Vattenfall has started construction of the Hommerdingen-Biesdorf hybrid wind and solar park in south-west Germany.
Vattenfall said the project combines four Enercon wind turbines with a total capacity of 17MW and more than 12,000 solar modules with a rated output of 7.6MWp, with commissioning scheduled for autumn 2026.
The company stated that the plant is being built across the municipal areas of Hommerdingen and Biesdorf in the Südeifel municipality near the Luxembourg border.
Vattenfall added that the solar park will be linked to the distribution grid through the wind park via a single grid connection in agreement with local operator Westnetz, treating the solar installation technically as an additional wind turbine.
Philipp Heucke, head of onshore wind development at Vattenfall in Germany, said: “We are pleased to implement the combination of wind and solar together with our local grid partner Westnetz. The complementary generation profiles of wind and solar relieve the distribution grid compared to individual generation technologies. This leads to more efficient use of the grid infrastructure and reduces the risk of grid overload. In addition, the costs for the grid connection decrease significantly compared to stand-alone plants. This lowers the cost of renewable electricity and ultimately benefits customers.”
