Energy Resources USA Inc. applied June 25 to the Federal Energy Regulatory Commission for a preliminary permit for the proposed Columbia Lock and Dam Hydroelectric Project, which would use the existing Columbia Lock and Dam structure located on the Arkansas River, about five miles northwest of Columbia, Louisiana, in Caldwell County, Louisiana.
The project facilities are owned and operated by the U.S. Army Corps of Engineers, Tulsa District.
This permit would allow the company three years of exclusivity to explore the feasibility of the project, with a license application then needed if the decision is to take the project further.
The company plans two vertical Kaplan turbine-generators rated at 4.5M W each, to be installed in a new powerhouse, for a total capacity of 9 MW. A 12 MVA 4.16/69 kV three-phase step-up transformer will be located adjacent to the powerhouse in a new, 50-foot wide by 60-foot long substation.
The applicant has identified existing transmission infrastructure in the proposed project area. These existing transmission elements will be evaluated during the permit period through field investigations and discussions with the local utility. It is anticipated that the project will utilize a single overhead three-phase, 69-kV line which is approximately three miles in length, extending west from the substation and it continues to the potential interconnection point.
The estimated average annual production is 59.6 GWh. The hydraulic head used for estimating capacity and energy output is 17.4 feet. The turbines and generators will be newly manufactured for the project.
