The new photovoltaic system at SIGNAL IDUNA PARK, which was developed as part of the sustainability partnership between BVB football club and RWE, is now complete. With 11,132 solar modules and an output of over 5 megawatts (MWp), Germany’s largest stadium now boasts the world's most powerful PV system ever installed on a stadium roof. Going forward, BVB will be able to cover up to half of the stadium's electricity requirements with solar power. This world record has been officially confirmed by the German Record Institute. Compared to the previous power supply, the new solar system will save around 1,700 tonnes of CO₂ per year.
By the beginning of 2026, a battery storage facility with a capacity of 3.7 megawatt hours will also have been built. Once it has been connected to the new PV system, climate-friendly electricity can also be used when the sun is not shining. In April 2024, RWE and BVB installed a new PV system comprising around 200 solar modules on the roof of the BVB Fan World building, located next to the stadium. In summer 2024, RWE and Borussia Dortmund agreed to enter into a six-year partnership. As a 'premium and sustainability partner', RWE will support the renowned club in its ambitious decarbonisation plans.
Markus Krebber, CEO of RWE AG: “We are proud to have set a new record with BVB, one of Germany's most internationally renowned football clubs. Together, we have installed the world's most powerful solar system on the roof of Germany's largest stadium. This is a powerful statement in favour of efficient climate protection, and is the result of the work of two teams that are perfectly aligned in their commitment to sustainability.”
Hans-Joachim Watzke, Chairman of the Management Board BVB: “SIGNAL IDUNA PARK symbolizes our integrated efforts to ensure Borussia Dortmund's future viability. We are delighted that our iconic home can now be associated with a record-breaking flagship project for climate protection.”
Carsten Cramer, Managing Director BVB: “Together with RWE, we have achieved a real milestone in our sustainability partnership – with targeted regional impact and global appeal. This project is a key component of our decarbonization strategy and is the ideal contribution to our commitment and our goal of working with our partners to continuously improve and take on more responsibility.”
