European Resource Adequacy Assessment 2025

Overview

Will demand for power in Europe be covered in the next decade by adequate supply? This is a key question addressed in ENTSO-E’s European Resource Adequacy Assessment (ERAA): a state-of-the-art pan-European monitoring assessment of power system resource adequacy of up to 10 years ahead.

The ERAA has been a leap forward in system modelling - it is based upon state-of-the-art methodologies and probabilistic assessments, aiming to model and analyse possible events which can adversely impact the balance between supply and demand of electric power. It considers the impact of climate change on the European power system and various interdependencies between European countries which are essential in assessing security of supply.

Why your views matter

ENTSO-E relies on the contributions of stakeholders to develop the ERAA. ENTSO-E has regularly consulted with stakeholders during the development of this 2025 assessment. ENTSO-E now organizes a public consultation of stakeholders to gather feedback on the ERAA 2025 report and further the improvement of the ERAA. 

Following the methodologies as approved by ACER on 2 October 2020, the ERAA is a key tool for the detection of adequacy concerns at a pan-European level. The ERAA aims to provide stakeholders and policy makers with the data and insights necessary to make informed, qualified decisions and promote the development of the European power system in a reliable, sustainable and connected manner. It is an important element for supporting qualified decisions by policy makers on strategic matters such as how to address adequacy concerns in the longer run.

ENTSO-E consults stakeholders on its European Resource Adequacy Assessment (ERAA) as part of the process to fulfil Regulation (EU) 2019/943 ('Electricity Regulation') legal requirements.
