OK HB3397

Oklahoma Corporation Commission must create a separate service classification with its own tariff schedule for "large energy use facilities" (data centers using 20+ megawatts under NAICS code 518210)

Tariff schedules must allocate costs proportionally to the large energy use class and mitigate risk of shifting costs to other retail electricity consumers

Electric companies must enter contracts of 10 years or longer with large energy use facilities, specifying service start dates and requiring minimum payment obligations based on projected usage

Contracts may include excess demand charges beyond standard tariff rates and must address potential service delays within the electric company's control

The exemption allowing parties to bypass the new service classification expires January 1, 2029; the act becomes effective November 1, 2026
