U.S. to modernize controls for Hoover, Davis, Parker

The Bureau of Reclamation plans to seek proposals to modernize hydroelectric unit controls at the 2,078.8-MW Hoover, 255-MW Davis, and 120-MW Parker power plants, all on the Colorado River. The tentative due date is July 9.

BuRec’s Lower Colorado Region Office said it seeks design engineering and equipment to integrate the governor (speed/load) subsystem, excitation control subsystem, generator, step-up transformer relay protection subsystem, and unit control board replacement subsystem into a unified unit control system.

Work includes equipment for 32 units (26 large, two small, and four spares); and design engineering, including relay settings, for protection of 28 generators and 21 transformers. After installation of the equipment by the government, the contractor is to supervise testing of the unified unit control system and each subsystem during commissioning of the first eight units.

The Hoover power plant began service in 1936 as part of the Boulder Canyon project in Arizona and Nevada. It has 19 units. The Davis and Parker plants are part of the Parker-Davis project. Davis, which began service in 1951, is in Arizona. It has five units. Parker, which is in California, has four units and began operating in 1942.

The government said it intends to award a firm fixed-price contract with a performance period of three years. The solicitation (No. 06SP308064) will be issued on the Federal Business Opportunities Internet site: www.FedBizOpps.gov.
