About electricity rates in Oklahoma

Oklahoma's electricity is supplied by regulated, vertically integrated utilities with no retail choice. Oklahoma Gas and Electric and Public Service Company of Oklahoma serve most urban customers, while electric cooperatives serve much of the rural state and some cities run municipal utilities. The Oklahoma Corporation Commission regulates the investor-owned utilities, and the state is part of the Southwest Power Pool.

Natural gas and wind supply the great majority of generation, and Oklahoma ranks among the leading wind-power states. Hot summers make air conditioning the main household load, and the largest utility has promoted time-of-use pricing programs for years to shift demand away from afternoon peaks. Winters are milder, though ice storms occasionally cause outages. Net metering is available for rooftop solar.
