RWE Launches Major Battery Storage Systems to Support Energy Grid Stability in Germany

(IN BRIEF) RWE has launched one of Germany’s largest battery storage systems at its Hamm and Neurath sites, providing 220 MW of capacity to help stabilise the electricity grid. The system contributes to energy market balancing and is integrated into RWE’s broader strategy to support the energy transition. Further developments are planned, particularly at RWE’s Hamm-Uentrop site. The company continues to drive innovation in energy storage globally as part of its commitment to sustainable energy solutions.

(PRESS RELEASE) ESSEN, 15-Feb-2025 — /EuropaWire/ — RWE has successfully commissioned one of Germany’s largest battery storage systems at its Hamm and Neurath sites, with a combined capacity of 220 megawatts (MW). The storage system, which can reach its full capacity within seconds and supply energy at that level for approximately one hour (235 megawatt hours, MWh), plays a crucial role in stabilising the electricity grid. The system is integrated into various energy markets, contributing particularly to grid stability through the balancing energy markets.

The storage system consists of 690 battery cabinets, each housing eight battery modules. The Hamm facility, which was commissioned in December 2024, has a capacity of 140 MW (151 MWh), while the Grevenbroich-Neurath site has a capacity of 80 MW (84 MWh). In addition to the batteries, RWE has also developed the necessary grid infrastructure, including high-voltage transformers that connect the storage systems to the 110-kV grid.

Nikolaus Valerius, CEO of RWE Generation SE, expressed the significance of this achievement, stating, “With the commissioning of the battery storage systems in Neurath and Hamm, we are proud to be operating one of the largest such systems in Germany. Our storage solutions perfectly complement the expansion of renewable energy, which requires large-scale energy storage systems to manage the variability of green energy sources. We already have further storage systems in the planning stages, underscoring RWE’s commitment to providing comprehensive solutions for a range of energy challenges.”

Marc Herter, Lord Mayor of Hamm, highlighted the importance of the new system for the region: “The launch of this significant battery storage facility at the Westfalen power plant site reinforces Hamm’s role as a key energy hub. We are positioning ourselves as a major center for securing green energy supply in the future. With the existing high-performance grid infrastructure and Amprion’s new electricity highway, the region is well-poised for success in the post-coal era. The largest battery storage system in Germany is just the first step in the right direction.”

Klaus Krützen, Lord Mayor of Grevenbroich, emphasized the role of innovation in regional transformation: “As we navigate the structural change in our energy landscape, it is essential to invest in new energy solutions. The battery storage system in Neurath represents a crucial step towards this transformation. The RWE plant not only stabilises the grid but also demonstrates how innovative technologies can support a sustainable and future-ready energy supply. This investment is vital for Grevenbroich and the surrounding Rhenish mining region to become a leading technology and business hub.”

The location selection for the storage facilities was driven by the availability of suitable sites and their proximity to grid connection points, with significant potential for further development, especially in Hamm. RWE plans to expand its battery storage capabilities at the site of its former Westfalen hard-coal power plant in Hamm-Uentrop.

As a leader in the energy transition, RWE develops, builds, and operates battery storage systems globally, including in the U.S., Europe, and Australia. With a total current capacity of approximately 1.2 gigawatts, RWE aims to significantly increase its worldwide battery storage capacity as part of its “Growing Green strategy.”
