large load customers; energy costs

SB 1380 requires large electricity consumers in Arizona to pay directly for the energy costs (including fuel, generation, and transmission) tied to their own usage, rather than having those costs shared with other customers. It defines "large load customers" as entities using at least 50 megawatts during peak demand, specifically including data centers, cryptocurrency mining operations, industrial facilities, manufacturing plants, hydrogen production sites, and large buildings. The bill prohibits these large customers from passing their energy costs to other public power or public service corporation customers. This applies to both public power entities (like municipal utilities) and public service corporations (like investor-owned utilities). The law aims to allocate energy costs more directly to the users responsible for high demand.
