Pinnacle West Capital Names New General Counsel

June 17, 2009

Pinnacle West Capital Corporation (NYSE: PNW) today announced the appointment of David P. Falck as Executive Vice President, General Counsel and Secretary of Pinnacle West and Arizona Public Service Company.

With more than 20 years of experience as a legal advisor to the energy industry, Falck comes to Pinnacle West from New Jersey-based Public Service Enterprise Group Inc. (PSEG), a diversified energy company that owns one of the nation's largest electric utilities. While at PSEG, Falck held the position of Senior Vice President - Law, with responsibilities for the Law Department and the Office of the Corporate Secretary.

Falck will succeed retiring Senior Vice President, General Counsel and Secretary Nancy Loftin, who joined the company in 1985. The changes will take effect late-July 2009.

"Nancy has helped steer Pinnacle West and APS through a variety of challenges for more than two decades, and I know I speak for everyone at the Company and on the Board when I say she will be missed as a professional, a peer, a counselor and a friend," said Chairman and Chief Executive Officer Don Brandt.

Prior to joining the senior management team at PSEG, Falck was a partner and member of the Managing Board of Pillsbury Winthrop Shaw Pittman LLP, New York, an 800-lawyer firm with offices in the U.S. and abroad. He joined Winthrop, Stimson, Putnam & Roberts, a predecessor firm, in 1978.

"David brings experience from a diversified energy company that rivals ours in setting benchmarks in many areas of performance," said Brandt. "Additionally, he has a well-earned reputation as a real expert in energy and utility law developed over the course of decades of intensive, first-tier practice."
 
Falck holds a Doctor of Laws degree from Washington & Lee University School of Law in Virginia, and an undergraduate degree from Colgate University in New York.

Pinnacle West is a Phoenix-based company with consolidated assets of about $11 billion. Through its subsidiaries, the Company generates, sells and delivers electricity and sells energy-related products and services to retail and wholesale customers in the western United States. It also develops residential, commercial, and industrial real estate projects.
