AZ HB2949

Large data centers with peak demand of at least 100 megawatts must pay for all energy costs related to their operation, including fuel requirements, generation costs, and transmission costs

Energy costs incurred by large data centers cannot be passed on to other utility customers, protecting residential and business ratepayers from subsidizing data center operations

Applies to both public power entities and public service corporations regulated by the Arizona Corporation Commission

Defines "large data center" as any facility or campus of facilities used primarily for processing, storing, retrieving, or transmitting data with at least 100 megawatt peak demand

Creates a new Chapter 2 under Title 30 (Public Power Entities) and adds Section 40-107 to existing utility regulations to implement these requirements
