Operational Challenges at New 69 MW Solar-Plus-Storage Plant in Germany
A newly commissioned 69 MW solar-plus-storage hybrid plant in Brandenburg, Germany, faces operational limitations due to a dispute with grid operator Eon Edis, which has withdrawn previously agreed import capacity for the battery system. This restricts the 76.5 MWh battery to storing only on-site generated solar power, impacting its operational flexibility and revenue potential.
SolTraCo market update · · 3 min readProject Overview and Development
The hybrid power plant combines 69 MW of solar generation with a 76.5 MWh battery storage system and is located in Brandenburg, Germany, southeast of Löwenberg. The project took approximately four years for development, permitting, planning, financing, and construction. Technical approval for grid feed-in was granted in mid-August, with the official opening scheduled for September.
The battery system consists of 17 containers, with 14 located within the solar park and three at a dedicated substation built for the project, Bergsdorf-West. The solar plant is split into two sections, with 6 MW fully sold under Germany’s investment asset business model and 4 MW retained by the project company.
Grid Connection Dispute and Operational Impact
Local distribution network operator Eon Edis initially offered a connection agreement providing 6.8 MW of import capacity, including 800 kW for the solar plant’s own consumption and the remainder for battery operations and commercialization. Three battery containers were positioned at the substation to support this arrangement.
However, Eon Edis subsequently withdrew the agreed import capacity, restricting the battery to storing only electricity generated by the co-located solar plant. This limits the battery’s ability to operate as a grid-charged storage system and reduces potential revenue streams.
Project Operation and Legal Actions
The project is operated by Solarpark Löwenberger Land Betriebs GmbH & Co., with Solarpark Verwaltung I GmbH owning 96% of the operating company and the Pfitzmann-Freese farming family holding the remaining 4%. Suena Energy is responsible for optimizing and marketing the battery, with revenues used to refinance the investment.
Currently, the project has no power purchase agreement or flexibility purchase agreement in place. The operating company has sent a legal letter to Eon Edis seeking to restore the battery’s import capacity, which would allow the battery to operate as a grid-charged storage system and expand its revenue potential.
