The Federal Energy Regulatory Commission on Dec. 16 said it has decided to issue a preliminary permit to FFP Project 133 LLC for a hydro project in Pennsylvania, over a competing application filed by Mid-Atlantic Hydro LLC.
On May 20, the FFP Project 133 affiliate of Boston-based Free Flow Power filed an application for a preliminary permit to study the feasibility of the proposed Dashields Lock and Dam Hydroelectric Project, to be located at the U.S. Army Corps of Engineers’ Dashields Lock and Dam on the Ohio River in Ambridge County, Pa.
On Aug. 30, Mid-Atlantic Hydro filed an application for a competing preliminary permit to study the feasibility of the proposed Dashields Lock and Dam Hydroelectric Project at the same site.
- FFP’s proposed project would include: five horizontal bulb turbine-generators each rated at 5 MW; a new substation; and a new 69-kV transmission line about 2 miles long from the new substation to an existing substation. The estimated annual generation is 120 gigawatt-hours.
- The Mid-Atlantic Hydro project would include: fourteen Very Low Head (VLH) 4000 turbine units with a total capacity of 7 MW; and a new 69-kV transmission line approximately 2.1 miles long. The estimated annual generation is 41.4 gigawatt-hours.
The Pittsburgh District Office of the Corps owns and operates the Dashields Locks and Dam. The existing Corps facilities consist of an operational land-side lock, an operational river-side lock, and a reinforced concrete dam with a long fixed-crest, uncontrolled spillway.
FERC said there was no qualitative difference between the applications, so it chose the first one to be filed as the winner. The preliminary permit was issued to FFP for a period effective the first day of the month in which this permit is issued, and ending either 36 months from the effective date or on the date that a development application submitted by the permittee has been accepted for filing, whichever occurs first.
