Third regional generation adequacy assessment report published

Downloads & Contact

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 Transmission System Operators (TSOs) 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, which aimed to investigate the generation adequacy within the PLEF region up to the medium term (2025), is an important result of TSO cooperation at regional level.

De results from the PLEF GAA are in line and confirm the conclusions of TenneT's most recent national adequacy report (Rapport_Monitoring_Leveringszekerheid_2019), which states that generation adequacy in the Netherlands will meet the standard until 2025. There is sufficient production capacity in the Netherlands within this period to meet national electricity demand. Thanks to TenneT’s interconnections with neighbouring countries, the standard of four hours per year (shortage of electricity supply compared to demand) is not expected to be exceeded, even in extreme scenarios.
