Fish Inclusion for Hydropower

11jan7:00 pm8:00 pmFish Inclusion for Hydropower

Event Details

Migration corridors for riverine species tend to overlap with valuable hydropower resources. Supporting clean hydroelectric power generation while also protecting freshwater diversity is in many cases an unmet challenge. Exclusion infrastructure (i.e., fine fish screens, behavioral guidance infrastructure, and bypasses) can protect fish from turbine entrainment when it is feasible, but also limits the available passage routes for fish and constrains hydropower generation. Alternatively, turbines designed to pass fish downstream safely can maintain connectivity for downstream migrating species while also enabling uninterrupted hydropower operation. Integrating safe downstream passage into normal hydropower operations through the use of fish-safe turbines (fish inclusion) can reduce cost and complexity while facilitating downstream migration. We will describe the function and application range of a new propeller-style turbine, called the Restoration Hydro Turbine (RHT), as well as passage testing learnings and results for American eel, Alewife, and Rainbow trout.

We have invited Abe Schneider and Sterling Watson from Natel Energy to share their work on fish-safe turbines. Natel Energy are creating a new kind of climate-resilient hydropower that prioritizes biodiversity alongside energy generation using fish-safe turbines, techniques from river restoration, and AI-powered decision making tools.
