The Federal Energy Regulatory Commission March 3 granted a November 2014 application from CC Energy LLC for a preliminary permit to study the feasibility of the proposed Carlo Creek Hydroelectric Project.
Ths project is located on Carlo Creek about 15 miles north of the Native Village of Cantwell in Denali Borough, Alaska. It would consist of the following new facilities: a 50-foot-long, 10-foot-high concrete diversion weir located on Carlo Creek; a 10,500-foot-long, 2.5-foot-diameter steel penstock; a 25-foot-long, 35-foot-wide concrete powerhouse; a 1.6-MW Pelton turbine/generator; a 10-foot-long, 10-foot-wide, 5-foot-deep concrete tailrace discharging flows from the powerhouse back to Carlo Creek; and a 1,500-foot-long, 15-kV transmission line interconnecting with an existing Golden Valley Electric Association 15-kV distribution line.
The estimated annual generation of the Carlo Creek Project would be 6.3 gigawatt-hours. During the course of the permit, CC Energy is expected to develop a license application for this project.
Said the March 3 order: “A preliminary permit is issued for the Carlo Creek Hydroelectric Project No. 14645 to CC Energy, LLC 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.”
