PHOENIX – When the sun wasn’t being
obscured by the moon this summer, it produced enough heat for customers to
break Arizona energy records, even as new technologies worked to increase
efficiency and reliability across the Grand Canyon State.
and large batteries came onto the scene in Arizona in 2017, delivering
increased reliability to millions of APS customers. This reliability was
reinforced by a new operating system – the Advanced Distribution Management
System (ADMS) – adopted by APS to increase grid resiliency and shorten outage
times for customers. In addition, APS rebuilt parts of the grid after the
summer wildfire season, and ensured power to customers during a historic solar
eclipse. While the eclipse cut solar output by nearly 50 percent at its height,
APS was fully prepared and relied on its diverse resource mix, including carbon-free nuclear power from Palo
Verde Generating Station, advanced technologies and quick-start natural
gas-fired plants, to provide power to customers.
past a microgrid or energy storage unit, many customers wouldn’t look twice,
but those technologies are playing an increasingly important role in delivering
efficient energy on the hottest days of the year,” said Jacob Tetlow,
APS Vice President of
Transmission and Distribution Operations.
June 2017 was the third hottest June ever
recorded in the Phoenix metro area, with June 20 topping out at 119 degrees.
While hot summers are nothing new to Arizona, on that day APS customers set an
all-time record peak demand of 7,367 megawatts, breaking the previous record of
7,236 MW set in 2006. To meet this demand, APS relied on a diverse mix of
traditional resources, as well as advanced technologies.
customers’ needs are changing, technology is progressing and APS is ready for
both,” said Tetlow. “Thoughtfully implementing these technologies makes our
grid smarter, faster and stronger.”
future looked even brighter this summer as APS announced plans to break ground
on battery storage units in Punkin Center, AZ. The batteries will take the
place of rebuilding 20 miles of power lines, providing even greater reliability
to the growing community. The project is one of the first of its kind in the
nation and is slated to be operational by next summer.
also experienced its first summer with its Advanced Distribution Management
System or ADMS. ADMS is an advanced operating system that provides grid
operators increased visibility and accessibility to power lines across the
state. The ability to remotely control lines played an important role in APS’s
response to the Goodwin fire in June. APS crews worked long hours, coordinating
with state and local officials, to de-energize power lines and help ensure the
safety of both first responders and local residents. After fire crews
from across the country extinguished the blaze, APS quickly and safely
reenergized lines as residents returned to their homes and businesses.
the summer of 2017 will surely go down in the history books, the technology
tested will lead the way to Arizona’s energy future.
APS serves about 2.7 million people in 11 of
Arizona’s 15 counties, and is the Southwest’s foremost producer of clean, safe
and reliable electricity. Using a balanced energy mix that is nearly 50 percent
carbon-free, APS has one of the country’s cleanest energy portfolios, including
both Palo Verde Generating Station and renewable energy. The company is also a
proven leader in introducing technology and services that offer customers
choice and control over their energy consumption. With headquarters in Phoenix,
APS is the principal subsidiary of Pinnacle West
Capital Corp. (NYSE: PNW).
