District heating from wastewater to decarbonise the municipality
The energy company CKW is awarded the contract for the project planning of the planned district heating network in Richterswil. CKW is now aiming for a long-term partnership to decarbonise the municipality. The next steps will be announced in autumn 2025.
The energy company CKW, part of the Axpo Group, has been awarded the contract for the prequalification of the planned district heating network in Richterswil. With the district heating network, which is central to the municipality’s energy and climate concept, the energy company wants to launch a long-term partnership for decarbonisation, according to a press release.
The energy network will mainly be operated using waste heat from the Richterswil wastewater treatment plant (WWTP). Additional heat production for peak load and security coverage will be evaluated in the future. The aim is for commercial enterprises and residents to benefit from an economically attractive offer. “We are delighted to have been awarded the contract and are convinced that we can plan an economical and sustainable heat supply in Richterswil,” Angela Krainer, Head of Energy at CKW, is quoted as saying in the press release.
In future, CKW will be responsible for the entire project planning of the heat network. The collaboration between the municipality and the company is to be concretised in the summer and the next project steps are to be taken in autumn 2025.
