The Bureau of Reclamation has awarded a $27.5 million contract to Alstom of Littleton, Colo., to rebuild four of the eight hydroelectric power generation units at Glen Canyon Dam that have reached the end of their service life.

"For nearly 50 years, Glen Canyon Powerplant has generated renewable, hydroelectric power to help meet the electrical needs in the West," said Reclamation Commissioner Michael Connor. "The units being rebuilt under this contract have been in service for nearly 30 of those years. Replacing the generation units on schedule ensures continued reliability and optimal efficiency of the powerplant for the next 30-35 years as Reclamation supports the nation's all-of-the-above energy strategy."

The four units to be replaced will have improved generator components – known as 'stators' – made from solid copper bars, increasing reliability and extending the life of the units by up to 10 years. Once the work is completed, all eight of the powerplant's generators will have been rebuilt.

Work is scheduled to begin in the summer and continue through December 2016 with the process to rebuild each generator taking approximately seven months to complete. Only one generator will be rebuilt at a time which equates to 173 megawatt reduction in the total power plant capacity while each unit is off-line.

All power plant maintenance and replacement activities are scheduled in full coordination with the Western Area Power Administration which markets the power sold to municipalities, rural electric cooperatives, Native American tribes, and government agencies in Wyoming, Utah, Colorado, New Mexico, Arizona, Nebraska, and Nevada.

Glen Canyon Powerplant has a total capacity of 1,320 megawatts and annually produces approximately five billion kilowatt-hours of power to help sustain the electrical needs of about 5.8 million customers.
