Walney Extension Limited, a joint venture owned by Ørsted (50%), PKA (25%) and PFA (25%), has completed the sale of transmission assets for the project to a consortium of Mitsubishi Corporation, HICL Infrastructure, and Chubu Electrical.

Diamond Transmission Partners Walney Extension is a partnership between Diamond Transmission Corporation Limited (a wholly owned subsidiary of Mitsubishi Corporation), HICL Infrastructure Company Limited and Chubu Electric Power Co., Inc.

The transmission assets hold an asset value of £446.6 million. The assets include the onshore substation, export cables, and the offshore substations.

The divestment takes place in accordance with the offshore transmission owner ('OFTO') regime. In March 2019, following a competitive tender, Ofgem selected Diamond Transmission Partners Walney Extension as preferred bidder for the Walney Extension offshore transmission licence.

The Walney Extension offshore wind farm is owned by Danish offshore wind giant Ørsted and a consortium consisting of PKA and PFA, two leading Danish pension funds. It sits alongside the existing and operational Walney Phase 1 and Phase 2 offshore wind farms 14km west of Walney Island off the coast of Cumbria, in the Irish Sea, England. The project features 87 turbines; 40 MHI Vestas V164-8.0MW units and 47 Siemens Gamesa SWT-7.0-154. It has a capacity of 656 MW, enough to be capable of meeting the electricity needs of more than 500,000 UK homes.
