The city of Aspen seeks proposals for the supply and commissioning of one or two Pelton-type turbines, generators, and control systems for the 1.05-MW Castle Creek hydroelectric project. Proposals are due Jan. 24.
The request for proposals follows a vote by Aspen voters who approved two ballot questions supporting redevelopment of a small hydroelectric project on Castle Creek that has been idle for nearly half a century. (HNN 11/9/07)
The new Castle Creek project would use existing water rights, headgates, and water storage components of the original Castle Creek hydroelectric plant, which met all of Aspen’s electricity needs from 1892 through 1958. Restoring generating capacity will require construction of a new powerhouse and a penstock from a water plant to the powerhouse, installation of the two turbines and generators, and related electric system work.
A non-mandatory pre-proposal conference and site visit is planned Jan. 8. Proposals are due 2 p.m., Jan. 24. The city expects to notify the successful contractor Feb. 8, and the City Council is scheduled to decide on approval Feb. 25.
