District heating project in Bern utilises the River Aare as an energy source
Energie Wasser Bern (ewb) is examining the establishment of a heating network in the north-east of Bern. Ewb also wants to utilise the heat from the River Aare as an energy source. Water is to be drawn from the river at Engehalde for this purpose. An application to this effect has already been submitted.
Energie Wasser Bern wants to supply the north-east of Bern with climate-friendly heat. To this end, the Bernese energy supplier is planning to build a corresponding heat production infrastructure, ewb announced in a press release. One of the sources of heat will be the water from the River Aare.
Specifically, ewb wants to draw water from the Aare on the western bank at Engehalde and channel it into an existing cavern. Heat is to be extracted from the water here, which will then be transported to a new Aare Wyler energy centre to be built on the eastern side of the river. Properties in neighbourhoods adjacent to the energy centre could then be heated with district heating from the energy centre’s heat pumps. Ewb is also considering setting up a second, smaller Aare Engehalde energy centre on the west side of the river. It could supply the Tiefenau area with district heating.
The company has already submitted a licence application to the Office for Water and Waste of the Canton of Bern for the construction of a catchment structure and the extraction and return of water from the Aare, explains ewb. The company expects a decision in spring 2026. In the meantime, a precise location for the planned Aare Wyler energy centre is to be found.
