PHOENIX -- (Business Wire)
The 2015 Arizona monsoon season has been merciless…and it’s not over
yet. Dark clouds roll in, with sparks of heat lightning that fill the
skies. Hurricane-strength winds topple large trees, damage
infrastructure and create microbursts that destroy front yards and leave
neighborhoods with days of cleanup. Overall, the 2015 storm season has
been one of the most damaging for APS in recent years.

APS crews replace a wooden pole splintered by an intense storm last week. Within the last three weeks, five powerful storms have hammered the Phoenix metro area.

Five
powerful storms within the past three weeks have hammered the
Phoenix metro area. Those storms, with winds upwards of 90 mph, have
caused significant damage since late August, leaving
hundreds of thousands of customers without electricity and knocking
down 485 power poles – an 81 percent increase from 2014.
“We track the weather on a daily basis, so we know what’s rolling in and
can prepare our employees to mobilize quickly if a storm hits,” said Ted
Geisler, Director of Transmission Operations and Maintenance for APS.
“There have been several occasions this summer when I’ve walked out of
our building in downtown Phoenix and it felt like walking into a
hurricane. The winds were unbelievably strong; we knew immediately that
our crews would be faced with the challenging task of rebuilding parts
of our system.”
On August 27, more than 50 poles were destroyed in the West Valley.
Three days later, on August 30, another powerful storm blew in the same
general area and knocked down another 50 poles. On August 31, 145 poles
were claimed by a powerful storm in Central Phoenix. Wood poles snapped
in half like toothpicks; steel poles with 19-inch diameters were bent in
half. The devastating winds continued during this most recent storm on September
14, bringing 12 poles down at Indian School and 16th
Street – with pole after pole lying in a canal and across the
intersection.
“In 2014, we lost 268 poles due to storm conditions. This year, that
number is already up to 485, and the season isn’t over yet,” said
Geisler. “We’ve been managing
Arizona monsoon season for more than 125 years. Each season brings
its own set of challenges. This year, 2015 has been the summer of wind.”
With each storm, the majority of customers were restored within 24
hours. Preparing for summer storms is something APS does all year; crews
continually train to be able to face any issue in the field, and
equipment and supplies must be maintained and readily accessible. APS
first responders are ready to replace power poles, wire, transformers
and other equipment, as needed, to restore power.
In the most recent J.D. Power customer satisfaction survey, APS ranks 2nd
overall in power quality and reliability.
“We know how inconvenient and uncomfortable a service disruption can be
– especially during an Arizona summer when temperatures rarely dip below
100 degrees,” said Geisler. “Our goal is to keep the lights on. Our
linemen, construction and vegetation management crews work around the
clock – including through the night – to restore power when these
powerful monsoons strike. Our commitment to public service is something
we take very seriously, and we want our customers to know that when the
lights go out, we’re working to restore power and make our system whole.”
Power pole inspection and replacement happens year-round. APS inspects
33,000 poles each year to check for damage or weakening areas of the
grid. These pole inspections occur in addition to line inspections; APS
inspects every line in its system every year. During these inspections,
about 1 to 2 percent of the poles are proactively replaced to ensure
customers continue to receive the reliable electricity they have come to
expect from APS. A typical pole has a life of 35 to 40 years, and APS
currently has more than 420,000 poles throughout its system. The total
number of poles that APS has replaced this summer – including poles
destroyed by storms – is more than 2,600.
When poles are replaced, APS takes every opportunity to harden the grid
by replacing wood poles with steel. The placement of a wood pole versus
a steel pole is highly dependent on the location and soil condition. For
example, if a pole is in an area that is not easily accessible by bucket
truck, a wood pole is required so that linemen can perform needed work
on the pole by climbing it (since you can’t climb steel poles).
APS,
Arizona’s largest and longest-serving electricity utility, serves nearly
1.2 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).
