About The Customer
Azalys is a waste treatment plant located in Carrières-sous-Poissy, France. It is responsible for the management and recovery of urban waste in 23 Yvelines municipalities in the Paris region. The plant is operated by a Suez subsidiary, Helyseo, and belongs to the Valoseine intermunicipal syndicate. Serving an area inhabited by almost 300,000 people, Azalys treats 125,000 metric tons of waste and produces 40 GWh of electricity per year. The plant incinerates non-recyclable waste and transforms the heat into steam, which is then converted by a turbo alternator into energy. Some of this energy is consumed by the site itself, while the rest is sold to the electricity distribution network Enedis.
The Challenge
Azalys, a waste treatment plant in Carrières-sous-Poissy, France, needed to modernize its electrical system while ensuring continuous service for local communities. The plant, which serves an area inhabited by almost 300,000 people, treats 125,000 metric tons of waste and produces 40 GWh of electricity per year. The plant incinerates non-recyclable waste and transforms the heat into steam, which is then converted by a turbo alternator into energy. Some of this energy is consumed by the site itself, while the rest is sold to the electricity distribution network Enedis. The health of the electrical equipment is crucial to the plant’s mission. The modernization process had to be as swift as possible in order not to interrupt the service provided to the local communities.
The Solution
The modernization project involved installing state-of-the-art RM6 and SM6 switchgear in place of FluoKit units, which were later recycled. The new switchgear is equipped with sensors that measure the temperature and humidity in the modules. This information is collected and sent to the EcoStruxure platform, then analyzed and interpreted by Schneider Electric’s Connected Service Hub experts, enabling preventive and predictive maintenance. In addition, substation data, reports, and maintenance recommendations can be consulted in real-time via the mySchneider portal. With timely alerts on equipment issues and support from Schneider Electric field services in fixing them, the facility can minimize the risk of downtime.
Operational Impact
  • System modernization performed in four days, synchronized with the annual production shutdown
  • Implementation of predictive maintenance to ensure the continuity of waste treatment and energy production services
  • Timely alerts on equipment issues and support from Schneider Electric field services in fixing them, the facility can minimize the risk of downtime
Quantitative Benefit
  • The plant treats 125,000 metric tons of waste and produces 40 GWh of electricity per year
  • The modernization process was completed in under four days
