Oklahoma at a glance
Oklahoma is a major wind producer with cheap in-state natural gas, a combination that keeps rates well below the national average. Retail service is regulated. Summers are hot and long, making cooling the dominant load, while winters are mild enough that heating demand is secondary. Severe weather restoration costs are a recurring feature of rate cases.
