Siemens Gamesa has tightened its partnership with Swedish developer Eolus and Hydro REIN with a deal to supply the 260MW Stor-Skälsjön project in central Sweden. The contract takes deals signed with Eolus to just over 450MW as they work to stimulate an energy transition across the Nordics. Hydro REIN is co-owner of the project with a 49% stake.
