Nuvista Light and Electric Cooperative LLC in Alaska told the Federal Energy Regulatory Commission on July 26 that it made progress on various fronts over the last six months on a 13.4-MW hydro project.
In August 2012, FERC granted a preliminary permit to study the feasibility of the proposed Chikuminuk Lake Hydro Project No. 14369, to be located on the Allen River, 118 miles southeast of Bethel, Alaska. A preliminary permit gives a party a 36-month exclusive right to look at project feasibility, with updates to be filed with FERC every six months and a license application needed if the decision is to move forward with the project.
The proposed project would include: an approximately 1,325-foot-long, 128-foot-high concrete-faced rockfill dam; a 150-foot-long, 75-foot-wide powerhouse containing two vertical Francis turbine/generator units rated for 6.7 MW each, for a total installed capacity of 13.4 MW; and a 118-mile long, 138-kV transmission line leading from the powerhouse to a substation in the town of Bethel. The estimated annual generation of the Chikuminuk Project would be 88.7 gigawatt-hours.
In the July 26 update report, Nuvista said it has been pursuing various community outreach and project permitting initiatives. Nuvista said it has completed a Draft Preliminary Application Document (PAD) that will be eventually filed with the FERC. The filing of this PAD has been postponed to early 2014.
