Fifty-Sixth Legislature, Second Regular Session
AMENDED
FACT SHEET FOR S.B. 1637
electric vehicle charging stations
Purpose
Prohibits the charges, rates, tolls and rental fees received by an electricity supplier for any
commodity or service from being used to invest in electric vehicle charging stations and allows
the charges, rates, tolls and rental fees received by an electricity supplier to be used for make-ready
infrastructure.
Background
The Arizona Corporation Commission (ACC) is established by the Arizona Constitution
with the authority to supervise and regulate public service corporations in Arizona. The ACC has
the power to: 1) prescribe classifications to be used by, and rates and charges to be made and
collected by, a public service corporation; 2) make rules, regulations and orders on the business
transactions of a public service corporation; 3) prescribe the forms of contracts and the systems of
accounting to be used by a public service corporation; and 4) make and enforce rules, regulations
and orders for the convenience, comfort, safety and health of the employees and patrons of a public
service corporation (Ariz. Const. art. 15, §§ 1; 2; and 3).
The ACC oversees the electric power industry in Arizona but does not have authority over
electric service provided by a city, municipality, irrigation district, electric district or utilities
operated by tribal authorities (ACC).
There is no anticipated fiscal impact to the state General Fund associated with this
legislation.
Provisions
1. Prohibits the charges, rates, tolls and rental fees received by an electricity supplier for any
commodity or service from being used to invest in electric vehicle charging stations and allows
the charges, rates, tolls and rental fees received by an electricity supplier to be used for make-
ready infrastructure.
2. Exempts, from the prohibition, an electric vehicle charging station that an electricity supplier
constructed, provided, owned, operated or maintained before the general effective date.
3. Allows an affiliate of an electricity supplier to provide, own, operate or maintain electric vehicle
charging stations. FACT SHEET – Amended
