Arizona's major electric utilities are telling state regulators they're positioned to handle the upcoming summer heat and the season's demand on their systems.
The Arizona Corporation Commission on Thursday heard presentations from Arizona Public Service Co., Tucson Electric Power, the Salt River Project and other utilities about their preparedness for the upcoming summer.
APS is the state's largest electric utility, serving nearly 1.2 million customers in 11 counties.
The Phoenix-based company says its customers last summer experienced the most outages related to wind, rain and lightning in five years and that last August was the second hottest August on record.
But APS says it drew the necessary lessons and has built what it called "a stronger, faster, smarter" grid that means the company is well prepared heading into the summer.
