The Federal Energy Regulatory Commission on Aug. 5 approved a March 3 application from FFP Project 10 LLC for a preliminary permit to study the feasibility of the proposed Allegheny Lock and Dam #4 Hydroelectric Project.
This facility, to be developed by this affiliate of Boston-based Free Flow Power, would be located at the U.S. Army Corps of Engineers’ Allegheny Lock and Dam #4 on the Allegheny River in Allegheny County, Pa.
The proposed project would consist of: a new 150-foot-wide by 200-foot-long intake; a new 150-foot-wide by 200-foot-long powerhouse; a new 150-foot-wide by 300-foot-long tailrace; new 250-foot-long and 150-foot-long concrete retaining walls upstream of the new intake and downstream of the new powerhouse, respectively; three horizontal Kaplan turbine-generators each rated at 5 MW; a 20-megavolt-ampere, 4.16-kV/69-kV three-phase step-up transformer; a new 40-foot-wide by 40-foot-long substation; and a new 69-kV transmission line approximately 1,630 feet long from the new substation to an existing substation.
The estimated annual generation of the Allegheny #4 Project would be 89 gigawatt-hours.
During the three years covered by this permit, the commission expects that the permittee will carry out prefiling consultation and study development leading to the possible development of a license application.
