International, May 2026

In a press release, BKW announced the acquisition of the French energy company Volterres SAS. Volterres SAS operates a network of over 100 solar, wind and hydroelectric power plants and enables the tracking of electricity flows in real time. Volterres supplies more than 2 terawatt hours of electricity annually to companies and public organisations.

The acquisition fits seamlessly into BKW’s existing strategy for France. The company had already previously expanded its activities in the country, including a contract to optimise 200 megawatts of battery capacity. BKW also markets numerous third-party wind, solar and battery projects in France and manages an annual renewable production of over 1 terawatt. With Volterres, BKW now covers the entire energy value chain.

Strategically, the acquisition is an important step within Solutions 2030, according to the press release. With this focus, BKW is concentrating on the Energy Solutions, Power Grid and Infrastructure & Buildings business areas and positioning itself along the entire value chain of the energy transition. The aim is to achieve EBIT (earnings before interest and taxes) of over CHF 1 billion by 2030. France plays a key role in this.

“France is a strategically important market for us. With the integration of Volterres, we are strengthening our position not only there, but in the entire European market and are further developing our portfolio of flexible energy solutions,” said Stefan Sewckow, Executive Vice President Energy Markets.

BKW, based in Bern, is an internationally active energy and infrastructure company. Its range of services extends from engineering and consulting to building technology and the construction and operation of energy and supply grids.
