Energy Resources seeks permit on 18-MW hydro project on the Arkansas River

Energy Resources USA Inc. applied June 26 at the Federal Energy Regulatory Commission for a preliminary permit for the proposed Col Charles D. Maynard Lock and Dam Hydroelectric Project, which would use the existing Col Charles D. Maynard Lock and Dam structure, also known as Lock and Dam 5, located on the Arkansas River approximately thirteen miles northwest of Pine Bluff, Arkansas, in Jefferson County, Arkansas.

The project facilities are owned and operated by the U.S. Army Corps of Engineers, Tulsa District.

A preliminary permit allows three years of exclusivity for project feasibility work, with a license application then needed if the decision is to advance the project further.

The applicant said it 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 northwest from the substation and following the existing access road to Jefferson Rd where it continues to the potential interconnection point. The potential interconnection point is an existing T-line 69 kV.

This project would consist of four vertical Kaplan turbine-generators rated at 4.5 MW each, to be installed in a powerhouse, for a total capacity of 18 MW. The estimated average annual production is 123.7 GWh. The hydraulic head used for estimating capacity and energy output is 17.11 feet. The turbines and generators will be newly manufactured for the project.
