Gia Schneider, co-founder and CEO of Natel Energy, discusses the challenges of generating hydroelectric power without damaging the ecosystem. She explores the negative impact of dams and turbines on rivers and aquatic life, and the importance of fish-friendly turbines. Schneider also talks about current projects, the concept of restoration hydro, and the future of clean energy.
Natel Energy has developed a turbine with a leading edge design that reduces fish mortality to less than 2%, compared to the average 20% with conventional turbines, providing a fish-safe solution for hydroelectric power generation.
Restoration hydro, inspired by nature and beaver dams, reintroduces natural flow barriers and log jams into rivers, leading to positive environmental impacts such as groundwater recharge, flood mitigation, and increased habitat diversity for fish.

Building a Fish-Friendly Turbine
Gia Schneider's company, Natel Energy, aims to solve the problem of hydroelectric power harming fish. To achieve this, they have designed a turbine with a leading edge that mitigates fish mortality. The blade's thick leading edge and rounded shape minimize the chances of direct strikes and create a deflection zone that helps fish navigate through without harm. Through extensive testing, the turbine was found to have less than 2% fish mortality, compared to the average 20% with conventional turbines. The turbine is also designed to maintain high power generation efficiency, with its performance reaching up to 93%. This innovation provides a fish-safe solution for upgrading existing hydroelectric plants.
Restoration Hydro and Dam Reconfiguration
In addition to developing a fish-safe turbine, Schneider envisions a future of restoration hydro. Inspired by nature, particularly beaver dams, this approach seeks to reintroduce natural flow barriers and log jams into rivers. These structures have positive environmental impacts, such as groundwater recharge, flood mitigation, and increased habitat diversity for fish. Schneider believes that by reimagining hydroelectric projects with this nature-based approach, it can address the challenges of climate change, improve water resource management, and contribute to the renewable energy supply. In some cases, existing dams that have limited ecological or commercial value could be removed, while reconfiguring others can enhance upstream fish passage and ecosystem sustainability.
Environmental Priorities in the Clean Energy Transition
Schneider emphasizes the importance of prioritizing biodiversity and environmental criteria across the clean energy sector. While transitioning from fossil fuels to renewable energy sources is crucial, the manner in which it is done can greatly impact biodiversity and environmental health. Reflecting on the history of hydroelectric power, Schneider encourages considering lessons learned in embedding criteria that prioritize sustainability and positive environmental outcomes. This holistic approach should extend beyond hydro to encompass other sectors like batteries, solar, and wind, ensuring that the path to clean energy aligns with environmental goals.
Gia Schneider is the co-founder and CEO of Natel Energy, a company that is trying to transform the way hydroelectric power works. Gia’s problem is this: how do you draw hydropower from rivers without damaging the ecosystem? As it turns out, we have a lot to learn from nature’s furriest engineers – beavers.
