HB 3392 defines "large load customers" as commercial or industrial entities (like data centers, AI facilities, or advanced manufacturing sites) with a minimum 50-megawatt electricity demand. It requires the Oklahoma Corporation Commission to study how these customers impact grid infrastructure, system reliability, electricity rates, and cost allocation to ensure they fairly bear incremental service costs. The Commission must assess whether current rate structures shift costs to residential or smaller commercial customers and report findings by December 1, 2027. This bill directly affects electric utilities, large commercial customers meeting the definition, and all ratepayers through potential rate adjustments. The study aims to inform future regulatory decisions on infrastructure investments and cost fairness.
