Ingrid and Energiequelle Announce Strategic Partnership to Deploy Battery Energy Storage Systems Across Germany
Together, the companies aim to bring 200 MW
Stockholm/Zossen, 04.03.2026 (PresseBox) - Ingrid, the leading Nordic flexibility and grid-tech company, and Energiequelle GmbH, a leading international renewables developer, operator and service provider, have signed a co-development agreement to deliver 200 MW of grid-scale Battery Energy Storage Systems (BESS) throughout Germany. Under the partnership, Energiequelle will lead project development, while Ingrid will finance, operate, and optimize the assets using its in-house trading and optimization platform. The BESS projects will be strategically deployed in distribution grids across Germany, targeting locations where flexibility is most needed. Most projects are expected to reach ready-to-build status in 2026.
“This is a landmark partnership for Ingrid in Germany and an important step in our European growth strategy. By 2030, we aim to optimize more than 1 GW of flexible assets in Germany and thereby address challenges in the power grid. Energiequelle’s proven track record and deep market knowledge make the company an ideal partner for us on this journey,” says Axel Holmberg, CEO of Ingrid.
Ingrid already operates or is constructing more than 450 MW (650 MWh) of battery storage and has raised over 300 million euros in capital, making it the leading developer, owner and optimizer in Scandinavia. This includes Finland’s largest storage facility at 70 MW (140 MWh). In addition to energy storage and the optimization of BESS and renewable energy, Ingrid also offers structures for green energy supply and offtake as well as innovative grid services. Alongside its expansion into the German market, the company is also entering France and Spain.
“Our mission is to advance the energy transition with innovative, reliable, and flexible solutions. Ingrid’s expertise in delivering and optimizing large-scale energy storage is a strong complement to our development capabilities. Together, we can create long-term value for society and expand grid stability as part of the energy transition,” says Michael Raschemann, founder and Managing Director of Energiequelle.
Since its founding in 1997, Energiequelle has built around 2,000 MW of grid infrastructure and connected more than 1,700 MW of wind energy to the grid. In addition, Energiequelle develops innovative energy supply solutions for industrial companies, particularly using photovoltaics and battery storage. The company operates in Europe and South Africa.
The deployment of battery storage increases the resilience of power grids, supports the integration of renewable energy, and improves the economics for renewable energy producers. As a result, battery storage is becoming a key pillar of the German energy system on the path to climate neutrality. It also enables better participation in energy and flexibility markets while simultaneously increasing security of supply, as more domestic and dispatchable power becomes available. Electrification in industry and municipalities is also accelerated. Ultimately, these measures lead to stable and affordable energy prices, strengthen regional competitiveness, and support a faster energy transition.
