ANDRITZ to Boost Capacity of Vamma Hydropower Unit

ANDRITZ has received an order to upgrade the Vamma 11 hydropower unit, increasing its capacity from 100 MW to 122 MW. The project will involve dismantling, reassembly, testing, and commissioning, along with model testing and the supply of new components. A key element of the upgrade is the installation of a new oil-free Kaplan runner with a water-filled hub, which aims to improve efficiency and contribute to the plant's environmental sustainability.

The new Kaplan runner, measuring 7,300 mm in diameter, will be one of the largest installed in Norway. In addition, ANDRITZ will provide a new turbine governor and stator, which will be assembled on site. The project, valued in the low double-digit million euro range, was commissioned in mid-2024, with the stator assembly planned for the first half of 2026 and full commissioning expected by early 2028.

“This project is a milestone in our close partnership with Hafslund. By upgrading the Vamma 11 unit, we’re not only boosting its efficiency and capacity but also extending its operating life to ensure that it continues to support the country's ambitious renewable energy targets,” said Kjetil Toverud, Managing Director of ANDRITZ Hydropower in Norway.
