In Janzé, the treatment plant alone represents 25% of the city's energy bill. Faced with this challenge, two solutions were implemented: a photovoltaic park with 4 solar trackers from our partner OKWIND, and the Purecontrol solution to optimize the control of aerators.
Together, these solutions work in synergy to maximize savings and energy efficiency:
- The solar energy produced on site is consumed directly by the critical equipment of the treatment plant, thus reducing dependence on the electrical grid.
- Thanks to Purecontrol, the operation of the aerators is adjusted in real time to coincide with periods of high solar production, maximizing self-consumption.
Since the implementation of these initiatives:
✅ 27% energy autonomy thanks to on-site production
✅ 7% energy savings in one year, obtained thanks to the control of the boosters
