FERC issues preliminary permit for 4.5-MW Lower Coosawattee Hydroelectric Project in Georgia

The Federal Energy Regulatory Commission has issued a preliminary permit to Cherokee Rivers Company LLC to study the feasibility of the proposed 4.5-MW Lower Coosawattee Hydroelectric Project in the Coosawattee River in Georgia.

The project would be located at the Carter’s Reregulation Dam in Murray County, which is operated by the U.S. Army Corps of Engineers.

The proposed project would consist of a 50-foot-long, 8-foot-wide intake structure with trashracks and stop logs; four 8-foot-diameter, about 320-foot-long penstocks; two 15-foot-high, 23.6-foot-wide, 100-foot-long box culvert conduits; a 52-foot-long, 25-foot-wide, 47-foot-high powerhouse containing two turbine-generator units with a combined capacity of 4.5 MW; and a 120-foot-long transmission line.

The proposed project would have an estimated average annual generation of 16,500 MWh and operate in a run-of-release mode using surplus water from the Carter’s Reregulation Dam, as directed by the Corps.

Cherokee Rivers Company filed the application for the preliminary permit in April 2019. The FERC preliminary permit is effective Sept. 1, 2019, and lasts for 48 months.

The purpose of a preliminary permit is to preserve the right of the permit holder to have the first priority in applying for a license for the project that is being studied.

The Carters hydropower plant on the Coosawattee River has a generating capacity of 600 MW.
