Energinet.dk has received approval from Danish energy, utilities and climate minister Lars Christian Lilleholt to invest in a new interconnection between the Eastern Danish and German electricity grids through the Baltic Sea.
The total budget of the interconnection is approximately €320m.
Any investments in the transmission grid exceeding kr100m ($14.9m) need to be approved by the minister, as per the Danish Act.
With a capacity of 400MW, the connection is a joint project between Energinet.dk and the German transmission system operator 50Hz.
It is claimed to be the world’s first interconnection between two countries, which also connects offshore wind farms of both countries.
Based on Energy 2012 agreement, the Danish offshore wind farm will be connected to the submarine cables, which run from the German side to the two German offshore wind farms Baltic 1 and Baltic 2.
The unique combined grid solution (CGS) will export electricity from power stations, onshore wind turbines, solar cells, in addition to transport electricity from three offshore wind farms to consumers in the two countries.
There is a need to build facility in Bentwisch, as the interconnection connects two different electricity areas. It helps to synchronise electricity from the Eastern Danish and German systems.
The approval allows the Danish-German project to start entering contracts with suppliers. It is expected to be operational by the end of 2018.
Earlier, Energinet.dk had received the minister’s approval to invest in the landing facilities of the Kriegers Flak offshore wind farm.
