Voith to upgrade electrical systems at Norway Sima hydropower plant

Voith announced it secured a contract from Statkraft Energi AS to modernize electrical power and automation systems at the Sima hydropower plant located in Eidfjord, Norway. Commissioned in 1980, the facility is recognized as Norway's second-largest hydropower plant. The extensive overhaul aims to extend the operating life of the station, maintain long-term availability, and reduce failures and unplanned downtime across the critical renewable energy asset.

Statkraft stands as Norway's and Europe's largest producer of renewable energy. Its expansive hydropower plants account for approximately one-third of Norway's total electricity output. Beyond hydropower, the group produces wind power, solar power, and gas-fired power.

The engineering undertaking requires delicate coordination to avoid costly production interruptions. Rather than shutting down production entirely, technicians will integrate new components into the existing infrastructure in carefully managed phases. This step-by-step replacement methodology is designed to limit the risk of unscheduled downtime and maintain continuous power output during the transition.

Voith's comprehensive scope of supply covers control and protection systems, software developed and maintained by in-house specialists, medium-voltage components, associated cabling, and balance-of-plant equipment including new AC/DC systems. As a global technology company founded in 1867, Voith operates through its Voith Hydro group division as a full-line supplier equipping large and small hydropower plants worldwide.

Both corporate partners emphasized the importance of their long-standing relationship in executing the project. According to the companies, Voith has collaborated with Statkraft for more than twenty years, building a foundation of in-depth knowledge regarding technical requirements.

"We have partnered with Statkraft for more than twenty years, which gives us in-depth knowledge of their requirements and a clear perspective on the complexities involved in the modernization of the Sima plant. By taking full responsibility for this project, we are able to streamline processes, minimize risks, and ensure a smooth and rewarding experience for everyone involved. We are proud to support Statkraft’s commitment to ensuring reliable hydropower generation for the long term."

Statkraft power plant manager Kristin Lindvik also highlighted the operational priorities guiding the refurbishment effort.

"The Sima hydropower plant is an impressive example of engineering excellence that has been generating electricity since 1980. Our goal is to extend its lifetime in the most sustainable and efficient manner possible. It is crucial that modernizing of such a critical plant is performed safely and efficiently with minimal disruption to our operations and production of renewable power."

The modernization project builds on the ongoing investments made by Statkraft in its broader hydropower fleet to support reliable renewable generation for the future. As the phased refit progresses, the supplier and operator will continue working together to integrate the new control systems while keeping the plant operational.
