Justia Utilities Law Opinion Summaries

Articles Posted in Arizona Supreme Court

Arizona Water Company (AWC), a utility company, sought a rate increase and proposed a step-increase mechanism that would allow the Arizona Corporation Commission to adjust rates between full rate cases. The rate increase mechanism, called the system improvements benefit (SIB), would allow AWC to petition for a rate increase between rate cases to help AWC recoup the cost of newly-completed infrastructure projects. The Commission approved the SIB mechanism with some modifications. The court of appeals vacated the Commission’s approval of the SIB mechanism, concluding that the SIB mechanism did not comply with the state Constitution’s mandate that “the Commission determine a public service corporation’s fair value when setting rates[.]” The Supreme Court vacated the court of appeals’ opinion and affirmed the Commission’s orders approving the SIB mechanism, holding that the SIB mechanism complied with the Constitution’s mandate that the Commission determine the fair value of a utility’s property when setting rates.
