Desert Southwest Region

The Desert Southwest Region carries out WAPA’s mission to customers in Arizona, southern California, and southern Nevada. We sell more than 10.3 billion kilowatt-hours of federal hydroelectric power to cities and towns, rural electric cooperatives, federal and state agencies and irrigation districts. This is enough energy to provide electric service for a year, to more than two million homes.

Provided Services

WAPA’s Desert Southwest Region markets federal hydroelectric power to nearly 70 municipalities, cooperatives, federal and state agencies, and irrigation districts from power plants operated at Hoover, Parker, and Davis dams.

DSW also operates and maintains more than 40 substations and 3,100 miles (4,950 kilometers) of transmission lines to keep the system running reliably. Our partnerships with our customers allow us to help them quickly restore service to local residents after storms or other major system disturbances.
