European energy firms Ingrid and Energiequelle GmbH are partnering to develop 200 megawatts of grid-connected battery energy storage systems (BESS) across Germany. The projects will be deployed within distribution networks to provide flexibility and grid stability.

Under the agreement, Energiequelle will manage project development, while Stockholm-based Ingrid will handle financing, operation, and system optimisation. Ingrid will employ its internal trading platform to manage the assets. Most of the projects are expected to reach the construction phase by the end of 2026.

Total planned capacity of the programme will be 200 MW of grid-connected BESS, with a target market of German distribution networks requiring greater grid flexibility. Ingrid’s current portfolio is over 450 MW of capacity in operation or under construction, while Energiequelle’s track record includes 2,000 MW of grid infrastructure and 1,700 MW of wind energy connected

Axel Holmberg, CEO of Ingrid, said the company aims to optimise more than 1 GW of flexible energy storage in Germany by 2030. The partnership follows Ingrid’s expansion into France and Spain, supported by more than €300 million in raised capital.

Michael Raschemann, CEO of Energiequelle, stated that the use of large-scale storage is a necessary component for the integration of renewable energies into the German grid. Energiequelle, founded in 1997, operates across Europe and South Africa, developing supply solutions for industrial clients.
