RWE and TotalEnergies have entered into an agreement to co-develop two major offshore wind projects off the coast of Germany, with a combined capacity of 4GW.

As part of the agreement, TotalEnergies will acquire a 50% equity stake in both projects from RWE.

This collaboration follows RWE’s success in securing the sites during Germany’s most recent offshore wind auction, held in August. At that time, it was announced that the two companies would explore potential joint development of the projects.

RWE Offshore Wind CEO Sven Utermöhlen said: “We are delighted to welcome TotalEnergies onboard as our partner in the delivery of these large-scale offshore wind projects in our home market of Germany.

“As a trusted partner in our Dutch offshore wind project OranjeWind, TotalEnergies shares our ambition to further drive the growth of offshore wind energy to accelerate the energy transition in Germany and beyond. Our RWE teams will bring their many years of experience and in-depth knowledge of the offshore wind industry to successfully develop and build the two wind farms.”

TotalEnergies Renewables SVP Olivier Jouny said: “We are pleased to strengthen our ties with RWE, a key player in renewables and our partner in OranjeWind project in the Netherlands.

“This new partnership contributes to our integrated development in the German electricity market, the largest in Europe, and will enable TotalEnergies to provide green electrons to decarbonize the country’s electricity and industry.”

Situated approximately 110-115km north-west of the German island of Borkum, the N-9.1 and N-9.2 sites are large enough to host offshore wind farms with a total capacity of 2,000 megawatts each.

Investment decisions for the projects are expected by 2027 (N-9.1) and 2028 (N-9.2), respectively.

Pending the necessary permits and confirmation of grid connections, offshore construction could commence in 2029 and 2030, with full commissioning scheduled for 2031 and 2032.

RWE currently operates 19 offshore wind farms, including six off the German coast.

Additionally, the company is constructing four large offshore wind farms: the Sofia offshore wind farm (1.4 GW) in the UK, the Thor project (1.1 GW) in Denmark, the OranjeWind offshore wind farm (795 MW) in the Netherlands in collaboration with TotalEnergies, and the Nordseecluster, which has a total capacity of 1.6 GW, located north of the island of Juist in Germany.

RWE aims to triple its global offshore wind capacity from 3.3 GW to 10 GW by 2030.
