Natel Energy develops and produces hydraulic turbines FishSafe that improve fish passage, modernize existing power plants and ensure reliable megawatts of grid power. The company uses computer modeling and scale model testing before integrating turbine into existing hydropower plant. It's collaborating with leading turbine manufacturers to implement its designs in hydropower projects worldwide. FishSafe turbines feature thick, forward-curved blades. They ensure 98-100% fish survival rate when passing through them, minimize wear from sediment, extend service life, save money on blade repairs and increase plant productivity by up to 10% by preventing flow losses in bypasses and pressure losses in fine mesh.
