HB 2788 requires Arizona electric utilities to submit comprehensive 15-year energy plans every three years, detailing projected demand, generation capacity, costs, and reliability. The bill mandates third-party reviews of these plans and requires analysis of carbon emissions across the full lifecycle of power plants, including manufacturing and decommissioning. Utilities must identify the lowest-cost option meeting reliability standards without prioritizing emissions goals, while analyzing both scenarios with and without available subsidies. It also prohibits utilities from basing employee compensation on metrics conflicting with providing safe, reliable, and affordable service.
