Customers of Arizona’s largest utility are pushing back against its proposed rate hike.

On Wednesday, the Arizona Corporation Commission held one of several public hearings on Arizona Public Service's rate case.

Earlier this month, APS walked back an increase of $11 a month for the average customer and what would have been a mandatory demand charge for most residential customers. That would be a new fee based on the one-hour window of the month during peak when a customer uses the most power.

Instead, the utility came to a tentative agreement with more than two dozen stakeholders that would amount to only about a $6 increase for the average customer and the option to use a demand charge.

But these changes don’t go far enough for many who showed up for the public hearing.

Rich Stevens, a retiree who lives in Prescott, says the monthly fixed charge on his bill would nearly double and that is "unreasonable and wrong."

"It lessens my ability to control my bill when I have to make many choices in the course of a month on how I have to pay for the things I need,” he said.

While it's true those with a monthly charge of about $8 will see an increase, Stefanie Layton of APS says that’s only one part of a total bill for a certain group of customers.

“Many of our options, six out of the seven rate options, would offer a basic service charge decrease for more than half of our customer today,” Layton said.

The Corporation Commission will be reviewing the proposed APS settlement in the coming months and is expected to make a final decision in the summer.
