Should utilities be allowed to charge extra fees to homeowners with rooftop solar?
The Arizona Court of Appeals rejected Arizona Public Service's second attempt to revive a monthly fee on rooftop solar customers. The utility intends to ask the Arizona Supreme Court to review the case.
Why it matters
The ruling determines whether utilities can impose a dedicated charge on rooftop solar households in Arizona, a question that affects how electricity costs are allocated between solar and non-solar customers. The outcome could shape future rate decisions by the Arizona Corporation Commission.
The Arizona Corporation Commission's 2024 rate increase allowed Arizona Public Service to add $2 to $3 per month, or $24 to $36 per year, to bills for rooftop solar customers. The dispute covers only this added charge, and it remains unclear how the Supreme Court will respond to the utility's planned appeal.
The players
Arizona Public Service
Arizona Public Service is the state's largest electric utility, serving a large share of Arizona households and businesses.
Arizona Corporation Commission
The Arizona Corporation Commission is the state body that regulates utility rates and approved the 2024 rate increase including the solar charge.
Arizona Court of Appeals
The Arizona Court of Appeals is the intermediate state appellate court that twice blocked the solar fee on procedural and evidentiary grounds.
The details
The Court of Appeals found APS had not shown that solar customers drove up costs and faulted regulators for approving the charge without letting opponents challenge it first. APS argues that supplying power when panels fail or underproduce creates extra costs that the fee was meant to cover.
Timeline
In 2024, the Arizona Corporation Commission approved the solar customer rate increase.
In December 2024, a rehearing was held where pro-solar groups presented their position.
In June, the appeals court blocked the solar charge.
On November 4, 2026, the Court of Appeals rejected APS's second attempt to revive the fee.
Utility Context
The fight over the rooftop solar charge follows the Arizona Corporation Commission's earlier moves to reshape rooftop solar compensation and grid-access fees for residential customers. The court rulings add a procedural limit on how quickly regulators can impose such charges without full public challenge.
If the fee survives, rooftop solar households in Arizona would pay an extra $24 to $36 per year on top of standard electricity bills. Blocking it keeps those households from paying that added charge while the appeal continues.
The takeaway
Rooftop solar owners should watch the Arizona Supreme Court docket, since a final ruling will determine whether the monthly charge applies to their bills.
What happens next
The Arizona Supreme Court will decide whether to review the case after APS files its petition.
