Dortmund, Germany-based transmission system operator Amprion is preparing to enter the market to connect offshore windfarms to the grid, a move that could help alleviate well-known grid connection issues in the offshore wind market in the country.
The company is responding to a draft of an area development plan from the Federal Maritime and Hydrographic Agency (BSH) that includes two offshore grid connection systems that will be realised by the company.
The connections will be connected to the Hanekenfähr substation in Lower Saxony. Amprion will thus be responsible for the entire connection. The aim is to transmit wind power directly from the North Sea to major consumption centres in western Germany, relieving the burden on the grid in the north of the country.
Commissioning of the connections is planned for 2028 and 2029. The first will have a length of approximately 220 km, of which 50 km will be at sea. It will have a transmission capacity of 900 MW. The second will have a capacity of approximately 980 MW and will be 300 km in length, of which 130 km will be subsea.
The route for the connections has not yet been agreed, but Amprion said it plans to hold preparatory talks with public agencies in the first half of 2019. The company also plans to establish an offshore team in a project office in Hamburg.
Amprion commercial director Dr Hans-Jürgen Brick said, “Integration of offshore wind is a central element in the reorganization of our energy system but requires the appropriate regulatory framework that will enable economic implementation.”
