Flexibility Push in the Distribution Grid: Ingrid and Energiequelle Launch 200 MW Storage Programme

Stockholm (Sweden) / Zossen (Germany) – As the energy transition advances, energy storage systems are becoming increasingly important for providing flexibility in the power grid and supporting the integration of renewable energy sources. Against this backdrop, Ingrid and Energiequelle have announced a collaboration on battery energy storage systems (BESS) in Germany.

The goal of the BESS partnership between Energiequelle and Ingrid is to enhance grid stability, integrate renewable energies more efficiently into the system, and accelerate the expansion of flexible infrastructure. As part of the collaboration, Energiequelle is responsible for project development, while Ingrid, a Swedish specialist in flexibility and grid technology, will oversee the financing, operation and optimisation of the storage facilities. To this end, the company uses its own trading and optimisation platform. The BESS projects are intended to be deployed strategically within distribution grids. Most of the installations are expected to be construction-ready by 2026, thereby advancing Germany’s energy transition through flexible storage solutions.

Strategic partnership for battery storage in Germany

Ingrid and Energiequelle are pooling their expertise to jointly develop 200 MW of grid-connected battery storage systems. Through targeted deployment, the facilities are intended to contribute directly to grid stability and reduce bottlenecks in the distribution network.

The battery storage systems will be built specifically in distribution grids – especially at locations where flexibility is already urgently needed today. Most projects are expected to be construction-ready by 2026, forming an important building block of the energy transition.

“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.

Roles are clearly defined: Energiequelle develops the projects, while Ingrid takes charge of financing, operation and optimisation. The storage facilities will be built across Germany precisely where grid operators identify the greatest need for flexibility.

Battery storage as a cornerstone of the energy transition

Battery storage strengthens the electricity grid, facilitates the integration of renewable energies and increases their economic efficiency. At the same time, it enables improved participation in energy and flexibility markets and enhances security of supply by making more controllable, domestically available energy accessible.

“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,” adds Michael Raschemann, owner and managing director of Energiequelle.

Ingrid already operates or is constructing more than 450 MW of battery storage systems, including Finland’s largest storage facility with 70 MW, and has raised over 300 million euros in capital. 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.

The combination of project development, technological operations management and intelligent optimisation via trading platforms helps to ensure stable power flows and enables lower energy prices in the long term. For industry and municipalities, this means reliable electricity supply, accelerated electrification and a measurable contribution to the energy transition.

With their joint 200 MW portfolio, Ingrid and Energiequelle are positioning themselves as key players in Germany’s battery storage market. The partnership strengthens grid stability, promotes a flexible energy supply and supports the efficient use of renewable energy sources.
