Vattenfall has started construction of the Hommerdingen-Biesdorf hybrid wind and solar park in south-west Germany.
The project will combine four wind turbines supplied by Enercon, delivering a total capacity of 17MW, alongside more than 12,000 solar modules with a rated output of 7.6MWp. Commissioning is scheduled for autumn 2026.
The plant is being built across the municipal areas of Hommerdingen and Biesdorf in the Südeifel municipality, near the Luxembourg border.
Vattenfall said the solar installation will be connected to the distribution grid through the wind park using a single grid connection, in agreement with local network operator Westnetz. Technically, the solar park will be treated as if it were an additional wind turbine.
Philipp Heucke, head of onshore wind development at Vattenfall in Germany, said the complementary generation profiles of wind and solar would ease pressure on the distribution grid compared with stand-alone projects.
“This leads to more efficient use of the grid infrastructure and reduces the risk of grid overload,” he said. “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.”
