The Kriegers Flak Combined Grid Solution, a of offshore wind farms into the power grids of two different countries will be the first of its kind. This has the advantage that up to the capacity of the connection the produced power can be transmitted to the country with the highest demand and price, improving the economy of the wind farms. Secondly, the connection between Denmark and Germany can act as an interconnector, so power can be transmitted fro. [pdf]
The Kriegers Flak - Combined Grid Solution is the world’s first hybrid interconnector/OWP system.
As part of the Combined Grid Solution project, Kriegers Flak is interconnected with the German wind farm Baltic II, which is located less than 30 kilometers southeast of Kriegers Flak. This allows for fossil-free energy to be shared between Denmark and Germany.
Kriegers Flak will take advantage of this and be connected both to the Danish grid as well as to the 288 MW ″EnBW Baltic 2″ which is connected via the 48 MW ″EnBW Baltic 1″ to the German grid.
The wind farm is serviced out of Vattenfall’s service facility at the Port of Klintholm on Møn, approximately 100 kilometres south of Copenhagen. With Kriegers Flak a milestone for a fossil-free energy has been accomplished. For the first time ever, an offshore power grid connects wind farms located in two different countries.
The extension of one of the two Kriegers Flak substation platforms at sea was required for the interconnector project CGS. The cables from all the wind turbines in the wind farm are connected in the transformer station at the transformer platforms. The voltage is transformed from 33 to 150 or 220 kilovolts (kV) for efficient further transport.
Kriegers Flak is located in the Baltic Sea, 15-40 kilometres off the Danish coast. "Flak" means reef, and this one is named after the Danish naval officer Christian Krieger, who in 1840 mapped the Baltic Sea. The offshore wind farm covers the annual energy consumption of approximately 600,000 households.

Wind farms undoubtedly alter the landscape. The turbines have become ever taller and the blades now reach lengths of up to 250 meters (820 feet). In good weather, the bright grey structures are certainly visible, but that also applies to other methods of power generation. Coal mining can swallow entire villages and raze. . In high winds, wind farms do become louder. Under full load, noise levels can reach up to 105 decibels at the turbine hub, which is 100 meters high. That's about as loud as an. . Sometimes the wind simply doesn't blow, meaning the rotors remain idle and no power can be generated. A reliable power grid therefore requires. . Wind farms, like roads and buildings, are an intrusion into nature in that they have concrete foundations dropped several meters into the ground. In addition, their blades can kill high. . A large onshore wind farm (6 MW) costs between €8 million and €12 million ($9-$13.5 million) to build, and produces electricity for 4 to 8 cents. [pdf]
Source: windwahn.com Onshore wind power production in Germany is poised to become the country's leading power source of the future and has seen an enormous increase in scale in the past years. Since the year 2000, the number of turbines tripled to almost 30,000 and average height nearly doubled to 130 metres.
Onshore wind power in Germany is expanding but growth still falls short of what's needed to meet the country's climate targets. Germany's onshore wind energy sector has made significant progress in 2023 compared to 2022, according to a half-year update from the German Wind Energy Association (BWE) and the trade association VDMA.
According to an earlier AEE survey published by strom-report.de, 52 percent of Germans would accept wind turbines in their immediate neighbourhood – still the second best rate for any form of power production after solar power, which 73 percent of those surveyed said they would tolerate.
Germany has been a leading market and incubator for onshore wind power throughout the 2000s and early 2010s, as eager investors and guaranteed state support helped bring the technology to scale. As of 2022, the country boasted the largest installed onshore wind capacity in Europe and the third largest globally.
Irrespective of the many challenges for turbine construction in recent years, onshore wind power since 2019 has become Germany’s single most important electricity source. The annual output has grown by 25 percent over four years until 2023.
In the first half of 2022 alone, about four percent of renewable power produced in Germany could not be used, according figures by Germany’s Federal Network Agency (BNetzA). Almost 60 percent of the cuts fell on onshore wind turbines and they mostly occurred in Lower Saxony, the state with the highest wind power capacity in Germany.
