  • Climate-friendly heat supply for Zofingen and Oftringen

    Climate-friendly heat supply for Zofingen and Oftringen

    StWZ Energie AG and Primeo Energie want to jointly create a sustainable district heating supply in the lower Wiggertal valley. To this end, the energy service providers have founded the joint company Fernwärme Unteres Wiggertal AG (FUWI) as of 19 September 2025. The aim is to combine “infrastructure, customer proximity and energy expertise” in order to further develop the heat supply in a climate-friendly way.

    The new network is to be operated using waste heat from the erzo-KVA waste incineration plant and from existing decentralised StWZ energy centres. Existing heating networks from StWZ in Zofingen and Primeo Energie in Oftringen are to be integrated.

    The first households are to be supplied with low-CO2 heat energy from the new network from summer 2027. Two phases are planned for the expansion. Phase one is to begin in 2026 from the erzo-KVA waste incineration plant and run towards Oftringen Süd and Zofingen. The second phase will follow in 2030 at the earliest and will depend on the planned new construction of the waste incineration plant. This will require the consent of the people of Oftringen for the zoning of a required piece of land. If both construction phases go into operation, 10,000 households could be supplied with heat and 30,000 tonnes of CO2 could be saved.

    Michael Schneider, Managing Director of Primeo Wärme AG, sees the energy revolution as a heating revolution. This step lays a “foundation stone for a long-term sustainable heat supply in the lower Wiggertal”. “By combining regional energy sources with modern technology, we are reducing CO2 emissions in a targeted manner and expanding the supply of reliable, decarbonised heat,” Paul Marbach, Managing Director of StWZ Energie AG, is quoted as saying.

  • Alliances to supply 45 per cent of the heat in Winterthur

    Alliances to supply 45 per cent of the heat in Winterthur

    The city of Winterthur can cover 45 per cent of the city’s heating needs with public heating networks. Energy from the municipal utility’s waste incineration plant could cover 33 per cent of the city’s heating needs, the city writes in a statement. Wood, biogas and waste heat utilisation could provide another 10 per cent. The new Schützenwiese energy centre could cover another 2 per cent by using groundwater heat.

    About two-thirds of the necessary municipal heating networks have already been realised. Further investments are needed for the remaining third. For example, the electorate must approve the building loan for the replacement of incineration line 2 of the waste incineration plant. From 2028, this line will generate waste heat energy from the flue gas purification plant. In addition, around 300 million Swiss francs must be invested in the expansion of the city’s heating networks. For this purpose, a credit bill is to be prepared by the end of 2024, which will also be voted on by the electorate. These heating networks are to supply areas with high energy density with heat.

    The city council estimates that around 55 per cent of the city’s heating needs will have to be covered by private solutions. Another study will examine how areas with lower energy density can be developed economically and ecologically.

  • Drilling for the Ennetsee heating network begins

    Drilling for the Ennetsee heating network begins

    According to a press release from WWZ , the construction of the 6.5 kilometer long heat transport pipeline from Perlen to Rotkreuz is in the starting blocks. It is part of the Ennetsee heating network. A challenge of this construction phase is the trenchless crossing under the Reuss and the A14 motorway. To this end, WWZ is starting these days between the sports field of the Root LU sports club and the Rütilöli area in Inwil LU with two pilot drillings for protective plastic pipes. The official start of construction is at the end of March, beginning of April.

    The official start of construction of this heat transport pipeline from the Renergia waste incineration plant in Perlen to Rotkreuz is planned for this spring. The district heating pipes would then also be pulled into the protective pipes under the A14 motorway. After completion of the major project, the region should save around 12,000 tons of CO2 annually.

  • Limeco does not need to lower the price of municipal waste immediately

    Limeco does not need to lower the price of municipal waste immediately

    Limeco has achieved an interim success in the dispute with the price watchdog. As the company reports , the Federal Administrative Court has granted suspensive effect to the complaint made by the operator of the waste incineration plant in Dietikon. The St.Gallen judges are thus opposing the price watchdog, who wanted to deny the complaint this suspensive effect.

    In addition, as requested by Limeco, the judges also require the specialist authorities to be involved in the decision. These are the Office for Waste, Water, Energy and Air of the Canton of Zurich , the Federal Office for the Environment and the Federal Competition Commission .

    In an order in September , the price watchdog stated that “Limeco's price for the incineration of municipal waste was abusively too high”. He wanted to oblige Limeco as early as January 1, 2021, to lower the price that the municipalities would have to pay for the consignment to 102 francs per ton.

    Limeco then filed a complaint with the Federal Administrative Court in October. Limeco argued that the transfer prices corresponded to the requirements of the federal government and the canton of Zurich. They are appropriate and are necessary for “sustainable, cost-covering and polluter-friendly disposal of municipal waste”. The price watchdog made some false assumptions.

    The price monitor can comment on Limeco's complaint until mid-February.
