“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.
About Ingrid
The future runs on electricity, but the system behind it is stuck in the past. Ingrid builds the infrastructure and software that make the power grid more intelligent, helping accelerate a resilient and clean energy transition. Our solutions include grid-scale energy storage, advanced optimisation for battery systems and renewable assets, green energy supply and offtake structures, and innovative grid services. By increasing grid flexibility, stabilising power flows and improving the utilisation of existing infrastructure, we help reduce grid bottlenecks, support the integration of new renewable generation and contribute to more stable, lower electricity prices. Founded in 2022 and headquartered in Stockholm, Ingrid has 70+ employees, operates across the Nordics and is expanding throughout Europe. As of Q4 2025, we have more than 650 MWh of storage in operation or under construction, and over 250 MWh of assets optimised through our in-house trading and optimisation platform.
