Data centers; defining terms; requiring Corporation Commission provide for certain classification of service; effective date.

HB 3397 creates a special electricity pricing plan for large data centers using 20 megawatts or more of power. It requires Oklahoma's Corporation Commission to establish a separate rate classification for these facilities, with its own pricing plan that must fairly allocate costs and prevent shifting expenses to other electricity users. The bill mandates 10-year contracts between utilities and qualifying data centers, including minimum payment guarantees based on projected usage. This directly affects data centers meeting the 20MW threshold, with the law taking effect November 1, 2026.
