50-MW solar plus storage facility will serve APS customers during hot summer months
PHOENIX — Two homegrown leaders in renewable energy, Arizona
Public Service and First Solar (Nasdaq: FSLR), are bringing a first-of-its-kind
50-megawatt (MW) solar-fueled battery to the desert to provide clean power to
Arizonans on hot summer days. This project will make Arizona home to one of the
largest battery storage systems in the country. The innovative design models
how the future of solar and storage can work together to deliver power to
customers during peak hours.
Solar will build and operate this flagship facility that includes a 65-MW solar
field to charge the battery. APS has signed a 15-year power-purchase agreement
with First Solar that will enable APS to use the stored battery power when
energy use is at its peak later in the day.
pairing clean solar energy with advanced battery technology, First Solar and
APS will be able to store power when the sun is high in the sky and deliver it
to customers between 3 and 8 p.m. when the sun is on its way down, but energy
use is peaking. This means that APS customers can get more of their peak
power from solar.
want clean and reliable energy. This project adds to the more than one million
solar panels and three grid-scale batteries currently on APS’s system. Over the
next 15 years, APS plans to adopt more than 500 MW of additional battery
with an Arizona company such as First Solar to pair solar power with advanced
battery storage is good for our customers and continues our state’s national
leadership in clean energy innovation,” said Don Brandt, Chairman,
President and CEO of APS.
First Solar, the project represents the next step in solar energy.
Utility-scale solar is a clean energy resource, and the addition of battery
storage allows the power of the sun to be used in the evening when the energy
is needed most. This is a logical use of technology in a state that sees nearly
300 days of sunshine per year.
Solar has long been a global leader in the deployment of utility-scale solar,”
said Mark Widmar,
First Solar’s Chief Executive Officer. “Through this innovative project we are
excited to partner with APS to demonstrate the capabilities of solar coupled
with large-scale battery storage. Together, these technologies highlight the
significant role for solar in providing reliable, cost effective energy.”
project was developed in response to APS’s request for peaking capacity
resources to serve customers between the peak hours of 3 and 8 p.m. during the
hot summer months. APS has full use of the 50-MW battery and is able to
maximize hourly capacity until it is fully discharged. The facility is set to
begin service to customers in 2021 and will be built directly adjacent to the
existing APS Redhawk Power Plant in western Maricopa County.
has always been a state powered by the sun. Whether it is growing cotton and
citrus or an enviable climate, the sun is at the center of Arizona’s economy.
With this project, APS and First Solar will continue that tradition.
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 most substantial renewable energy portfolios, and owns and operates
the Palo Verde Generating Station, the country’s top power producer and largest
producer of carbon-free 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
