Fuel choice in South Dakota

South Dakota's fuel choice is shaped by its geography. Natural gas utility service is available in Sioux Falls, Rapid City, Aberdeen, and along major corridors, but propane is extremely common across South Dakota's rural areas — the state has large areas of dispersed rural housing where natural gas doesn't reach, and propane tanks are standard on farms and rural homesteads.

For properties in Sioux Falls or Rapid City on natural gas, natural gas is generally the preferred generator fuel. For rural South Dakota, propane is often already available on site. See our natural gas vs. propane guide for the full tradeoff.

Weather and outage risk in South Dakota

South Dakota has some of the most severe and varied weather in the continental U.S.:

Winter blizzards and extreme cold are the defining outage risk. South Dakota's Great Plains location means no terrain barrier to Arctic air masses; temperatures of -20°F to -40°F (air temperature, not wind chill) are recorded in most winters. The combination of extreme cold, high winds, and heavy snow produces ground blizzards that make road travel and utility repair impossible for days. Outages during extreme cold events are not just inconvenient — they are dangerous.

The October 2013 Atlas Blizzard is the defining recent example: an early-season storm dropped 4 feet of heavy wet snow across western South Dakota, killed an estimated 75,000–100,000 cattle, and caused widespread power outages that lasted days to over a week in rural areas.

Tornadoes and severe thunderstorms — South Dakota's eastern plains see significant spring tornado risk, particularly in the May–June season. The Sioux Falls metro and surrounding eastern South Dakota farmland have experienced multiple significant tornado events.

Summer heat and drought — Extended heat waves in summer push the South Dakota grid toward capacity, particularly in Sioux Falls where cooling load is highest.
