Palo Verde Unit 2 Sets Operational Run Record
PHOENIX, Oct 11, 2012 -- BUSINESS WIRE
Palo Verde Nuclear Generating Station's Unit 2 recorded the
best performance in plant history beginning with its last
refueling outage in spring 2011 to the current scheduled
maintenance and refueling outage, which commenced over the
weekend. The 1,340-megawatt unit operated for a plant-record 518
consecutive days, producing enough electricity over that time to
equal the production of almost three Hoover Dams.
"Palo Verde provides a reliable supply of low-cost
electricity which--particularly through the hot Arizona
summers--is essential to our customers," said Randy Edington,
Executive Vice President and Chief Nuclear Officer for Arizona
Public Service Co., the operator and largest owner of Palo
Verde.
The previous Palo Verde record for consecutive days on-line,
also held by Unit 2, was 515, completed in 1999. Unit 1 and 3's
longest consecutive runs are 502 and 509 days, respectively.
Palo Verde's three units are on an 18-month refueling cycle,
with two refueling outages scheduled each year - one in the
spring and another in the fall. About a third of the nuclear
fuel is replaced during each planned outage. Nuclear power
plants provide "base load" energy which means these plants
operate at all times whenever they are available. This is
because of their low production cost and stable output of
electricity.
In the year and a half since its previous refueling, Unit 2
has consistently operated at full capacity, generating vital
electricity for millions of customers across the Southwest.
"When we operate the units efficiently over an 18-month
cycle, we get exceptional value from the nuclear fuel that is
loaded in the reactor," added Edington. "In this case, we were
able to derive all the expected energy from the fuel in Unit 2,
which is of tremendous benefit to our customers and the
customers of the other Palo Verde owners."
Palo Verde is the largest energy producer in the United
States. Its three units can generate more than 4 million
kilowatts of safe, clean, reliable, low-cost electricity every
hour - enough to serve about 4 million people. Over the quarter
century of operation, it has surpassed 30 billion kilowatt hours
seven times, including a national record 31.3 billion kilowatt
hours in 2011. This is a level of production that no other U.S.
generating station has approached.
In addition to the energy produced, Palo Verde has an
estimated annual economic impact of $1.8 billion in Arizona
through taxes, salaries, purchases of materials and services,
and more.
"These accomplishments demonstrate our vision and commitment
to SAFELY and efficiently generate electricity for the long
term," said Edington.
Palo Verde is operated by APS and jointly owned by APS, Salt
River Project, Southern California Edison Co., El Paso Electric
Co., Public Service Co. of New Mexico, Southern California
Public Power Authority and the Los Angeles Department of Water &
Power.
APS, Arizona's largest and longest-serving electricity
utility, serves more than 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).
