In its decision 4/2021 of 7 May 2021, the European Union Agency for the Cooperation of Energy Regulators (ACER) has approved the Electricity Transmission System Operators (TSOs) proposal determining the Capacity Calculation Regions (CCR).
Pursuant to this Decision, the bidding zone border Sweden 4 – Germany/Luxembourg (SE4 – DE/LU) and the corresponding TSOs Svenska Kraftnät, TenneT TSO GmbH and Baltic Cable AB are included in the CCR Hansa.
The CCR Hansa now includes the bidding zone borders listed below as attributed to the referred TSOs:
a) Denmark 1 – Germany/Luxembourg (DK1 – DE/LU), Energinet and TenneT TSO GmbH;
b) Denmark 2 – Germany/Luxembourg (DK2 – DE/LU), Energinet and 50Hertz Transmission GmbH;
c) Sweden 4 – Poland (SE4 – PL), Svenska Kraftnät and Polskie Sieci Elektroenergetyczne S.A.;
d) Denmark 1 – Netherlands (DK1 – NL), Energinet and TenneT TSO B.V.;
e) Sweden 4 – Germany/Luxembourg (SE4 – DE/LU), Svenska Kraftnät, TenneT TSO GmbH and Baltic Cable AB.
The EU Regulation 2015/1222 establishing a guideline on Capacity Allocation and Congestion Management (CACM) defines CCRs as geographic areas in which coordinated capacity calculation is applied, it requires all TSOs to jointly develop determination of CCRs. The first determination of CCRs was adopted by ACER in November 2016 and was subsequently amended three times.
