The proposed bill would amend current statutes by adding new requirements for the Arizona Corporation Commission (ACC) regarding public service corporations and their electric power grid management. Specifically, it would mandate that during the integrated resource planning process, the ACC must ensure that any changes made to maintain or improve the electric power grid are capable of producing sufficient electricity to provide safe, adequate, and reliable service throughout the year. This addition aims to enhance the reliability of electricity supply year-round.

Additionally, the bill stipulates that upon the retirement of an electric generation plant, the ACC must ensure that any replacement plant is capable of providing equal or greater reliability in electric generation, thereby ensuring safe and adequate service. This requirement replaces the previous language that focused on equally dispatchable load-following generation. Overall, the bill seeks to strengthen the regulatory framework governing electric utilities in Arizona by emphasizing reliability and adequacy in electricity generation and distribution.
