CMA Final Determinations

28 October 2021

The CMA has today published a summary of its final determinations into SSEN Transmission's appeal against certain elements of Ofgem's RIIO-T2 price control settlement. The full final determinations and associated documents are expected to be provided to appellants and interveners later this week and then published by the CMA shortly thereafter.

SSEN Transmission welcomes that the CMA has upheld its appeals against the assumed 'Outperformance Wedge', and for changes to the Licence Modification Process.

However, SSEN Transmission is disappointed that the CMA has not upheld its appeals on the flawed Cost of Equity, or on changes to how Transmission Network Use of System Charges are recovered and the associated risk of under recovery this presents.

SSEN Transmission will continue to assess the full details of the CMA's final determinations as they become available and remains committed to work constructively with Ofgem and wider stakeholders as it continues to take forward ambitious plans to deliver a network for net zero.
