Voith wins Corps contract for Ice Harbor hydropower plant turbine rehab work

The U.S. Army Corps of Engineers has awarded a contract worth $47,671,170 to Voith Hydro Inc. to provide services as part of ongoing modernizations of the 603-MW Ice Harbor hydroelectric plant on the Snake River in Washington.

Per the award, Voith Hydro will install a fixed-blade Kaplan runner on Ice Harbor’s Unit 2 and adjustable Kaplan runners in Units 1 and 3. The company will also replace other major steel components, rewind generators, and supply one stator core and three stator windings.

The Corps’ Walla Walla District most recently solicited bids for the work last October after having previously called for firms to perform fish passage assessments at Ice Harbor in August.

The work is not Voith Hydro’s first related to Ice Harbor, after the York, Penn.-based branch of Voith previously completed design and model testing with the Corps’ Hydroelectric Design Center and the Walla Walla District for Ice Harbor’s Kaplan runners in December 2014.

The three entities also 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.
