ACER is organising a webinar to present the results of a consultancy study on how ACER’s (2020) methodology for adequacy metrics is being implemented. The methodology serves as a basis for determining the reliability standards of European countries.
When?
Wednesday, 5 June 2024, from 10:00 – 11:30 CET, online
What is resource adequacy and reliability standard?
A stable and ample energy supply is crucial for European consumers. Electricity security of supply depends on having adequate resources in the power system to meet the demand.
To maintain this level of security, Member States continuously monitor adequacy to ensure that the expected risk remains below the acceptable level. The power system is considered to have adequate resources when the risk level does not exceed the reliability standard. Member States define this acceptable or adequate level as a national reliability standard, based on the common methodology for adequacy metrics.
Why is this ACER methodology important for EU security of supply?
The EU methodology for adequacy metrics, developed by ENTSO-E and approved by ACER in 2020, is mandated by Europe’s 2019 Clean Energy Package legislation. It facilitates Member States in setting their electricity reliability standards based on how much consumers are willing to pay to ensure the security of electricity supply.
In line with the EU methodology, Member States determine their socio-economically efficient reliability standard based on:
The reliability standards are calculated based on these two values as a balance between the costs of additional capacity in the system and the benefits of reduced power outages.
What is the study about?
Through its monitoring of EU electricity supply security, ACER observed substantial discrepancies in the calculated metrics. The reasons of such discrepancies are not straightforward. To understand the underlying factors and to determine if further methodological coordination is needed, ACER commissioned consultants, Johannes Kepler Universität Linz and RWTH Aachen University, in August 2023 to conduct a consultancy study on the topic.
What are the webinar’s objectives?
The aim of this webinar is to present and discuss with stakeholders the main findings of ACER’s consultancy study, focusing on:
What are the next steps?
The consultancy study will be published on the ACER webinar page on 29 May 2024 as a pre-reading material for webinar participants.
ACER will analyse the study recommendations and the input from the webinar to identify potential improvements in how Member States determine adequacy metrics. This analysis will be included in the ACER security of supply report, scheduled for publication in Q4 2024.
