BVB and RWE switch on battery storage at SIGNAL IDUNA PARK

BVB and RWE switch on battery storage at SIGNAL IDUNA PARKThe battery storage system has a power output of 3.7 megawatts, which it can sustain for just over an hour. The photovoltaic system, commissioned in December 2025, comprises 11,132 solar modules and has a capacity of more than 5 megawatts (MWp). Connecting the battery to the new PV system allows the electricity generated to be used even when the sun is not shining. The new photovoltaic system can cover up to 45 percent of BVB's electricity needs at SIGNAL IDUNA PARK. Carsten Cramer, Chairman of the Management Board of Borussia Dortmund: “SIGNAL IDUNA PARK is not only our iconic home, but also a central element of our comprehensive decarbonisation strategy. Together with RWE, we are completing a forward-looking energy concept with this battery storage system, enabling us to make even better use of our solar power. We are delighted that our stadium will continue to stand for greater resource efficiency and innovation.”Dr Markus Krebber, CEO of RWE AG: “With the commissioning of the battery storage system, the combined photovoltaic and battery system at SIGNAL IDUNA PARK is now fully operational. Connecting the two systems allows the solar power generated on site to be used even more flexibly—even when the sun is not shining. Through this project, the experts at BVB and RWE have brought our partnership to life and filled it with energy. A strong foundation for further joint developments.”This article was translated into English by Artificial Intelligence. You can read the original version in 🇩🇪 here.
