APS has asked the Arizona Court of Appeals to reverse the ACC’s cost recovery disallowance and vacate the return on equity decision, as well as a 20-basis point penalty that regulators imposed for customer service issues.
In 2020, an ACC staff consultant’s report concluded the utility failed to conform to best practices, and among other issues, the company’s call center performance was below average.
But the utility told the judge that if the November decision stands, it will “drive up the cost of capital and debt for all Arizona [public service corporations]; chill PSC investments critical to statewide economic growth; increase utility prices for every citizen and business in Arizona; and threaten the future reliability of the state’s electric grid, natural gas and water delivery, and other utility services.”
