Norway’s largest run-of-river hydropower plant, Vamma, will undergo a major modernization: Norwegian utility Hafslund has selected international technology group ANDRITZ to upgrade one of the plant’s turbine-generator units.
This will improve the performance and efficiency of Vamma’s unit 11, reinforcing the plant’s role as a key contributor to Norway’s renewable energy sector.

The project will increase the unit’s capacity by 22%, from 100 MW to 122 MW. It includes dismantling, reassembly, testing and commissioning, as well as model testing and supply of new components.
The scope of supply includes a new oil-free Kaplan runner with a water-filled hub, which will not only improve efficiency but also contribute to the environmental sustainability of the plant. With a diameter of 7,300 mm, it will be one of the largest runners installed in Norway. ANDRITZ will also supply a new turbine governor and stator, which will be assembled on site.

The order, worth a low double-digit million euro amount, was placed in mid-2024. On-site assembly of the new stator is scheduled for the first half of 2026. Commissioning of the fully upgraded Vamma 11 unit is expected in early 2028.
Owned by Hafslund, one of Norway’s leading power producers, Vamma is equipped with 12 turbine-generator units, including ten Francis and two large Kaplan turbines. It has a total installed capacity of 343 MW and supplies an average of 1,580 GWh of electricity per year.
