Colorado town awards equipment contract for 1.05-MW Castle Creek

The city of Aspen awarded a $1.3 million contract to Canyon Industries Inc. to supply a turbine and generator for the 1.05-MW Castle Creek project.

Canyon Industries of Deming, Wash., was among five firms submitting proposals that included a total of nine options for configuring turbine and generator equipment. (HNN 12/12/07) Bid amounts ranged from $860,000 to $2.4 million, and included options for one or two turbines and one or two generators.

Project completion and commissioning tentatively are scheduled for fall 2009, the utilities engineer for Aspen Public Utilities said in March.

The city solicited proposals after Aspen voters approved ballot questions supporting redevelopment of a small hydro project on Castle Creek that was idle for nearly half a century.

Plans call for breaking ground for the project penstock in fall 2008. Construction of the building to house the single vertical shaft impulse-type turbine and generator is dependent on completion of the design review process.

The new Castle Creek project is to generate about 5,500 MWh annually, or about 8.5 percent of Aspen electric customers’ annual energy requirements. The facility also is expected to reduce carbon dioxide emissions by about 5,167 tons.
