We've been supplying sustainable energy to 1. FC Union Berlin since 2012 – and now we're upping the ante! As the official energy supplier, we not only supply the club with green electricity and green gas, but also focus on social impact: With "Iron Power," we support important social projects together with the "UNION VEREINT. Schulter an Schulter" foundation and strengthen club life beyond sports. Our customers benefit twice: Every contract signing opens up exclusive ticket opportunities for the women's and men's teams' games. In addition, we offer fair rates that are guaranteed to be below the basic supply. And we support regional sports: For every 500th new customer, a donation goes to a partner club in Union Berlin.
