Second regional generation adequacy assessment report published

The seven electricity transmission system operators (TSO's) in the Pentalateral Energy Forum (an inter-governmental initiative designed to promote collaboration on cross-border exchange of electricity in Austria, Belgium, France, Germany, Luxembourg, the Netherlands, Switzerland) are committed to contribute to the development of new methodologies and to investigate the security of the electricity supply – the serving of the electricity demand of all customers - on the regional level.

Compared to the first assessment, important areas of improvement include better representation of the grid by using a flow based (FB) approach, an improved model for taking into account flexibilities on the demand side, as well as use of the extended climate data from ENTSO-E covering historical weather from 1982 to 2015.
This PLEF GAA report provides results for winter 18-19 and winter 23-24. This first time horizon has been also addressed recently in two national reports published by Elia and the French (RTE) Transmission System Operator.
