APS 2012 Annual Report Download - page 4

In 2011 the employees of Arizona Public Service achieved new bests for electric reliability, customer
satisfaction, power generation and workplace safety.
In 2012 they did it again.
Despite a hot Arizona summer – there really isn’t any other kind – APS had the fewest outages (0.77 per
customer) in the company’s history. We are among the best in the nation at providing customers with
reliable electric service.
APS ranked third nationally among 55 large investor-owned utilities in the 2012 J.D. Power and Associates
survey of residential customer satisfaction, up from fourth last year. In a separate survey by Market
Strategies International, 94 percent of our large business customers expressed satisfaction with APS, with
68 percent indicating they were very satisfied.
Palo Verde Nuclear Generating Station, the nation’s largest nuclear power plant, produced 31.9 million
megawatt-hours of clean, low-cost power in 2012, the most ever by a U.S. power plant. Contributing to
this performance was the remarkable run of Palo Verde’s Unit 2, which set a site record of 518 days of
continuous operation before coming off-line for a planned refueling.
The largest single year of growth for our solar portfolio brought us to 1,090 megawatts of renewable
capacity in operation or under construction, and keeps us on track to achieve Arizona’s renewable energy
standard of 15 percent by 2025. Our fossil-fueled generating plants achieved operating performance
well above our 2012 targets.
We completed the renovation of our energy operations center, which combines state-of-the-art technology
with environmental features that earned the building LEED Silver certification – part of a commitment that
has put us on the Dow Jones North America Sustainability Index in all eight years of its existence.
