Hyperscale data centers; Oklahoma Hyperscale Data Center Directory Act; Oklahoma Corporation Commission; directory; electrical utilities; water providers; effective date.

HB 3394 creates a public directory of large data centers in Oklahoma, requiring electric utilities and water providers to report annual electricity and water usage data to the Oklahoma Corporation Commission. The directory, updated yearly on the Commission's website, will include facility location, electricity use (in megawatt-hours), peak electrical demand, water usage (in gallons), and water source. This affects hyperscale data centers (defined as facilities over 50,000 sq ft with at least 10,000 MWh annual electricity use) and the utilities/water providers serving them. The law protects sensitive infrastructure details while making aggregated data publicly accessible, with penalties for non-compliance.
