U.S. sets site visit for installation of new-design turbines at 603-MW Ice Harbor hydro project

The U.S. Army Corps of Engineers has scheduled a site visit for a pending solicitation for installation of new-design turbine runners and generator rewinds at the 603-MW Ice Harbor Dam hydroelectric project. The site visit is scheduled Sept. 16 with possible continuation on Sept. 17.

The Corps’ Walla Walla District took information Aug. 17 on firms able to characterize fish passage environment and to perform acoustic telemetry evaluation of juvenile salmon survival through the new-design units at Ice Harbor on the Snake River in Washington. It took information in April on firms able to perform biological assessments of the new turbine runner designs based on computational fluid dynamic model outputs.

Voith Hydro Inc. has completed design and model testing with the Corps’ Hydroelectric Design Center and the Walla Walla District for Kaplan runners at Ice Harbor. The three entities collaborated to develop the designs of a new fixed-blade propeller and a new adjustable-blade turbine runner designed with biological criteria to be safer for fish passage.

The Corps plans to seek bids to install a fixed-blade Kaplan runner in Unit 2 and adjustable Kaplan runners in Units 1 and 3. Work also is to include replacing other major steel components, rewinding generators, and supplying one stator core and three stator windings. The work is valued at $25 million to $100 million.

A pre-solicitation notice may be obtained from the Federal Business Opportunities Internet site, www.fbo.gov, by entering solicitation No. W912EF15R0044 in the “Keyword/Solicitation #” box. A site visit is scheduled Sept. 16 with possible continuation on Sept. 17.
