Closes 6 Jun 2022

Opened 6 May 2022


This consultation concerns the Amended Nordic Synchronous Area Methodology for Additional Properties of FCR in Accordance with Article 154(2) of the Commission Regulation (EU) 2017/1485 of 2 August 2017 establishing a guideline on electricity transmission system operation (SO Regulation).
