We, alongside National Energy System Operator ("NESO"), are required to review the cost-benefit analysis ("CBA") supporting our decision to exempt the implementation of an automatic Frequency Restoration Process ("aFRP") in the GB synchronous area. Article 145(2) of Commission Regulation (EU) 2017/1485 establishing a guideline on electricity transmission system operation[1] ("the SOGL") requires that the CBA underpinning any decision to exempt a Transmission System Operator ("TSO") from implementing an aFRP be reviewed at least every four years.

Four years have passed since our initial decision to grant an exemption, and therefore NESO provided us with updated analysis on the costs and benefits and we have re-assessed whether this continues to support the case for exemption from implementation of an aFRP in the GB synchronous area. We have concluded that it is appropriate to continue the exemption. 

This letter sets out the outcome of our review and any necessary next steps.
