Elexon explains the BSC's requirements for measuring and recording electricity flows, for Settlement purposes, at Offshore wind farms that are subject to the Offshore Transmission Regime. These are Offshore wind farms that connect onshore to the Transmission System or a Distribution System, where the Offshore transmission assets convey electricity from or to shore at or above 132kV.
