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, the bill would require the ACC to ensure that any changes made to maintain or improve the electric power grid are capable of producing enough electricity to provide safe, adequate, and reliable service throughout the year. This is a shift from the current law, which does not explicitly mandate year-round reliability.

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 more reliable electric generation, thereby ensuring safe and adequate service. This replaces the previous requirement for equally dispatchable load-following generation, thus emphasizing reliability over specific generation characteristics. Overall, the bill aims to enhance the reliability and adequacy of electric service in Arizona.
