The Swedish government has given Vattenfall permission lay subsea cables required to power the planned
Kriegers Flak wind farm in the southern Baltic Sea.  

The cables must be placed in the sea on the so-called continental shelf within Sweden's maritime territory and economic zone. The construction work required to lay out the cables must be completed within a ten-year period.

The permit is combined with a number of conditions that regulate how the construction works are to be carried out and that are needed in an effort to protect the environment against damage and to ensure safety. For the Kriegers flak wind farm, there are already several permits that are also required to be able to build and operate the park, including the government's permit according to the Swedish Economic Zone Act as well as the Land and Environment Court's permit according to the Environmental Code for works in water and Natura 2000 permit within the territory.

"Sweden needs all the fossil-free electricity production we can get to cope with climate change. This permit is important so that the work on building the wind farm at Krieger's flat can begin,"
said Climate and Environment Minister Romina Pourmokhtari.

"Offshore wind power has great potential to increase electricity production in Sweden in the coming years. That is why we are working intensively, so that we can give notice as soon as possible about the other permit tests for offshore wind farms that are currently being prepared in the Government Office,"
said Climate and Environment Minister Romina Pourmokhtari.

Located in the south of the Baltic sea, the Kriegers Flak project is the one of Vattenfall’s Swedish offshore wind projects that has come the furthest in its development. It will consist of up to 40 to 50 wind turbines with a total capacity of approximately 640 MW. In May last year the Swedish Government made the decision to grant Vattenfall a construction permit.

Vattenfall currently operates
a Danish project of a the same name. Featuring 72 Siemens Gamesa SG 8.0-167 DD wind turbines, the project is expected to provide enough power to cover the annual electricity consumption of approximately 600,000 Danish households.

The company is also planning a  350-400 MW cable that would enable interconnection of the Kriegers Flak CGS with the Swedish grid. The CGS links the national grids of Germany and Denmark through the interconnection of the  the
Baltic 1 and Baltic 2 wind farms (Germany) and Kriegers Flak wind farm (Denmark).
