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.
