Energinet's board gives the green light for Danish wind farm feasibility studies

Energinet's board has now officially approved that Energinet will start the projects for feasibility studies for offshore wind farms in North Sea I, Kattegat II and Kriegers Flak II. In a separate announcement it was revealed the board also approved feasibility studies for the revised location for the Hesselø Offshore Wind Farm.

The Minister for Climate, Energy and Supply instructed Energinet to start the feasibility studies for the four sites back in June 2022. The feasibility studies do not in themselves give the right to build offshore wind turbines, but it gives Energinet the opportunity to collect relevant information about the area for use by the Danish Energy Agency's tender for the offshore wind turbine area.

The preliminary studies at sea include, among other things, studies of the seabed, which should give the installers a good insight into where it is appropriate to establish the individual turbines and cables. The preliminary study also contains analyzes of wind, wave and environmental conditions, which may have an impact on the possibilities of establishing offshore wind in the area.

The order from the Minister for Climate, Energy and Supply does not contain a clear indication of which offshore wind farms are to be realised in North Sea I, Kattegat II and Kriegers Flak areas. It is expected that a political decision will be made on the geographical location of the offshore wind farms at the end of 2022. The three sites are expected to support arrays with a combined capacity of 6 GW.

The results of the studies will be published so that the companies that will bid to establish the offshore wind farm are aware of the conditions and the possible risks.

Energinet has also been instructed to prepare the establishment of onshore grid connection points for the North Sea I, Kattegat II and Kriegers Flak II sites.

In June 2022 it was also decided to move the Hesselø Offshore Wind Farm south to a new location. This happened after a fine screening from May 2022 showed that the area south of the original Hesselø area is a good alternative, as the seabed is considered to be better suited for setting up offshore wind turbines.

Energinet managed to start feasibility studies based on the original location. Therefore, the new feasibility studies must, to the greatest extent possible, be based on and reuse the feasibility studies that have already been carried out.

All studies, results and reports for the feasibility studies for Hesselø Offshore Wind Farm must be completed by the end of 2024 at the latest.

In addition, Energinet continues as previously planned with regard to the onshore project. However, the new feasibility studies will also mean a delay in the approval process for the land project.

The Hesselø Offshore Wind Farm is expected to be in operation by the end of 2029. It will have a capacity of between 800-1,200 MW. The winner of the tender is expected to pay for the completion of the studies.
