Aker Solutions has secured a sizeable contract from Tussa Energi to supply electromechanical equipment for the Tussa II hydropower plant in the Volda region of western Norway.
The contract forms part of Tussa Energi’s expansion project, which will increase installed capacity at the site to 150MW from the existing 64MW. The current Tussa power plant, which has been operating for more than 60 years, will be modernised after the new facility enters service and retained as additional capacity.
“Hydropower is the backbone of the Norwegian power system and will remain important in the years ahead. Together with Tussa Energi we have developed technical solutions that improve efficiency, increase capacity, and enable better adaptation to future power markets,” said Jo Kjetil Krabbe, Executive Vice President, Power Solutions at Aker Solutions.
The new plant will use the elevation difference between the Tyssevatn reservoir, around 637m above sea level, and the Storfjorden at sea level. It will be equipped with two 75MW Pelton turbine units.
Under the contract, Aker Solutions will supply inlet pipes, Pelton turbines and generators, control systems, cooling and drainage systems, high-voltage equipment and transformers.
The project has been developed through collaboration between Tussa Energi, Aker Solutions, Norconsult and local civil works contractor Aurstad Tunnel using an alliance-inspired delivery model with early supplier involvement.
Work on the project has started, with delivery planned for 2030.
“We believe Tussa Energi’s forward-leaning and collaborative approach during the early phases of the project will contribute significantly to its success. We hope this model of early supplier engagement will set a new benchmark for the hydropower industry,” said Jo Kjetil Krabbe.
Aker Solutions said the contract will be booked as order intake in the company’s “Other” segment in the second quarter of 2026.
