Ofgem has chosen Diamond Transmission Partners as the preferred bidder to own and operate the HV grid link for the 659MW Walney 3 offshore wind farm in the Irish Sea.
The OFTO preferred bidder will have to make “all necessary arrangements to provide offshore transmission services for the project, including having all relevant contractual, funding, regulatory and operational arrangements ready for the transfer of the transmission assets and the grant of the offshore transmission licence”, the UK energy regulator said.
Diamond Transmission Partners is a consortium of Mitsubishi Corporation, HICL Infrastructure and Chubu Electric Power.
Walney 3 was developed by Orsted and features 40 MHI Vestas 8.25MW turbines and 47 Siemens Gamesa 7MW machines.
Orsted owns 50% of the wind farm with Danish pension funds PKA and PFA each having 25% stakes.
The project was officially opened last year.
