Hornsea 1 Ltd, a joint venture owned by Ørsted (50 %) and Global Infrastructure Partners (GIP) (50 %), today announced that it has signed an agreement for the sale of its transmission assets to Diamond Transmission Partners Hornsea One Ltd. 

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

Its transmission assets, reckoned at an asset value of GBP 1.175 billion, include the onshore substation, export cables, the offshore reactive compensation substation (RCS), and three offshore substations.

The divestment takes place in accordance with the offshore transmission owner ('OFTO') regime. In February 2020, following a competitive tender, Ofgem selected DTP as preferred bidder for the offshore transmission licence 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 in the UK, located approximately 120 km off the Yorkshire coast. It consists of 174 Siemens Gamesa 7 MW wind turbines with a total capacity of 1218 MW.
