The proposed bill would amend current statutes by requiring the Arizona Corporation Commission (ACC) to mandate that electric public service corporations submit an integrated resource plan for review and approval at least once every three years. This plan must include projections of energy demand for the next fifteen years, a summary of existing electric generation plants, identification of potential new plants, and analyses of capital and operating expenditures, reliability, and environmental impacts. Additionally, the bill stipulates that the ACC must obtain an independent evaluation of the submitted plans before approval, ensuring that the information provided by the public service corporations is verified and alternative analyses are considered.

Furthermore, the bill introduces specific requirements for the integrated resource plans, including the use of a ratepayer impact measure test to assess the financial implications of proposed generation plants and ownership structures. It also prohibits public service corporations from implementing compensation policies that conflict with their obligation to provide reliable service. The bill defines key terms related to the commission and electric generation plants, and clarifies that an approved integrated resource plan will serve as evidence of known conditions for the duration between submissions, unless new substantial evidence is presented.
