The Pentalateral Energy Forum (PLEF) provides the framework for regional cooperation in Central Western Europe (CWE) to improve electricity market integration and security of supply. The initiative aims to give political backing to a process of regional integration towards a European energy market. As far as the concrete implementation of impulses from the initiative is concerned, eight transmission system operators (TSOs) of seven countries cooperate in the PLEF, including the TSCNET shareholders APG from Austria, Amprion and TransnetBW from Germany, Swissgrid from Switzerland, the Dutch-German TSO TenneT, and TSCNET client Creos from Luxembourg as well as the Belgian TSO Elia and RTE from France.
The PLEF is subdivided in so-called Support Groups, e.g. covering work on market integration (SG1) and on security of supply (SG2). Within the scope of the SG2 group, the eight TSOs have worked out the third edition of the Pentalateral Generation Adequacy Assessment (PLEF GAA 3.0) and have just published a corresponding report, which summarises the main findings in 71 concise pages. The study, which examines the adequacy of electricity generation in the PLEF region up to the medium-term time horizon (2025), can be considered as significant result of TSO cooperation at regional level.
The main findings are that, under base conditions, sufficient production capacity is available, so that a breach of reliability standards is not to be expected and the adequacy of production in the CWE region will be up to standard by 2025. However, adequacy simulations have also shown that adequacy risks can occur. The electrical system may be exposed to specific situations in which the system safety is under strain. Additional unforeseen events in such situations can put even greater pressure on daily system operation, which may require the activation of special measures.
