ACER workshop on CBCA Recommendation update (with targeted stakeholders)


In response to the energy crisis, every Member State introduced emergency measures to support their citizens and economy, and to mitigate security of energy supply risks.
Today, ACER publishes an inventory of 400+ measures adopted by Member States to cope with the energy crisis. ACER publishes its inventory in the form of an interactive dashboard, providing a high-level analysis of the measures. In a second step, ACER will proceed with an assessment of the measures, focusing on lessons learned and publishing a fuller report in July 2023.
ACER’s detailed EU-wide picture of the energy emergency measures adopted across Europe is timely:
Lessons from measures taken over the past year and a half could help Member States direct any future energy emergency support measures, when and where deemed appropriate, to those who need it most.
ACER plans to publish a fuller analysis of emergency measures in July 2023 to further assist policy makers.
As this ACER inventory might not be complete, ACER welcomes feedback on its inventory (by 16 April 2023), to be sent to 2023_emergency_measures(at)acer.europa.eu.
Some regions of Europe’s electricity single day-ahead coupling (SDAC) rely on so-called “second auctions” in case of extremely high or low prices. Those auctions, only triggered by extreme prices, allow market participants to adapt their bids prior to a second run of the SDAC auction.
Recently, Transmission System Operators (TSOs) and Nominated Electricity Market Operators (NEMOs) have introduced second auctions in the bidding zones of the Baltic region.
Hence, ACER would like to better understand how EU market participants consider the current functioning and potential evolutions of second auctions. ACER therefore invites EU market participants to fill in a survey by Thursday, 30 March 2023.

Europa Analytics is the corporate service, which monitors and evaluates the effectiveness and efficiency of the Agency’s Website (as well as that of other EU institutions).
It uses an open-source analytics platform, Matomo (formerly Piwik), fully controlled by the European Commission. This platform enables the protection of end-user personal data thanks to features such as IP address de-identification. On top of that, the Agency has created a feature to manage users’ consent to the collection of users’ browsing experience for aggregated statistics.
Europa Analytics is configured to use the second level domain europa.eu (used by the websites of European institutions) and to store first-party cookies.
Cookies (from Matomo) used by Europa Analytics (“pk_id”, that identifies unique visitors and expires in 28 days and “_pk_ses” that is used to temporarily store data for the visit and expires in 30 minutes) enable the European Commission to track the following information about visitors. We use this information to prepare aggregated statistics reports of visitors’ activity:
To improve the accuracy of the produced reports, information is also stored in a first-party cookie from our Website and then collected by Europa Analytics:
The European Commission retains full control of the data collected through first-party cookies by storing the data in servers fully owned and controlled by the European Commission itself.
Besides some session cookies, a random ID persistent cookie is generated by Matomo, which allows Europa Analytics to identify when a user returns to the site. This cookie has an expiration date of 13 months, after which it is automatically removed from the user's device.
By default, the browsing experience of our website visitors is NOT tracked by Europa Analytics. You may, though, choose to consent to contributing your browsing experience on our Website for us to produce aggregated statistics.

Since 13th January, as required by Council Regulation (EU) 2022/2576, ACER publishes a daily Liquefied Natural Gas (LNG) price assessment. On 8 March, ACER will start applying an updated version (Beta 2.0) of the methodology for its LNG price assessments.
This will increase the robustness of the LNG price calculation.
ACER works closely with stakeholders to have a meaningful LNG price assessment that is genuinely representative and not arbitrary. ACER developed and now subsequently refined, with the help of an LNG Expert Group and in consultation with the European Commission, a robust beta methodology underpinning the ACER LNG price assessment.
In addition, ACER intends to further update the Guidance on reporting LNG market data, and improve its TERMINAL platform to improve the user experience. The updated reporting Guidance will mainly clarify important details to assure better data quality.
Both updated documents will benefit from the advice of its LNG Expert Group, close engagement with market participants (e.g. via roundtables, webinars), input from other stakeholders and ACER price assessors’ experience so far.
Access the updated LNG price assessment methodology (Beta 2.0).
ACER and the European Securities and Markets Authority (ESMA) and have signed an updated Memorandum of Understanding (MoU) which strengthens collaboration between the two institutions. The MoU notably incorporates new cooperation areas under the Market Correction Mechanism (MCM) Regulation and benchmarks related to the energy sector. It also details the role of the recently established ACER–ESMA Task Force.
ACER and ESMA will continue to cooperate in relation to Regulation of wholesale energy markets, which encompass both energy derivatives and spot markets. The cooperation will primarily be achieved through on-going consultations, exchange of information and cross-participation in joint meetings of working groups and task forces.
ACER and ESMA have a long-established cooperative relationship. The first MoU was signed in July 2013.
In October 2022, in the context of the energy crisis, ACER and ESMA enhanced their efforts to strengthen oversight of energy and energy derivative markets. They launched the idea of a joint ACER–ESMA Task Force and highlighted possible areas of cooperation. More here.
ACER and ESMA published preliminary data reports concerning the adoption of the EU Regulation establishing an MCM to protect Union citizens and the economy against excessively high prices in January 2023. See ACER report here and ESMA report here. The provisions governing the MCM started applying on 15 February 2023.
Both agencies released on 1 March their respective Effects Assessments. See ACER report here and ESMA report here.
On 25 January 2023, the national regulatory authorities (NRAs) of all EU Member States, referred to ACER a joint proposal of all Transmission System Operators (TSOs). The proposal contains amendments to the methodology for calculating scheduled exchanges resulting from single day-ahead market coupling pursuant to Article 43 of Commission Regulation (EU) 2015/1222. ACER initiates the procedure and opens a public consultation.
The main amendments that TSOs propose are on how scheduled exchanges between the Nominated Electricity Market Operators (NEMOs) trading hubs are calculated.
ACER has 6 months (until 25 July 2023) to assess the TSOs’ proposal.
To collect the views of the stakeholders, a public consultation on the TSOs’ proposal runs from 1 to 29 March 2023. In particular, ACER is interested in:
