Internal Hydro International Inc. has submitted a proposal to the Corps of Engineers to install 40 small hydro generating units at the Corps’ W. Kerr Scott Dam, on the Yadkin River near Wilkesboro, N.C.
Internal Hydro proposes to install its 30-kW Energy Commander V hydro units at the site, which it said would have an installed capacity of 1.2 MW and a projected annual revenue of $750,000. The firm said June 19 it would work with the Corps to complete the proposal process and a revenue sharing plan.
Internal Hydro describes its Energy Commander as a positive displacement system that differs from traditional turbine technology in that it uses cylinders and a patented control valve to take in a low pressure flow, through a small inlet, using all the flow inside the cylinders to create mechanical forces for a generator.
The company anticipates the W. Kerr Scott Dam project would demonstrate the technology to the Corps and other dam owners. The technology has not previously been installed at a dam to generate hydropower.
Internal Hydro said the technology can be used to generate electricity from waste water, fluid, or gas flow from any source where flow pressure is present.
