Köniz tests power supply with 100 per cent renewable energy

The energy supplier BKW is testing new solutions for supplying electricity from renewable energies. To this end, the Bern-based company is conducting a pilot project in the Mittelhäusern district of the municipality of Köniz. The project will provide real-time data over three years.

Bern/Köniz BE, October 2025

The Bernese energy supplier BKW is testing new solutions for supplying electricity from renewable energies. According to a press release, a three-year pilot project will provide real-time data on electricity demand and consumption in the Mittelhäusern district of the municipality of Köniz.

The choice of test area was the result of a feasibility study commissioned by the municipality of Köniz. The test focussed on supplying electricity to the 950 residents of the municipality. In the contiguous supply area, the electricity supply is to be realised using renewable energies. After the test phase, all energy customers will have the opportunity to obtain 100 per cent renewable energy, which is more environmentally friendly and cheaper than before, according to the press release.

Mittelhäusern could become the first Swiss village to cover its entire energy requirements, i.e. electricity, heat, mobility and processes, from renewable sources, according to BKW. However, a separate follow-up project is planned for the areas of heat and mobility.

The central aim of the study is to provide BKW Power Grid with data and experience with real-time sensor and actuator technology in a practical experiment. The aim is to ensure a stable and efficient power supply at all times. As a result, the understanding of an intelligent overall electrical system (smart grid) should be improved.
