U.S. seeks turbine refurbishment at 28.5-MW Minidoka hydro project

The Bureau of Reclamation seeks bids to overhaul two hydropower turbines at the Allen E. Inman power plant of the 28.5-MW Minidoka hydroelectric project on the Snake River in Idaho. A site visit is scheduled Nov. 20, with bids due Jan. 8, 2015.

Reclamation recruited firms in 2013 to repair gate equipment at Minidoka Dam, an 86-foot-tall zoned earthfill structure that began operating in 1909. It awarded a $21.32 million contract to Record Steel and Construction Inc. in 2011 to construct new spillways and canal headworks. The agency issued a record of decision in 2010 calling for replacement of the structures, which had deteriorated to a point of possible failure.

Reclamation now seeks bids to overhaul the two turbines in the Inman powerhouse, Units 8 and 9, totaling 20 MW. Minidoka’s original powerhouse contains two other operating units, Units 6 and 7, totaling 8.5 MW. Five units at the plant have been retired.

Work is to include refurbishing the horizontal turbine runners of Units 8 and 9 including furnishing and installing new mechanical seals, and furnishing and installing new digital governors. The work is valued at $5 million to $10 million.

A solicitation notice may be obtained from the Federal Business Opportunities Internet site, www.fbo.gov, by entering solicitation No. R14PS00485 in the “Keyword/Solicitation #” box. A site visit is scheduled Nov. 20.

Bids are due Jan. 8. For information, contact Rebecca Thomson, Contracting Officer, Bureau of Reclamation, Pacific Northwest Region, 1150 N. Curtis Road, Suite 100, Boise, ID 83706-1234; (1) 208-378-5107; Fax: (1) 208-378-5108; E-mail: rthomson@usbr.gov.
