Problem
Hydropower turbines often cause high downstream fish mortality and experience accelerated blade erosion, leading to regulatory challenges and increased operational costs for plant owners. Traditional turbine designs also suffer from flow losses that reduce overall generation efficiency. These issues limit the economic and environmental viability of both new and retrofit hydro projects.
Solution
Natel Energy applies data‑driven hydraulic engineering to create FishSafe™ turbine designs that maximize downstream fish passage survival while enhancing turbine performance. Using proprietary computational fluid dynamics (CFD) models combined with high‑fidelity scale‑model testing, the company predicts fish survival rates and blade wear for Kaplan, Francis, and propeller‑style turbines. The engineered turbines achieve up to 94% peak hydraulic efficiency and demonstrated 98‑100% fish passage survival, extending blade life by up to five times in sediment‑laden conditions. By reducing the need for bypass channels and fine screens, the designs can increase plant output by up to 10% and lower both capital and operating expenditures, delivering faster return on investment for hydro operators.
Target Audience
The primary customers are hydroelectric plant owners and operators, turbine manufacturers, and engineering firms undertaking new construction or retrofit projects that require fish‑friendly, high‑efficiency turbine solutions. Regulatory bodies overseeing aquatic ecosystem protection also benefit from the validated fish passage data.
