Arkansas Electric wins FERC permit on 39.6-MW hydro project

The Federal Energy Regulatory Commission on June 3 granted a preliminary permit to one company for a hydroelectric project in Arkansas, while rejecting a competing application from another company.

In March 2015, Arkansas Electric Cooperative Corp. (AECC) filed an application for a preliminary permit os it could study the feasibility of the proposed David D. Terry Lock and Dam #6 Hydropower Project, to be located at the U.S. Army Corps of Engineers’ David D. Terry Lock and Dam #6 on the Arkansas River in Pulaski County, Arkansas.

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

  • AECC’s proposed project would consist of: a 600-foot-long, 500-foot-wide intake channel; a 200-foot-long, 210-foot-wide powerhouse containing four generating units with a total capacity of 39.6 MW; a 1,100-foot-long, 400-foot-wide tailrace; a substation; and a 4-mile-long, 115-kilovolt (kV) transmission line. The proposed 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 consist of: a 100-foot-long overflow bank extension connecting to the existing dam; a 770-foot-long, 200-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 500-foot-long, 200-foot-wide tailrace with a 85-foot-long retaining wall; a substation; and a 4-mile-long, 69-kV transmission line. The proposed project would have an estimated average annual generation of 128,200 megawatt-hours, and operate as directed by the Corps.

In this case, FERC picked the application that was first to be filed. Said the June 3 order: “A preliminary permit is issued for the David D. Terry Lock and Dam #6 Hydropower Project No. 14664 to Arkansas Electric Cooperative Corporation, for a period effective the first day of the month in which this permit is issued, and ending either 36 months from the effective date or on the date that a development application submitted by the permittee has been accepted for filing, whichever occurs first. The competing preliminary permit application filed by Energy Resources USA, Inc., for the David D. Terry Lock and Dam Hydroelectric Project No. 14686 is denied.”
