Arizona Public Service Company is the largest electric utility in Arizona, United States and the principal subsidiary of publicly traded S&P 500 member Pinnacle West Capital Corporation (: PNW), which in turn had been formerly named AZP Group, when Arizona Public Service reorganized as that holding company in 1985.

With 4,000 MW of generating capacity, APS serves more than one million customers in 11 counties throughout most of the state, but mainly concentrated in northern and central Arizona. APS is one of the two major suppliers of electricity to the Phoenix metropolitan area (the other being Salt River Project).

APS is regulated by the Arizona Corporation Commission (ACC), the state agency that, by mandate of Article 15, Section 2 of the state's constitution, regulates energy utilities in Arizona, with the notable exception of SRP, the rural electrical districts, and the City of Mesa electric utility serving Downtown Mesa and the immediate vicinity (with the rest of the city being served by SRP).

The holding company, Pinnacle West Capital, through its APS utility sells wholesale and retail power to the wider western United States and also provides energy-related services. Through another major subsidiary, Pinnacle West also developed and manages real estate in Arizona. Pinnacle West left the real estate business in 2010.

The utility company also operates three nuclear reactors. Its Palo Verde Nuclear Generating Station in Arizona, the largest nuclear plant in the U.S., came under scrutiny by the Nuclear Regulatory Commission in 2005 when operational problems began to cause prolonged outages.

In 1884, the Phoenix Light and Fuel Company was formed to provide electricity and heat to the people of the three-year-old town of Phoenix. It changed its name to Pacific Gas and Electric in 1906 and to Central Arizona Light and Power in 1920. Also in 1920, it paid a dividend, and continued the annual dividend without interruption for the next 69 years.
