Electric Power Usage
Southwest Water Authority (SWA) purchases power from the federal government through the Department of Energy for the main transmission pumping and treatment facilities throughout the Project. These expenses are identified as Western Area Power Administration (WAPA) costs. Local utility companies distribute the power to each location. These expenses are identified as wheeling costs. SWA pays for wheeling the power to the local utility companies.
WAPA belongs to the Southwest Power Pool (SSP) and MDU belongs to Midcontinent Independent System Operator (MISO). Beginning January 1, 2017, SWA was required to join MISO after MDU joined to wheel the federal power. SWA now pays a MISO tariff at various locations including the WTP’s in Dickinson and the Beach, Bucyrus, Burt, Dodge, Finished Water, Jung Lake, Ray Christensen, Scranton and Richardton Pump Stations. Other power costs include locations system-wide which are considered small power users.
The chart on the right and the graph below illustrates the history of power costs at these locations:
