Danish utility Orsted has signed a £3bn ($4bn) deal to sell half of the under-construction Hornsea 2 offshore wind farm in the UK to a consortium of investment firm AXA IM Alts and Credit Agricole Assurances.

The 1.3GW wind farm will be the world’s largest offshore array once it is commissioned later this year.

Orsted’s UK region head Duncan Clark stressed the importance of the giant wind farm for the UK’s commitment to decarbonise electricity by 2035.

“Orsted has invested more than £4bn in the UK to date, and when Hornsea 2 becomes fully operational later this year, our wind farms will be supplying over 7% of Britain’s electricity,” Clark said.
