(17) Regulation (EU) 2019/943 provides for the use of a common methodology for the medium to long-term European resource adequacy assessment (from 10-year-ahead to year-ahead), with a view to ensuring that Member States' decisions as to possible investment needs are made on a transparent and commonly agreed basis. The European resource adequacy assessment has a different purpose from the short-term adequacy assessments which are used to detect possible adequacy related problems in short time-frames, namely seasonal adequacy assessments (six months ahead) and week-ahead to at least day-ahead adequacy assessments. Regarding short-term assessments, there is a need for a common approach to the way possible adequacy-related problems are detected. The ENTSO for Electricity should carry out winter and summer adequacy assessments to alert Member States and transmission system operators to risks related to the security of electricity supply that might occur in the following six months. To improve those adequacy assessments, the ENTSO for Electricity should develop a common probabilistic methodology for them, after consulting the relevant stakeholders, and in cooperation with ACER, and with the ECG, in its formation composed only of representatives of the Member States. The ENTSO for Electricity should propose that methodology and updates thereto to ACER, and ACER should approve the proposal and the updates. When consulting the ECG, ACER is to take the utmost account of the views expressed by the ECG. The ENTSO for Electricity should update the methodology where significant new information becomes available. The ENTSO for Electricity should be able to delegate tasks relating to seasonal adequacy assessments to regional coordination centres, while delegated tasks should be performed under the ENTSO for Electricity's supervision.
