In its cost assessment for the Walney Extension transmission assets, Ofgem notes that the value of the National Grid service agreement for the onshore substation was adjusted so that it covered costs only up to the point of first power, indicating that the Walney Extension transmission system had reached its first power export milestone by that stage. This adjustment was made as part of Ofgem’s review of economic and efficient costs for the onshore substation category within the Walney Extension OFTO project.
