About Us

Upper Missouri was organized in 1957 to serve transmission needs of rural electric cooperatives in eastern Montana and western North Dakota. Upper Missouri provides service to 11 distribution cooperatives, 6 in eastern Montana and 5 in western North Dakota. The 11 member systems serve 74,834 meters to farms, ranches, homes, and businesses in 37 counties, representing over 54,762 square miles.

Upper Missouri sources power from two major suppliers, Western Area Power Administration (WAPA) and Basin Electric Power Cooperative. 96.69% of the power is sourced from Basin.

Upper Missouri has 241 metering points, serves as the Southwest Power Pool (SPP) meter agent and is a transmission owner in Midcontinent Independent System Operator (MISO).

Upper Missouri continues to have healthy sales growth due to the oil/gas development in the Bakken Oil Play. Upper Missouri became a 1470 MW system; sales growth in 2019 was 13.54% over 2018. Upper Missouri is projecting continued growth over the forecast period.

The headquarters facility for Upper Missouri is located in Sidney, Montana which is the county seat of Richland County. Sidney is also a major shopping center in Eastern Montana. Its exceptional medical facilities add to the areas status as a major retail center.  The area ranks at or near the top of all Montana counties in a number of agriculture and other production areas. It ranks second in oil production in the state and its livestock center is ranked sixth. The area has one of the lowest unemployment rates in the nation due to the current surge in crude-oil production as companies scramble to attract workers to keep pace with the oil production. The area also offers great recreational opportunities to relax in the “great outdoors” with many activities such as hunting, fishing, camping, hiking, golf, and boating.
