Arizona Attorney General Kris Mayes spoke to around 200 APS customers Tuesday night at a town hall in north Phoenix centered around the proposed APS utility rate increase. The proposed rate would increase APS total revenue by nearly $580 million or 14% overall. Under the new rate structure, homeowners could pay 16% more, depending on their plan. Solar customers face a doubling of their fees and data centers could have a 45 percent jump.
