The project is a joint venture between Shell plc subsidiary Shell Renewables and Energy Solutions (formerly Shell New Energies US LLC) and Ocean Winds (a global offshore wind collaboration of Engie and EDP Renewables). Fugro conducted a high‑resolution Geo‑data acquisition project in the lease area and along the export cable routes.[3] Ventoline will advise on construction and cabling.[4] Bladt Industries and Semco Maritime will construct the offshore substation.[5]
In early 2023, authorities approved a Power Purchase Agreement at 7c/kWh, however contracters viewed the agreement as insufficient.[6]
It will connect to the grid at the former Brayton Point Power Station.
