The Agency for the Cooperation of Energy Regulators (ACER) has issued two decisions that amend the EU electricity balancing rules, focusing on the PICASSO platform and the balancing pricing methodology on all EU balancing platforms.
Launched in June 2022, PICASSO and one of three European electricity balancing platforms used by the Transmission System Operators (TSOs) of Germany, Austria and the Czech Republic, a number of inefficiencies have been observed, and there have been calls for rule changes to reflect demand of TSOs and better price setting.
ACER is therefore modifying the implementation framework that describes the design of the PICASSO platform, introducing the possibility for TSOs to use elastic demand “so that they can efficiently reflect the trade-off between extra costs and better frequency quality”.
ACER’s second decision modifies the method for computing the cross-border marginal price and the technical price limits in the pricing methodology, which establishes a harmonised approach for calculating prices across the EU balancing platforms.
European TSOs have one month to implement these changes.
