U.S. awards transformer replacement contract for Grand Coulee hydropower project

The Bureau of Reclamation has awarded New Mexico-based Gardner Zemke Company a $12.3 million contract to replace 15 transformers in the Left and Right power plants of the 6,809-MW Grand Coulee hydroelectric project.

The 6,809-MW Grand Coulee hydropower project is located on the Columbia River, about 90 miles west of Spokane, Wash.

Under the current contract, the agency seeks replacement of transformers of units G1-G9, including furnishing and installing 15 single-phase, two-winding, 13.6-kilovolt-235-kV, 50-megavolt-ampere, water-cooled transformers and appurtenances in the Left and Right power plants.

Reclamation recently awarded American Governor Co. a contract to upgrade governors in the project's Third Power Plant. Reclamation has been recruiting contractors for various work to rehabilitate Grand Coulee, mainly in the Third Power Plant.
