The owners of the 353MW Galloper offshore wind farm off east England have signed an agreement for the sale of the project’s transmission assets to Diamond Transmission Partners.
The transmission assets included in the sale comprise the Galloper offshore substation, two subsea export cables, and the Galloper onshore substation.
The 353MW Galloper wind farm is owned by Innogy, Siemens Financial Services, Sumitomo Corporation and ESB plus a consortium managed by Green Investment Group and Macquarie Infrastructure and Real Assets.
Innogy led the project’s development and construction and operates it on behalf of the project partners.
The divestment takes place in accordance with the Offshore Transmission Owner (OFTO) regime.
In November 2018, following a competitive tender, Ofgem selected Diamond Transmission Partners as preferred bidder for the transmission license for Galloper Wind Farm.
Galloper general manager Guy Middleton said: “The offshore transmission regulatory regime is competitive and allows generators to be partnered with the most efficient companies in the market.
“I’m delighted to have concluded the deal with Diamond Transmission Partners, one of the market leaders in OFTO operations, and look forward to our positive relationship continuing into operations.”
Galloper is located 27km off the coast of Suffolk.
