U.S. seeks generator rewinds, intake refurbishment planned, at 140-MW Trinity hydro project

Trinity Hydropower Project

The Bureau of Reclamation seeks bids to rewind two generators at the 140-MW Trinity hydroelectric project on the Trinity River in California. Site visits are scheduled April 16 and 21, with bids due June 2.

The agency also announced it plans to seek bids for intake mechanical equipment refurbishing and gate shaft refurbishing at Trinity.

Reclamation requested information in January on firms able to perform the generator rewinds. It also took bids in January to replace penstock flowmeters at Trinity and seven other hydroelectric projects in its northern and central California areas. Last year, the agency took bids to rebuild the cooling water strainers used in the generator and bearing cooling water systems at Trinity.

Reclamation now seeks bids to rewind two generators and furnish appurtenant components and services. The work is valued at $10 million to $25 million.
