WWZ announces significant increase in turnover

Thanks to a strong business performance, Zug's largest energy supplier plans to pay out a dividend again.
 

The Zug-based energy supplier WWZ (Wasserwerk Zug) announced on Wednesday that the expansion of the heating networks (Wärmeverbunde) is progressing according to plan, and that demand has remained high in 2025. Sales rose by 29%, resulting in a significant increase in revenue.

At the same time, the operating result for this segment improved significantly compared with the previous year. According to WWZ, this confirms the growth strategy it has pursued. The company plans to publish its detailed business figures on the 8th April 2026.

According to the company, it also reached an important milestone in the telecommunications business. The WWZ has successfully completed the switchover of around 120,000 products for 45,000 customers to its own products. At the same time, the new ‘Blizz’ brand has been launched. With the completion of the switchover, the foundation has been laid for significantly higher profitability in the coming years, according to WWZ.

Closure of a nuclear power plant weighs heavily on results
In terms of the WWZ Group's business performance, the electricity segment saw stable sales in the basic supply (Grundversorgung), despite increasing own consumption. In the previous year, WWZ still benefited from a settlement with Alpiq, and one-off effects amounting to CHF 13.8 million were eliminated in the electricity segment in the reporting year.

The shutdown of the Gösgen nuclear power plant, which has been out of operation since May 2025, also had a negative impact.

The ‘Other’ segment performed well, growing and outperforming the results of the previous year. Overall, the WWZ Group achieved a stable operating result, adjusted for one-off effects from the previous year. Net financial assets remained positive despite continued high growth investments, the WWZ further reports.

Due to the solid financial situation and intact business prospects, the Board of Directors intends to once again propose a dividend of CHF 40 per share to the Annual General Meeting, the WWZ concludes.
