Welcome to Arizona RUCO
The Residential Utility Consumer Office (RUCO) was established by the Arizona Legislature in 1983 to represent the interests of residential utility ratepayers in rate-related proceedings involving public service corporations before the Arizona Corporation Commission (ACC). RUCO accomplishes this charge primarily through a staff of financial analysts and attorneys. RUCO participates in a number of policy matters that also affects the rates paid and services received by residential ratepayers.
