For energy geeks: world’s first offshore interconnection that is using national grid connections to offshore wind-farms
(from a press release)
European Commission confirms eligibility of revised technical concept for new Danish-German offshore interconnector
Energinet.dk and 50Hertz plan to establish a 400 MW offshore interconnection between national power grids
25 September 2015. Fredericia, Berlin. The European Commission has now granted the revised technical layout for the world’s first offshore interconnection that is using the national grid connections to offshore wind-farms. The “Kriegers Flak – Combined Grid Solution” is planned by the two transmission system operators Energinet.dk from Denmark and 50Hertz from Germany. The project will receive funding up to 150 million Euros from the European Energy Programme for Recovery (EEPR).
With the grant, the European Union underlines the importance of interconnectors for the formation of one common energy market in Europe. An integrated market enables energy production at lower costs and increases the security of supply. Additionally, the new connection helps managing both countries’ energy transitions by enabling the transport of renewable energy over long distances and cross-border.
The new interconnection is planned between the Danish region of Zealand and German Mecklenburg-Western Pomerania. It will have a capacity of 400 megawatts (MW). Operation is planned to start by the end of 2018.
“The new interconnection will contribute to guaranteeing the same high level of security of supply for consumers in Eastern Denmark going forward. It will allow producers and consumers to buy and sell more power across the borders. This adds more value to renewable energy and the green transition”, says Peder Østermark Andreasen, President and Chief Executive Officer of Energinet.dk.
“The approval by the European Commission is an acknowledgement to our work in integrating renewable energy sources with innovative approaches while strengthening the European electricity market. It shows that cooperation between the European transmission system operators is the right answer to the challenges of the energy transition. With the Combined Grid Solution we create the nucleus for an offshore grid in the Baltic Sea, a milestone in the development of European grids”, says Boris Schucht, Chief Executive Officer of 50Hertz.
Germany already has two offshore wind farms in the area, Baltic 1 (48 MW) and Baltic 2 (288 MW), while Denmark is currently preparing to erect the offshore wind farm Kriegers Flak (600 MW). The wind farms Kriegers Flak (Denmark) and Baltic 2 (Germany) are located less than 30 kilometres away from each other and will be connected by two submarine cables to establish the interconnector.
