In September 2021, Natel conducted formal testing with PNNL on a cohort of American eel passing through the RHT test unit operating at 670 rpm under 10 m of hydraulic head. Following the test the eels were monitored for 48 hours with 100% survival.
An AUMA electric actuation solution ensures high-precision guide vane adjustment for a fully-submersible hydro turbine from Natel Energy at the Sauerbrunn hydropower plant.
FishSafe™ RHT designs are at the core of two research projects that have been recommended for funding by the U.S. DOE to advance the science required to engineer safer hydropower turbines.
