According to the ex‑ante cost review for the Rampion offshore wind farm transmission assets, the Rampion transmission system, including the new onshore substation at Twineham and associated 400kV cables linking it to National Grid’s Bolney substation, was fully operational and commissioned by the end of 2018. These commissioned assets form the core of the Rampion OFTO, transmitting power stepped up from 150kV offshore to 400kV for integration into the National Electricity Transmission System.
