Natel Energy developed a modular hydropower concept called Restoration Hydro, which incorporates the company’s Restoration Hydro Turbine. This modular approach can help expand hydropower while supporting safe fish passage, river channel connectivity, and watershed restoration efforts.
The design process began with detailed site selection criteria that emphasized combining watershed restoration efforts with new hydropower development. Project partner Natural Systems Design led the initial site search, and the team narrowed options to alluvial pockets, which are wider stretches of a river where sediment-rich floodplains are bounded upstream and downstream by steeper, more confined river reaches. These pockets were found to be ideal targets for simultaneous hydropower development and watershed restoration activities such as floodplain reconnection with other river systems, elevated water tables, recharged aquifers, and increased overall wildlife habitat.
Project partners—including McLaughlin Whitewater; University of California, Berkeley’s Environmental Systems Dynamics Laboratory; Oak Ridge National Laboratory; Small Hydro Consulting, LLC; and Wells Engineering, LLC—also collaborated to create a facility design that supports downstream and upstream fish and sediment passage.
Through this project, Natel developed a framework to identify potential sites for modular hydropower development and a blueprint for future site and facility design using this concept.
Innovations for Low-Impact Hydropower Growth Projects
-
Researchers created the waterSHED tool to help demonstrate the design, operation, and feasibility of new, small hydropower projects at streams and sites with existing water infrastructure.
-
Oak Ridge National Laboratory developed two tools and published a report to aid developers making decisions about whether to add power-generating infrastructure to dams that currently do not generate power.
-
An Oak Ridge National Laboratory report found opportunities to develop hydropower on conduits in every state, totaling 1.41 gigawatts of new generating potential.
-
Researchers created and tested a composite hydropower turbine runner blade and found it performed nearly identically to traditional blades made of stainless steel.
-
Natel Energy’s Restoration Hydro Turbine is the first in the industry to enable safe passage for large and small fish while also meeting installation configurations for a wide variety of hydropower facilities.
