The hep global Group has completed the development phase for its largest solar project in Germany, the 35.7 MWp Buckelacker solar park in Eppingen, near its headquarters in Guglingen. The project, spanning approximately 30 hectares, is now entering construction and is expected to generate about 38 million kilowatt-hours of solar power annually. That output is theoretically enough to supply the annual energy needs of roughly 10,800 households with renewable energy, according to the company. The electricity will be fed into the regional power grid via a newly constructed substation at Hohenstein.
A key feature of the project is an integrated green energy storage system with a capacity of 20.3 MWh and an output of 10 MW. This addition expands the technical applications of the solar park and increases the economic benefits of the electricity generated. The storage system temporarily stores solar power and feeds it into the grid during periods of higher electricity prices, a strategy that can improve project revenues and support grid stability. For Germany, which is pushing to increase renewable energy capacity while phasing out fossil fuels, such co-located storage is increasingly important to manage intermittent solar generation and reduce reliance on conventional peaking plants.
The project also highlights hep global's strategy of bringing international experience to its home market. “This project is something special for us. It combines the development of a local solar project with the experience we have gained in various markets around the world,” said Benjamin Brasch, Manager of Project Development for South-West Germany at hep global. “The fact that we have developed our largest German solar project to date in the immediate vicinity of our headquarters also underscores our long-term commitment to the region.” The company has been active for more than 15 years in developing and planning renewable energy projects, mainly in Europe, Japan and North America, with a strategic focus on greenfield developments and the integration of battery energy storage systems. It employs around 120 people worldwide, with subsidiaries in Germany, Italy, Poland, the USA, Canada and Japan.
Construction work will be coordinated by ZaberSolar GmbH, and completion is expected in the first half of 2027. The successful completion of the development phase marks an important milestone for hep global, which is an internationally active specialist in solar projects and battery energy storage. As more countries seek to decarbonize their power sectors, projects that pair large-scale solar with storage can provide a blueprint for integrating renewables at scale while maintaining grid reliability. The Buckelacker project demonstrates how developers can leverage global experience to execute local projects, potentially accelerating the energy transition in Germany and beyond.
