Solar Power Industry Names Brandt `Utility CEO of the Year`

ANAHEIM, Calif.--(Business Wire)--
APS Chief Executive Officer Don Brandt today was named the Solar Electric Power
Association`s "Utility CEO of the Year" at the Solar Power International 2009
conference in Anaheim, Calif.

Brandt was recognized for his efforts in helping Arizona become the "solar
capital of the world." Under his leadership, APS solar initiatives include:
Solana, the world`s largest solar plant, which will be built in the Arizona
desert; a commitment to invest $500 million to develop 100 megawatts of
utility-owned solar generation; a pilot project to provide solar panels on
customer homes with no up-front cost; and a partnership with the National Park
Service to power the Grand Canyon Visitors Center with solar panels.

"Don Brandt has positioned APS to take full advantage of Arizona`s most abundant
natural resource, the sun. APS is creating viable business models around solar
energy that not only push the envelope but also push our industry forward," said
SEPA Executive Director Julia Hamm.

"We very much appreciate this award. It reinforces our vision: we want the Grand
Canyon State to become the Solar State," said Brandt.

APS has seen its renewable energy portfolio grow from less than one megawatt in
2001 to more than 235 megawatts today, enough to power 59,000 Arizona homes. APS
has also published a resource plan that proposes renewable and solar energy meet
half of all new customer demand during that time frame.

In 2006 the Arizona Corporation Commission set a Renewable Energy Standard of 15
percent by 2025.

Don Brandt has more than 25 years experience in the electric power industry. He
is also Chairman of the Board, President and Chief Executive Officer of APS
parent Pinnacle West Capital Corp. Before joining Pinnacle West in December
2002, he served as Senior Vice President and Chief Financial Officer at Ameren
Corporation, a St. Louis-based diversified energy services company.

Winners of SEPA`s "2009 Solar Business Achievement Awards" were selected in five
categories based upon their efforts to expand solar energy as an essential part
of the solution to the growing global energy crisis. Nominees for the awards
included utility executives, electric utilities and solar companies from SEPA`s
member companies around the world.

APS, Arizona's largest and longest-serving electric utility, serves about 1.1
million customers in 11 of the state`s 15 counties. With headquarters in
Phoenix, APS is the principal subsidiary of Pinnacle West Capital Corp. (NYSE:
PNW).
