FERC issues permit to Arkansas Electric for 36-MW hydro project

The Federal Energy Regulatory Commission on June 3 picked Arkansas Electric Cooperative Corp. (AECC) as the winner for a preliminary permit on a hydroelectric project in Arkansas.

In March 2015, Arkansas Electric Cooperative filed an application for a preliminary permit under which it would spend up to three years studying the feasibility of the proposed Col. Charles D. Maynard Lock and Dam Hydropower Project, to be located at the U.S. Army Corps of Engineers’ Col. Charles D. Maynard Lock and Dam on the Arkansas River in Jefferson County, Arkansas. A license application would be needed to take the project further.

In June 2015, Energy Resources USA Inc. filed an application for a competing preliminary permit at the same site.

  • AECC’s project would consist of: a 800-foot-long, 400-foot-wide intake channel; a 200-foot-long, 210-foot-wide powerhouse containing four generating units with a total capacity of 36 MW; a 1,000-foot-long, 400-foot-wide tailrace; a substation; and a 4-mile-long, 115-kV transmission line. The project would have an estimated average annual generation of 140,000 megawatt-hours, and operate as directed by the Corps.
  • Energy Resources’ proposed project would have consisted of: a 100- foot-long overflow bank extension connecting to the existing dam; a 770-foot-long, 300-foot-wide intake channel with a 85-foot-long retaining wall; a 220-foot-long, 90- foot-wide powerhouse containing four generating units with a total capacity of 18 MW; a 1,000-foot-long, 220-foot-wide tailrace with a 85-foot-long retaining wall; a substation; and a 3-mile-long, 69-kV transmission line. The project would have an estimated average annual generation of 123,700 megawatt-hours, and operate as directed by the Corps.

Said the June 3 FERC order: “Because AECC has the first-filed application, the preliminary permit is issued to AECC for the Col. Charles D. Maynard Lock and Dam Hydropower Project No. 14665.”
