U.S. extends call for turbine linkage upgrades at 810-MW Lower Granite hydro project

The U.S. Army Corps of Engineers has extended the deadline for bids to replace internal turbine hub linkage components at the 810-MW Lower Granite Dam hydroelectric project on the Snake River in Washington. Bids now are due June 17.

The Corps’ Walla Walla District previously called for bids by June 9. It awarded a contract in 2013 to American Babbitt Bearing Inc. for turbine unit rehabilitation work at Lower Granite and the 402-MW Dworshak project on the North Fork Clearwater River in Idaho. The Portland District called for bids by May 15 to install new digital governors at Lower Granite and eight other Corps hydroelectric projects in the Portland and Walla Walla districts.

Lower Granite Unit 1 was blocked to be a fixed-blade runner after inspection discovered cracks in the eye end and blade lever link pins. The Corps seeks bids to replace internal hub linkage components with government-furnished parts. The turbine is a Kaplan-type manufactured by Baldwin-Lima-Hamilton with a generator manufactured by Westinghouse. 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. W912EF15R0015 in the “Keyword/Solicitation #” box.

Bids now are due by 2 p.m., Pacific time, June 17. For information, contact Kent Bernard, Jani Long, U.S. Army Corps of Engineers, Walla Walla District, 201 N. Third Ave., Walla Walla, WA 99362-1876; (1) 509-527-7205; E-mail: kent.r.bernard@usace.army.mil, jani.c.long@usace.army.mil.
