Arizona Public Service Company

  • Overview

Arizona Public Service is a grand provider of energy in the Grand Canyon state. Arizona Public Service, a subsidiary of Pinnacle West Capital, distributes power to about 1.1 million customers in 11 of 15 Arizona counties, making it the largest electric utility in the state. It operates more than 5,900 miles of transmission lines and more than 28,930 miles of distribution lines; it generates 6,370 MW of capacity, mainly from fossil-fueled and nuclear power plants. Arizona Public Service also purchases power from other suppliers to supplement its company-owned generation capacity.

Financial Performance

Arizona Public Service accounted for all but $8.3 million of parent Pinnacle West's revenues in 2012.

In 2012 the company’s revenues grew by 2% due to rates settlement and higher retail transmission revenues.

Arizona Public Service’s net income increased by 17% in 2012 as the result of increased net sales and lower interest expenses.


Arizona Public Service is pushing conservation and the use of renewable energy in order to meet regulations requiring lower carbon emissions from power plants. As part of an ongoing commitment to ramp up renewable energy plants, the company helped to build one of the world's largest solar facilities (a 250-MW concentrating solar power plant) 70 miles southwest of Phoenix, near Gila Bend, Arizona, which came online in 2013. In 2010 Arizona Public Service entered a long-term power purchase with a unit of NextEra Energy Resources, to buy power from the 99-MW Perrin Ranch Wind Energy Center, Arizona's largest wind project, which became fully operational in 2012.

In 2012 the company's renewable energy projects (including biomass, geothermal, solar, and wind) had a generating capacity of more than 440 MW, or enough power to serve 108,500 customers.


The company is an operating unit of Pinnacle West.
