Bern-Wabern heating network promotes energy transition and CO2 reduction

Energy supplier ewb and the municipality of Köniz want to use surplus water from the Schönau pumping station to generate renewable heat for 5,000 households. To this end, they are building the Bern-Wabern heating network.
The energy company Energie Wasser Bern(ewb) and the municipality of Köniz want to make a contribution to reducing CO2 emissions and achieving the climate policy goals of Köniz and Bern with the Bern-Wabern energy network, according to a press release.
The ewb Board of Directors decided to build the Bern-Wabern heating network on March 7, 2025, based on the “great interest” of the population as determined by a survey. Construction of the production facilities is scheduled to start in 2027. The first heat supply is expected from 2028.
Specifically, the heat production concept envisages using the energy from surplus water from the Schönau pumping station for thermal use. The production facilities will be installed in the existing heating center of the Morillon residential complex on Bondelistrasse.
With the cooperation agreement that has now been signed, the heating and cooling supply in Wabern will be the responsibility of ewb, which is also responsible for the operational and financial responsibility for the construction.
The heating network could help to promote the energy transition and climate protection. The sustainable energy project will create a replacement for many oil and gas heating systems in Wabern and the neighboring districts of Bern. “In densely built-up areas, a heating network is often the only solution for heating buildings with renewable energy in a CO2-free and economical way,” says Hansueli Pestalozzi, a local councillor in Köniz.
