Ofgem chooses preferred bidder for Galloper offshore wind farm


November 25, 2018 – British independent energy regulator 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 consisting of Mitsubishi Corporation and HICL Infrastructure, has been selected by Ofgem through a tender process in which bidders compete to become Offshore Transmission Owners (OFTOs).

Located 30km off the coast of Suffolk, the Galloper wind farm consists of 56 6MW turbines and has a capacity of 353MW.

The wind farm became operational in March 2018 and can produce enough power for more than 380,700 average homes in the UK.

German energy company innogy is the developer of the wind farm. The wind farm is owned by a consortium comprising innogy, 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 £329.1m, and once Ofgem agrees on the final value of the assets, Diamond Transmission Partners will pay the amount to the developer after Ofgem grants the bidder’s OFTO licence.

The reserve bidder for the project is Mari Energy Transmission.


The OFTO regime was launched in 2009 by Ofgem and the government, and since then, winning bidders have invested more than £3.3bn in links and generation assets, connecting more than 5GW of offshore wind farms.

Tendering ownership of these links through the regime reduces the cost of connecting offshore wind. At least £700m in savings have been achieved for consumers so far across the first three tender rounds.

The Galloper wind farm link is part of tender round five, which started in 2016. Other links are to the Dudgeon, Race Bank, Walney Extension and Rampion offshore wind farms.

The invitation to tender stage for Walney Extension is currently running and will shortly commence for Rampion.

A licence has been awarded for the Dudgeon link in November 2018 and a preferred bidder for the Race Bank link was announced in June 2018.
