Nordic TSO's proposal on FCR dimensioning

Closes 6 Jun 2022

Opened 6 May 2022


This consultation concerns the Amended Nordic synchronous area methodology for the dimensioning rules for FCR in accordance with Article 153 of the Commission Regulation (EU) 2017/1485 of 2 August 2017 establishing a guideline on electricity transmission system operation (SO Regulation).

The common proposal of the Nordic TSOs can be found below under the section Related Documents. A related common proposal of the Nordic TSOs has been developed to implement updates to the additional properties of FCR. That proposal is being consulted in parallel to this proposal on dimensioning of FCR.

The separate proposal on additional properties of FCR necessitates corresponding updates to the dimensioning of FCR, which has been implemented in this proposal now under consultation. The contents of both proposals have been presented and discussed at a stakeholder event on the 28th of March.

The proposal is subject to public consultation according to article 11 of the SO Regulation.
