Greenberry Awarded $21.7 Million Project to Overhaul Grand Coulee Dam's Pump Generating Plant

Greenberry has won a $21.7 million contract from the U. S. Bureau of Reclamation to replace the reverse-flow gates at the John W. Keys III Pump Generating Plant, a feature of the Grand Coulee Power Complex in Grand Coulee, Washington.

"The Keys plant provides renewable hydropower and water for irrigation, supporting numerous jobs and significant economic vitality in the region," said Alan Mikkelsen, the Bureau’s acting commissioner. "Building major infrastructure such as this is one thing – making sure it runs at peak efficiency is a top priority. We are making this significant investment in one of the key projects in our portfolio as part of this administration’s focus on infrastructure renewal and repair across America. This project will help ensure the Keys plant continues to effectively support the 680,000 acres of farmland that depend on it for irrigation."

The principal components of work include replacement and rehabilitation of reverse-flow gates for pump units 1 through 6 and pump generator units 7 through 12. This includes work on the stems, hoists, hydraulic power units and controls, and exposed bypass piping. Construction activities will be conducted on two units per year. The work is scheduled to begin next spring and be completed in 2024.

Grand Coulee Dam, completed in 1941, is a multi-purpose facility that forms the hub of Reclamation’s Columbia Basin Project. The Keys Pump Generating Plant, located adjacent to Grand Coulee Dam, provides irrigation water to approximately 1,060 square miles of farmland in the Columbia Basin in central Washington.

The Bureau of Reclamation is the largest wholesale water supplier in the United States and the second largest producer of hydroelectric power. Its facilities also provide substantial flood control, recreation, and fish and wildlife benefits. Visit the Bureau’s website here.
