The Engie -Kraftwerksgruppe Pfreimd – Battery Energy Storage System is a 12,500kW energy storage project located in Bavaria, Germany.

The electro-chemical battery energy storage project uses lithium-ion as its storage technology. The project was commissioned in 2018.


The Engie-Kraftwerksgruppe Pfreimd – Battery Energy Storage System was developed by Engie Deutschland .

The key applications of the project are frequency regulation, voltage control and grid support services.

Contractors involved

Engie Deutschland and Siemens have delivered the battery energy storage project.

Additional information

The battery will provide primary balancing services, helping to mitigate fluctuations in frequency within 30 seconds of receiving a signal from the grid, aiding the integration of variable renewable energy sources. Siemens will install the system in container units which will include the lithium-ion batteries, the inverters as well as the switch gear and the transformer for grid connection. The scope of delivery also includes the battery management system which will be directly connected to the power station control system.
