Rehab Contract Awarded for Grand Coulee Project

The U.S. Bureau of Reclamation awarded Albuquerque, N.M.-based Gardner Zemke Co. a $26 million contract to replace six transformers at the Grand Coulee Dam project on the Columbia River, about 90 miles west of Spokane, Wash.

The current transformers have been in continuous service since 1975 and have been deemed unreliable and in deteriorating condition, Reclamation said.

In addition to furnishing and installing six new transformers, Gardner will remove and store/dispose the existing transformers. What’s more, the company will perform any modifications necessary to accommodate the installation and operation of the new transformers, Reclamation said.

The improvements “are needed to ensure continued operation and reliability to provide electrical power in the Pacific Northwest,” said Reclamation Commissioner Michael Connor. “The economic impact of interrupted public power generation would be substantial if these generating units are not repaired.”

Earlier this year, Reclamation awarded a $6 million contract to furnish and install three new transformers at Grand Coulee Dam Right Power Plant. (HydroWorld 3/23/09)
