Vattenfall has started construction of the Hommerdingen-Biesdorf hybrid energy plant in southwestern Germany. The project will be the company's first combination of wind and solar energy in Germany.
This is stated by Vattenfall in a press release.

The plant consists of four wind turbines from Enercon with a total output of 17 MW and more than 12,000 solar modules with a total output of 7.6 MWp. The park is being built in the municipalities of Hommerdingen, where the wind turbines will be located, and Biesdorf, where the solar plant will be established. Both areas are located in the Südeifel close to the border with Luxembourg. The plant is scheduled to be put into operation in the fall of 2026.

Instead of establishing a separate grid connection for the solar park, it will be connected to the distribution grid via the wind park in cooperation with the local grid operator Westnetz. This means that the entire system only requires one overall grid connection, as the solar farm is technically treated as an additional wind turbine.

- We are pleased to implement the combination of wind and solar together with our local grid partner Westnetz. The complementary production profiles from wind and solar relieve the distribution grid compared to stand-alone technologies. This provides a more efficient use of the grid infrastructure and reduces the risk of overload. At the same time, the costs of grid connection are significantly reduced compared to stand-alone plants. This lowers the price of renewable electricity and ultimately benefits customers, says Philipp Heucke, Head of Onshore Wind Development at Vattenfall in Germany.

Vattenfall already operates a hybrid plant in the Netherlands, Haringvliet, where wind and solar energy are combined with battery storage. In Germany, the company plans to supplement solar farms in particular with battery solutions depending on local conditions.
