Eystrasalt Offshore Wind Farm

13 Apr 2023: Update 13/04/2023: A complete permit application to build an offshore wind farm on the Eystrasalt Bank has been submitted to the government by Skyborn Renewables Sweden (Skyborn). This marks the first permit application from the government for an offshore wind farm north of Stockholm. Update: not submitted as of September 2022; assume delayed to 2023. WPD intends to submit in early 2022 an application for a permit to construct and operate a wind farm of 286 turbines and associated infrastructure in the Swedish Economic Zone. The application will include the completed EIA. The export cable will require an additional permit for laying cable on the continental shelf, permits according to the Environmental Code and concessions according to the Electricity Act. These permits will be applied for at a later stage when the cable route and connection point to the overlying network have been determined.
