District heating network in the lower Wiggertal is getting closer
Primeo Energie and StWZ Energie AG want to establish a company and join forces for a district heating network in the lower Wiggertal. Unlike planned, two regional energy suppliers will not be joining the association for the time being.
The energy companies Primeo Energie from Münchenstein and StWZ Energie AG are in the planning stages for the district heating network Fernwärme Unteres Wiggertal (FUWI). According to a press release, their solution envisages the integration of existing networks.
“The project is an important contribution to the decarbonisation of the heat supply. StWZ and Primeo are convinced that the district heating network in the lower Wiggertal can be realised most effectively if we join forces in a joint company,” Michael Schneider, Managing Director of Primeo Wärme AG, is quoted as saying. The first step will be to expand the district heating network in Oftringen and Zofingen and to integrate the existing district heating networks of both municipalities. Wood combustion in the StWZ energy centres and waste heat from the waste incineration plant (KVA) of Erzo (Entsorgung Region Zofingen) are to be used as climate-neutral heat energy substitutes.
In addition to StWZ Energie AG Zofingen, EW Oftringen AG and EW Rothrist AG were initially involved in the project. Contrary to the plans, the two regional energy suppliers have withdrawn their commitment to join the company for the time being for various reasons. However, according to the press release, both companies are behind the project for CO2-neutral district heating. Participation at a later date has not been ruled out.
The question of a future increase in heat consumption from summer 2027 is also still open. The Oftringen electorate will be asked to vote on the construction of a new waste incineration plant and the additional land required for this in November 2025.
