The Federal Energy Regulatory Commission on April 14 issued an original major license to BOST3 Hydroelectric LLC to construct, operate, and maintain its proposed Red River Lock and Dam No. 3 Hydroelectric Project.
The 36.2-MW project will be located at the U.S. Army Corps of Engineers’ Lock and Dam No. 3 on the Red River near the town of Colfax in Natchitoches Parish, La.
In November 2013, BOST3 had amended the 2010 application to replace its proposed 6.5-mile-long transmission line with 2,550 feet of transmission line and a switching station to be located within the project boundary, approximately 1,050 feet downstream of the powerhouse.
The Corps’ Lock and Dam No. 3 is one of the five Corps’ locks and dams that comprise the J. Bennett Johnston Waterway. Lock and Dam No. 3 consists of: a 40-foot-high by 423-foot-long concrete gravity dam with six 60-foot-wide Tainter gates; a 305-foot-long overflow weir; a 9,500-acre reservoir (Pool 3) at a normal surface elevation of 95 feet National Geodetic Vertical Datum (NGVD); and an 84-foot-wide by 685-foot-long navigation lock on the northeast bank of the Red River.
New facilities will include a 36.2-MW horizontal Kaplan bulb turbine/generator unit. Of the 62 acres within the project boundary, 61.8 acres are federal land administered by the Corps and 0.2 acre is land owned by the Central Louisiana Electric that will be used to connect the project transmission line to Central Louisiana Electric’s transmission line.
