The Bureau of Reclamation awarded a $5 million contract to furnish and install unit circuit breakers at the 428-MW Hungry Horse hydroelectric project, on the south fork of Montana's Flathead River.
Gardner Zemke Co., Albuquerque, N.M., received the contract in December to remove, dispose of, and replace circuit breakers for four main units. It is to install four unit breakers, grounding switches, control wiring on boards, and new terminal boxes.
Work is expected to start in September. It is to be completed in January 2010.
Gardner Zemke performed similar tasks at the project under terms of an earlier contract, which involved replacement of two station service breakers. (HNN 8/22/07) BuRec said it considers the work vital to maintaining efficiency and safe operation of the power plant. (HNN 10/14/08)
Hungry Horse features a 564-foot-tall concrete dam completed in 1953 and a powerhouse with four units uprated and overhauled between 1990 and 1993. It is a multi-purpose project, providing for hydroelectric generation, flood control, and year-round recreation.
