High-performance, FishSafe™ engineering

WHAT WE DO

Natel specializes in data-driven hydraulic design of FishSafe™ hydropower turbines to improve downstream fish passage. We use proprietary computer modeling and scale-model testing to reliably predict fish passage survival. We partner with established turbine manufacturers to implement our designs at large and small hydropower projects.

Our technology

FishSafe™ Turbine Designs

By delivering exceptional downstream fish passage survival and up to 5x longer blade life in sediment-laden environments, Natel’s FishSafe™ turbines provide a smarter, more cost-effective path to plant modernization. Savings in both CapEx and OpEx enable two to ten times the accelerated return on investment. Increase output by up to 10% by avoiding flow losses to bypasses and head losses to fine screens.
