).

Regarding the role of DSOs, the respondents consider active system operation,

neutral market facilitation and data hub management as possible functions for

DSOs. Some stakeholders point at a potential conflict of interests for DSOs in

their new role in case they are also active in the supply business and emphasized

that the neutrality of DSOs should be ensured. A large number of the stakeholders

stressed the importance of data protection and privacy, and consumer's ownership

of data. Furthermore, a high number of respondents stressed the need of specific

rules regarding access to data. As concerns a European approach on distribution

tariffs, the views are mixed; the usefulness of some general principles is

acknowledged by many stakeholders, while others stress that the concrete design

should generally considered to be subject to national regulation.

(iv)

Regulatory framework/electricity market governance.

Stakeholders' opinions with

regard to strengthening ACER’s powers are divided. There is clear support for

increasing ACER's legal powers by many stakeholders (e.g. oversight of ENTSO-

E activities or decision powers for swifter alignment of NRA positions).

However, the option to keep the

status quo

is also visibly present, notably in the

submissions from Member States and national energy regulators. While some

stakeholders mentioned a need for making ACER'S decisions more independent

from national interests, others highlighted rather the need for appropriate financial

and human resources for ACER to fulfil its tasks.

Stakeholders' positions with regard to strengthening ENTSO-E remain divided.

Some stakeholders mention a possible conflict of interest in ENTSO-E’s

role –

being at the same time an association called to represent the public interest,

involved e.g. in network code drafting, and a lobby organisation with own

commercial interests

–

and ask for measures to address this conflict. Some

stakeholders have suggested in this context that the process for developing

network codes should be revisited in order to provide a greater a balance of in

interests. Some submissions advocate for including DSOs and stakeholders in the

network code drafting process.

A majority of stakeholders support governance and regulatory oversight of power

exchanges, particularly in relation to their role in market capacity. Other

stakeholders are skeptical whether additional rules are needed given the existing

rules in legislation on market coupling (CACM Guideline).

Stakeholders mention also that the role of DSOs and their governance should be

clarified in an update to the 3

Package.

(v)

Regionalisation of System Operation.

As concerns the proposal to foster regional

cooperation of TSOs, a clear majority of stakeholders is in favour of closer

cooperation

between TSOs. Stakeholders mentioned different functions which

could be better operated by TSOs in a regional set-up and called for less

fragmentation in some important of the work of TSOs. Around half of those who

want stronger TSO cooperation are also in favour of regional decision-making

responsibilities (e.g. for Regional Security Coordination Centres). Views were

split on whether national security of supply responsibility is an obstacle to cross-

border cooperation and whether regional responsibility would be an option.

Public consultation on risk preparedness in the area of security of electricity supply

A public consultation on risk preparedness in the area of security of electricity supply

was organized between July 15th and October 9th 2015. This public consultation aimed

at obtaining stakeholder's views in particular on how Member States should prepare

themselves and co-operate with others, with a view to identify and manage risks relating

to security of electricity supply.

The consulation resulted in 75 responses including public authorities (e.g. Ministries,

NRAs), international organizations (e.g. IEA), European bodies (ACER, ENTSO-E) and

most relevant stakeholders, including SMEs, industry and consumers associations,

companies and citizens. The following paragraphs provide a summary of the responses.

The responses themselves as well as a summary thereof are also available on the

Commission's website

(i)

Obligation to draw up risk preparedness plans.

A large majority of respondents

(75 %) is in favour of requiring Member States to draw up risk preparedness

plans, covering results of risk assessments, preventive measures as well as

measures to be taken in crisis situations.

There is also a large support for having common templates, which should ensure

that a common approach is followed throughout Europe. Many respondents stress

the need for common definitions, common assessment methods, and common

rules on how to ensure security of supply.

In fact, most respondents acknowledge that in an increasingly interconnected

electricity market, characterised by an increasing amount of variable supply,

security of supply should be considered a matter of common concern (countries

are increasingly dependent on one another and measures taken in one country can

have a profound effect on what happens in neighbouring states and in electricity

markets in general). They also acknowledge that the current legal framework

(Directive 89/2005) does not offer the right framework for addressing this inter-

dependence. Therefore, they take the view that risk preparedness plans based on

common templates can help ensure that each Member State takes the measures

needed to ensure security of supply whilst co-operating with and taking account

of the needs of others. Stakeholders, in particular from the industry, also stress

that risk preparedness plans should help ensure more transparency and reduce the

scope for measures that unnecessarily distort markets.

Whilst acknowledging the need for a common approach, a significant number of

stakeholders also state that there should be sufficient room for tailor-made,

258

Annex II: Stakeholder consultations

kom (2016) 0863 - Ingen titel

national responses to security of supply concerns, as there are substantial

differences between national electricity systems.

Respondents further agree that plans should be drawn up on a regular basis,

proposals range from 2 to 5 years. The degree of transparency of the plans should

depend on its content and may vary in function of it (given the fact that plans

contain possibly sensitive information). Finally, respondents also warn against

creating new administrative burdens and on this basis argue that any obligation to

make risk preparedness plans should take account of already existing assessment

and reporting obligations.

The minority of stakeholders taking the view that there should be no new legal

obligation to draw up risk preparedness plans argue that such plans are already in

place at the national level, that national electricity systems are profoundly

different from one another and that priority should be given to the process of

adopting network codes and guidelines.

(ii)

Content of risk preparedness plans / substantive requirements plans should

comply with.

Many stakeholders take the view that it is too early at this stage to

decide on the exact content of risk preparedness plans. They stress the need for

more analysis, as well as in-depth discussions on the issue, in particular within

the Electricity Coordination Group. In spite of this general caveat, consultation

results already contain many useful pointers about substantive requirements plans

should comply with:

Definition of risks. Various stakeholders stress the need to develop a common

definition of what security of supply means and the various risks that should

be covered. Risk preparedness plans should be comprehensive in nature,

covering generation adequacy and grid adequacy issues, as well as issues

related to more short-term security issues (such the risk of a sudden

unavailability of the grid or a power plant as a result of a terrorist attack);

Cybersecurity. Respondents generally acknowledge the importance of

preventing risks related to cyber-attacks but there is at this stage, no

agreement on the need for further specific EU measures;

Risk assessments and standards. Whilst the public consultation did not raise a

specific question on risk assessment methods and standards (since these

questions where covered by the market design consultation), various

stakeholders make the case for a common methodology for assessing risks, to

ensure a comparability of results, and a more common and transparent

approach to the standards that are used to assess risks and define an

acceptable level of reliability (this is also confirmed by replies to the market

design consultation). Various stakeholders also take the view that risk

preparedness plans should contain the results of various assessments made as

well as the indicators used to make the assessments;

Preventive measures. Stakeholders in favour of risk preparedness plans agree

that such plans should identify both demand-side and supply-side measures

taken to prevent security of supply issues, in particular situations of scarcity.

They also agree on the need to assess the impact of existing and future

interconnections and to take account of the import capacity when designing

259

Annex II: Stakeholder consultations

kom (2016) 0863 - Ingen titel

preventive measures. Many stakeholders point in this context to the need to

ensure that markets function in an optimal way, thus allowing for flexibility in

demand and a mix of solutions to ensure that a sufficient level of supply is

guaranteed whilst keeping distortive measures at bay. Finally, stakeholders

also stress that any assessment of import capacity should take account of the

expected situation in neighbouring Member States;

Dealing with emergency situations. A large majority of stakeholders agrees

that plans should identify actions (market and non-market based) to be taken

in emergency situations and rules on cooperation with other Member States.

A majority also believes that plans should include provisions on the

suspension of market activities, “protected customers” and cost compensation.

Additionally, some stakeholders suggest lists of specific content for the

emergency plans. As regards the development of new EU rules, many

stakeholders state that due account should be taken of the network code on

Emergency and Restoration, which is under preparation. Most say this draft

network code should be considered as the basis, whilst acknowledging a

possible need for additional common rules. A minority of stakeholders argues

that the network code on emergency and restoration should be considered

sufficient, leaving no need for additional EU-level rules, or consider that the

issues not covered by the network code should not be addressed at the EU

level;

Definition/clarification of roles and responsibilities and what operational

procedures to be followed (e.g., who to contact in times of crisis)

(iii)

Who should draw up risk preparedness plans, at what level, and with what kind of

'oversight'?

Who should be responsible for drawing up risk preparedness plans? Whilst

most stakeholders recall that national governments have the ultimate

responsibility for ensuring security of supply, many stakeholders consider that

TSOs should take a lead role in drawing up risk preparedness plans. Most

however consider that TSOs need to co-operate however with national

ministries and/or national regulatory authorities, with the latter assuming a

monitoring or supervisory role. There is a large support for a stronger DSO

involvement in the preparation of the plans as well, as well as a clarification

of the responsibilities of DSOs in crisis situations. Whilst most stakeholders

see the added value of designating one 'competent authority' per Member

States, there is no agreement on who that competent authority should be (and

some argue that this choice should be left with the Member States).

At what level should risk preparedness plans be drawn up? A large majority

of respondents take the view that plans should be made at national level;

however a large majority also stresses the need for more cross-border co-

260

Annex II: Stakeholder consultations

kom (2016) 0863 - Ingen titel

operation, at least in a regional context. A significant group of respondents

argues that plans should be made at the regional level (for instance, as a

complement to cross-border co-operation by TSOs in the frame of the

regional security coordination initiatives) or call for plans at national and

regional levels (or even 'multi-level' plans).

Those that argue in favour of

national plans highlight the fact that responsibilities (and liabilities) for

security of supply issues are national.

There is no agreement on how to

'define' regions for planning / co-operation purposes; most stakeholders

suggest that synchronous areas and/or existing (voluntary) systems of regional

co-operation should be used as a starting point. Finally, whilst only a minority

calls for European plans, many see the need for some degree of co-ordination

/ alignment of plans in a European context (in particular via the development

of common rules and peer reviews leading to best practice).

What oversight should there be? Most stakeholders are in favour of a system

of peer reviews, to be conducted either in a regional context, or in the frame

of the Electricity Coordination Group. The latter should in any event be

convened on a regular basis to serve as a forum for exchanging best practice.

Some stakeholders are also in favour of a stronger role for ACER/ENTSO-E,

in particular as regards more technical aspects of cross-border co-operation.

As regards the Commission, stakeholders mainly see a facilitating role, but

are often not in favour of a review system where the Commission takes

binding decisions.

Aspects of the present initiative were also part of the consultation on the preparation of a

new Renewable Energy Directive

for the period after 2020

which was conducted from

18 November 2015 to 10 February 2016. It was open to EU and Member States'

authorities, energy market participants and their associations, SMEs, energy consumers,

NGOs, other relevant stakeholders and Citizens. The objective of this consultation was to

consult stakeholders and citizens on the new renewable energy directive (RED II) for the

period 2020-2030, foreseen before the end of 2016. The bioenergy sustainability policy,

which will form part as well of the new renewable energy package, will be covered by a

separate public consultation. The stakeholder responses to this consultation are descibed

in more detail in the RED II impact assessment. A summary of the responses is however

also available on the Commission's website

Targeted consultations

A High Level Conference on electricity market design took place on 8 October 2015 in

Florence.

The rather cautious reaction to the idea of regional plans contrasts with the overwhelming support for

regional assessments of generation adequacy under the market design consultation.

A similar concern is reflected in the market design consultation results.

The consumer- and retail- related aspects of the market design initiative were also

discussed at the 8th Citizens' Energy Forum, which took place in London on 23 and 24

February 2016. The Commission established the London Forum to explore consumers'

perspective and role in a competitive, 'smart', energy-efficient and fair energy retail

market. It brings together representatives of consumer organisations, energy regulators,

energy ombudsmen, energy industries, and national energy ministries.

The Electricity Coordination Group provide a platform for strategic exchanges between

Member States, national regulators, ACER, ENTSOE and the Commission on electricity

policy. This group was used to discuss issues related to the present impact assessment on

16 November 2015 and 3 May 2016.

On demand response two specifc stakeholder workshops were organised by the

Commission: (i) Workshop on Status, Barriers and Incentives to Demand Response in

EU Member States, organised be the European Commission on 23 October 2015, and (ii)

of April 2016.

In these messages, the Presidency acknowledges

the challenges facing the electricity markets in Europe and emphasizes, inter alia:

the need to strengthen the functioning of the internal energy market; that correct

price signals in all markets and for all actors are essential; that an integrated

European electricity market requires well-functioning short-term markets and an

adequate level of cross-border cooperation with regard to balancing markets; that

security of supply would benefit from a more coordinated and efficient approach;

that the future electricity retail markets should ensure access to new market

players and facilitate introduction of innovative technologies, products and

services.

Generators

Reduction of priority dispatch and priority access facilitates grid operation and lowers

dispatch costs. Introduction of clear compensation rules on the other hand can increase

redispatch costs where such compensation is currently insufficient.

Where DSOs curtail generation to resolve local grid constraints, they are affected

identically to TSOs.

Implementation of balancing rules, notably settlement of parties in

imbalance.

They need to change the way non-frequency ancillary

services are contracted, procured and possibly

remunerated.

DSOs very likely would also be affected, because most

RES are connected at distribution level and the DSO's

role in managing their network would have to change

in order to allow RES assets to participate to the

provision of ancillary services.

Owners of generation assets (RES and not) would be

affected by changes in the rules of how non-frequency

ancillary services are procured. More transparent and

competitive procurement rules could enable market

entrance by new actors and technologies, such as

battery storage.

Most likely not affected.

No direct impact, as balancing is the role of TSOs; indirectly,

increased balancing responsibility of generators increases system

transparency also to the benefit of DSOs.

Suppliers

Generators currently subject to priority rules will be exposed to increased curtailment

risks and lower likelihood of dispatch (for high marginal cost generators; likelihood of

dispatch actually increases for low marginal cost generators) unless they continue to

benefit from the exemptions. Generators not subject to exemptions will be less likely to

be curtailed and more likely to be dispatched where they are the most efficient

generator available. All generators will benefit from increased transparency and legal

certainty on redispatch and curtailment compensation.

Balancing responsible parties, including suppliers, traders and

Measure

2.2. Removing distortions for liquid short-term markets

Member States authorities generally play a limited direct role in the

operation of intraday markets. They will, however be impacted if they

are responsible for implementing/enforcing requirements.

2.3. Improving the coordination of Transmission System Operation

Member States authorities will be impacted if they are responsible for

implementing/enforcing/monitoring the requirements. This topic is likely to have

a particularly political angle, as Member States may not be willing to entrust

ROCs with decision-making powers under the assumption that security of supply

is a national responsibility (although based on the TFEU, it constitutes a shared

responsibility between the EU and MS).

NRAs of each of the regions where a ROC is established would be required to

carry out the regional oversight of the concerned ROC. This would include

competences at least equivalent to those established for NRAs in the Third

Energy Package.

It may be necessary to entrust ACER with the EU-wide oversight of ROCs. It

would be necessary to set out a framework for the interaction between the

regional groupings of NRAs and ACER.

National TSOs would be complemented by ROCs performing functions of

regional relevance, whilst real time operation functions would be left solely in the

hands of national TSOs.

ROCs could potentially be entrusted with certain decision making responsibilities

for a limited number of operational functions, whilst TSOs would retain their

responsibility as regards all other functions for which they are currently

responsible at national level. It may be necessary to entrust additional tasks to

ENTSO-E related to the cooperation and coordination between ROCs.

Operators

(TSOs)

Generators

Aggregators

TSOs analyse system's state and propose the methodology

for sizing and procurement of balancing reserves in their

control areas.

Shifting responsibilities for sizing and procurement of

balancing reserves at regional level implies a need for

strong governance at regional level.

Existing physical constraints would still need to be taken

into account in the regional procurement platform.

Major impacts are expected on the current design of

system operation procedures and responsibilities. Cost

allocation and remuneration would have to be agreed,

requiring the development of a clear and robust framework

of responsibilities between national and regional TSOs.

Generators, as Balancing Service Providers, would have

additional opportunity to participate in the balancing

market even though significant operational impact might

increase due to the procurement frequency. Such

framework would, however, allow the participation of

renewable energy sources in the balancing market

potentially leading to a sharp decrease of balancing

reserve cost.

Smaller products and time units will give aggregators

more access to intraday markets.

Regional procurement of reserves would lead to regional

settlement of imbalances; therefore allowing for increase

competition of suppliers across borders.

In case an optimisation process for the allocation of

transmission capacity between energy and balancing

markets has to developed, day-ahead market coupling

algorithm currently operates by power exchanges might be

NRAs are responsible for regulatory oversight of intraday markets,

including as part of the implementation of the CACM Guideline,

where they are responsible for approving a number of methodology

developed by TSOs and power exchanges. They will, therefore, be

affected by changes in so far as it could alter the basis for their

regulatory decisions. However, the direct impact on NRAs is

anticipated to be relatively limited.

TSOs are heavily involved in the operation of intraday markets,

notably in determining the cross-border capacity made available to the

market, and in using the results for operation of the system. They are

therefore likely to be significantly impacted by any changes.

Generators will be affected by any changes in wholesale prices they

receive for their energy on the intraday market. More efficient price

signals, and more potential for trading, will open up the market to

smaller generators, particularly renewable.

Generators could benefit from a more secure power system and a more efficient

market leading to increased market opportunities.

Suppliers

Power

exchanges

Increased price fluctuations will give aggregators more opportunities

to operate, thereby helping to ensure that demand meets supply at any

point in time.

Suppliers will be affected insofar as they are the ones who buy power

on the wholesale market. Any changes in intraday clearing prices will

change how much they pay for their power, the extent to which will

depend on how much trading they do in the intraday market.

Power exchanges will be the most affected by any changes to intraday

arrangements, as they are the ones who operate the platforms on which

energy is traded in the intraday timeframe. They will therefore have to

adapt systems and process to meet new requirements.

Limited impact on aggregators.

Limited impact on suppliers.

3.1. Unlocking demand side response

Member States

Those 17 Member States that roll out smart meters

will not be affected by the new provisions on smart

meters, apart from the obligation to comply with the

recommended functionalities, which may need to

transpose into national legislation. Similarly for

those two Member States that opted for partial roll-

out and are not expected to face any other additional

burden from allowing additional consumers to

request smart meters.

However, those 9 Member States that currently do

not plan to install any smart meters will need to

establish legislation with technical and functional

requirements for the roll-out and face some

additional administrative impact by re-evaluating

their cost-benefit analyses.

What concerns market rules for demand response,

Member States are already obliged through the EED

to enable demand response. The new provisions will

rather provide additional guidance for Member

States on how to create the enabling framework

instead of imposing additional burden to them.

Additional administrative impact may be created for

the NRAs for enforcing actions regarding the

consumer entitlement to request a fully functional

smart meter. This includes assessing the costs to be

borne by the consumer, and overseeing the process

of deployment. At the same time, improved

consumer engagement thanks to smart metering,

would make it easier for NRAs to ensure proper

functioning of the national (retail) energy markets.

Already under the existing legislation NRAs are

obliged to encourage demand side resources to

participate alongside supply in markets. The new

provisions under the preferred option only further

specify which aspects have to be addressed by

NRAs but they do not create additional burden for

them.

As DSOs are regulated entities is expected that NRAs

will have the main role of ensuring the effective

application of measures. NRAs will be mostly

involved in the application of the measures and in

designing the necessary rules for the practical

implementation. As the measures under the preferred

option are closely linked to a suitable remuneration

methodology, NRAs will also probably have to

modify existing schemes. This will require the

availability of the necessary human, technical and

financial resources.

According to the Electricity Directive NRAs have the

main role in fixing or approving network tariffs or

their methodologies. The overall aim is to move

towards more sophisticated network tariff

methodologies. To this end, some NRAs might have

to modify the existing methodologies for distribution

tariffs. The introduction of smarter regulatory

frameworks will require the availability of the

necessary human, technical and financial resources.

Their role, powers and responsibilities will be

further clarified, especially as regards issues

which are relevant at regional/EU level. This

will affect the way NRAs have cooperated at

effects are dealt with in the Impact Assessment on

coming from smart metering. It supports them in

their work on monitoring and controlling the

network, improving its reliability and power quality,

and its overall effectiveness, particularly in the

presence of distributed generation. This ultimately

contributes to the increased distribution network

efficiency and increased revenue for the DSOs (e.g.

via reduced technical and commercial losses)

DSOs are not directly affected by the proposed

DSOs will be directly affected by the possible

measures under the preferred option as they will have

to have in place the necessary human and technical

resources in order to implement the envisaged

measures. Additional personnel or infrastructure

might be necessary. However, DSOs will use

flexibility solutions in order to increase efficiencies,

only where benefits will outweigh additional costs.

It is expected that the envisaged measures under the

preferred option will positively affect DSOs as they

aim to a more efficient utilisation of the distribution

system and the incentivisation of DSOs towards more

optimal development and operation of their grids.

More advanced tariff schemes may require the

availability and monitoring of detailed data (financial

and technical) and the achievement of specific

targets. Any additional administrative costs should be

offset by the expected benefits.

ENTSO-E's mandate will be mainly clarified,

whilst ensuring that its added value of

providing technical expertise is preserved.

Transparency of ENTSO-E will be further

improved.

Generators

Demand response is designed to reduce peak

demand and thereby effectively replace marginal

power plants and reduce electricity prices at the

wholesale market. As such generators are likely to

face reduced turnover from lower peak prices and

from operating reserve capacities.

Generators are not likely to be effected by an

accelerated smart meter roll out.

Generators will not be affected by the measures under

the preferred option.

Suppliers

Power exchanges

Smart meters can have a direct impact on suppliers,

as they enable consumers to easily switch.

Furthermore, there is one Member State where

suppliers are responsible for the roll-out. Moreover,

smart metering allows suppliers to offer dynamic

pricing contracts that reduce suppliers' risk of

changing wholesale prices.

The effect of demand response on suppliers can be

positive as suppliers will benefit from lower

wholesale prices. On the other hand demand

response will make it more difficult for suppliers to

calculate retail prices. Also as balancing responsible

parties they may face higher penalty payments for

imbalances incurred due to their customers changing

consumption patterns. Finally, new competition

from aggregators may reduce their income.

However, suppliers can also offer demand response

services to their customers and expand their range of

services and thereby turnover.

The overall financial impact of smart meters and of

more competition through demand response on

suppliers will hence depend on the ability of the

individual supplier to adapt to the new market with

innovative services and competitive pricing offers.

No impact expected

Suppliers will not be affected as the envisaged

measures will not affect their normal business.

The envisaged measures aim to the overall reduction

of network costs through the incentivisation of DSOs

to raise efficiencies, which will have an overall

positive impact to system users. The envisaged

measures also aim to a fair allocation of costs among

different system users. Therefore, to the extent to

which the envisaged measures will incite changes in

existing tariffs, generators or other system users

may be affected from any new tariffs which will

Aggregators (and

other

new

market entrants)

End consumers

Aggregators are likely to benefit from an accelerated

roll out of smart meters as this technology facilitates

market access for demand service providers and

aggregators. Equally all measures aimed at removing

market barriers and increasing competition in the

retail market will immediately facilitate market

access for aggregators and new energy service

providers and hence opens new business

opportunities for them.

End consumers will get the right to request smart

meters and have access to dynamic electricity

pricing contracts which clearly gives puts them in a

position to become active market participants.

Furthermore, provision of accurate and reliable data

flows due to smart metering would enable easier and

quicker switch between suppliers, access to choices,

smart home solutions and innovative automation

services, and can also lead to energy savings.

Consumers will equally benefit from more

competition, wider choice, and the possibility to

actively engage in price based and incentive based

demand response and hence from reduced energy

bills. But also those consumers who do not engage

themselves in demand response can profit from

lower wholesale prices as a result of demand

response if those price reductions are being passed

on to consumers.

Aggregators will be positively affected as DSOs will

request their services in order to use flexibility for

managing congestion in their networks.

Insofar as distribution tariffs incentivise grid users to

use the network more efficiently, aggregators will not

be called upon as much to help to manage network

congestion..

Aggregators and other new market entrants

will be able to participate more actively as a

result of the changes envisaged for the process

of development of Commission implementing

regulations in the form of network codes and

Use of flexibility from DSOs will result to lower

network costs. This reduction will be reflected in

distribution tariffs and the final electricity bill of the

consumer.

The envisaged measures aim to the overall reduction

of network costs through the incentivisation of DSOs

to raise efficiencies, which will have an overall

positive impact to system users. The measures also

aim to a fair allocation of costs among different

system users. Therefore, to the extent to which the

Member States (i.e. responsible ministries) would bear the main responsibility of preparing Risk Preparedness Plans and coordinating relevant parts with other

Member States from their region, including ex-ante agreements on assistance during (simultaneous) crisis and financial compensation.

Member States would designate a ministry or the NRA as 'competent authority' as responsible body for preparing the Risk Preparedness Plan and for cross-border

coordination in crisis.

As members of an empowered Electricity Coordination Group they would consult and coordinate Plans.

The above described responsibilities might involve an increased administrative impact. However, most of the tasks are already carried out in a purely national

context and there might also be benefits from exploiting synergies of improved cooperation. In addition, existing national reporting obligations would be reduced

(e.g. repealing the obligation of Article 4 of Electricity Directive "Monitoring security of supply").

NRAs could possibly fulfil certain tasks as part of the Risk Preparedness Plan of their Member State.

Furthermore they might be appointed as 'competent authority' by Member States. In this case, they would be responsible for preparing the Risk Preparedness Plan

and for cross-border coordination during crisis, possibly requiring additional resources.

ENTSO-E would be responsible for identification of crisis scenarios and risk assessment in a regional context. A common methodology for short-term assessments

(ENTSO-E Seasonal Outlooks and the week-ahead assessments of the RSCs) should be developed by ENTSO-E.

This might require additional resources within ENTSO-E and within the RSCs, in case that ENTSO-E delegates all or part of these tasks to them. However,

additional costs would be limited as some of these tasks are already carried out today. Giving these bodies a clear mandate, it would however significantly improve

cross-border coordination.

Generation companies and other market participants would not be directly affected by preparation of Risk Preparedness Plans. However, they would benefit from

clearer rules on crisis management and the prevention of unjustified market intervention.

7.1. Monitoring energy poverty

Member States

Option 1 leads to an improved framework to measure energy poverty.

Member States will have a better understanding of energy poverty as a

result of a clearer conceptual framework (through the common

understanding of energy poverty) and better information on the level of

energy poverty (measuring energy poverty). Ultimately, this will contribute

to better identification and targeted public policies to alleviate energy

poverty.

NRAs will need to monitor and report to the European Commission and

ACER the number of disconnections. According to ACER Market

Monitoring Report, only 16 Member States met this requirement.

Measure

7.2. Options for phasing out regulated prices

Those Member States still practicing some form of price regulation will

have to make the necessary legislative and market changes in order to

ensure a smooth and effective phase out.

7.3. Creating a level playing field for access to data

The competent ministries and authorities who will be

involved in the transposition of the relevant EU legislation

and will monitor the implementation and effectiveness of

the measures under the preferred option.

National regulatory

authorities (NRAs)

Transmission

System Operators

(TSOs)

The preferred option would not directly affect TSOs.

In most countries with price regulation, NRAs are the bodies

responsible for setting the level of regulated prices for a defined

regulatory period. In few cases NRAs are only giving their opinion on

regulated prices set by the government. Phasing-out regulated prices

would remove these responsibilities of the NRAs therefore reducing

administrative costs and resource needs. However new tasks for the

NRAs might be defined by Member States in the follow-up of the price

deregulation process such as monitoring the level of market prices with

the possibility to intervene ex post in the price setting in case of market

abuse. The costs of carrying out such new tasks are likely to be less

important than the costs of setting regulated prices, resulting overall in

reduces resource needs for the NRAs.

The preferred option would not directly affect TSOs.

The envisaged measures will partly affect the NRAs as most

probably will have a role in the implementation of the

measures at national level. Other authorities such as data

protection authorities may be involved in the

implementation of the envisaged measures at national level.

NRAs will have to monitor the data handling procedures as

part of the retail market functioning. The involvement of

NRAs is expected to be higher in Member States where

smart metering systems are deployed.

Distribution System

Operators (DSOs)

The preferred option would not directly affect DSOs.

TSOs might be affected in terms of costs in cases where

Member States will decide that they are responsible for the

operation of the data-hub. However, the envisaged measures

do not impose an obligation to Member States regarding the

data management model and the party responsible for acting

as a data-hub. The measures under the preferred option will

benefit TSOs and other operators as the will allow them,

under specific terms, to have access to aggregated

information which will be useful for network planning and

operation.

In the large majority of Member States DSOs will be

involved directly in the data handling process. DSOs will

have the same benefits as TSOs in terms of system

operation and planning. Under the preferred option DSOs

which are not fully unbundled (DSOs below the 100.000

threshold) will have to implement measures which link to

the non-discriminatory treatment of information. The

implementation of such measures will most probably create

costs which will vary depending on the national framework.

It is not expected however that these costs will create a high

burden, as they can implemented through automated IT

systems.

Generators

The preferred option would not directly affect generators.

Measure

7.2. Options for phasing out regulated prices

In countries where artificially low regulated end-user prices are backed

up by generation deliveries at non cost-reflective level agreed by long-

term contracts, deregulation of end user prices could trigger a

rethinking of such system by a renegotiation of long-term contracts

which would stimulate investment in efficient generation capacities

with positive effects on the competition on the generation market.

Alternative (non-regulated) suppliers would benefit from the

deregulation of prices by increased possibilities to compete on the price

and therefore to gain more market share. This is particularly true for

countries where regulated prices set at non cost-reflective levels

prevent alternative suppliers from contesting the regulated offer. For

the regulated suppliers (usually former incumbents) the removal of

price regulation would lead to increased operational costs related to the

implementation of the transition from the regulated offer to market

based offer for its customer base. Moreover, regulated suppliers are

likely to lose significant market shares if customers will switch to

competitive offers of alternative suppliers.

7.3. Creating a level playing field for access to data

Generators will not be affected under the preferred option.

Suppliers

Power exchanges

The preferred option would not directly affect suppliers.

However, should the improved monitoring of energy poverty lead to

increased action to tackle the problem by Member States, then the costs of

these measures may be borne by suppliers. Depending on each Member

States, these costs may then be recovered as network charges, passed on to

consumers or taken against energy providers overall benefits.

Preventative measures, such as debt management or providing additional

information on where to find support, represent an additional cost to

energy retailers in those Member States where these measures are not yet

in place. A moratorium of disconnection will reduce energy retailers'

revenue as energy will be supplied free of charge. However, such costs will

to some extent be mitigated by lower numbers of bad debtors in the long

run.

The preferred option would not directly affect power exchanges.

The availability of consumption data under non-

discriminatory terms and interoperability of data formats

will have positive effects on suppliers and other retailers.

The aim of the measures under the preferred option is to

bring down the administrative costs for the various retail

service providers including suppliers.

The preferred option would not directly affect power exchanges.

However, power exchanges could benefit from increased liquidity due

to better functioning competition on retail and wholesale markets

following price deregulation.

Removing price regulation would stimulate the development of energy

services which create market opportunities for aggregators.

Aggregators

The preferred option would not directly affect aggregators.

Consumers

Consumers in a situation of energy poverty or at risk of energy poverty will

be positively impacted by the preferred option. A clearer understanding

and measuring of energy poverty will have positive impacts on Member

States efforts to tackle energy poverty..

Phase-out of regulated prices for end customers would stimulate

competition on retail markets which translates for customers into more

choice and better offers in terms of price and service quality. Customers

would be able to better manage their own energy consumption by using

energy services and technologies such as demand response, self-

generation, and self-consumption. However, notably in countries where

prices are artificially regulated at low levels, price deregulation could

be followed by substantial increases in end user prices; to help

customers face such price increases, appropriate protection measures

for vulnerable customers should be in place prior to deregulation.

In the preferred option aggregators and other retail service

providers will have equal access to data as suppliers in a

transparent and non-discriminatory way. This will allow

aggregators to develop new services for consumers and will

facilitate their entrance in the market.

The envisaged measures under the preferred option aim to

support the development of a competitive retail market. It is

expected that the measures will bring developments which

will affect positively consumers through the availability of

wider choice of services, focusing on demand response and

energy efficiency.

Member States

The preferred option may need to be transposed into national

law, resulting in administrative impacts.

Some Member States (e.g. BE, IT) have eliminated exit fees

already, the latter reporting increased consumer trust as a

result. Others with a relatively high preponderance of exit fees

(NL, IE, SI) are likely to be more reserved, particularly in

light of the fact that they may have relatively competitive

markets already.

The preferred option would likely lead to additional

stakeholder engagement and enforcement actions, resulting in

increased administrative impacts to NRAs.

However, any clarification and simplification of EU legal

provisions may lead to greater ease of enforcement, and

commensurate savings.

In addition, improved consumer engagement would make it

easier for NRAs to ensure the proper functioning of national

(retail) energy markets they are charged with.

7.5. Comparison Tools

The preferred option will need to be transposed into national law, resulting in

administrative impacts.

However, some 13 Member States already have at least one independent CT run by a

government or government-funded body. As these are free of conflicts of interest, we

can assume they are likely to meet the accreditation criteria.

Suppliers

Any change in consumer switching behaviour resulting from

the preferred option would be reflected in switching

operations, and their associated administrative impacts.

However, as DSOs are regulated monopolies, these costs (or

savings, if switching decreases) will eventually be passed

through to end consumers.

Most suppliers are unlikely to welcome measures to further

restrict switching-related fees, as these limit their ability to

tailor tariffs to different consumers.

Some may also financially benefit from the increased

'stickiness' switching-related fees create amongst their

consumer base.

In addition, any change in consumer switching behaviour

resulting from the policy options would be reflected in

switching operations, and the associated administrative

impacts to suppliers.

Insofar as the measures lead to increased switching, this will result in increased

administrative costs to DSOs. However, these costs will be passed through to

consumers through network charges.

Not affected.

Comparison

tool

Not affected.

Industry associations (EURELECTRIC and Eurogas) have publicly supported

consumer access to neutral and reliable comparison tools. In particular, increased

reliability and impartiality in comparison tools may encourage new market entrants,

thereby improving the likelihood of a level playing field.

However, some suppliers are unlikely to welcome measures to certify comparison tools

as this may have an impact on how and where their offers are published, and their

ability to tailor tariffs to different consumers (in terms of cost, etc.).

Some may also lose out financially if they are no longer able to influence the ranking of

search results to promote certain offers; this applies both to energy suppliers and to CT

providers.

Insofar as the measures lead to increased switching, this will result in increased

administrative costs to suppliers.

More stringent requirements in terms of reliability and impartiality may increase their

costs, as may the need for accreditation. However, such costs may be offset by an

increase in sales due to improved trustworthiness of the comparison tool.

Most suppliers are unlikely to welcome EU legislation

addressing the content or format of energy bills, as this limit

their ability to tailor bills to different consumers.

Some may also benefit from the low awareness amongst

their consumer base of information that may be contained in

bills, such as switching information, consumer rights, and

consumption levels.

Description of analytical models used

In order to perform the quantitative analysis for the various Problem Areas, most notably

Problem Areas I and II, as well as for the evaluation of certain individual measures

described in the Annexes, a number of specialized energy modelling tools were used. The

selection of the modelling tool to be used in each case was made based on its ability to

answer the specific questions raised in each Problem Area.

METIS

For assessing the benefits of specific market design measures and their effect to power

system operation and market functioning, a new optimization software

was

used, currently being developed for the Commission

METIS was presented to the Member States' Energy Economists Group on April 5

2016. The Commission will be eventually the owner of the final tool. For transparency

reasons, all deliverables related to METIS, including all technical specifications

documents and studies, are intended to be published on the website of DG ENER

Global Description

METIS is an on-going project initiated by DG ENER for the development of an energy

modelling software, with the aim to further support DG ENER’s evidence-based

policy

making, especially in the areas of electricity and gas. The software is developed by a

consortium (Artelys, IAEW (RWTH Aachen University), ConGas, and Frontier

Economics) and a first version covering the power and gas system has already been

delivered to DG ENER.

It is an energy model covering with high granularity (geographical, time etc.) the whole

European energy system for electricity, gas and heat. In its final version it should be able

to simulate both system and markets operation for these energy carriers, on an hourly

level for a whole year and under uncertainty (capturing weather variations and other

stochastic events). METIS works

complementary

to long-term energy system models

(like PRIMES and POTEnCIA), as it focuses on simulating a specific year in greater

detail. For instance, it can provide hourly results on the impact of higher shares of

intermittent renewables or additional infrastructure built, as determined by long-term

energy system models.

Upon final delivery, METIS will be able to answer a large number of questions and

perform highly detailed analyses of the electricity, gas and heat sectors. A number of

282

Annex IV: Analytical models used in preparing the impact assessment.

kom (2016) 0863 - Ingen titel

topics will be possible to tackle with METIS for the whole EU and/or specific regions,

like:

The impacts of mass Renewable Energy Sources integration to the energy system

operation and markets functioning (for one or all sectors);

Cost-benefit analysis of infrastructure projects, as well as impacts on security of

supply;

Studying the potential synergies between the various energy carriers (electricity,

gas, heat).

On the other hand METIS is not designed to answer (at least in its first stage) questions

like:

Optimal investment planning (capacity expansion) for the EU generation or

transmission infrastructure;

Impacts of measures on network tariffs and retail markets;

Short-term system security problems for the electricity and gas system (requiring

a precise estimation of the state of the network and potential stability issues);

Flow-based market coupling and measures on the redesign of bidding areas;

Any type of projection for the energy system.

Description of the Power Markets and System Models

The software replicates in detail market participant's decision processes, as well as the

operation of the power system. For each day of the studied year, all market time frames

are modelled in detail: day-ahead, intraday, balancing. Moreover METIS also simulates

the sizing and procurement of balancing reserves, as well as imbalances.

Uncertainties regarding demand and RES E power generation are captured thanks to

weather scenarios taking the form of hourly time series of wind, irradiance and

temperature, which influence demand (through a thermal gradient), as well as PV and

wind generation. The historical spatial and temporal correlation between temperature,

wind and irradiance are preserved.

Calibrated Scenarios

–

METIS has already been calibrated to a number of scenarios of

ENTSO-E's Ten-Year Network Development Plan ('TYNDP') and PRIMES. METIS

versions of PRIMES scenarios include refinements on the time resolution (hourly) and

unit representation (explicit modelling of reserve supply at cluster and Member State

level). Data provided by the PRIMES scenarios include: demand at Member State-level,

primary energy costs, CO

costs, installed capacities at Member State-level and

interconnection capacities.

Geographical scope

–

In addition to EU Member States, METIS scenarios incorporate

ENTSO-E countries outside of the EU (Switzerland, Bosnia, Serbia, Macedonia,

Montenegro and Norway) to model the impact of power imports and exports to the EU

power markets and system.

Market models

–METIS market module replicates the market participants’ decision

process. For each day of the studied year, the generation plan (including both energy

generation and balancing reserve supply) is first optimized based on day-ahead demand

and RES E generation forecasts. Market coupling is modeled via NTC constraints for

interconnectors. Then, the generation plan is updated during the day, taking into account

283

Annex IV: Analytical models used in preparing the impact assessment.

kom (2016) 0863 - Ingen titel

updated forecasts and asset technical constraints. Finally, imbalances are drawn to

simulate balancing energy procurement.

Source: METIS

Reserve product definition

–

METIS simulates FCR, aFRR and mFRR reserves. The

product characteristics for each reserve (activation time, separation between upward and

downward offers, list of assets able to participate, etc.) are inputs to the model.

Reserve dimensioning

–

The amount of reserves (FCR, aFRR, mFRR) that has to be

secured by TSOs can be either defined by METIS users or be computed by METIS

stochasticity module. The stochasticity module can assess the required level of reserves

that would ensure enough balancing resources are available under a given probability.

Hence, METIS stochasticity module can take into account the statistical cancellation of

imbalances between Member States and the potential benefits of regional cooperation for

reserve dimensioning.

Balancing reserve procurement

–

Different market design options can also be compared

by the geographical area in which TSOs may procure the balancing reserves they require.

METIS has been designed so as to be able to constrain the list of power plants being able

to participate to the procurement of reserves according to their location. The different

options will be translated in different geographical areas in which reserves have to be

procured (national or regional level). Moreover, METIS users can choose whether

demand response and renewable energy are allowed to provide balancing services.

Balancing energy procurement

–

The procurement of balancing energy is optimized

following the same principles as described previously. In particular, METIS can be

configured to ban given types of assets, to select balancing energy products at national

level, to share unused balancing products with other Member States, or to optimize

balancing merit order at a regional level.

Imbalances

–

Imbalances are the result of events that could not have been predicted

before gate closure. METIS includes a stochasticity module which simulates power plant

outages, demand and RES E generation forecast errors from day-ahead to one hour

ahead. This module uses a detailed database of historical weather forecast errors (for 10

years at hourly and sub-national granularity), provided by the European Centre for

Medium-Range Weather Forecasts ('ECMWF'), to capture the correlation between

Member State forecast errors and consequently to assess the possible benefits of

imbalance netting. The stochasticity module will be further extended in the coming year

to include generation of random errors picked from various probability distributions

either set by the user or based on historical data.

PRIMES suite of models

In order to assess the impacts of the various market design options on generator profits

and investments, as well as the impact of capacity remuneration mechanisms and their

different designs, a suite of models built by NTUA were used, with PRIMES model

being at its core.

PRIMES

is a partial-equilibirum model of the energy system. It has been used

extensively by the European Commission for settting the EU 2020 targets, the Low

Carbon Economy and the Energy 2050 Roadmaps, as well as the 2030 policy framework

for climate and energy.

http://ec.europa.eu/clima/policies/strategies/analysis/models/docs/primes_model_2013-2014_en.pdf.

285

Annex IV: Analytical models used in preparing the impact assessment.

kom (2016) 0863 - Ingen titel

PRIMES is a private model which has been developed and is maintained by

E3MLab/ICCS of National Technical University of Athens

in the context of a series of

research programmes co-financed by the European Commission. The model has been

peer reviewed successfully, most recently in 2011

The PRIMES model is suitable for analysing the impacts of different sets of climate,

energy and transport policies on the energy system as a whole, notably on the fuel mix,

CO2 emissions, investment needs and energy purchases as well as overall system costs.

It is also suitable for analysing the interaction of policies on combating climate change,

promotion of energy efficiency and renewable energies. Through the formalised linkages

with GAINS non-CO

emission results and cost curves, it also covers total GHG

emissions and total non-ETS sector emissions. It provides details on the Member State

level, showing differential impacts across Member States.

Decision making behaviour is forward looking and grounded in micro-economic theory.

The model also represents in explicit way energy demand, supply and emission

abatement technologies, and includes technology vintages. The core model is

complemented by a set of sub-modules modelling specific sectors. The model proceeds

in five year steps and has been calibrated to Eurostat data for the years 2000 to 2010.

For the electricity sector, the PRIMES model quantifies projection of capacity expansion

and power plant operation in detail by Member State distinguishing power plant types

according to the technology type (more than 100 different technologies). The plants are

further categorised in utility plants (plants with as main purpose to generate electricity for

commercial supply) and in industrial plants (plants with as main purpose to cogenerate

electricity and steam or heat, or for supporting industrial processes). The model finds

optimal power flows, unit commitment and capacity expansion as a result of an inter-

temporal non-linear optimisation; non-linear cost supply functions are assumed for all

resources used by power plants for operation and investment, including for fuel prices

(relating fuel prices non-linearly with available supply volumes) and for plant

development sites (relating site-specific costs non-linearly with potential sites by

Member State); the non-linear cost-potential relationships are relevant for RES E power

possibilities but also for nuclear and CCS.

The simulation of plant dispatching considers typical load profile days and system

reliability constraints such as ramping and capacity reserve requirements. Flow-based

optimisation across interconnections is simulated by considering a system with a single

bus by country and with linearized DC interconnections. Capacity expansion decisions

depend on inter-temporal system-wide economics assuming no uncertainties and perfect

foresight.

The optimisation of system expansion and operation and the balancing of demand and

supply are performed simultaneously across the EU internal market assuming flow-based

allocation of interconnecting capacities. The outcome of the optimisation is influenced by

policy interventions and constraints, such as the carbon prices (which vary endogenously

to meet the ETS allowances cap), the RES E feed-in tariffs and other RES E obligations,

the constraints imposed by legislation such as the large combustion plant directive,

constraints on the application of CCS technologies, policies in regard to nuclear phase-

out, etc.

The optimality simulated by the model can be characterised either by a market regime of

perfect competition with recovery of stranded costs allowed by regulation or as the

outcome of a situation of perfectly regulated vertically integrated generation and energy

supplying monopoly. This is equivalent of operating in a perfect way a mandatory

wholesale market with marginal cost bidding just to obtain optimal unit commitment and

a perfect bilateral market of contracts for differences for power supply through which

generators recover the capital costs.

According to the model-based simulations, the capital costs of all plants, taken all

together as if they belonged to a portfolio of a single generating and supplying company,

are exactly recovered from revenues based on tariffs applied to the various customer

types. This result does not guarantee that the optimal capacity expansion fleet suggested

by the model-based projections cam be delivered in the context of more realistic market

conditions with fragmentation and imperfections.

PRIMES was not directly used in this impact assessment, although the PRIMES

EUCO27 setup was the basis for all analyses, with all inputs exogenous to the power

sector, as well as generation capacities, coming from it. The main obstacle in using

PRIMES for this impact assessment was that it assumes a perfectly competitive and well-

functioning market.

For this scope two sub-modules closely linked to PRIMES were used instead:

PRIMES/IEM is a day-ahead and unit commitment simulator, modelling the

operation of the European electricity markets and system for a given year, being

able to capture different market designs and market participant behaviours.

PRIMES/OM is a variant of PRIMES, modifying the use of PRIMES in order to

simulate investments under various competition regimes and with the possibility

to capture the effect of CMs.

The two models are described below in more detail

PRIMES / IEM

PRIMES/IEM aims at simulating in detail the sequence of power markets - Day-ahead,

Intraday, Balancing and Reserve Procurement - in the EU for one year, covering all EU

28 Member States and their interconnections (also linked to non-EU European countries).

PRIMES/IEM is calibrated to PRIMES projections, taking as exogenous inputs:

The detailed methodology followed, along with results, is described in a relevant report prepared for

the scope of the impact assessment: "Methodology

and results of modelling the EU electricity market

Load (hourly);

Power plant capacities (as projected) and their technical-economic characteristics,

including old plants as available in projection period, new investments and

refurbishments as projected by PRIMES;

Fuel prices, ETS carbon prices, taxes, etc.;

Resource availability for intermittent renewables;

Interconnection capacities;

Heat or Steam serving obligations of CHP plants having production of heat or

steam as main purpose;

Restrictions derived from policies, e.g. operation restrictions on old plants,

renewable production obligations, if applicable, support schemes of renewables,

biomass and CHP.

PRIMES/IEM disaggregates the interconnection network, considering more than one

node per country, with connecting grids within the countries, in order to represent intra-

country grid congestions. The assumptions about the grid within each country and across

the countries change over time, reflecting an exogenously assumed grid investment plan.

It also uses a more disaggregated hourly resolution than PRIMES, in representing load

and availability of intermittent RES E resources, as well as more disaggregated technical

and economic data for each plant than PRIMES, to represent cyclical operation of plants,

possible shut-downs and start-ups. Finally, PRIMES-IEM uses detailed data on ancillary

services (reserves) and the capability of plants to offer balancing services.

The day-ahead algorithm (GAMS program, written by E3MLab) is based on the

EUPHEMIA

algorithm. The code runs for all countries and the user can select countries

to simulate market coupling. The power plant capacities, demand (hourly for the days

selected) and other information (e.g. grid) come from PRIMES database and projections.

The linkage of data to PRIMES is fully automatic. The user can define rules for bidding

by the plants, and the power plants (production hourly) which are 'must-take' and/or

nominations. Available transfer capacities between countries can also be specified in the

interface.

The unit commitment algorithm (GAMS program written by E3MLAB and solved as a

mixed integer linear program) is a fully detailed plant operation scheduling algorithm. It

includes the technical features of the power plants (technical minimum, minimum up-

time, minimum down-time, ramp-up rates, ramp-down rates, time to synchronize, time to

shut down and capability of providing ancillary reserve services to the system), the

technical features of the interconnectors (applying DC linear power flows) and the

reserve requirements of the system (primary, secondary, spinning tertiary, non-spinning

tertiary and optionally ramping-flexibility reserves). The program runs simultaneously

for the selected countries, which are assumed to operate under a coordinated-

synchronized unit commitment. The program runs on an hourly basis and simultaneously

The code is fully consistent with the unit commitment codes ran by TSOs in Europe and

in the USA (compatible with the recommended code by FERC in the USA).

The day-ahead market Simulator (DAM_Simul) runs all EU countries simultaneously,

solving market clearing by node (one node per country) and calculating interconnection

flows restricted by DC power flows and by Available Transfer Capacities (defined by

pair of countries).

Market participant bidding

is based on marginal costs plus mark-up reflecting scarcity.

Must take CHP, RES and nominated capacities are included in DAM simulation as fixed

(unchanged) hourly amounts. Similarly the reservation of cross-border capacity for

nominations is fixed. In some policy-options these assumptions are relaxed. The

wholesale prices of DAM are calculated from the relaxed problem, after having run the

mixed integer problem. The DAM-Simulator runs pan-European and includes

interconnection flows subject to limitations of power flow and NTC/ATC restrictions as

applicable and if applicable in each policy option.

The unit commitment simulator (UC_Simul) includes exogenously defined reserve

requirements, the outcomes of the event generator, the operation schedule of all units, the

bids in DAM and penalty factors for slack variables (re-dispatching). Operation of small-

RES E and must-take CHP is fixed. The unit commitment simulator runs pan-European

limited by power flows and NTC values.The purpose of this run is to determine the

deviations from DAM schedule, to be used in the intraday and balancing simulator.

The Intraday and Balancing Simulator (IDB_Simul) runs the above intraday and

balancing market (once for 24-hours all together) and determines a price for deviations,

the financial settlement of deviations and a revised schedule for operation of units and

interconnectors.

In IDB_Simul, eligible resources can bid for supplying power to meet the deviations. The

bids can differ for upward and for downward changes of power supplied by the eligible

resources. Eligibility is defined specifically for each policy option. Capacity from

interconnectors may be eligible but only if remaining capacities (beyond the schedule of

the unit commitment) allow for this.

Bidding functions are defined by plant in DAM on the basis of the marginal fuel cost of the plant,

increased by a mark-up defined hourly as depending on scarcity. The modelling of the bidding

behavior of generators, similar in PRIMES/IEM and PRIMES/OM, is discussed in detail in the

PRIMES/OM Section.

In the Reserve and ancillary services procurement Simulator (RAS-Simul) demand for

reserves is defined exogenously (equal to demand used in the UC_Simul). The outcome

of RAS-Simul is the remuneration of the resources for providing reserves and a possible

(small) modification of the schedule of units and interconnection flows.

For each policy option the demand for reserves is differentiated. Eligible resources can

bid for supplying power to meet the demand for the different types of frequency reserves.

Also, a subset of plants are eligible in each market for reserve. When the bids are

endogenous and market-based, the prices include scarcity markups, with scarcity

referring to the market for reserves. Eligibility of resources is defined differently for each

policy option. Resources available cross-border can participate (differently constrained

by policy option) in the markets for reserves subject to limitation from availability of

interconnection capacity, which is the capacity remaining after the schedule of the unit

commitment and intraday. Resources not scheduled after the unit commitment and the

intraday can submit bids to the markets for reserves (only for tertiary reserve) but only

gas turbines are eligible for this purpose.

For the finalisation of the simulation, the unit commitment simulator is run again

assuming as given the schedule of units and interconnection flows resulted from previous

steps and the load (hourly). The objective function includes only penalties for deviation

from the schedule resulted from the previous step. The ascending order of penalties is

RES E, interconnection flows, gas, solids, nuclear, demand or another order defined

specifically by policy option. If must-take CHP and small-RES E can be curtailed then

they are also included with penalties, otherwise they are fixed. The unit commitment

simulator runs at this stage pan-European and applies flow based allocation of

interconnections. The purpose of this run is to calculate the production by plant,

consumption of fuel, operation cost by plant and emissions.

Demand response is modelled similarly to pumping transferring power from peak- to

baseload; the amount of energy reduced in peak hours is compensated in the same day by

additional energy consumption in other time segments, chosen endogenously. Therefore

demand response bids for differential demand reduction and demand increase at different

times, the bidding price reflecting costs (exhibiting decreasing return to scale), scarcity

cost opportunity and the bidding quantity being subject to potential. Demand response

(defined differently for each policy option) can be incorporated in all stages, i.e. DAM,

intraday, reserves.

The simulation cycle closes by the reporting of financial balances (load payments,

revenues and costs) for each generator, load and the TSO and calculating unit cost

indicators (e.g. for reserves, etc.). As the simulation is stochastic, the expected values of

the outcomes are calculated as the average of results by case of random events weighted

by the frequency of the case.

PRIMES / OM

PRIMES/OM is a modified version of the power sector model of PRIMES, tailored to the

needs of the impact assessment. It uses the PRIMES database, as well as its scenario

assumptions. By departing from the usual perfect competition assumption of PRIMES, it

can simulate investment behavior and the influence of CMs under various competition

regimes and bidding behaviours. Simulations are dynamic, demand is price elastic and

cross-border flows endogenous.

The model variant covers the power sector of all EU Member States linked together. The

model simulates an organized wholesale market, calculating prices, revenues and costs,

and estimating the probability of eventual mothballing of old plants and the cancelling

(partially or entirely) of investment in new plants as a consequence of the revenues

associated to the individual plant.

The model includes as an option a stylized CM auction, with or without cross-border

participation, which is general in scope in terms of eligibility and covers all dispatchable

generators. The inclusion or not of national CMs varies by scenario simulated. The model

considers that the presence of a CM leads to lower risk premium factors which are used

by generators to decide mothballing of old plants or cancelling of investments. However,

the CM demand functions, as specified according to the logic of the model, are such that

they may grant unnecessarily capacity payment to some plant categories.

The model runs dynamically from 2020 until 2050, in 5-year steps. It uses a full PRIMES

model scenario as starting point, from where it takes the first input for load, renewables

and the projection of power plant capacities. Subsequently it modifies load based on

demand response, capacity availability and investment (except for renewables, industrial

and district heating CHP) as a result of the mechanism described above.

A fundamental assumption of the oligopoly model is that the economics on which

capacity-related decisions are made by generators are specified individually for each

plant. However, the standard PRIMES model looks at the economics of portfolios of

plants to determine the outcome of capacity-related decisions. It also, enables us to

quantify the differences between market outcomes in perfect competition, where

marginal cost bidding is applied, and under the oligopoly market structure where uplift is

applied to the bids of market participants.

Main characteristics of PRIMES/OM

Investment Evaluation

–

A stochastic analysis is performed with respect to the main

uncertainty factors affecting investments or early retirement of old plants, thus

introducing a probability space for the simulation of investment decision under

uncertainty. These factors have been identified as follows: (a) ETS carbon prices, (b)

natural gas prices in relation to coal prices, and (c) the volume of demand for electricity

net of renewables. In addition to the uncertainties pertaining to the framework conditions,

the heterogeneity of decision makers in the investment evaluation process has also been

taken into account. This is accomplished by considering a distribution probability of the

hurdle rates that an investor considers (subjectively) for undertaking an investment. The

hurdle rates are equivalent to the minimum Internal Rate of Return value for deciding

positively upon an investment. The frequency distribution is modified in terms of mean

and standard deviation dependent upon the certainty or lack thereof of revenues;

292

Annex IV: Analytical models used in preparing the impact assessment.

kom (2016) 0863 - Ingen titel

revenues coming from the energy only market compared to those coming from a CM

imply higher mean and standard deviation of the distribution of hurdle rates.

Combining all of the above, a sample of about 100 combinations is generated around the

EUCO27 trajectory for the three stochastic factors for the whole time period (as vectors

over time) and 100 hurdle rate cases with combined probabilities. For the purposes of

investment evaluation, the pan-EU energy-only market is run for each sample of the

stochastic factors and revenues and costs for each plant are calculated for their total

lifetime, including possible extension of operation. Two sources of revenues are

accounted for: from operation in the energy-only market and from supplying reserve to

the system. For the cost calculation, capital annuity payments were excluded. Using the

revenues and costs calculated as such, the economic performance of each power plant is

found, defined as the present value of future earnings above operation costs for each

sample of uncertain factors and each hurdle rate case. The expected economic

performance of a plant is the result of an average of performances weighted by the

probabilities.

Heterogeneous decision makers, identified by the distribution of the hurdle rates as

mentioned above, have a different threshold probability in order to decide whether or not

to continue operating a plant or cancelling investment. In other words, there is an

association of expected economic performance of each plant, as represented by its

present value, with investment cost of new plants or with salvage value (remaining

capital value) for plants, which are distributed across the decision makers according to a

normal probability distribution function. Therefore, the frequency of decision about

survival of a plant’s capacity as a function of the economic performance

indicator is used

as the probability of survival. The capacity volume of the plant as projected by PRIMES

in the context of the EUCO27 scenario multiplied by the probability of survival provides

us with an update of the capacity volume.

Modelling of CMs

–

When a CM is assumed to be in place, it is modelled in a stylized

manner. All capacities are eligible, if dispatchable, including hydro lakes and storage,

provided that they are not under a different support scheme. For example, CHP, biomass,

etc. are excluded. Also, plants in the process of decommissioning or operating few hours

per year due to environmental restrictions as projected in PRIMES are excluded. All

capacities are remunerated for the available capacity excluding outages.

The CM payment is a result of an auction. The CM price is derived from the intersection

of demand for capacity and the offers, sorted in ascending price order. Demand for

capacity is defined as a negative-sloped linear line depending upon a price cap and

linking two capacity points: the minimum and maximum requirements. For all capacity

offered up to the minimum requirement the auction clearing price is equal to the price

cap, while for the maximum requirement it is equal to zero. The definition of the demand

curve takes into account trusted imports at peak load times and the guaranteed proportion

of exports. Therefore, implicit participation of flows over interconnections is taken into

account. Cross-border participation, when applicable, increases capacity offering.

Removal of capacities (due to mothballing or cancelling of investment, or because the

capacity is offered to a foreign CM) also decreases capacity offering. The CM winners

sign a reliability option (one way option) which has a strike price. If the wholesale

market price is above the strike price they are assumed to return the revenues above

strike price. The results of the CM auctions, namely the stream of revenues they provide

to generators, are taken into account by the oligopoly model in the final step of

investment evaluation.

293

Annex IV: Analytical models used in preparing the impact assessment.

kom (2016) 0863 - Ingen titel

Bidding Behaviour -

The model assumes a scarcity bidding function as a means to mimic

the strategic behaviour of market players in an oligopoly. The bidding function is specific

to each individual plant and it takes into account hourly demand, plant technology and

plant fixed costs in order to evaluate the hourly bid price of each generator.

In order to model the bidding behaviour of plants, they are assigned to one of four

different types of merit order: no-merit, baseload, mid-load, and peak load. Hydro-

reservoirs consider also water availability. The assignment of plants takes place based on

their technology as well as on whether they participate in the energy only market; non-

dispatchable generators are considered as must-take, and therefore are assumed to bid at

zero price. The no-merit order type is intended to include this type of plants. The

baseload category includes mainly nuclear and coal/lignite plants, the mid-load CCGTs,

and the peak load of GTs and Reservoir Hydro.

Subsequently, the capacities of all plants within a merit order type are summed up in

order to determine the total capacity of every type, developing a merit stack. Then the

hourly demand is compared with the merit stack in order to estimate for every hour

which merit order type is expected to be on the margin. This is the type on which a

scarcity mark-up will be applied, assuming this is the market segment in which all

strategic behaviour of market participants takes place for a specific hour. The marginal

cost which sets the basis for the price at which each plant offers its energy is calculated

based on variable cost data from the PRIMES database. The mark-up is calculated based

on the following equation:

[

]

P is the plant identifier,

the merit order type,

the Marginal cost,

the total

supply (capacity) of merit order type,

the hourly demand specific to merit order

type,

the price ceiling for merit order type,

the (inverse) rate of mark-up and

the scarcity bid. The demand specific to a generation type is calculated as the residual

of hourly demand minus the capacity of the merit order types which lie below the

marginal.

The price ceiling is specific to every merit order type and is applied in order to guarantee

that the merit order is never reversed, i.e. peak load plants being dispatched before mid-

load plants, mid-load before baseload, etc. Also, the rate specific to each plant is

dependent upon the fixed costs of the plant, which comprise mainly of capital costs, in a

risk averse manner. This convention is in place so that plants with high fixed costs are

more reluctant to apply a mark-up to their marginal cost in fear of staying out-of-merit

and not being dispatched due to the mark-up being too high. Finally, if in post-

calculation the scarcity bid exceeds the price ceiling, it is set equal to the ceiling.

Description of methodological approach followed concerning baseline

PRIMES EU Reference Scenario 2016

A common starting point to all Impact Assessments is the EU Reference Scenario 2016

('REF2016'). It projects greenhouse gas emissions, transport and energy trends up to

2050 on the basis of existing adopted policies at national and EU level and the most

recent market trends. This scenario was prepared by the European Commission services

in consultation with Member States. All other PRIMES scenarios build on results and

modelling approach of the REF2016.

294

Annex IV: Analytical models used in preparing the impact assessment.

kom (2016) 0863 - Ingen titel

Although REF2016 presents a comprehensive overview of the expected developments of

the EU energy system on the basis of the current EU and national policies, and could be

considered as the natural baseline for all impact assessments, it fails doing so for an

important reason. This scenario does not have in place the policies to achieve the 2030

climate and energy targets that are already agreed by Member States in the European

Council Conclusions of October 2014. It also does not reflect the European Parliament's

position on these targets.

Therefore, although it was important for all initiatives to have a common "context" in

order to ensure coherent assessments, each Impact Assessment required the preparation

of a specific baseline scenario, which would help assess specific policy options relevant

for the given Impact Assessment.

Central Policy Scenario: PRIMES EUCO27

Because of the need to take into account the minimum agreed 2030 climate and energy

targets (and the 2050 EU's decarbonisation objectives) when assessing policy options for

delivery of these targets, a central policy scenario was modelled ('EUCO27').

This scenario is the common policy scenario for all Impact Assessments. Additional

baseline and policy scenarios were prepared for each Impact Assessment, addressing the

specific issues to be assessed by each initiative, notably which measures or arrangements

have to be put in place to reach the 2030 targets, how to overcome market imperfections

and uncoordinated action of Member States, etc. A summary of the approach followed in

each respective impact assessment can be found in the Annex IV of the RED II impact

assessment.

This approach of separating a central policy scenario reaching the 2030 targets in a cost-

effective manner and other scenarios that look into specific issues related to

implementation of cost effective policies enables to focus on "one issue at a time" in the

respective separate analysis. It enabled to assess in a manageable manner the impacts of

several policy options and provide elements of answers to problem definitions listed in

the 2016 impact assessment, without the need to consider the numerous possible

combinations of all the options proposed under each respective initiative.

PRIMES EUCO27 scenario is based on the European Council conclusions of October

2014

. In particular, the following were agreed among the heads of states and

governments:

Substantial progress has been made towards the attainment of the EU targets for

greenhouse gas emission reduction, renewable energy and energy efficiency,

which need to be fully met by 2020;

Binding EU target is set of an at least 40% domestic reduction in greenhouse gas

emissions by 2030 compared to 1990;

This overall target will be delivered collectively by the EU in the most cost-

effective manner possible, with the reductions in the ETS and non-ETS sectors

amounting to 43% and 30% by 2030 compared to 2005, respectively;

295

kom (2016) 0863 - Ingen titel

A well-functioning, reformed ETS with an instrument to stabilise the market in

line with the Commission proposal will be the main European instrument to

achieve this target; the annual factor to reduce the cap on the maximum permitted

emissions will be changed from 1.74% to 2.2% from 2021 onwards;

An EU target of at least 27% is set for the share of renewable energy consumed in

the EU in 2030. This target will be binding at EU level;

An indicative target at the EU level of at least 27% is set for improving energy

efficiency in 2030 compared to projections of future energy consumption based

on the current criteria. It will be delivered in a cost-effective manner and it will

fully respect the effectiveness of the ETS-system in contributing to the overall

climate goals. This target will be reviewed by 2020, having in mind an EU level

of 30%;

Reliable and transparent governance system is to be established to help ensure

that the EU meets its energy policy goals, with the necessary flexibility for

Member States and fully respecting their freedom to determine their energy mix;

The above requirements, with a minimum energy saving level of 27%, are reflected in

EUCO27. Concrete specifications on assumptions were made by the Commission in

order to reach the relevant targets by using a mix of concrete and yet unspecified

policies. A detailed description of the construction of this scenario is presented in Section

4 of the EE impact assessment and its Annex IV.

As this scenario is not directly used in the present impact assessment, the reader is

referred to the relevant technical annexes of the EE and RED II impact assessments for

more details on its main assumptions and results. Table 1 below presents the main

projections for 2030 related to the power system for EU28.

Baseline: Current Market Arrangements ('CMA')

The Market Design Initiative addresses four different Problem Areas. The first two,

addressing market functioning and investments, share a common baseline which is highly

dependent on the context (e.g. based on REF2016 or EUCO27). The other two Problem

Areas, concerning risk preparedness and retail markets, are more independent of the

overall context, as in each case the envisaged baseline and options can apply in either

context (moreover the assessment tends to be mainly qualitative). Therefore the

discussion on the baseline is meaningful mainly for the first two Problem Areas.

297

Annex IV: Analytical models used in preparing the impact assessment.

kom (2016) 0863 - Ingen titel

Similar to the other 2016 Energy Union initiatives, EUCO27 was chosen as the starting

point (i.e. context) of the baseline for the Market Design Initiative (so-called "Current

Market Arrangements"

–

CMA). The EUCO27 scenario is the most relevant to the

objectives of the initiative, as it provides information on the investments needed and the

power generation mix in a scenario in line with the EU's 2030 objectives.

As all analysis focuses on the power sector, all assumptions exogenous to the power

sector were taken from the EUCO27 scenario. This also applied for the energy mix, the

power generation capacities for each period, the fuel and carbon prices, electricity

demand, technology costs etc. The main obstacle in further using the EUCO27 as a

baseline for this impact assessment was that it assumes a perfectly competitive and well-

functioning European electricity market, more matching the end point than the starting

point of the analysis. Therefore CMA differs from the EUCO27 scenario by including

existing market distortions, as well as current practices and policies on national and EU

level.

The CMA assumes implementation of the Network Codes, including the CACM and the

EB Guidelines (the later in their proposed form). It is assumed that the CACM Guideline

will bring a certain degree of harmonisation of cross-border intraday markets, gate

closure times and products for the intraday, as well as a market clearing. National

intraday and balancing markets will be created across EU and a certain degree of market-

coupling of intraday markets will be achieved. At the same time, the EB Guideline is

expected to bring certain improvements to the balancing market, namely the common

merit order list for activation of balancing energy, the standardisation of balancing

products and the harmonisation of the pricing methodology for balancing. Nonetheless,

other important areas like harmonisation of intraday markets and balancing reserve

procurement rules will not be affected by the guidelines.

The baseline does not consider explicitly any type of existing support schemes for power

generation plants, neither in the form of RES E subsidies nor in the form of CMs

. This

is governed to a large degree from the 2014 EEAG applicable as of 1 July 2014. Aid

schemes existing at that moment have to be amended in order to bring them into line with

EEAG no later than 1 January 2016. This with the exception of schemes concerning

operating aid in support of energy from renewable sources and cogeneration that only

need to be adapted to the EEAG when Member States prolong their existing schemes,

have to re-notify them after expiry of the 10 years-period or after expiry of the validity of

the Commission decision or change them. This implies that all existing schemes will

expire by 2024 at the latest and will be adapted to the EEAG, applicable at the time of

their notification. Current guidelines allows operational aid only as feed-in premium, not

attributed for the hours with negative prices and with its level determined via tenders. In

essence this means that non-market based support schemes are fully phased out by 2024

assuming that the rules as regards RES E and CHP aid schemes well remain unaltered

when the EEAG is reviewed in 2020.

Admittedly this assumption is strong, but necessary to simplify the analysis. Otherwise a riskier (for

the analysis) assumption would need to be made on the future share, type and level of support for the

various support schemes per Member States in the end becoming a major driver for the results and

complicating their interpretation.

298

Annex IV: Analytical models used in preparing the impact assessment.

kom (2016) 0863 - Ingen titel

Moreover, the RED II proposals (part of the baseline of the present impact assessment)

will enshrine and reinforce the market-based principles for the design of support

schemes. As it is reasonable to assume that the RED II will enter into force prior to 2024,

assuming that all support to RES E by 2030 is market based is a prudent assumption.

The effect of RES E subsidies is relevant to the MDI impact assessment only when it

directly affects the merit order. Overall the cost-efficient level of investments in RES E

is taken as given across all assessed options, as projected in EUCO27, without examining

how the costs of these investments are recuperated (topic addressed in the RED II impact

assessment). The baseline assumes one of the main objectives of the RED II initiative is

achieved and a framework strengthening the use of tenders as a market-based phase-out

mechanism for support is in place, gradually reducing the level of subsidies over the

course of the 2021-2030 period (still support schemes would exist for all non-competitive

RES E technologies). Moreover it is assumed that existing FiT contracts have been

phased-out by 2030 to a large degree, most importantly the ones targeted on biomass,

being the ones most distorting to the merit order. As a result the assumption of not

considering any non-market based support for RES E generation is reasonable and not

significantly affecting the results.

As for CMs, existing or planned, they are mainly relevant for Problem Area II and did

not need to appear in the common baseline of the two Problem Areas. The analysis for

Problem Area I did not touch issues related to investments, thus the assumption of CMs

(which would be present in all assessed options) would have a limited influence on the

impacts and the ranking of the options

. As far as Problem Area II is concerned, again

their inclusion was avoided, as any results would be highly dependent on the specific CM

assumptions over the examined period. Moreover, in line with the results of the analysis

in section 6.2.6.2, the effect of adding a CM would most likely be to further increase the

cost of the power system. As the baseline was already a very costly scenario compared to

the preferred energy-only market one, the conclusion from the comparison of the options

would remain the same.

METIS calibration to EUCO27

As mentioned above, for the scope of this impact assessment METIS was calibrated to

the PRIMES EUCO27 scenario. In fact, as the calibration needed to take place much

before the finalisation of the PRIMES EUCO27, it was performed on one of its

preliminary versions. The main elements of the calibration process, as well as the most

important differences between the preliminary and the final version of EUCO27 are

described below. A significantly more detailed description of the calibration has been

reported on a separate document, to be found on the METIS website

Preliminary EUCO27

The same applies for CHP, when the main use of those plants is the production of heat/steam.

The CMs would not affect the merit order in problem area I, as the analysis assumes bidding based on

marginal costs (not scarcity pricing, which is introduced in problem area II).

Once operational, the envisaged link is expect to be the following:

The two versions of EUCO27 are in general quite close from an EU energy system

perspective. Two differences can be found in 2030, one in the RES E shares and the other

in CO2 prices, slightly affecting power generation capacities and production.

RES E overall share is in both cases 27%, with a differentiation in the sectoral

contribution: in the preliminary version the share of RES E is at 48.4%, while being

47.3% in the final EUCO27 version. This was mainly driven by differences in off-shore

wind deployment. There is more switching from coal to gas in the final version. This is

translated to 2 p.p. increase of gas in the share of power gas generation, while solids

decreased by 0.5 p.p. and RES E by 1.3 p.p.. The CO

price, which was 38.5 EUR/tCO

in the preliminary version is 42 EUR/tCO

in the final EUCO27 version.

The effect of these differences is not very significant on the EU level, although it does

have some implication on the results of specific Member States with a projected high

capacity of off-shore wind in the preliminary version, e.g. the UK.

METIS calibration to PRIMES EUCO27

For the scope of this impact assessment, simulations adopted a country level spatial

granularity and an hourly temporal resolution of year 2030 (8760 consecutive time-steps

year), capturing also the uncertainty related to demand and RES E power generation.

Modelling covered all ENTSO-E countries, not only EU Member States, as follows:



All ENTSO-E countries for the day-ahead market;

EU28+NO+CH for intraday, balancing and reserve procurement

;

EU28+NO for regional co-operation for reserve procurement, CH reserve

assumed to be procured nationally.

For configuring METIS to match the (preliminary) PRIMES EUCO27 projections, a

number of steps were taken, the most important of which are described in the following.

Details can be found in the relevant METIS report

1. The data provided for the calibration concerned only EU28. Missing data for

other countries modelled with METIS (i.e. Bosnia, Switzerland, Montenegro,

FYROM, Norway and Serbia) were complemented by other sources, mainly

ENTSO-E 2030 vision 1 of TYNDP 2016.

2. The hourly power demand time series were based on ETNSO-E's 2030 vision 1

scenario. Data were adjusted so that on average (over 50 weather data

realizations) the power demand of each country corresponds to the PRIMES

EUCO27 projections.

3. Installed capacities were computed based on PRIMES EUCO27 scenario

. For

certain EU28 countries the split between hydro lake and run-of-river of PRIMES

Actually reserve procurement was not modelled for other non-EU28 Member States, as well as for

Malta, Cyprus and Luxembourg.

was reviewed based on historical data form ENTSO-E, due to differences in the

definitions used in PRIMES (based on Eurostat) and METIS (based on ENTSO-

E).

4. Generation of ten historical yearly profiles for wind and solar power was

performed according to the methodology depicted in Figure 5. The methodology

followed delivered annual load-factors closely matching the ones of PRIMES

EUCO27.

5. Thermal plant fleets comprised of the following technologies: hard coal, lignite,

CCGT, OCGT, oil, biomass. The various fleets, except oil and biomass, were

divided into two or three classes (only CCGT were divided into three). Thermal

installed capacities were based on PRIMES EUCO27, without though enforcing

any type of constraint on the net electricity generation of these plants (which was

a pure result of the modelling). The technical-economic assumptions of PRIMES

were used for the power plants, complemented by other sources or databases

when missing.

6. Water inflow profiles, as well as storage parameters, required important

reconciliation work combing data from ENTSO-E, TSOs and PRIMES.

7. The international fuel price assumptions of PRIMES EUCO27 were used for

calculating the marginal production costs of the thermal fleets. Specifically for

coal and biomass, end-user fuel prices coming again from PRIMES EUCO27–

including also transportation costs

–

were used instead.

CHP units were treated as electricity-only gas plants, as currently METIS does not model the heat

sector. Division of RES to small and large scale (e.g. rooftops solar) was also not captured.

8. METIS used the same NTC values as in PRIMES EUCO27

. NTC values

between European and non-European countries are completed using ENTSO-E

9. As METIS focuses in particular on the economics of security of supply, a key

point is that installed capacity is consistent with peak demand. Consequently,

provided OCGT capacities were optimized to satisfy security-of-supply criteria.

To optimize OCGT capacities, supply-demand equilibrium was computed with

“State of the art” OGCT capacities as variables over 50 years of

weather data.

Capacities of “oldest” OCGT fleets remain fixed to the installed capacities in

2000 which have not been replaced by 2030. Table 2 presents the results of the

OCGT capacity optimization consisting in the added OCGT installed capacities

per country. These additional capacities are added to the installed capacities in

2030 excluding the investment between 2000 and 2030.

METIS policy scenarios for the options of Problem Area I

This section provides information on the market design options that were modelled and

assessed using METIS. Each scenario was run using the full capabilities of METIS. In

fact certain aspects of METIS were further developed in order to be possible to better

assess a number of the measures covered in the impact assessment.

Each scenario was intended to match the setup of one assessed option. For this purpose

the options were first decomposed into a number of "fields", reflecting existing market

distortions or design features that were addressed within each option. Following

subsequent analysis, these fields were then narrowed down to the twelve presented in

Table 3 below. For each of these fields, two or three sub-options were considered across

the different scenarios. The sub-options considered (entitled "a"/"'b"/"c") are identified

on the right had columns of Table 3, while their description is provided in Table 4.

For all fields, sub-option "a" reflects current practices and existing market distortions, as

well as the possible evolution of markets in the near future in the absence of new

policies. The identification and methodology for the quantification of current practices

was supported by a study performed specifically for this purpose

- Regarding grid development and the interconnectors between countries, they are based on the ENTSO-

E TYNDP, following the respective timelines. After the end of the TYNDP, expansions are based on

known plans and the development of RES E.

Topic

Description of the options

Three levels of DR deployment (sub-options a, b and c, with

increasing economic potential, based on COWI BAU and PO2

scenarios

) were considered.

In sub-option "a" DR can considered only for countries where DR

has currently access to the market and only for industrial resources

based on BAU potentials. In sub-option "b" DR by industrial

resources appears in all countries based on BAU potentials. In sub-

option "c" all DR resources participate based on the potential of the

PO2 scenario, adjusted to better match EUCO27 projections and the

activation limits of DR potential.

Two options were considered:

a. Penalty factor for PV and Wind curtailment, priority

dispatch for Biomass

b. No penalty factor or priority dispatch for PV, Wind and

Biomass

For sub-option "a", modelling RES E priority dispatch for wind and

PV was performed via a penalty factor and not by explicit priority

dispatch. The reason was that there were a number of hours for

certain Member States that if an explicit priority dispatch was

enforced for all RES E, their power system collapsed (solution was

infeasible). In reality this would most likely be addressed by the

TSOs via the curtailment of RES E.

Two options for participation of biomass in reserve procurement:

a. Biomass does not participate in FCR or FRR

b. Participation of Biomass (the absence of priority dispatch is

a prerequisite)

Two options for coal and lignite unit commitment:

a. The day-ahead unit commitment decision (i.e. which plants

are turned on or off) for coal and lignite power plants cannot

be refined during intraday, i.e. coal and lignite plants are

treated as must-runs in intraday once scheduled in day-

ahead.

b. Coal and Lignite can re-optimise their commitment in

intraday (subject to their technical constraints).

By making RES E producers financially responsible for the

imbalances they are encouraged to improve their generation

forecasts. Two options were considered:

a. H-2 forecasts were used for Wind and PV generation for

reserve dimensioning and generation of imbalances.

b. H-1 forecasts were used for demand and PV, while 30 min

forecasts were used for Wind, leading to lower imbalances

and lower reserve requirements.

Description of the options

Auctions for interconnections capacity can either be explicit,

captured in METIS as if assuming the flows are fixed in H-4, or

implicit, in which case flows can be updated in H-1. Two options

were considered:

a. Auctions were mostly explicit, except in specific areas

based on current practices.

b. Auctions were implicit for all interconnections.

In any case, the reserve procured at day-ahead remained fixed during

intraday.

Two options were considered for aFRR reserve sizing:

a. Fixed reserve size computed as 0.1% and 99.9% centiles of

imbalance distribution over the year. While some Member

States have different reserve sizes depending on demand

variation, this option assumes that the reserve size is

constant over the year for all Member States.

b. Variable reserve size depending on the hour of the day and

wind energy generation. Size is computed with 0.1% and

99.9% centiles of imbalance conditional distribution

Reserve can be procured either day-ahead (which was modelled in

METIS as a joint optimization of power and reserve hourly

procurement at day-ahead) or on a fixed basis per year (in which case

the mean annual value of optimal reserve procurement is used). The

options were:

a. Current practices

b. Day-ahead procurement

Two options were considered for upwards and downwards reserve:

a. Joint procurement according to current practices

b. Being two separate products which can be procured

independently

To model the process of interconnection allocation, three options

were considered:

a. National TSOs need to have a high security margin. For the

scope of METIS, EUCO27 NTCs were reduced by 5%.

b. Collaboration between TSOs reduces the need for security

margins. EuCo NTC values were used.

c. The introduction of a supranational entities will result in a

further reduction of the security margins, leading to an

increase by 5% of the EuCO NTCs.

To assess whether risk sharing can reduce the needs for national

reserves, three options were considered. Reserve was sized using a

probabilistic approach:

a. At national level

b. At regional level

c. At EU level

In order to ensure Member States can face similar security of supply

risks when less reserves can be procured (Options b. and c.), part of

the interconnections' capacity was reserved for mutual assistance

between Member States.

Two options:

a. PV, Wind and Hydro RoR do not participate in FCR or FRR

A more detailed description of the scenarios, how each option/measure was modelled and

what were the identified relevant current practices, can be found in an explanatory

technical report

It is important to highlight that the scenarios under Problem Area I do not consider

explicitly the possible existence of capacity mechanisms nor support schemes for RES E,

focusing strictly on the wholesale market operation over the various time frames (day-

ahead, intraday, balancing). Nevertheless, certain assumptions (like priority dispatch for

biomass) would make economic sense only in the case of existing economic subsidies.

PRIMES/IEM policy scenarios for the options of Problem Area II

PRIMES/IEM scenarios were setup very similarly to the METIS scenarios. As can be

deduced from the description of the model, PRIMES/IEM puts more emphasis on the

simulation of the bidding behaviour of market participants and the modelling of the grid,

thus making it a better tool to capture the additional measures considered in Option 1 of

Problem Area II (on top of Option 1(c) of Problem Area I), i.e. the removal of low price

caps and the addition of locational price signals.

The consideration of market participant bidding behaviour and internal grid congestion,

made it necessary to re-run the baseline (Option 0) also of Problem Area I under these

new assumptions, in order to be used as the baseline of Problem Area II, with one caveat:

similar to METIS, PRIMES/IEM cannot model CMs. On one hand this implies an

underestimation of the benefits of the energy only market (Option 1) related to the more

efficient operation of the system. On the other hand the modelled baseline could not be

used for the comparison with Options 2 and 3. The approach followed to resolve this

issue is described in the next section.

In order to enrich the analysis, and provide more comparability with the analysis

performed for Problem Area I, it was decided to run also Options 1(a) (level playing

field) and Option 1(b) (strengthening short-term markets) of Problem Area I. For the

better understanding of the reader, the construction of these options is presented in a

similar manner as for the METIS scenarios, highlighting that Option 0 corresponds to the

baseline and Option 1(c) to Option 1 of Problem Area II. Options 1(a) (level playing

field) and 1(b) (strengthening short-term markets) do not correspond to any specific

option of Problem Area II, but are presented for completeness. The identification and

methodology for the quantification of current practices was supported by the same study

Measure Topic

Description of the options

Three levels of DR deployment (sub-options a, b and c, with increasing

economic potential, based on COWI BAU and PO2 scenarios) were

considered. Assumptions were similar to METIS. As load shifting and

load reductions could be captured in PRIMES/IEM, DR was modelled

also for the day-ahead (not only for balancing / reserves as in METIS).

Four sub-options were considered:

a. Priority dispatch for must take CHP, RES E, biomass and

small-scale RES E

b. As in (a), but biomass bids at marginal costs.

c. As in (b), with no priority dispatch of RES E except small

scale. RES E bidding at marginal costs minus FIT (wherever

applicable).

d. As in (c) but with no priority of small-scale RES E thanks to

aggregators.

Note that removal of priority dispatch is assumed to imply balance

responsibility and capability to participate in intraday and offer

balancing services. Thus for sub-option (d) all resources participate in

intraday, offer balancing services and have balancing responsibilities.

Three options were considered:

a. Low liquidity. DAM covers part of the load, with many

bilateral contracts nominated. ID illiquid in certain countries, in

which case TSO has significant RR.

b. Improved liquidity. DAM covers the large majority of the load,

no nominations. ID illiquid in certain countries, in which case

TSO has significant RR.

PRIMES/OM policy scenarios for the options of Problem Area II

As already discussed in the previous section, the technical difficulty to model

simultaneously specific wholesale market measures (removal of low price caps,

locational signals for investments) with the issues on the coordination of CMs led to a

two-step approach:

Initially PRIMES/IEM was used to model Option 0 and Option 1 of Problem

Area II. This was sufficient to show the benefit of Option 1.

Subsequently PRIMES/OM was used to model Options 1 to 3 of Problem Area II,

but not Option 0, this time the focus being on CMs. Comparison was performed

among these three Options.

Due to the limitations of PRIMES/OM, all the detailed measures and assumptions under

Option 1 could not be captured. Concerning bidding behaviour, the same approach as in

PRIMES/IEM was followed. Table 7 presents a short comparison of the main results

related to power generation for 2030 for the three models (PRIMES, PRIMES/IEM and

PRIMES/OM).

Apart from the differences in the installed capacities for solids and gas plants, explained

in more detail in Section 6.2.6.3, the main difference is the increased generation of gas

plants in detriment of solids and nuclear in PRIMES/IEM, most likely due to the better

capturing of the flexibility needs of the system.

With Option 1 described above, Options 2 and 3 assume on top the inclusion of CMs for

specific countries. Both Options assume CMs only in the case of Member States

foreseeing adequacy problems in their markets. Therefore certain Member States needed

to be chosen indicatively for this role. For the scope of this assessment, four countries

were assumed to be in the need of a CM: France, Ireland, Italy and UK. This assumption

was not based on a resource adequacy analysis, but on the CMs examined under DG

COMP's Sector Inquiry, focusing specifically on countries with market-wide CMs.

When a country was assumed to have a CM in place, it was assumed that generators no

longer followed scarcity pricing bidding behaviour, but shifted to marginal cost bidding.

As the reported technology categories of PRIMES do not entirely match PRIMES/IEM, for

PRIMES/IEM the reported figure in the table for oil fired generation includes peak units, steam

turbines (both oil and gas) as well as CHP with oil as main fuel.

310

Annex IV: Analytical models used in preparing the impact assessment.

kom (2016) 0863 - Ingen titel

Therefore in Options 2 and 3 a hybrid market was considered for EU28, with 24 Member

States having an energy only market (with scarcity pricing behaviour), while 4 Member

States having and energy market (with marginal pricing behaviour) supplemented with a

capacity mechanism.

Finally the only difference between Options 2 and 3, is that in Option 3 the CM is

assumed to include rules foreseeing explicit participation of cross-border capacities.

Cross-border capacities were assumed to participate to a CM up to a certain upper bound.

The main idea for this calculation of this upper bound was similar to the concept of

unforced available capacity, which is used in CMs for the generation capacities. Note

though that using this concept for calculating unforced available capacity (or de-rated

capacity) of interconnectors during system stress times is more complex because the

probability of non-delivery is not due only to technical factors but it is mainly due to

congestion factors, which can considerably vary depending on power trade circumstances

during system stress times. To do this calculation it was necessary to dispose simulation

results of the operation of the multi-country system. Alternatively, the calculation could

be based on statistical data on system operation in past years. In both cases, the

simulation requires calculation of power flows over the interconnection system.

Data collection and data gaps

The modelling performed for the impact assessment had significant data requirements.

For example METIS requires about twenty different types of data (such as installed

capacities, variable costs, availabilities, load factors and such). Depending on the type of

simulation, over 25 million individual data points can be required for each single test

case, mostly coming from hourly data (such as hourly national demands). For the NTUA

models an ever larger set of data was required (multiple times larger), as PRIMES covers

the whole European energy sector and all existing or emerging technologies, from

household appliances to industrial processes and means of transport. The respective data

were collected from public and commercial databases, as well as DG ENER EMOS

database.

Moreover, in order to assess the impact of various measures and regulations aimed at

improving the market functioning, one needs to compare the market outcome in the

distorted situation, i.e. under current practices, with the market outcome after the

implementation of new legislative measures. These distortions should be based on the

current situation and practices and form the baseline for the impact assessment.

For this purpose the Commission requested assistance in the form of a study providing

the necessary inputs, i.e. facts and data for the modelling of the impacts of removal of

current market distortions. Although a significant amount of data was collected, a large

number of desired data sets was either unavailable or undisclosed. This unavailability of

data sometimes applied only for specific Member States for certain series, creating

311

Annex IV: Analytical models used in preparing the impact assessment.

kom (2016) 0863 - Ingen titel

difficulties in using the collected data for the rest of the Member States. In these cases

proxies need to be defined that could fill in the data gaps

Modelling limitations

Every model is a simplification of reality. Thus, a model itself is not able to capture all

features and facets of the real world. While one may be tempted to include as many

features and options as possible, one has to be careful in order to avoid over-complication

of models. This can very quickly result in overfitting (i.e. modelling relationships and

cause and effects that do in this way not apply to reality, but yielding a better fit), and

transparency issues (i.e. understanding in the end not the model results, or drawing

wrong conclusions). It is therefore essential to find the right balance between complexity

and transparency, taking the strengths and weakness of each modelling approach into

account.

For these reasons, considering the limitations of each modelling approach, a number of

compromises were made. There was an effort these compromises to retain the complexity

of the modelling at the lowest possible level, in order to allo interpretability of results.

The aforementioned study on market distortions also contributed in identifying the best

modelling approaches to capture all major distortions.

One should also expect that the different models used, although all of them focus on the

power sector, can produce different results due to the varying methodological approaches

followed. As long as these differences are well-founded on the underlying methodology

and scope of each model, while being based on the same underlying assumptions and

input data, they can be considered as complementary, as they give a better overview of

the impacts of the various policy options and help producing a more robust assessment.

As the situation is very unclear how these will

advance in the coming years, and since modelling

requires a specific assumption for each of these

measures, it was decided for these cases (e.g. DR

participation in the markets) to reflect a more

pessimistic view, where only few advancements are

made. In this respect the costs of the baseline are quite

likely overestimated.

Leading to a possible underestimation of

benefits

The detrimental effects of capacity mechanisms or

support schemes for RES E to the efficiency of the

electricity market operation over the various time

frames, as well as the external costs to the power

system (in relation to the energy market), were not

considered.

Still these are touched in Problem Area II and the

RED II impact assessment, as well as strong

indication on the impacts of RES E subsidies can be

deduced by the effect of the removal of priority

dispatch for biomass plants.

The softer approach used for the modelling of

priority dispatch of variable RES E (wind, solar)

underestimates the relevant cost of the baseline

scenario. Similarly for the balancing responsibility,

where H-2 forecasts for RES E are used, even when

balance responsibility is not assumed to apply to

them.

METIS did not model CHP and small scale RES E

separately, which would further enhance the impacts

of priority dispatch, currently assessed only for

biomass.

The issue of the limited liquidity currently observed

in intraday and balancing markets is not captured in

the modelling. Thus METIS assumed that markets

would be liquid in 2030, which may very well be

indeed the case without any policy action. Note

though that in certain Member States these markets

may not even exist today,

With an unclear effect

Modelling of the day-ahead and reserve procurement is

based on the so-called co-optimization of energy and

reserves. This approach was the one implemented for

simplicity and transparency. At the same time though it

does lead to the optimal scheduling of units. This on one

hand underestimates the costs of the baseline (in the case

of METIS), but at the same time possibly over-estimates

the benefits of the policy options.

Still overall the specific choice should not be considered

pivotal. Well-designed markets should lead to the same

efficient operation of the power system. Liquid intraday

and balancing markets should optimize operation and

resolve possible infeasibility issues resulting from the DA

schedule.

The yearly dimensioning and procurement of reserves

overestimates the cost of current practices, not even

considering their possible evolution, based on which

are very likely to be brought even closer to real time in

the coming years.

This is partially compensated by assuming that

dimensioning is performed based on the more accurate

probabilistic approach (despite currently performed in

many Member States based on the deterministic one).

Also by the fact that in all sub-options dimensioning

of mFRR and FCR does not vary (thus no benefits are

reported for this).

Continuous intraday trading was modelled as consecutive

hourly implicit auctions.

assumed to be allocated and used relatively

efficiently.

Moreover the absence of network modelling implied

that all relevant (and in many cases significant) costs

were not considered, especially related to internal

congestion (within Member States).

DR was modelled as if participating only in

balancing markets and reserves, but not in day-ahead

/ intraday.

Benefits from load shifting or load reductions were

not assessed due to the lack of sufficient detailed

data.

A standard load profile was used for demand, based

on ENTSO-E's TYNDP 2016 assumptions. A

dynamic profile for demand and storage would better

capture the reactions of demand to market prices

(and the associated benefits).

Competition issues, effects of nominations and

block-bids, as well as possible strategic behaviour of

the market participants were not considered. On the

contrary, perfect competition was assumed based on

marginal pricing.

Assumed bidding behaviour on behalf of market

participants was not considered very aggressive, with

the electricity price rarely reaching the price caps.

Modelling required a significant amount of inputs and

exogenous assumptions, e.g. on market behaviour etc.,

with data not necessarily available (generally, not just

publicly).Moreover significant amount of data (e.g.

detailed data on RR, nominations, technical details on the

transmission grid) were missing, so had to be estimated by

the modellers. Thus results are quite dependant on these

inputs. Still every effort was made to confirm assumptions

based on currently observed market operation data.

The selection of the countries assumed to have a CM may

be influencing the results (in an uncertain direction). Each

combination of countries could possibly lead to different

results.

delegate

This would allow market parties to delegate the

balancing responsibility to third parties.

This option can be combined with the other

options.

The impact of this option would depend on the

scope and conditions of this delegation. A

delegation on the basis of private agreements,

with full financial compensation to the party

accepting the balancing responsibility (e.g. an

aggregator) generally keeps incentives intact.

The impact of this option would depend on the

scope and conditions of this delegation. A full and

non-compensated delegation of risks e.g. to a

regulated entity or the incumbent effectively

eliminates the necessary incentives. Delegation to

the incumbent also results in further increases to

market dominance.

Description

Shielding from balancing responsibilities

creates serious concerns that wrong

incentives reduce system stability and

endanger market functioning. It can

increase reserve needs, the costs of which

are partly socialized. This is particularly

relevant if those exemptions cover a

significant part of the market (e.g. a high

number of small RES E generators).

Most suitable: Option 2

combined with the possibility for delegation based on freely negotiated agreements.

Cons

Costs get allocated to those causing

them. By creating incentives to be

balanced, system stability is increased

and the need for reserves and TSO

interventions gets reduced. Incentives to

improve e.g. weather forecasts are

created.

Financial risks resulting from the

operation of variable power generation

(notably wind and solar power) are

increased.

This could allow shielding emerging

technologies or small installations from the

technical and administrative effort and

financial risk related to balancing

responsibility.

Most suitable: Option 2.

Sizing and procurement of balancing reserves across borders require firm transmission cross-zonal capacity. Such reservation might be limited by the physical

Removing distortions for liquid short-term markets

Objective: to remove any barriers that exist to liquid short-term markets, specifically in the intraday timeframe, and to ensure distortions are minimised.

Option 0

Business as usual

Local markets mostly unregulated, allowing for national

differences, but affected by the arrangements for cross-

border intraday and day-ahead market coupling.

Description

Stronger enforcement and volunatry cooperation

There is limited legislation to enforce and voluntary

cooperation would not provide certainty to the market

Simplest approach, and allows the cross-border

arrangements to affect local market arrangements. Likely to

see a degree of harmonisation over time.

Option 1

Fully harmonise all arrangements in local

markets.

Option 2

Selected harmonisation, specifically on issues relating to gate closure

times and products.

Would minimise distortions, with very limited

opportunity for deviation.

Targets issues that are particularly important for maximising liquidity of

short-term markets and allows for participation of demand response and

small scale RES.

Pros

Differences in national markets will remain that can act as a

barrier.

Extremely complex; even the cross-border

arrangements have not yet been decided and

need significant work from experts.

Additional benefit unclear.

May still be difficult to implement in some Member States with

implication on how the system is managed

Improving the coordination of Transmission System Operation

Objective: Stronger coordination of Transmission System Operation at a regional level

Option 0

BAU

Limit the TSO coordination efforts to the

implementation of the new Guideline on

Transmission System Operation (voted at the

Electricity Cross Border Committee in May 2016

and to be adopted by end-2016) which mandates the

creation of Regional Security Coordinators (RSCs)

covering the whole Europe to perform five relevant

tasks at regional level as a service provider to

national TSOs.

Lowest political resistance.

Option 1

Enhance the current set up of existing RSC by

creating Regional Operational Centers (ROCs),

centralising some additional functions at regional

level over relevant geographical areas and

delineating competences between ROCs and

national TSOs.

Option 2

Go beyond the establishment of ROCs

that coexist with national TSOs and

consider the creation of Regional

Independent System Operators that can

fully take over system operation at

regional

level.

Transmission

ownership would remain in the hands

of national TSOs.

Cons

Enlarged scope of functions assuming those tasks

where centralization at regional level could bring

benefits

A limited number (5 max) of well-defined regions,

covering the whole EU, based on the grid topology

that can play an effective coordination role. One

ROC will perform all functions for a given region.

This option will give every consumer the

right and the means (fit-for-purpose smart

meter and dynamic pricing contract) to fully

engage in price based DR if (s)he wishes to

do so.

Roll out of smart meters will remain

limited to those MS that have a

positive cost/benefit analysis.

In many MS market barriers for

demand response may not be fully

removed and DR will not deliver to

its potential.

Roll out of smart meters on a per customer

basis will not allow reaping in full system-

wide benefits, or benefits of economies of

scale (reduced roll out costs)

Incentive based demand response will not

develop across Europe.

Option 2: as Option 1 but also fully enable

incentive based Demand Response

In addition to measures described under Option

1, grant consumers access to electricity markets

through their supplier or through third parties

(e.g. independent aggregators) to trade their

flexibility. This requires the definition of EU

wide principles concerning demand response

and flexibility services.

This option will allow price and incentive based

DR as well as flexibility services to further

develop across the EU. Common principles for

incentive based DR will also facilitate the

opening of balancing markets for cross-border

trade.

As for Option 1, access to smart meters and

hence to price based DR will remain limited.

Member States will continue to have freedom to

design detailed market rules that may hinder the

full development of Demand Response.

Option 3: mandatory smart meter roll out and

full EU framework for incentive based demand

response

Mandatory roll out of smart meters with full

functionalities to 80% of consumers by 2025

Fully harmonised rules on demand response

including rules on penalties and compensation

payments.

This guarantees that 80% of consumers across the

EU have access to fully functional smart meters by

2025 and hence can fully participate in price based

DR and that market barriers for incentive based DR

are removed in all MS.

It ignores the fact that in 11 MS the overall costs of

a large-scale roll out exceed the benefits and hence

that in those MS a full roll out is not economically

viable under current conditions.

Fully harmonised rules on demand response cannot

take into account national differences in how e.g.

balancing markets are organised and may lead to

suboptimal solutions.

Most suitable option(s): Option 2.

Only the second option is suited to untap the potential of demand response and hence reduce overall system costs while respecting subsidiarity principles.

The third option is likely to deliver the full potential of demand response but may do so at a too high cost at least in those Member States where the roll out of smart meters is not yet

economically viable. Options zero and one are not likely to have a relevant impact on the development of demand response and reduction of electricity system cost.

interdependencies into account.

Difficult to coordinate the work as the

EU has 30+ TSOs.

Most suitable option(s): Option 3

introduction of resource adequacy measures in single Member States is justified.

Cons

Even in the presence of harmonised

methodologies

assessment

would not be able to provide a regional

or EU picture.

In addition to benefits in Options 1 & 2, it

would make sure that the national puzzles neatly

add up to a European picture allowing for

Results are more consistent and comparable as

one entity (ENTSO-E) is running the same
