The European Union Agency for the Cooperation of Energy Regulators (ACER) publishes today a Decision establishing the common methodology for splitting long-term cross-zonal electricity capacity in Bulga​ria, Greece and Romania (the South East Europe Region). This methodology will foster a coordinated and more integrated usage of long-term capacity in the region.

The application of this methodology will follow the implementation of the long-term capacity calculation methodology for the South East Europe region. The latter was approved on 22 October 2020 by the regulatory authorities of the region, and should be implemented no later than 1 January 2023.

The European Union Agency for the Cooperation of Energy Regulators (ACER) published today a Decision​ on the methodology and assumptions to be used in the bidding zone review process and for the alternative bidding zone configurations to be considered, according to the EU Regulation on the internal market for electricity.

The proposed package for the bidding zone review was developed by the Transmission System Operators (TSOs) and was referred to ACER in July 2020 by the relevant regulatory authorities, as a unanimous agreement could not be found.

The Decision of ACER includes two key aspects:

• Approval of the bidding zone review methodology and assumptions to be used for the bidding zone review process, subject to the necessary amendments.

• A request to TSOs to provide results derived from a Locational Marginal Pricing (LMP) analysis to enable ACER to take a Decision on alternative bidding zone configurations. ​
