Power play for wild salmon
Output power is an approach to generating electricity from hydropower that involves higher electricity production over short periods. However, no one knows how this approach will affect the salmon population in a river over time. Researchers at SINTEF and NTNU’s Centre for Environmental Design and Renewable Energy have decided to study the situation by examining the relationship between Trondheim Energy’s power regulation regimes and salmon conditions in the Nidelva River in Trondheim. They will tag wild salmon and follow how the river’s overall salmon population changes over time. The goal is to identify measures that will enable energy production and fish to coexist.
