HB 3917 requires public utilities providing electricity to large data centers (defined as facilities using 50+ megawatts monthly) to file new tariff schedules with Oklahoma's Corporation Commission. These tariffs must include a peak-demand surcharge specifically for large data center customers. All surcharge revenue collected by utilities must be transferred to the newly created "Grid Modernization Revolving Fund" in the state treasury. The fund, managed by the Corporation Commission, will finance electric grid modernization projects, with the bill taking effect November 1, 2026.
