The Federal Energy Regulatory Commission has issued a preliminary permit to kW River Hydroelectric to study the feasibility of the proposed 5.5-MW Hamilton Low Dam Hydroelectric Project, to be located on the Great Miami River in Butler County, Ohio.
kW River Hydroelectric filed an application for a preliminary permit for the project on March 4, 2019.
The project would consist of 11 turbine modules, 37 feet long by 15 feet wide, each containing four 125-kW turbines and two three-phase AC generators. The project’s estimated annual generation is 3,066 MWh.
The preliminary permit was issued June 28, 2019, and ends either 48 months from the effective date or when a development application submitted by the permittee has been accepted for filing.
kW River Hydroelectric’s module is built around a Williams cross-flow turbine, which was developed by retired Air Force officer Fred Williams. The turbine is designed for low-head dams (with a head of less than 15 feet) and is installed on the downstream side of the dam, with the top of the device creating a slope from the top of the dam to the water surface.
FERC says: The purpose of a preliminary permit is to preserve the right of the permit holder to have the first priority in applying for a license for the project that is being studied.
