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 more than 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 6,340 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.
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 is helping 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, due to come 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, which, when fully operational in 2012, will be Arizona's largest wind project.
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.
Arizona Public Service accounted for all but $4 million of Pinnacle West's revenues in 2011. Higher rates and increased demand lifted the utility's revenues by almost 2% in 2011. It also posted a slightly higher net income that year due to lower fuel and purchased power costs and an increase in income taxes.
Arizona Public Service was established in 1920.
