The construction of Hessen’s largest solar park has begun in Wolfhagen-Niederelsungen in the state’s northernmost Kassel district. Spanning 74 hectares, it will be the seventh-largest solar park in Germany. The project is part of the ambitious Hydrogen Valley Wolfhagen energy park, which includes two wind parks with 13 wind turbines and a substation. It aims to be an important site for hydrogen production in the future.

The €58-million project, managed by BLG Solar Project, involves installing 160,000 solar modules on previously agricultural land along the A44 highway. The solar park, which is expected to be operational by March 2025, will generate about 97 megawatts of electricity, sufficient for approximately 38,000 two-person households. The wind park will add another 72 megawatts of power.

The project planners emphasize the dual benefits of Hydrogen Valley Wolfhagen: advancing green energy and boosting the rural economy. By involving local businesses, municipalities, and residents, they want to direct capital flow into the region, enhancing its attractiveness. In the future, Hydrogen Valley will produce a large amount of green hydrogen with green electricity from wind and solar power, which can be used, for example, to power heavy-duty transport trucks.

This project reinforces North Hessen’s leadership in decentralized energy. The area is among Europe’s top ten most innovative regions, known for its strong industrial and renewable energy sectors, dynamic investment behavior, and high innovation capacity. Institutions like the Fraunhofer Institute for Wind Energy and Energy System Technology (IWES) and the University of Kassel’s Institute for Decentralised Energy Technologies (IdE) contribute significantly to this innovation ecosystem.
