Hydro Green seeks another permit on 10-MW Mississippi hydro project

Hydro Green Energy, on behalf of subsidiary Lock+ Hydro Friends Fund XVIII (HFF), filed an April 1 application for a successive preliminary permit with the Federal Energy Regulatory Commission for the John C. Stennis Lock and Dam Hydropower Project, to be located on the U.S. Army Corps of Engineers’ (USACE) John C. Stennis Lock and Dam on the Tombigbee River near Columbus, Miss.

A prior permit for this site expired on March 31. “This application is made in order so that the Applicant may secure and maintain priority of application for a license for the project under Part 1 of the Federal Power Act while obtaining the data and performing the acts required to determine the feasibility of the project and to support an application for the project,” the April 1 filing said.

The output from the uni-directional turbines will be generated by water diverted from the Tennessee-Tombigbee Waterway in a conduit. Flows to the hydro plant would be coordinated with the Corps. The project will operate in run-of-river mode. The generated power will connect to the electric grid with the installation of a new transformer in a new switchyard. A new 34.5-kV transmission line will connect power to the grid.

The hydropower development will consist of one lock frame module (LFM) consisting of five turbines. The LFM will be installed in a new conduit that transports water from the upper pool to the lower pool, along with 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 conduit’s dimensions will be determined after on-site visits. Each of the turbines will have a nameplate capacity of approximately 2,000 kW based on a recorded net head of 30 feet. The entire system of turbines should produce approximately 10 MW. The project is expected to produce 52,560 MWh annually.
