Mainstream and Ocean Winds win 1.8GW Scotwind site

Mainstream Renewable Power, the global renewable energy company, and Ocean Winds, the international company dedicated to offshore wind energy, have been appointed preferred bidder by Crown Estate Scotland for an area with the potential for a 1.8 GW offshore wind farm off the Shetland Islands in Scotland.

Mainstream and Ocean Winds, as the preferred bidders, are now offered the opportunity to enter into an option agreement for the site which is located east of the Shetland Islands in approximately 100m water depth and is well suited for floating offshore wind.

The project partners, which hold a 50-50 ownership, are committed to developing floating offshore wind on an industrial scale in Scotland, generating local jobs and opportunities in Scotland and the Shetland Islands. The site output is expected to power the equivalent of over two million homes and save three million tonnes of carbon emissions each year.

Commenting on the award, Mainstream’s Chief Executive Officer, Mary Quaney, said:
“This is a very significant win for Mainstream which plays to our key strengths as a global leader in floating offshore wind technology as well as our track record in offshore wind project development.

“In Scotland we have already developed the 450 MW Neart na Gaoithe Offshore Wind Farm and we now look forward to working with all stakeholders to further develop and strengthen Scotland’s offshore wind industry and help position it as a global leader in floating offshore wind power.”

Commenting on the partnership, Bautista Rodriguez, Ocean Winds’ Chief Executive Officer, said:
“We are proud of the strength that Ocean Winds and Mainstream Renewable Power teams have combined to secure this major new project.

“As Ocean Winds, we are looking forward to using our more than 10-year expertise as pioneer in floating offshore wind farms from development to operation to progress this large floating project awarded with Mainstream, as well as the 500 MW floating project also awarded to Ocean Winds during this clearing round. Both will bring major benefits to Shetland and Scotland, and an important contribution to Net Zero.”

Mainstream and Aker Offshore Wind recently completed a transaction to combine the two companies to create a stronger renewable energy company with more than 27 GW net portfolio.

Mainstream and Ocean Winds have been appointed preferred bidder for Lease Area 19

Combining Aker Offshore Wind’s strong technical and engineering capabilities and early mover position in floating offshore wind with Mainstream’s proven project development methodology, execution track record and global presence unlocks new opportunities worldwide.

The company is currently bringing forward multi-gigawatt scale developments of offshore wind assets in markets including Vietnam, South Korea, Japan, Norway, Ireland, the UK and Sweden.

Mainstream, through its recent combination with Aker Offshore Wind, has already partnered with Ocean Winds in the joint venture KF Wind in South Korea and is in a consortium to bid in the upcoming leasing round for floating wind at Utsira Nord in Norway. Mainstream and Ocean Winds are also major shareholders of the leading floating wind technology provider Principle Power.

Ocean Winds was created as a 50-50 joint venture in 2020 by EDP Renewables and ENGIE. The company is one of Scotland’s leading offshore wind developers, with 950 MW currently in operation at Moray East and 882 MW in late development stage at Moray West. In January 2022, Ocean Winds was successful in its ScotWind bid, the Caledonia Offshore Wind Farm, with a plan for up to 2GW.
