FREDERICIA, Denmark – Hornsea 1 Ltd., a joint venture owned by Ørsted (50%) and Global Infrastructure Partners (50%), has agreed to sell its transmission assets to Diamond Transmission Partners Hornsea One Ltd. (DTP).

DTP is a partnership between Diamond Transmission Corp. Ltd. (a wholly-owned subsidiary of Mitsubishi Corp.) and Chubu Electric Power Co. Inc.

The transmission assets hold an asset value of £1.175 billion ($1.625 billion). The assets include the onshore substation, export cables, the offshore reactive compensation substation, and three offshore substations.

The divestment takes place in accordance with the offshore transmission owner regime. In February 2020, following a competitive tender, Ofgem selected DTP as preferred bidder for the offshore transmission license for the Hornsea 1 offshore wind farm.

Ørsted will provide DTP with operations and maintenance services for the transmission assets under a long-term agreement.

Hornsea 1 is an offshore wind farm about 120 km (75 mi) off the Yorkshire coast. It consists of 174 Siemens Gamesa 7 MW wind turbines with an overall capacity of 1,218 MW. This is said to be enough to power more than one million British homes.
