When Hafslund Kraft (formerly Hafslund Eco) looked for solutions to increase power production around Osensjøen, they chose to collaborate with Stryvo. The result was a series of successful deliveries, increasing the production of renewable energy by 20 GWh.
Background
Hafslund Kraft is Hafslund’s hydropower business and accounts for about 13 percent of Norway’s total hydropower production. The project around Osensjøen supported national goals to optimize the utilization of already existing power plants. Hafslund Kraft has collaborated with Stryvo on several occasions, and chose Stryvo as the supplier of several crucial components for the upgrade around Osensjøen.
The Solution
The project, completed in 2022, transfers water from Øvre Flisa (in Elverum and Trysil municipalities) and Østre Æra (in Åmot municipality) to Osensjøen, to increase the production of renewable energy by 20 GWh, mainly at the Osa power plant in Åmot. The project supports national objectives to optimize the use of existing regulations and power plants.
Stryvo delivered the following equipment for the various water flows:
Transfer from Østre Æra to Osa Power Plant:
- Hydraulic gate valve
- Hydraulic system
- Tyrolean weir (trash rack)
- Minimum flow pipe with electric valve
- Bottom outlet pipe with valve
- Ventilation pipe
Transfer from Øvre Flisa to Osensjøen:
- Sluice gate
- Cone in the upper valve chamber
- Pipe rupture valve
- Pipes and diffuser in the lower valve chamber
- Control valve
- Ventilation pipe
- Hydraulic system
- Minimum Flow Håsjøen
- Electric hoists
Everything was designed and produced to meet strict requirements for functionality and durability. Each phase of the project, from planning to installation, was carefully coordinated with Hafslund Kraft to ensure everything ran smoothly.
Results
All equipment delivered by Stryvo has functioned flawlessly, contributing to stable and secure renewable energy production. Feedback from Hafslund Kraft has been positive, especially regarding Stryvo's ability to deliver on time and maintain open and effective communication throughout the process.
