Security of supply is particularly important for Bayer 04: "Therefore, we will continue to place the maintenance of our energy systems in the safe hands of EVL, who have always provided us with a reliable energy supply in the past," added Duden. No electricity means no floodlights and no district heating means no undersoil heating. "At the same time, we help Bayer 04 provide energy at the Arena more efficiently and in a more environmentally-friendly manner," said Rolf Menzel, commercial director at EVL. The setting up and certification of the environmental management system in accordance with ISO 50001 standard at Bayer 04 involved support and advice from EVL.
Bayer 04 and Energieversorgung Leverkusen go well together according to Rolf Menzel: "It's hard to imagine the city without the club or without EVL. We both support the area and are committed to Leverkusen." It's not for nothing the club song starts with line 'Zwischen Bayerwerk und Wasserturm' (Between the Bayer works and the Water Tower)," Energieversorgung Leverkusen has supported the club since the early 1980s and is once again a partner in the Sponsors Club this season.
