Capacity Calculation Regions

What are Capacity Calculation Regions?

Article 2 of CACM Regulation defines the capacity calculation regions (CCRs) as those “geographic areas in which a coordinated capacity calculation is applied”. Therefore, a CCR defines the set of bidding zone borders among which the tasks of capacity calculation are coordinated by the TSOs.

Pursuant to Article 15 of the CACM Regulation, all TSOs need to develop a proposal for capacity calculation regions and submit it to all regulatory authorities for approval and to ACER for information.

All TSOs fulfilled their obligation with a first proposal approved by ACER on 17 November 2016. The proposal is continuously updated to take into account the integration of the new interconnectors, the creation of new bidding zones or to include new countries.
