Arizona's extra fees to solar power users has been struck down in state court.
After years in the courts, the Arizona Court of Appeals ruled in favor of Vote Solar, striking down the Arizona Corporation Commission’s (ACC) approval of discriminatory charges for customers of Arizona Public Service (APS) who have rooftop solar. In its decision, the Arizona Court of Appeals vacated the solar fees, ruling that they were imposed in an unfair manner that violated due process requirements.
APS, a regulated utility powering 1.4 million households and businesses in Arizona, first created the solar fees in its 2022 rate case, and they currently amount to roughly $2 to $3 in additional monthly charges for households with rooftop solar. Vote Solar filed an appeal in 2025 against the “grid access charge.”
APS has proposed to increase the fees to roughly $6 per month in its current rate case, which is under consideration at the ACC. Vote Solar, the Arizona Center for Law in the Public Interest (ACLPI) and Earthjustice are opposing the fee in that case as well.
This ruling is about not notifying the public, and not following their own rules, and not about the underlying merits of this fee.
I don't think that the fee will be reinstated, because the ruling requires proper procedure and advance public notice, and if they cannot sneak it in, public outrage would likely force the utility and the regulators to back down.
