As the largest distribution system operator in Switzerland, BKW maintains an electricity grid of around 22,000 kilometres, and provides energy to over one million people and companies in its supply area. As part of its “Solutions 2030” strategy, BKW is planning to invest around CHF 1 billion in the maintenance, digitalisation and expansion of the distribution system between 2025 and 2030. The distribution system is a key element of the energy transition, as it connects producers and consumers, making an important contribution to the reliability of supply.

With its fourth green bond, BKW is securing attractive long-term financing conditions and fitting the bond perfectly into the existing maturity profile. In issuing the fixed-interest bond, BKW was able to take advantage of high investor demand, which reflects confidence in BKW and its strategy.

The settlement of the bond will take place on 27 April 2026. The transaction was led by BNP PARIBAS SA, Deutsche Bank AG and Raiffeisen Schweiz Genossenschaft. The bond will be listed on the SIX Swiss Exchange.
