Thor Offshore Wind Farm

Background for the Project

As part of the Energy Agreement of June 29th, 2018 all political parties in the Danish Parliament have agreed to establish 3 new offshore wind farms before 2030.

The Thor offshore wind farm is planned to have a capacity of minimum 800 MW and maxi-mum 1000 MW and to be in full operation no later than ultimo 2027.The offshore wind farm will be established in the North Sea, west of Nissum Fjord, min. 20 km from shore and will be named “Thor” after the name of the town “Thorsminde”.

 

The gross area, which is located west of Thorsminde in the North Sea, and which is currently being pre-investigated, consists of a 440 km2 triangular area and additional areas around two potential export cable corridors leading to one landfall on the coast north of Nissum Fjord.

Site-investigations

Energinet is obliged to carry out site-investigations (geotechnical and geophysics) as well as MetOcean data collection for both the possible corridors in which the submarine cables can be placed as well as the 440 km2 project area appointed by the Danish Energy Agency (DEA).

Moreover, preliminary environmental assessments will be carried out, which are supple-mentary to the Strategic Environmental Assessment (SEA).

 

Access to results from the site-investigations

The results of the site-investigations as well as the reporting on the Strategic Environmental Assessment (SEA) will be made available according to the following table.

This table will be updated when new data is available.
