Sunotec advances Germany’s largest EEG hybrid power plant
Sofia-based solar and battery developer Sunotec announced a key milestone in the construction of the Hybrid Power Plant Zerbst. The company claims it is set to become Germany’s largest solar-battery hybrid power plant under the Renewable Energy Sources Act (EEG).
Located on a 41-hectare former gravel pit, the site combines 73,000 solar modules with a capacity of 46.4 MWp and a 57 MWh battery energy storage system (BESS).
The facility is designed and built to operate as a fully co-located hybrid asset, providing grid-supportive, dispatchable renewable power, Sunotec explained.
The project is being developed by Statkraft
The project is being developed by Statkraft. The Hybrid Power Plant Zerbst will deliver 50,000 MWh of renewable electricity per year. It is sufficient for 14,000 households.
This is the company’s first hybrid power plant in Germany and a proof of concept for its fully integrated, beyond-EPC delivery model, according to Sunotec.
The model is different from a traditional EPC contract. Sunotec implemented the core phases of the Zerbst hybrid power plant internally, including engineering, geotechnical assessments, and environmental planning.
Following completion, Sunotec will continue to manage the operations and maintenance of the PV plant.
Atanasov-Lankes: we demonstrate the strength of Sunotec’s integrated model
This integrated approach reduces interfaces, eliminates fragmentation, and guarantees high-quality delivery, the company said.
“With the Hybrid Power Plant Zerbst, we demonstrate the strength of Sunotec’s integrated model and our ability to deliver complex systems at scale,” Zharin Atanasov-Lankes, Managing Director of Sunotec Germany, stressed.
He underscored that the project reflects the engineering depth and execution capability of the firm’s teams.
Over the last six months, Sunotec has made major steps in developing its operations in Europe.
In November 2025 the company signed an agreement with oil and gas major Shell on the development of battery energy storage systems in Central Eastern Europe. In July it has agreed with China-based Sungrow to install 2.4 GWh of BESSs.
