PINNACLE WEST REPORTS LOWER 2006 FOURTH QUARTER EARNINGS
APS Quarterly Results Down 30 Percent

PHOENIX — Pinnacle West Capital Corporation (NYSE: PNW) today reported lower net income for the quarter ended December 31, 2006, of $18.5 million, or $0.18 per diluted share of common stock. This result compares with net income of $21.3 million, or $0.22 per diluted share, for the same quarter a year ago.

In addition, the Company’s principal subsidiary, Arizona Public Service (APS), reported lower earnings of $12.9 million for the 2006 fourth quarter, compared with earnings of $18.3 million for the same period a year ago. Pinnacle West’s quarterly results also were impacted by lower results from its real estate subsidiary, SunCor Development Co, which reported income of $11.4 million, compared with $13.5 million in the 2005 fourth quarter.

Fourth-quarter earnings declined despite increased retail sales at APS due to customer growth of 4 percent, three times the national average, and income tax credits related to prior years. These positive factors were more than offset by higher operation and maintenance costs; increased depreciation and interest expense; lower results from the Company’s real estate operations, primarily due to timing of transactions during the year; and milder weather.

“Arizona is now the fastest-growing state in the nation, and our business reflects that fact,” said Chairman Bill Post, citing a record 44,000 new APS customers in 2006, the equivalent of a small city. “Looking ahead, growth will continue to dominate our operating environment, thus requiring innovation and investments in infrastructure to ensure we continue providing reliable, affordable energy.”

Post added that the effects of Arizona’s growth were evident throughout the company’s business in 2006, and employees met the challenge. Recognized by J.D. Power and Associates in its 2006 survey results for superior customer satisfaction, APS was rated the top investor-owned electric utility in the West by business customers and number two by residential customers.

In 2006, APS established a new system peak demand of 7,652 megawatts (MW) — 9.3 percent higher than the previous peak of 7,000 MW. APS met this peak, in large part, through the performance of its fossil-fueled power plants. Coal-fired plants set a company fleet record capacity factor of 87 percent, compared with the industry average of 72 percent. And, APS’ gas units produced their highest output ever of 7.3 million megawatt-hours.

Additionally, in a period of volatile energy costs, the Company continued its emphasis on cost containment and price stability. APS’ energy risk management efforts helped mitigate dramatic price swings of natural gas and their impact on customers. The Arizona Corporation Commission (ACC) also responded to this challenge. They approved changes to APS’ annual fuel adjustment, as well as APS’ request for interim rate relief, thus improving both current and future recovery of fuel-related costs.

For the year 2006 as a whole, Pinnacle West’s consolidated on-going earnings decreased 3.5 percent to $313.3 million, or $3.13 per diluted share. This result compares with 2005 on-going earnings of $324.5 million, or $3.35 per share.
