The Federal Energy Regulatory Commission has canceled the preliminary permit for the proposed 5.5-MW Hamilton Low Dam Hydroelectric Project, saying permittee kW River Hydroelectric did not submit a progress report due May 31, 2021.
FERC issued the preliminary permit for the project, to be located on the Great Miami River in Butler County, Ohio, on June 28, 2019. kW River Hydroelectric filed an application for a preliminary permit for the project on March 4, 2019.
The preliminary permit is canceled effective close of business on Sept. 9, 2021. No applications for this site may be submitted until after the cancellation is effective.
The Hamilton Low Dam Hydroelectric 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.
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.
