Wedoany.com Report-Oct. 1, EnBW has inaugurated a hybrid energy park in Gundelsheim, Baden-Württemberg, integrating solar, wind, and battery storage on a single site.

The solar park, rated at 58 MW and covering 55 hectares with 110,000 modules, is already operational and will supply electricity for roughly 30,000 households annually. A hybrid storage system combines 12 used Audi e-tron batteries with a sodium-ion unit, forming Europe’s largest installation of its type, with a 2.25 MWh capacity and 1.22 MW output. The Fraunhofer Institute for Solar Energy Systems leads research on the technology integration, with support from the German Federal Ministry for Economic Affairs and Energy.

EnBW CEO Georg Stamatelopoulos said: “In the right mix and on the right scale, this creates an integral energy system that strikes the right balance between cost-effectiveness, reliability and sustainability.”

The project also provides regional economic benefits through rental income, trade tax, and ecological enhancements, including wildflower strips, a wildlife corridor, and pond restoration. EnBW described Gundelsheim as a milestone in its renewables expansion, with 2025 expected to be the company’s largest year for new capacity additions.

This hybrid energy approach demonstrates how combining solar, wind, and advanced storage can optimize energy production, increase grid stability, and contribute to sustainable regional development.
