The contract forms a central part of Tussa Energi’s project to expand capacity at the ageing Tussa hydropower facility in Møre og Romsdal.
The Tussa II plant is designed to utilise the difference in elevation between the Tyssevatn reservoir, positioned roughly 637m above sea level, and the Storfjorden at sea level.
The new build will be equipped with two Pelton turbine units of 75MW each, creating a total installed capacity of 150MW. This represents a notable increase compared to the current facility’s 64MW capacity.
After Tussa II becomes operational, the existing plant will be modernised and retained as supplementary capacity.
Under the contract, Aker Solutions will be responsible for supplying the full range of electromechanical components.
The company will provide inlet pipes, control systems, generators, Pelton turbines, high voltage equipment, cooling and drainage systems, and transformers required for the site.
According to Aker Solutions, the project’s technical solutions have been developed in partnership with Tussa Energi, focusing on improving efficiency, raising capacity, and enhancing the plant’s ability to adapt to future power market requirements.
Aker Solutions power solutions executive vice-president Jo Kjetil Krabbe said: “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.”
The project has involved close early collaboration between Tussa Energi, Norconsult, Aker Solutions and civil works contractor Aurstad Tunnel.
The delivery model has drawn on principles of early supplier participation to shape the scope.
Krabbe said: “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.”
Delivery for the Tussa II project is scheduled for 2030, with the contract to be recorded as order intake in Aker Solutions’ ‘Other’ business segment during Q2 2026.
