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 is a shift from the current law, which does not explicitly require year-round reliability.

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, ensuring safe and adequate service. This replaces the previous requirement for equally dispatchable load-following generation, thereby enhancing the reliability standards for electric generation in Arizona.
