Nordic TSOs' methodology for sharing and exchange limits of FRR/RR (amended)

Closed 1 Mar 2023

Opened 1 Feb 2023


This consultation concerns the amended methodology of all Nordic TSOs for sharing and exchange limits of FRR/RR between synchronous areas in accordance with Article 176(1), 177(1), 178(1) and 179(1) of the Commission Regulation (EU) 2017/1485 of 2 August 2017 establishing a guideline on electricity transmission system operation (SO Regulation).

The main trigger for this amendment is the implementation of markets that allow for exchanging FRR energy and capacity between synchronous areas. This development is expected to increase the exchange of FRR and accordingly change the operation on the HVDC interconnectors significantly. This amendment makes sure that the allocation constraints for exchange by day-ahead and intraday markets also apply to the balancing market. Furthermore, the amendment ensures secure operation on the HVDC interconnectors and confirms the responsibilities of the TSOs on FRR capacity.

The common proposal of the Nordic TSOs can be found below under the Related Documents.
