The air conditioner at Jim and Julie Powell's house has been fending off the 100-degree summertime heat for two decades — ever since they came to the Sun City retirement community just west of Phoenix.
"It's been a workhorse," Julie says. "It's probably 20 years old, but it does the job."
Inside, Jim leafs through their summer bills from the power company Arizona Public Service, or APS. He counts: "$183, $262, $250."
Steep, but predictable. Ever since he's heard about a new fee, though, he's begun to worry.
