The goals are ambitious: By 2030, Prokon aims to increase its annual electricity production to around two terawatt hours. That corresponds to two billion kilowatt hours – effectively doubling the amount of electricity generated compared to 2022.
"I am very confident that we will achieve our goal,” says Christoph Rosengarten, Head of Project Development at Prokon. His team is responsible for the entire process: from site selection and lease negotiations to obtaining permits, planning construction, and commissioning new wind farms.
The Onshore Wind Energy Act obliges the federal states to designate two percent of their land area for wind power by 2032 – a clear boost for the industry. “In the past two years, many new areas have been designated, even in Bavaria,” says Rosengarten.
Prokon is benefiting from this tailwind: in 2024, the cooperative received permits for four wind farms with a capacity of 126.5 MW – the highest figure in seven years. A further 115 MW have already been added in 2025.
The total capacity of Prokon's wind farms currently stands at 1,076 MW – of which 685 MW are in Germany, 107 MW in Poland, and 283 MW in Finland. The most recent addition: the Friedersdorf wind farm in Brandenburg, with a rated capacity of 22 MW.
Looking ahead, strong growth is on the horizon: Prokon is currently preparing 642.8 MW, of which 441 MW are already in the approval process. "Each year, we submit five to ten projects, and in 90 percent of cases we receive approval," explains Rosengarten.
However, before construction can begin, tenders must be won and supply contracts with manufacturers concluded. In view of rising construction costs and fluctuating electricity prices, precise calculation is crucial.
"In 2025 alone, we received permits for wind farms with a total capacity of 115 MW. And we are expecting further approvals in the near future."

A bottleneck remains the grid infrastructure. In six out of seven current projects, Prokon has to build its own substation in order to feed electricity into the grid – an investment whose costs have tripled over the past three years.
Creative solutions help: in the repowering project Horst IV, Prokon is sharing the construction of a substation with two solar park operators. Nevertheless, timelines are being extended – coordination with grid operators alone sometimes takes up to a year.
In addition to grid-related matters, transport logistics and nature conservation requirements also demand great care:
increasingly larger rotor blades make transportation challenging.
For the new Nadrensee wind farm, Prokon is organising replacement habitats for cranes and marsh harriers.
Prokon also relies on the latest turbine models such as the Nordex N163, the GE 164, or the Vestas V162 – with outputs ranging from 6 to 7.2 MW per turbine. The decision as to which turbines are used where is made by wind experts based on detailed calculations.
“To achieve our expansion target, we continue to need political support and reliable framework conditions,” emphasises Rosengarten. The prospects are good: climate targets, rising CO₂ costs and the energy transition leave no alternative to the consistent expansion of renewables.
Prokon is on a clear growth path: doubling electricity production by 2030, new wind farms in Germany and Europe, as well as intelligent solutions for repowering and grid connection. The next terawatt hour is within reach.
