About

Founded in 2011, Cadouest is a private headquartered in Prilly, Switzerland specializing in Geothermal, Biomass, Energy Storage.

Cadouest SA was created in 2011 to develop and operate district heating infrastructure in the western Lausanne agglomeration. The company manages a network spanning over 100 km, delivering heat from centralized renewable sources including the Tridel waste incineration facility (220 GWh), wastewater treatment plants, geothermal systems, and recovered heat from air conditioning and exhaust gases. The system has evolved from its origins in 1934 at the Pierre-de-Plan facility. A three-pipe network extension in the Malley zone enables collection of low-temperature returns for reheating via distributed renewable producers, targeting 90% renewable energy composition. The network provides reliable, maintenance-free heating while significantly reducing CO2 emissions and supporting Lausanne's climate action plan. Cadouest is jointly owned by the municipalities of Prilly, Renens, and Lausanne.
