Ofgem: Diamond Transmission Partners Leads Galloper OFTO Race

Ofgem has selected Diamond Transmission Partners as the preferred bidder to own and operate the high voltage transmission link to the Galloper offshore wind farm for the next 20 years.

Diamond Transmission Partners, a consortium comprising Mitsubishi Corporation and HICL Infrastructure Company Limited, was selected by Ofgem through a tender process in which bidders compete to become Offshore Transmission Owners (OFTOs).

The Galloper wind farm, located 30km off the coast of Suffolk, consists of 56 six megawatt (MW) turbines and has a capacity of 353MW. It became operational in March this year and can produce enough power for over 380,700 average UK homes.

The developer of the wind farm and the link is innogy SE. The wind farm is owned by a consortium comprising innogy SE, Siemens Financial Services, Sumitomo, ESB and a consortium managed by Green Investment Group and Macquarie Infrastructure and Real Assets.

The consortium’s initial estimated value of the transmission assets is £329.1 million. Once the final value of the assets has been agreed by Ofgem, the preferred bidder will pay this amount to the developer, once the bidder’s OFTO licence has been granted to them by Ofgem.
