Free Flow Power Corp. (FFP) is seeking a license from the Federal Energy Regulatory Commission (FERC) to develop a hydroelectric project at the Enid Dam on the Yocona River in Yalobusha County, Miss.
The application was filed June 25 at FERC for the Enid Lake Hydroelectric Project by FFP Missouri 2 LLC, a domestic limited-liability company for which Free Flow Power is authorized to act as an agent.
The project will utilize the existing dam owned and operated by the U.S. Army Corps of Engineers (USACE), and operate in a run‐of‐release mode. FFP was issued a three-year preliminary permit for this project by FERC in December 2010.
The project site is about 6.5 miles north of the town of Oakland, Miss., and will involve the construction of a new 4.6-MW facility. The primary purpose of the existing USACE facility is for flood control and the facility also provides recreational opportunities for the public.
A new concrete powerhouse will be built on the north bank, downstream of the existing stilling basin adjacent to the river channel and contain two identical turbine-generator units with a combined installed capacity of 4,600 kW. Two new identical vertical Kaplan turbines will be installed in the powerhouse.
The project will have an installed capacity of 4.6 MW, an average annual energy production of 17.7 gigawatt hours (GWh) and an average monthly energy production of 1.46 GWh.
A new substation will be constructed about 550 feet west-northwest of the existing outlet works at the toe of the dam. Project output will be transmitted from the powerhouse to the new substation via a buried medium voltage cable. A new overhead transmission line will extend west from the substation to an interconnection point at the utility owned distribution line.
