Ingrid and Energiequelle GmbH have entered into a partnership to develop grid-connected battery energy storage systems with a total capacity of 200 megawatts in Germany.
Energiequelle will lead project development while Ingrid will handle financing, operating and optimising the assets using its internal trading and optimisation platform, according to the companies.
The projects will be deployed in distribution grids across Germany at locations where flexibility is most needed and most are expected to be ready for construction in 2026.
“This is a groundbreaking partnership for Ingrid in Germany and an important step in our European growth strategy,” Ingrid chief executive officer Axel Holmberg said.
“By 2030, we want to optimize more than 1 GW of flexible plants in Germany and thus overcome the challenges in the power grid,” Holmberg said.
Ingrid already operates or builds over 450 MW of battery storage and has raised more than 300 million euros in capital, the company said.
These include Finland’s largest storage facility with 70 MW, the company said.
Ingrid added that it is expanding into France and Spain in addition to its entry into Germany.
“Our task is to advance the energy transition with innovative, reliable and flexible solutions,” Energiequelle owner and managing director Michael Raschemann said.
Energiequelle has built about 2,000 MW of grid infrastructure and connected over 1,700 MW of wind energy to the grid since its founding in 1997.
The company also develops supply solutions for industrial customers, particularly photovoltaics and battery storage, and is active in Europe and South Africa.
The companies said battery storage supports renewable integration, strengthens the power grid and increases economic efficiency.
They added that storage improves participation in energy and flexibility markets, enhances security of supply and accelerates electrification in industry and municipalities.
