FERC grants two permits for Free Flow Power hydro projects

The Federal Energy Regulatory Commission on Nov. 14 issued two preliminary permits to affiliates of Boston-based hydro developer Free Flow Power for projects in the southeast U.S.

On April 2, FFP Project 123 LLC had filed an application for a preliminary permit to study the feasibility of developing the Amory Lock and Dam Hydropower Project, which would be located at the U.S. Army Corps of Engineers’ Amory Lock and Dam on the Tennessee-Tombigbee Waterway near the town of Amory in Monroe County, Miss.

The proposed project would consist of: a 100-foot-long, 60-foot- wide forebay; a 60-foot-long, 70-foot-wide powerhouse containing one generating unit with a total capacity of 1.5 MW; a 700-foot-long, 60-foot-wide tailrace with a 300-foot-long retaining wall; a 4.16/36.7 kV substation; and a 1-mile-long, 36.7-kV transmission line. The project would have an average annual generation of 7,100 megawatt-hours and operate as directed by the Corps.

Also approved on Nov. 14 was a preliminary permit, filed for on April 2 by FFP Project 124 LLC, to study the feasibility of the Red River Lock and Dam #1 Hydroelectric Project, which would be located at the Corps’ Red River Lock and Dam #1 on the Red River, near the town of Marksville in Catahoula Parish, La.

This proposed project would consist of: a 575-foot-long, 270-foot-wide forebay with a 200-foot-long retaining wall; a 200-foot-long, 270-foot-wide powerhouse containing four generating units with a total capacity of 36.8 MW; a 500-foot-long, 270-foot-wide tailrace with a 200-foot-long retaining wall; a 4.16/69 kV substation; and a 0.4-mile-long, 69-kV transmission line. The project would have an average annual generation of 163,200 megawatt-hours and operate as directed by the Corps.

If the feasibility works pans out under a preliminary permit, then a developer needs to seek a hydro license from FERC.
