Free Flow Power (FFP) is seeking a license from the Federal Energy Regulatory Commission (FERC) to develop a 4.6-MW hydroelectric project at the Enid Dam on the Yocona River in Yalobusha County, Miss.
The applicant for this project, called the Enid Lake Hydroelectric Project, is FFP Missouri 2 LLC, 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). The project will operate in a run‐of‐release mode and, as such, will not alter or adversely affect current or future USACE operations, the Nov. 13 application said.
FFP was issued a three-year preliminary permit for this project from the FERC on Dec. 1, 2010, which expires on Nov. 30, 2013.
A new concrete powerhouse will be built on the north bank, downstream of the existing stilling basin adjacent to the river channel. Two new identical vertical Kaplan turbines will be installed in the powerhouse.
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.
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.
“Power generated by the Project will be available to meet demand of the Tennessee Valley Authority (TVA) sub-region within the Southeast Electric Reliability Corporation (SERC), one of the regional entities of the North American Electric Reliability Corporation (NERC),” said the application. “The Project will be owned and operated by the Applicant and energy (and capacity as applicable) will be sold under a power purchase agreement to an entity such as TVA, utility company, aggregator, or other such wholesale purchaser of electric generation.”
