15.6.2013 EN Official Journal of the European Union L 163/1 COMMISSION REGULATION (EU) No 543/2013 of 14 June 2013 on submission and publication of data in electricity markets and amending Annex I to Regulation (EC) No 714/2009 of the European Parliament and of the Council (Text with EEA relevance) THE EUROPEAN COMMISSION, Having regard to the Treaty on the Functioning of the European Union, Having regard to Regulation (EC) No 714/2009 of the European Parliament and of the Council of 13 July 2009 on conditions for access to the network for cross-border exchanges in electricity and repealing Regulation (EC) No 1228/2003 (1), and in particular Article 18(5) thereof, Whereas: (1) Regulation (EC) No 714/2009, and in particular Article 15 thereof and point 5 of the Guidelines on the management and allocation of available transfer capacity of interconnections between national systems, set out in Annex I to that Regulation, lays down requirements for Transmission System Operators (TSOs) to publish data on the availability of networks, capacities of cross-border interconnectors and generation, load and network outages. (2) Article 4(4) of Regulation (EU) No 1227/2011 of the European Parliament and of the Council of 25 October 2011 on wholesale energy market integrity and transparency (2) recognises that publication of inside information in accordance with Regulation (EC) No 714/2009 or guidelines adopted pursuant to it constitute simultaneous, complete and effective public disclosure. (3) The availability of such data is indispensable for market participants’ ability to take efficient production, consumption and trading decisions. Deeper market integration and the rapid development of intermittent renewable energy generation sources such as wind and solar require the disclosure of complete, timely available, high quality and easily digestible information relating to supply and demand fundamentals. (4) The timely availability of complete sets of data on fundamentals should also increase the security of energy supplies. It should allow market parties to precisely match supply and demand reducing the risk for black-outs. As a result TSOs should be able to better control their networks and operate them under more predictable and secure conditions. (5) Current transparency measures do not fully satisfy these criteria. In addition, relevant market information is unevenly distributed among market participants with large incumbent players having exclusive access to information in relation to their own assets putting new market participants or participants without own assets at a disadvantage. (6) Market participants should be provided with timely information on the expected consumption. This information should be regularly updated and be provided for different timeframes. The actual outturn of the expected consumption should also be made available shortly after real time. (7) The planned and unplanned unavailability of power generation and consumption units is one of the most important supply-demand relevant information for market participants. Market participants and TSOs need to be provided with detailed information on where, when and why units are not or will not be available to generate or consume and when they are expected to return in operation. This should also help TSOs to better reallocate reserves reducing the probability for black-outs. (8) Market participants and TSOs should also receive detailed information about the overall installed generation capacity, estimations about total scheduled generation, including separately for intermittent generation, and unit level data about actual generation of larger production facilities. (9) In order to be able to move power from where it is available to where it is most needed and adjust portfolios accordingly, the market should be provided with information about planned and unplanned unavailability of existing cross-border transmission infrastructure and plans about infrastructure developments. TSOs should also provide and regularly update data on planned and offered cross-border transfer capacities for different time horizons as well as information related to the allocation and use of capacities. (10) Through the rapid deployment of intermittent generation sources away from consumption centres, transmission infrastructure has increasingly got congested in large parts of Europe. To relieve congestions TSOs have increasingly intervened in market operations instructing market participants to change their generation or trading commitments. In order to enable the market to understand where and why congestion management measures have become necessary, TSOs need to provide timely, detailed and reasoned information about their actions. (11) Even after careful planning producers, suppliers and traders may find themselves out of balance and be exposed to TSOs balancing and settlement regime. In order to optimally mitigate imbalance risk market participants need accurate, clear and timely information about balancing markets. TSOs should provide such information in a comparable format across borders including details about the reserves they have contracted, prices paid and volumes activated for balancing purposes. (12) TSOs are often the primary source of relevant fundamental information. They are also used to collect and assess large amounts of information for system operation purposes. In order to provide an overall view of relevant information across the Union, TSOs should facilitate the collection, verification and processing of data and the European Network of Transmission System Operators for Electricity (the ENTSO for Electricity) should make the data available to the public through a central information transparency platform. In order to make best use of existing sources of transparency, the ENTSO for Electricity should be able to receive information for publication through third parties such as power exchanges and transparency platforms. (13) Annex I to Regulation (EC) No 714/2009 should therefore be amended accordingly. (14) This Regulation has been adopted on the basis of Regulation (EC) No 714/2009 which it supplements and of which it forms an integral part. References to Regulation (EC) No 714/2009 in other legal acts shall be understood as also referring to this Regulation.

Summary: Electricity data — generation, transportation and consumption Electricity data — generation, transportation and consumption SUMMARY OF: Regulation (EU) No 543/2013 on the submission and publication of data in electricity markets WHAT IS THE AIM OF THE REGULATION? It aims to improve the transparency of electricity markets. It provides for the publication of electricity generation, transportation and consumption data. KEY POINTS The regulation requires the European Network of Transmission System Operators for Electricity (the ENTSO for Electricity or ENTSO-E) to set up a central information platform. The platform should be available free of charge to the public. Bodies responsible for submitting data must submit data on time and of the required quality to allow transmission system operators (TSOs) or other data providers to process and deliver the data on time to the ENTSO-E, so that it can meet its obligations to publish the information. The ENTSO-E maintains a manual specifying how data is to be standardised and shared, as well as technical and operational criteria and the appropriate classification of electricity production types. The data to be collected and published fall into the following categories: total load, i.e. all electricity generated or imported, after deducting any exports and power lost through energy storageunavailability of a consumption unit (a resource which receives electrical energy for its own use, excluding electricity operators themselves) of 100 MW or moreyear-ahead forecast margin, i.e. the difference between the yearly forecast of available generation capacity and the yearly forecast of maximum total loadtransmission infrastructure, specifically data on future changes to the network and interconnector projects including expansion or dismantling of transmission grids within the next 3 years, if they have an impact of at least 100 MW on capacity between bidding zones*unavailability of transmission infrastructure with at least a 100 MW impact on capacity, with an exception protecting the location of sensitive critical infrastructure covered by Article 2 of Council Directive 2008/114/ECestimation and offer of cross-zonal capacities, i.e. the capability of the interconnected system to allow energy transfer between bidding zonesuse of cross-zonal capacities, such as the capacity (in MW) requested by the market or allocated to the market, its price and the auction revenue per border between bidding zones, in accordance with a new schedule including the possibility of real-time reportingcongestion management measures including re-dispatching, countertrading and the costs involvedforecast generation, including generation capacity for all existing production units of 1 MW or more and information about production units (existing and planned) with a capacity of 100 MW or moreunavailability of generation and production units of 100 MW or moreactual generation output (MW) for each generation unit of 100 MW or more installed generation capacity, including actual or estimated wind and solar power generation (MW) and weekly average filling rates of all water reservoir and hydro storage plants (MWh)balancing, including the rules applied, the procuring processes for different types of balancing reserves and balancing energy, and the amount of balancing reserves under contract (MW) by operators. FROM WHEN DOES THE REGULATION APPLY? It has applied since 5 July 2013 with the exception of Article 4.1 (concerning publication) which has applied since 5 January 2015. BACKGROUND See also: Electricity production, consumption and market overview (Eurostat). KEY TERMS Bidding zone: the largest geographical area within which electricity market participants are able to exchange energy without having to allocate capacity.
