Aker Solutions has been awarded a sizeable contract by Tussa Energi to supply all electromechanical equipment for the Tussa II hydropower plant, a 150 MW facility that will significantly expand generating capacity at the existing Tussa hydropower complex in western Norway.

The contract, valued between NOK 500 million and NOK 1.5 billion under Aker Solutions' classification, covers the delivery of inlet pipes, two 75 MW Pelton turbines, generators, control systems, cooling and drainage systems, high-voltage equipment, and transformers. The order will be recorded in the company's "Other" segment during the second quarter of 2026.

The Tussa II project is designed to harness the elevation drop between the Tyssevatn reservoir, located about 637 meters above sea level, and Storfjorden, increasing installed capacity from the current 64 MW to 150 MW. Once the new plant enters service, the existing hydropower station—now more than six decades old—will be modernized and retained as supplementary generating capacity.

Project delivery is scheduled for 2030.

Aker Solutions said the project has been developed through early collaboration with Tussa Energi, engineering consultant Norconsult, and civil works contractor Aurstad Tunnel using an alliance-inspired delivery model that brings suppliers into the project during its early design stages.

The company said the approach helped develop technical solutions aimed at improving plant efficiency, increasing generation capacity, and enhancing operational flexibility to respond to evolving electricity market conditions.

Norway generates the vast majority of its electricity from hydropower, making upgrades and expansions of existing hydro assets a central part of the country's strategy to strengthen renewable electricity supply without building entirely new reservoirs. Modernization projects such as Tussa II are intended to boost output and improve grid flexibility as electricity demand grows from industrial electrification and the broader energy transition.
