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. The partnership was announced on November 26, 2025, from Stockholm and Zossen.

Partnership Structure and Responsibilities

Under the partnership agreement, 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 across Germany's distribution grids, targeting locations where flexibility is most needed. Most projects are expected to reach ready-to-build status in 2026.

Axel Holmberg, CEO of Ingrid, described this as "a landmark partnership for Ingrid in Germany and an important step in our European growth strategy." He stated that by 2030, the company aims to optimize more than 1 GW of flexible assets in Germany to address challenges in the power grid. Holmberg noted that Energiequelle's proven track record and deep market knowledge make the company an ideal partner for this journey.

Company Backgrounds and Capabilities

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, with a capacity of 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.

Energiequelle has built around 2,000 MW of grid infrastructure and connected more than 1,700 MW of wind energy to the grid since its founding in 1997. The company develops innovative energy supply solutions for industrial companies, particularly using photovoltaics and battery storage, and operates in Europe and South Africa.

Michael Raschemann, founder and Managing Director of Energiequelle, stated that the company's mission is to advance the energy transition with innovative, reliable, and flexible solutions. He described Ingrid's expertise in delivering and optimizing large-scale energy storage as a strong complement to their development capabilities, noting that, together, they can create long-term value for society and enhance grid stability as part of the energy transition.

Strategic Impact on German Energy System

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. Battery storage is becoming a key pillar of the German energy system on the path to climate neutrality. It enables better participation in energy and flexibility markets while simultaneously increasing security of supply, as more domestic and dispatchable power becomes available.

The partnership aims to accelerate electrification in industry and municipalities. These measures are expected to lead to stable, affordable energy prices, strengthen regional competitiveness, and accelerate the energy transition.
