electric service providers; energy reliability

HB 2331 requires Arizona's public power entities and public service corporations to consider specific energy criteria when making planning and procurement decisions. The bill defines "clean energy" to include natural gas and nuclear power (if emissions meet pipeline-quality standards), "reliable energy" (requiring consistent power output and grid stability), and "affordable resource energy" (prioritizing stable costs and long-term savings). It mandates that these entities prioritize domestic fuel sources and minimize reliance on foreign materials for critical energy needs. The law directly affects how Arizona's energy providers evaluate and select power sources, emphasizing domestic availability, cost stability, and grid reliability.
