The Federal Energy Regulatory Commission on Nov. 1 issued a preliminary permit to FFP Project 131 LLC, a unit of Boston-based Free Flow Power, on a 5-MW hydro project in Arkansas.
The permit gives the company an exclusive three years to study the feasibility of the Felsenthal Lock and Dam Hydroelectric Project, which would be located at the U.S. Army Corps of Engineers’ Felsenthal Lock and Dam on the Ouachita River near the town of Felsenthal in Union County, Ark.
The proposed project would consist of: a 300-foot-long, 150-foot-wide intake channel; a 100-foot-long, 150-foot-wide powerhouse containing two generating units with a total capacity of 5 MW; a 500-foot-long, 150-foot-wide tailrace; a 4.16/69 kV substation; and a 1.0-mile-long, 69-kV transmission line.
The proposed project would have an average annual generation of 18,000 megawatt-hours and would operate in a run-of-river mode as directed by the Corps.
The U.S. Fish and Wildlife Service expressed some concerns about the project, but FERC said any such issues can be addressed if and when this project moves to the licensing stage.
