Free Flow Power seeks preliminary permits on four more projects

Project affiliates of Boston-based Free Flow Power applied May 17 at the Federal Energy Regulatory Commission for preliminary permits on four hydroelectric projects in Pennsylvania, Louisiana and Arkansas.

Preliminary permits give a party exclusive rights to explore project feasibility, with a later license application to be filed for any project deemed to be feasible.

FFP Project 132 LLC

This proposed project will be located at the Allegheny Lock and Dam #7 on the Allegheny River at river mile 45.7 above the confluence of the Ohio River, which is located in Kittanning, Armstrong County, Pa. The project will utilize the existing U.S. Army Corps of Engineers lock and dam that was placed into service in 1930. The proposed development of the site involves the construction of a new 16.5-MW hydropower facility at the northeastern end (left side) of the existing Allegheny Lock and Dam #7. Used would be three horizontal bulb turbine-generators, each rated at 5.5 MW, which will be installed in the new powerhouse for a total project installed capacity of 16.5 MW.

A 50-MVA 4.16/ 69-kV three-phase step-up transformer will be located in a new substation and adjacent to the powerhouse. The applicant has identified existing transmission infrastructure in the proposed project area. These existing transmission elements will be evaluated during the permit period through field investigations and discussions with the local utility. It is anticipated that the project will utilize a single overhead three phase, 69kV line which is approximately 2.3 miles in length, extending from the substation to an existing substation at a proposed interconnection point.

FFP Project 130 LLC

This project will use the existing Jonesville Lock and Dam structure, located on the Black River in Catahoula Parish County, La. The project facilities are owned and operated by the Corps. The project will utilize the existing lock and dam that was placed into service in 1972. The proposed development of the site involves the construction of a new 6-MW hydro facility at the south end (left side) of the existing Jonesville Lock and Dam. It would use three horizontal bulb turbine-generators, each rated at 2 MW.

A 50-MVA 4.16/ 69-kV three-phase step-up transformer will be located in a new substation and adjacent to the powerhouse. The applicant has identified existing transmission infrastructure in the proposed project area. These existing transmission elements will be evaluated during the permit period through field investigations and discussions with the local utility. It is anticipated that the project will utilize a single overhead three phase, 69-kV line which is approximately 10 miles in length, extending from the substation to an existing substation at a proposed interconnection point.

FFP Project 133 LLC

This project company is pursuing the Dashields Lock and Dam Hydroelectric Project, using an existing Corps lock and dam structure on the Ohio River. The location is at river mile 13.3 below the confluence of the Allegheny and Monongahela rivers, which is located near Ambridge, Allegheny County, Pa. The proposed development of the site involves the construction of a new 25-MW hydro facility at the northeastern end (right side) of the existing Dashields Locks and Dam. It would use five horizontal bulb turbine-generators, each rated at 5 MW, to be installed in the new powerhouse.

A 50-MVA 4.16/ 69-kV three phase step-up transformer will be located in a new substation and adjacent to the powerhouse. The applicant has identified existing transmission infrastructure in the proposed project area. These existing transmission elements will be evaluated during the permit period through field investigations and discussions with the local utility. It is anticipated that the project will utilize a single overhead three phase, 69kV line which is about 2 miles in length, extending from the substation to an existing substation at a proposed interconnection point.

FFP Project 131 LLC

This is the Felsenthal Lock and Dam Hydroelectric Project, that would be located on the Ouachita River at river mile 226.9, which is located in Union County, Ark. The project will utilize the existing Corps lock and dam that was placed into service in 1984. The proposed development of the site involves the construction of a new 5-MW hydropower facility at the eastern end (left side) of the existing Felsenthal Lock and Dam. It would use two horizontal bulb turbine-generators, each rated at 2.5 MW, which will be installed in the new powerhouse.

A 50-MVA 4.16/ 69-kV three phase step-up transformer will be located in a new substation and adjacent to the powerhouse.
