New data centers, cryptocurrency-mining operations, and artificial-intelligence computing facilities that add at least 75 megawatts of electric load per facility or in aggregate behind one interconnection after July 1, 2026, are subject to large-load-customer requirements. Residential, commercial, agricultural, and industrial ratepayers, and entities building behind-the-meter generation, are excluded.

Electric utilities must obtain Oklahoma Corporation Commission approval for tariffs, contracts, or other rate arrangements serving qualifying data-center loads before service is provided or expanded.

Qualifying data centers must pay the costs attributable to serving their loads, including generation, transmission, distribution, interconnection, and other infrastructure costs, rather than shifting those costs to other ratepayers.

Electric suppliers must establish separate service terms and tariffs for qualifying large-load customers, including credit requirements and other measures to recover allocated costs and protect against unrecovered costs if the customer leaves or materially reduces its load.

A large-load customer must agree to a service term of at least 10 years, except that a public power utility using tax-exempt municipal financing may use the lesser of 10 years or the applicable Internal Revenue Service guideline.

A large-load customer or party acting for it that purchases land outside an industrial development park or municipality must, within 60 days, notify the Oklahoma Corporation Commission, county commissioners, and abutting property owners by certified mail with return receipt requested, and submit supporting materials including a plat, adjacent-owner identification, copies of the notices, and the Oklahoma Data Center Attestation. Failure to provide the notice carries a $1,500-per-day administrative penalty per violation.

Large-load customers must submit additional documentation, including the Oklahoma Data Center Attestation, before beginning operations.

Facilities that add less than 75 megawatts of electric load per facility, or in aggregate behind a single point of interconnection, are excluded from the Act’s large-load-customer classification and related requirements.

Entities that build generation for behind-the-meter projects are excluded from the large-load-customer classification and related requirements.

Electric utilities may enter into Corporation Commission-approved special service agreements with qualifying data-center customers covering rates, charges, and service terms.

Special service agreements may include long-term commitments, minimum payment obligations, or financial assurance, supporting utility investment in generation, transmission, distribution, interconnection, and system upgrades needed to serve a data center.

Qualifying data centers must pay the costs associated with serving their load, including necessary generation, transmission, distribution, interconnection, and system-upgrade costs, rather than shifting those costs to other ratepayers.

Electric suppliers must establish separate terms, conditions, and tariffs for large-load customers, including provisions to recover costs directly incurred to serve a customer that later leaves the system or materially reduces its load.

Large-load customers generally must receive electric service for at least ten years, providing long-term service certainty; for public power utilities using tax-exempt municipal financing, the term may be limited to the lesser of ten years or the applicable IRS guideline.

The large-load service requirements apply to all retail electric suppliers serving Oklahoma load, including investor-owned utilities, electric cooperatives, municipal electric utilities, and public power utilities.
