Welcome to our weekly newsletter focusing on environmental trends and solutions driving us towards a more sustainable future.
Hey there, I’m Alexandra. We came across a concerning story about eels facing a significant threat at hydro dams. If this were birds and windmills, it would likely cause an outcry. These eels deserve safe passage through their habitats. Let’s explore a company developing a technological solution to this issue.
This week, we delve into the following topics:
– Eels facing mortality in hydro dam turbines: A novel design offers hope

Every year, a large number of endangered American eels migrate down the St. Lawrence River en route to their breeding grounds in the Sargasso Sea. Unfortunately, many perish due to collisions with the turbine blades of hydroelectric dams along the river, contributing to a drastic decline in their population since the 1970s.
Natel Energy, a California-based startup specializing in fish-friendly turbines, has devised a solution to prevent these fatalities without compromising power generation efficiency. By introducing a new turbine runner design, the company aims to safeguard the eels during their migration.
American eels play a crucial ecological role in the region and hold cultural significance for Indigenous communities. However, overfishing, habitat loss, and hydroelectric dams have led to a sharp decline in their numbers. Efforts to protect the eels have included bans on commercial fishing and initiatives to assist their migration past hydro plants.
Natel’s innovative “FishSafe” turbine design incorporates features like curved blades and reduced blade-housing gaps to minimize harm to fish. Simulations suggest a remarkable increase in eel survival rates, offering a promising outcome without compromising operational efficiency.
The company’s approach highlights the potential for modernizing existing hydropower facilities to prioritize environmental conservation without significant costs. By showcasing successful installations in Europe and engaging with Canadian companies, Natel Energy strives to revolutionize fish protection measures in the industry.
The new turbine design not only enhances fish survival rates but also demonstrates comparable efficiency to traditional models. Its ease of installation and operational benefits make it a viable option for upgrading aging hydropower infrastructure.
As Natel Energy continues its dialogue with industry stakeholders, the hope is that this technology will mark a significant turning point in the conservation of American eels.
