Green electricity and weather station – energy efficiency at Bayer 04

Bayer 04 Leverkusen is aware of its position as a social role model and of the increasing demands in the use of energy resources – independent of the additional demands in this area that have arisen in 2022. Over the past six years, the club has been able to reduce overall energy consumption by more than 30 per cent through targeted technical improvements. And in future the club will examine all options that promise a positive effect on the energy use at the football business.

Bayer04.de has put together a list of current and significant measures in and around the BayArena.

lighting at the BayArena

From this season, Bayer 04 has a partner for state-of-the-art energy-saving lighting in the company ‘Ledvance’. Swapping the lighting at the BayArena and in a lot of other buildings on the site for LED lighting has had a positive effect on energy use. In addition, the operational life of many facilities has been improved many times over.

external lighting at the BayArena

There is also targeted use of lighting in the external areas at the stadium: If there are no events at the BayArena, only footpath lighting is in operation during the evening and is completely switched off from midnight. Only in exceptional cases, such as darkness in winter, the lighting is switched on again at six in the morning to ensure traffic safety. The two big signs at the BayArena including the Bayer Cross on the roof of the stadium will be completely switched off until further notice. Lighting is principally only used when that is required for matches or security.

ELECTRICITY CONSUMPTION

Bayer 04 has only used certified green electricity since 2015. The club reacted early to the massive increase in energy prices and purchased supplies for the next two years in good time.

SOLAR PANELS

The roofs of the garages and storage buildings in and around the BayArena have long provided a storage facility for energy thanks to state-of-the-art solar panels. Solar energy also powers the newly introduced electric mowers used by the grounds staff. At the moment, the roof of the BayArena cannot be used to site solar panels due to structural restrictions.

HEATING

Bayer 04 believes in ecological sustainability with heating and that starts with the most important place in football: the pitch. In order to guarantee trouble-free training and matches over the whole year undersoil heating at the pitches in and around the BayArena is indispensable (and also prescribed by the German Football League (DFL)). To ensure the best possible use of energy, the undersoil heating is linked to a weather station and the prevailing conditions. This approach has achieved a two thirds reduction in the use of heating energy. In addition, lava stone grit under the turf at the stadium also saves additional energy.

WATER USE

In addition to undersoil heating, the watering of pictures is of crucial significance in ensuring the required match and training conditions. Bayer 04 also follows a considered and rational use of resources in this area and only waters the pitches with water from the club water storage facility rather than valuable drinking water. The staff at Bayer 04 have recently been supplied with access to drinking water with a system that avoids the use (and transport) of plastic bottles.

WASTE MANAGEMENT

Recycling is an important component of modern waste management. Accordingly, Bayer 04 has recently invested in two composting facilities that converts grass cuttings into compost that is rich in nutrients. Food waste from all events at the BayArena is also recycled in this way.

E-MOBILITY

Four charging stations for electric cars were installed at the south entrance to the stadium in 2021 and plans are underway to introduce others.

Season review 2025/26, part II: Highs and lows of an eventful season

Lying third in the Bundesliga, the Werkself made a faltering start in 2026 after the winter break, but gradually rediscovered winning ways and, as in the previous campaign, were among the top 16 in Europe and the top four in the DFB Pokal. In the Bundesliga, the Werkself also remained in the race for Champions League qualification right to the end. However, because setbacks repeatedly crept into the Werkself's performances between good displays and crucial games, it was not quite enough to secure a UCL spot in the end. A season with many ups and downs brought sixth place and qualification for the UEFA Europa League. Part II of the review of the 2025/26 season.

2025/26 season review, part I: Upheaval, change, euphoria

Following the final match of the 2025/26 season, the prevailing feeling was naturally one of disappointment after missing out on qualification for the Champions League. The Werkself finished the Bundesliga in sixth place, meaning they'll start the 2026/27 campaign in the Europa League. "But to talk negatively about everything now because of that would be wrong," stressed captain Robert Andrich following the final game, knowing that the past year at Bayer 04 was marked, more than almost any other, by the start of a new era and the courage to change – and in particular, the belief in a positive direction. Everyone was aware this process would need time. The first part of the 2025/26 season review.
