The proposed bill amends title 40 of the Arizona Revised Statutes by adding a new chapter related to residential power. It defines terms such as "Medical professional," "Reasonable payment arrangement," and "Utility." The bill prohibits utilities from disconnecting heating or air conditioning services under certain temperature conditions and requires utilities to offer reasonable payment arrangements to customers for outstanding balances.

Additionally, the bill prevents utilities from disconnecting service for customers with household incomes at or below 200% of the federal poverty guidelines who make minimum payments, as well as for households with elderly residents, pregnant women, young children, or individuals using life-support equipment. It also mandates a 30-day disconnection delay on receipt of notice from a medical professional, which can be extended for another 30 days. Utilities must inform customers of low-income assistance programs and payment assistance resources before disconnecting services.
