About electricity rates in Wyoming
Wyoming is served by regulated, vertically integrated utilities with no retail choice. Rocky Mountain Power serves most customers, Black Hills Energy covers Cheyenne, Montana-Dakota Utilities serves the northeast, and rural electric cooperatives cover vast stretches of the sparsely populated state. The Wyoming Public Service Commission regulates the investor-owned utilities.
Coal mined in the Powder River Basin has long dominated generation, and strong, steady winds have brought large wind farms; the state produces far more electricity than its small population uses and exports most of it. Winters are long, cold and windy, with most homes heating with natural gas, while the high elevation keeps summer cooling needs small. Net metering is available for small rooftop systems.
