Natural Gas and Oil

We create electricity from coal, hydroelectric, natural gas, oil, solar, and wind facilities. We also purchase electricity from the Midcontinent Independent System Operator, or MISO, energy market when buying it is more economical than generating it ourselves. This mix ensures reliable, low-cost, and increasingly clean electricity 24 hours a day, 7 days a week.
