In addition to the sale agreement, Eolus and Mirova have entered into a 15-year asset management agreement and have agreed to jointly develop battery energy storage systems at each of the project sites.

“This deal is an excellent example of Eolus’s capacity to execute projects and deliver market-leading assets to investors. The team has successfully managed complex stakeholder relations to match the best wind resources in SE3, leading-edge Vestas technology, a solid PPA and timely construction execution to a top tier long-term investor in Mirova, a returning Eolus customer. We are grateful for the continued trust Mirova places in Eolus as we remain engaged to develop battery solutions and provide asset management services at these sites. We are pleased to cap 2025 with our fourth deal in as many quarters, heading into 2026 with a strong financial position and enhanced stay power.” comments Per Witalisson, CEO of Eolus.

“We are delighted to acquire these projects from Eolus, a trusted historical partner with whom we have already successfully invested in and managed projects in Sweden. These high-quality assets with robust technology and protective PPA are an ideal investment to strengthen our presence in Northern Europe and participate to the diversification of our €1.2bn MET6 portfolio.” adds Raphael Lance, Global Head of Private Assets, Mirova
