ACER reviews the methodology for identifying regional electricity crisis scenarios

Intro News
On 8 January 2024, ACER has received an amendment proposal by ENTSO-E to amend the methodology for identifying regional electricity crisis scenarios.

ACER reviews the methodology for identifying regional electricity crisis scenarios

What is it about?

On 8 January 2024, ACER has received an amendment proposal by the European Network of Transmission System Operators for electricity (ENTSO-E) to amend the methodology for identifying regional electricity crisis scenarios.

What is the methodology about?

The methodology for identifying regional electricity crisis scenarios was first approved by ACER in 2020 under the EU Regulation on risk-preparedness in the electricity sector. The Regulation introduces a set of rules on how to prevent, prepare for and manage electricity crises, bringing more transparency in the preparation phase and during an electricity crisis and ensuring that measures are taken in a coordinated and effective manner.

The methodology introduces a structured approach for regional electricity crisis scenarios (prepared by ENTSO-E) and national ones (prepared by national competent authorities) and thus serves as a foundation for the development of consistent risk-preparedness plans.

What is the proposal about?

The key changes of the amendment proposal are:

  • Introducing a top-down process, starting with 31 regional electricity crisis scenarios, merging certain ones or adding new ones and focusing on extreme scenarios with regional impact.
  • Earlier engagement of Member States and competent authorities.
  • More pragmatic approach: ENTSO-E to undertake quantitative methods and model-based simulations where seasonal adequacy tools can be applied.

When approved, ENTSO-E shall use the methodology to identify the most relevant electricity crisis scenarios at regional level (including cross-border dependencies) and update the regional electricity crisis scenarios at least every four years.

What are the next steps?

ACER has 2 months (i.e. by 8 March 2024) to decide on the proposed amendment.

To make an informed decision, ACER will consult National Regulatory Authorities (NRAs), ENTSO-E and the Electricity Coordination Group (ECG) during the amendment process.

ACER unveils outcomes from its roundtable meetings on REMIT data reporting

What is it about?

ACER published today the minutes from its 2023 REMIT Roundtables.

On 15 and 16 November 2023, ACER hosted a series of Roundtable meetings on REMIT data reporting and transparency within wholesale energy markets. Joint and individual sessions took place, bringing together a diverse group of ACER’s stakeholders, including representatives from Associations of Energy Market Participants (AEMPs), Organised Market Places (OMPs), and Registered Reporting Mechanisms (RRMs).

What were the main discussion points?

  • Ongoing REMIT activities: emphasis was placed on the continuous improvement in REMIT data quality and the exponential growth of data received. Strategies for addressing related challenges and enhancement measures were also discussed.
  • Consultation on the REMIT transaction reporting guidance: this year's consultation addressed the updated transaction reporting guidance, focusing on clarifying the reporting of specific transactions and the introduction of a new Annex to the Transaction Reporting User Manual (TRUM) on the reporting of LNG supply contracts.
  • Revision of the REMIT data reporting framework: the discussion around this forward-looking topic focused on aligning regulatory practices with the evolving landscape of the energy market.

For more details on the topics that were discussed, check out the minutes of each Roundtable meeting:
