If this bill were to become law, it 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, during the integrated resource planning process, the ACC would be mandated to 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 insertion emphasizes the need for year-round reliability rather than seasonal considerations.

Additionally, the bill would require 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 change replaces the previous requirement for equally dispatchable load-following generation, thus broadening the criteria for reliability in electric generation. Overall, the bill aims to enhance the reliability and adequacy of electric service in Arizona.
