Natel Energy, a California-based startup focusing on fish-friendly turbines, has developed a new turbine design to prevent the deaths of American eels at hydroelectric dams. These endangered eels face a high mortality rate due to collisions with turbine blades as they migrate down the St. Lawrence River. The new turbine runners, designed by Natel Energy, aim to reduce these fatalities without compromising power generation efficiency.
The American eels play a crucial role in Canada’s ecosystem, being the only true catadromous species in the country. Their decline in numbers is attributed to various factors such as overfishing, habitat loss, and interactions with hydroelectric dams. The new “FishSafe” turbine design features curved blades with a blunt leading edge, reducing the risk of injury to fish that come into contact with them. Additionally, the design maintains efficiency comparable to existing turbines and can be easily integrated into current systems without extensive modifications.
Natel Energy’s innovative solution has the potential to significantly increase the survival rate of American eels passing through hydroelectric dams. The company aims to demonstrate to hydro dam operators that prioritizing fish survival can be achieved without detrimental effects on their operations. By implementing these fish-friendly turbines, Natel Energy hopes to contribute to the preservation of the American eel population and promote sustainable energy practices in the industry.
In collaboration with Canadian companies and recent installations in France, Natel Energy is paving the way for a more environmentally conscious approach to hydropower generation. The successful testing of these new turbine runners with live eels underscores the potential impact of this technology on safeguarding aquatic species and promoting biodiversity in water ecosystems.
The efforts of Natel Energy reflect a growing awareness of the importance of balancing energy production with environmental conservation. By addressing the challenges faced by American eels at hydroelectric dams, the company is at the forefront of promoting sustainable practices in the renewable energy sector. The development and adoption of fish-friendly turbine designs represent a positive step towards creating a harmonious coexistence between energy generation and wildlife preservation.
