The Swedish Government has granted a construction permit to Vattenfall, for the 640MW Kriegers Flak offshore wind farm.
The developer plans to install 40-50 turbines at a site in the Baltic Sea, 30km south of Trelleborg.
Further permits and a grid connection agreement must also be secured.
Vattenfall is planning for a possible investment decision in 2025.
The wind farm could be commissioned around 2028.
