Actively shaping the energy future
This is what the innovative energy supplier EWS Energie AG wants and is continuously working on making energy sustainable. Innovative solutions such as the solar folding roof are helping to bring about the energy revolution. The new solar folding roof over the Reinach wastewater treatment plant is in operation since May 2021. Those responsible at the Aargau-based energy supplier EWS Energie AG were inspired by the pilot project, the first solar folding roof over the Chur WWTP, which was inaugurated in 2017.
Over an area of 4,400 square metres, 1,440 solar panels provide electricity production above the sewage treatment basins of the Reinach WWTP. It thus has the largest installed span to date. At 450,000 kWh per year, the folding solar roof produces about a third of the WWTP’s total electricity needs, which is equivalent to about 100 households.
