Overview of the year
Comprehensive renovation of Silvaplana power plant
June
In June, the groundbreaking ceremony took place for the complete renovation of Silvaplana power plant. Renovation work was successfully completed at several other generation assets.
In June 2025, work began to dismantle the existing water intake at Silvaplana power plant as part of the refurbishment and replace it with a modern, more environmentally friendly system. The transfer from the water intake to the reservoir and part of the pressure pipe were also rebuilt. The turbine set-up at the powerhouse in Silvaplana was replaced with new, more efficient equipment. The protection and control systems were also modernised. “Repower has invested CHF 8.6 million to ensure that the power plant continues to operate safely and reliably in the future,” explains project manager Andriu Maissen. The plant will resume full operation in June 2026.
Refurbishment of Campocologno power plant
The refurbishment of Campocologno power plant was completed back in April 2025. Both spherical valves and the control and secondary technology in the powerhouse were replaced. The Saiento water intake near Monte Scala was also partially renovated. Repower invested a total of around CHF 5 million in the assets. The generation facility on the border with Italy is Repower’s oldest power plant, commissioned in 1906 by the legacy company Forze Motrici Brusio.
Refurbishment of Papierfabrik power plant
The renovation of the Papierfabrik (paper factory) power plant was also successfully completed in 2025. A total of CHF 1.6 million was spent on overhauling components of the facility in Landquart, including the turbine and generator. The entire secondary technology, including low-voltage distribution equipment, was also replaced.
Partial refurbishment of Klosters power plant
A total of CHF 3 million was invested in Klosters power plant. As part of a complete retrofit of the turbine, spherical valve and generator, turbine set-up 2 of the power plant was comprehensively modernised. The second phase involved the complete renewal of the entire secondary technology used to control and monitor the plant. The refurbishment of the other parts of the plant is planned for the coming years.
These substantial investments in plant renovation and refurbishment are in line with Repower’s strategy, which in addition to expanding renewable energy production also entails maintaining existing generation assets.
