APS heightens security at Palo Verde, other facilities as precaution

PHOENIX, Ariz., Sept. 11, 2001 — Palo Verde Nuclear Generating Station officials this morning announced that they have increased security at the facility as a precautionary action in light of today’s tragic events.

Employees not required for plant operations were allowed to go home.

All three 1,270-megawatt units are operating safely at full power. All other company plants are operating as needed.

Security at other major APS facilities has been increased as well. Certain APS operations are being managed at backup facilities.

APS, which operates Palo Verde on behalf of the station’s six other owners, is Arizona’s largest and longest-serving electric utility and serves more than 857,000 customers in 11 of the state’s 15 counties. APS, with headquarters in Phoenix, is the largest subsidiary of Pinnacle West Capital Corporation.
