RWE signs Thor connection agreement with Energinet

12 April 2022


Danish grid operator Energinet has signed an agreement with RWE concerning its Thor offshore wind farm. The agreement regulates the technical set-up, the power quality and the co-operation between RWE and Energinet, at the point of connection in Volder Mark. Thor will be built off the Danish west coast approximately 22 km from the port of Thorsminde, and with a planned capacity of around 1000 MW will be Denmark’s largest offshore wind farm to date.

To connect it to the grid, Energinet will construct a new 220 kV station – as part of the 220/400 kV conversion of the existing 400 kV station in Idomlund. From there, 28 km of cables will be laid underground to connect to a new 220 kV point of connection substation (POC) to be constructed at Volder Mark, which is located 4 km from the coastline. At Volder Mark the wind farm’s electrical output will be delivered to the grid. Full operation is planned for no later than 2027.

As something new for offshore wind in Denmark, developer RWE will construct and pay for the entire offshore electrical high voltage system up to the POC, and also pay for the onshore grid connection. This is regulated by a concession agreement signed with the Danish Energy Agency (Energistyrelsen) in January.

The Thor project will help to support RWE’s goal of tripling its global offshore wind capacity from 2.4 to 8 GW by 2030. RWE has a 27% share in the 207 MW Danish Rødsand 2 offshore wind farm, which is located south of the island of Lolland, approximately 10 km southeast of Rødbyhavn, and has been in operation since 2010.
