ANDRITZ's “from water-to-wire” scope covers a new Kaplan turbine, a generator, and the complete replacement of the automation and electrical power systems. The project will increase the plant's installed capacity by 6 MW through increased discharge capacity, bringing the total to 28.5 MW. The model test of the new runner will be conducted at ANDRITZ's hydraulic laboratory in Tampere, Finland. The generator will be designed and manufactured in Weiz, Austria. Commissioning is scheduled for 2028.
As Norway continues to expand variable renewable energy generation, the flexibility of hydropower plants becomes increasingly important for grid stability. This makes modernization projects such as the one at Strandfossen an important part of the country’s energy transition.
The Strandfossen plant was commissioned in 1979 with equipment from KMW, whose hydropower business is today part of ANDRITZ. The plant currently generates 154 GWh of electricity annually, equivalent to the demand of around 10,000 Norwegian households. Following the upgrade, its annual generation is expected to increase to 168.5 GWh, enough to supply around 1,000 additional households.
This project builds on the ongoing partnership between Hafslund and ANDRITZ. ANDRITZ is currently also rehabilitating Hafslund’s Vamma plant, the largest run-of-river plant in Norway.
