Third regional generation adequacy assessment report published


This report provides the main findings of the third edition of the Pentalateral Generation Adequacy Assessment (PLEF GAA 3.0). The study was carried out by the electricity Transmission System Operators of the seven countries cooperating in the Pentalateral Energy Forum (PLEF): Austria, Belgium, France, Germany, Luxembourg, the Netherlands and Switzerland. The PLEF is the framework for regional cooperation in Central Western Europe towards improved electricity market integration and security of supply.


The study takes as basis the assumptions from the latest ‘Mid Term Adequacy Forecast (MAF)’ published end of 2019 by ENTSO-E and adds several sensitivities, which were defined by the TSOs, validated by ministries and consulted with regulators within the Pentalateral Forum. This has turned out to be a major added value for this 3rd Regional Adequacy Assessment to test the resilience of the region towards several sensitivities.


In addition to the latest ‘Mid Term Adequacy forecast’, the PLEF TSOs relied significantly on methodological evolutions by national TSOs within national studies. Compared to the second assessment, the usage of a flow-based (FB) model as the standard methodology for the considered time horizon (2025) and the consideration of the 70% minRAM requirements from the Clean Energy Package (CEP) are main areas of improvement of the methodology. The other aspects of the methodology are in line with the latest ENTSO-E MAF publication.
