Hybrid PV-storage project secures PPA and battery tolling agreements in Germany

Enertrag has signed long-term commercial agreements for a hybrid project combining a 44.5 MW solar plant with a 5 MW/10 MWh battery energy storage system (BESS) in Brandenburg, Germany.

Energy trader EDF Trading will purchase and market the solar output under a seven-year power purchase agreement (PPA), while German flexibility trader e2m will manage the battery under a seven-year tolling agreement. The battery will initially operate as a green electricity co-location asset for five years before switching to a gray electricity co-location model for the remaining two years.

The Brüssow project is designed to maximize use of a constrained grid connection by adding solar and battery storage to an existing connection already serving 33 MW of wind capacity and an approximately 20 MW battery energy storage system. The new assets will use the remaining available grid capacity rather than requiring a dedicated connection.

Enertrag, EDF Trading, and e2m said the integrated commercial structure is intended to optimize project economics while providing long-term revenue certainty.

e2m said the project demonstrates how combining renewable generation, battery flexibility, and tailored marketing arrangements can improve the commercial viability of hybrid assets, particularly where multiple technologies share a single grid connection.
