Ingrid, a leading Nordic company specializing in grid technology and energy flexibility, has partnered with Energiequelle GmbH, an international developer, operator, and service provider in renewable energy, to co-develop 200 MW of grid-scale Battery Energy Storage Systems (BESS) across Germany. Under the agreement, Energiequelle will handle project development, while Ingrid will finance, operate, and optimize the storage assets using its proprietary trading and optimization platform. The BESS facilities will be strategically placed in distribution grids to provide flexibility where it is most needed, with most projects expected to reach ready-to-build status in 2026.
Axel Holmberg, CEO of Ingrid, described the partnership as a landmark step for the company in Germany and a key component of its European growth strategy. By 2030, Ingrid aims to optimize more than 1 GW of flexible assets in Germany, addressing challenges in the power grid. Energiequelle’s experience and deep understanding of the market make it an ideal collaborator for this expansion.
Ingrid already operates or is constructing over 450 MW (650 MWh) of battery storage across Scandinavia and has raised more than 300 million euros in capital, establishing itself as a leading developer, owner, and operator in the region. This includes Finland’s largest storage facility at 70 MW (140 MWh). In addition to battery storage, Ingrid provides solutions for renewable energy optimization, green energy supply contracts, and innovative grid services. Alongside its German expansion, the company is also entering the French and Spanish markets.
Michael Raschemann, founder and Managing Director of Energiequelle, highlighted that the partnership combines Ingrid’s expertise in delivering and optimizing large-scale energy storage with Energiequelle’s development capabilities. Together, the companies aim to create long-term societal value, improve grid stability, and advance the energy transition. Founded in 1997, Energiequelle has developed around 2,000 MW of grid infrastructure and connected more than 1,700 MW of wind energy to the grid. The company also develops renewable energy solutions for industrial clients, focusing on photovoltaics and battery storage, and operates in Europe and South Africa.
Deploying battery storage enhances the resilience of power grids, facilitates the integration of renewable energy, and improves economics for renewable energy producers. In Germany, battery storage is becoming a critical component of the energy system, enabling participation in energy and flexibility markets, increasing security of supply, and accelerating electrification in industry and municipalities. These measures help maintain stable and affordable energy prices, strengthen regional competitiveness, and support a faster transition to climate-neutral energy.
