The U.S. Bureau of Reclamation has awarded a US$1.7 million contract to Gardner Zemke Co. to replace the main bus at the 117-MW Keswick hydropower project in California.
Reclamation most recently sought bids for the work in August.
Per the contract, Gardner Zemke is to remove the 6.9-kilovolt phase bus and enclosure from each of the three Keswick generators, dispose of hazardous materials, the design and install replacements for each of the main isolated phase bus, and the test and commission the new equipment.
Keswick is part of the Trinity River Division of Reclamation’s Central Valley Project. Keswick Dam regulates flows in the Sacramento River downstream from 663-MW Shasta Dam. Also located on Keswick Reservoir is the 180-MW Spring Creek hydro project.
