Hydro plant modification sought to restore U.S. Battle Creek habitat

The Bureau of Reclamation plans to seek bids for powerhouse bypass work in the 37.9-MW Battle Creek hydroelectric project to implement one of United States’ largest cold water anadromous fish restoration efforts. Bids are expected to be due April 12.

The Battle Creek Salmon and Steelhead Restoration project includes removal or retrofitting of dams in Pacific Gas & Electric Co.’s Battle Creek project in California. (HydroWorld 1/27/09) The Interior Department received $26 million in stimulus money from the American Recovery and Reinvestment Act of 2009 for the project. (HydroWorld 4/15/09)

PG&E will continue to operate the project’s five hydropower plants. However, less water will pass through three plants, 7-MW South, 8-MW Inskip, and 13-MW Coleman. Generation at 9-MW Volta and 900-kW Volta 2 will be unaffected.

The Bureau of Reclamation said it plans to issue a solicitation in March for construction of a direct connection from the Inskip powerhouse tailrace to the Coleman Canal. It is to include 3,700 feet of 66-inch-diameter buried concrete pressure pipe; 300 feet of 72-inch-diameter buried concrete pressure pipe; a cast-in-place concrete intake structure and three reinforced concrete energy dissipater structures; a 700-foot cast-in-place concrete chute; relocation of an existing fish hatchery water supply line; and related site work, diversion works, metalwork, and mechanical and electrical equipment.

The work is expected to cost between $5 million and $10 million.

A pre-solicitation notice may be obtained from the Federal Business Opportunities Internet site, www.fbo.gov, by entering Solicitation No. R10PS20R42 in the “Keyword/Solicitation #” box.

Bids are expected to be due April 12. For information, contact Bettye Lou Mahoney, Contract Specialist, Bureau of Reclamation – MP, Regional Office, 2800 Cottage Way, Room E-1815, Sacramento, CA 95825; (1) 916-978-5570; E-mail: bmahoney@usbr.gov.
