Mainstream Renewable Power and Ocean Winds Partner on Second Scotwind Floating Offshore Wind Site
Mainstream Renewable Power (“Mainstream”), the global pureplay renewable energy company, and Ocean Winds, the international joint venture between EDPR and ENGIE dedicated to offshore wind energy, have partnered to develop a second ScotWind site of 500 MW east of Shetland, expanding the overall footprint of the Arven Offshore Wind Farm (“Arven”) to 2.3 GW.
Arven is comprised of two sites. The first is the 1.8 GW site east of the Shetland Islands which was awarded to the 50:50 joint venture between Mainstream and Ocean Winds as part of the ScotWind leasing process in 2022. Separately, Ocean Winds was awarded a 500 MW site in the same NE1 block. Mainstream has now completed its acquisition of a 50% shareholding in Ocean Wind’s holding company and the two sites are now being developed jointly to maximize their potential.
Mainstream and Ocean Winds have a longstanding partnership. The companies are currently developing a 1.2 GW floating offshore wind farm in South Korea and are in a consortium for the upcoming Utsira Nord floating offshore wind tender in Norway. By extending this partnership and developing the two sites off Shetland, Mainstream and Ocean Winds will leverage their combined expertise to maximize benefits for Shetland and Scotland, create supply chain opportunities and jobs, while contributing to the UK’s net zero ambition.
The partners have commenced early-stage local engagement, meeting with supply chain partners, local authorities, and fisheries representatives.
