Overview of the year
Great celebrations mark the reopening of Robbia power plant
August
In August, Repower reached a milestone when it completed the total modernisation of Robbia power plant. After four years of construction work, the facility is once again operating at full capacity.
The comprehensive renovation of Robbia power plant is the largest renewal investment in the history of Repower. The opening ceremonies took place on 24 and 25 August 2024. Over 700 visitors took the opportunity to tour the modernised facility.
The complete renovation of Robbia power plant began in the summer of 2020 and included the full modernisation of the plant from the water catchments to the turbines. The first turbine set-up was successfully synchronised with the power grid in December 2023. All three turbine set-ups have been in full operation since June 2024. The modernisation has increased the volume of electricity generated by the Robbia plant by some 10 per cent to around 120 GWh.
Repower took great care to ensure safety during construction. Even though there were up to 100 people working at the various construction sites at any given time, not a single serious accident occurred during the four years of construction.
Carmelia Maissen, member of the Graubünden government and head of the Department of Infrastructure, Energy and Mobility, was among those attending the inauguration. In her speech, she emphasised the important role of Repower in the Graubünden energy industry and the great significance of hydropower for the canton.
Roland Leuenberger, CEO of Repower: “The total modernisation of the Robbia plant represents an important contribution to hydropower and the security of supply in Graubünden. Wherever possible, we took regional businesses into account during construction. Around CHF 66 million of the money invested flowed into the regional economy.”
