RUCO is an advocate of residential ratepayer interests before the Arizona Corporation Commission. We have been actively engaged in complex rate case litigations and additional line-siting and corporate certification applications, and played central policy-level roles in successfully advocating residential consumer positions that resulted in acceptance by the Commissioners in their decisions. There is occasionally a redundant and repetitive nature of the case summaries compiled in these Annual Reports. Each summary intentionally has been written so that any party can read its contents without the need for additional context found elsewhere in the document, making each summary easy and understandable as a stand-alone guide to the particular case. It is understood that RUCO is no longer required to assemble Annual Reports.

Mission: To exercise exclusive state regulatory authority over public service corporations (public utilities) in the public interest; to grant corporate status and maintain public records; to ensure the integrity of the securities marketplace; and to foster the safe operation of railroads and gas pipelines in Arizona. The Commission oversees the process of incorporating or registering a company to do business in the state, registers and oversees securities offerings and dealers and enforces railroad and pipeline safety. They adopt rules and regulations thereby functioning in a legislative capacity; and they also act in a judicial capacity sitting as a tribunal and making decisions in contested matters.
