PINNACLE WEST REPORTS LOWER SECOND QUARTER RESULTS

PHOENIX — Pinnacle West Capital Corporation (NYSE: PNW) today reported lower consolidated net income for the quarter ended June 30, 2007, of $79.0 million, or $0.78 per diluted share of common stock. This result compares with net income of $112.2 million, or $1.13 per diluted share, for the same quarter a year ago.

The lower quarterly results were principally driven by lower earnings at Arizona Public Service (APS) as a result of an $8 million after-tax regulatory disallowance, milder weather, and the absence of $7 million of income tax credits recorded in 2006.

“The exceptional population growth in our service territory drives an ever-increasing demand for electricity,” said Pinnacle West Chairman Bill Post. “Going forward, we need to continue making substantial investments in infrastructure and long-term resources, while working with regulators to achieve timely and constructive regulatory treatment.”

For the second quarter of 2007, APS reported lower net income of $75.1 million, compared with net income of $93.8 million for the same period a year ago. Operationally, the 2007 quarter reflected significantly improved performance at the Palo Verde Nuclear Generating Station, which increased its output by 54 percent compared with the same quarter a year ago.

SunCor Development Co., Pinnacle West’s real estate subsidiary, reported net income of $0.3 million, compared with $9.6 million in the 2006 second quarter, primarily due to decreased sales of residential property.
