“No rate hikes! No rate hikes! No rate hikes!” Before packing two Arizona Corporation Commission hearing rooms for nearly four hours of public testimony, local advocacy groups and utility ratepayers gathered outside of the commission’s downtown Phoenix building on May 18 to protest Arizona Public Service’s proposed 14% rate increase. APS is the state’s largest electricity provider, serving 1.5 million residential and commercial customers. It is currently in the process of asking the commission, the state’s utility regulatory body, for its third rate increase in four years.
