Hydro Green Energy on behalf of Lock+ Hydro Friends Fund XII applied Sept. 11 at the Federal Energy Regulatory Commission for a preliminary permit for the 9-MW Selden Lock and Dam Hydropower Project, to be located on the Hepburn Street Dam on the West Branch of the Susquehanna River near Williamsport, Pa.
A preliminary permit for a proposed project on the Hepburn Street Dam was cancelled by FERC on June 25, opening the way for this new application, which would cover a permit term of three years. A permit like this is a precursor to a license application, which would be filed if the developer decides to move ahead with the project.
The output from the uni-directional turbines will be generated by the flow of the Susquehanna River. The project will operate in run-of-river mode. The generated power would be delivered to the grid via a new transmission line that will connect to an existing substation.
The hydropower development will consist of one Large Frame Module (LFM) of ten hydropower turbines, which will be installed adjacent to the dam in the existing levee north of the dam. The LFM will contain flow control door assemblies that can open and close off flow to the units during an event that would require a suspension of generation. The dimensions of the project are expected to be 150 feet wide by 25 feet deep.
The project’s tailrace will be approximately 150 feet wide and extend no more than 150 feet downstream. The tailrace will be lined with standard riprap. The adjacent switchyard and control room will measure approximately 25 feet by 50 feet.
Each of the ten turbines will have a nameplate capacity of approximately 900 kW. The entire system of turbines should produce approximately 9 MW based on data and efficiency calculations conducted by the applicant.
The generated power will connect to the electric grid with the installation of a new transformer in a new switchyard. A new 69-kV transmission line will run approximately 1,000 feet to connect to an existing substation. The project is expected to generate approximately 51,000 MWh.
