Sweden has a long coastline and high energy needs from industry, making it an attractive market for offshore wind development. The country has committed to fossil free energy production by 2045.

Mainstream has established a 50-50 joint venture with our partner Hexicon, named Freja Offshore, to develop the 2.5 GW Mareld floating offshore wind farm, off the west coast of Sweden.

About Freja Offshore

Located around 40 kilometers west of Lysekil, on the Swedish west coast, Mareld is expected to deliver 12 TeraWatt hours of electricity annually, when fully operational. This additional electricity production is long-awaited throughout western Sweden, whose electricity demand is expected to double by 2030 as a result of industry’s upcoming transition to electric power.

The County Administrative Board of Västra Götaland approved the Mareld floating offshore wind farm in June 2024, and the application is now awaiting approval from the Swedish government
