APS Announces Major New Clean Energy Initiatives
April 2019

Every day, our nation’s electric companies work to provide their customers with safe, reliable, affordable, and clean energy. Arizona Public Service (APS) customers soon will have the ability to power their homes and businesses with solar after sunset thanks to three major clean-energy initiatives.​

APS announced it will add new battery storage and will build new solar plants with storage to deliver cleaner energy to customers at times of peak energy usage.

APS already provides its customers with an energy mix that is 50 percent clean – it is only getting cleaner. The recently announced initiatives will add 850 megawatts (MW) of battery storage and at least 100 MW of new solar generation by 2025. This will bring an additional 950 MW of new clean energy technology to the state and to customers, allowing them to use solar energy even after the sun goes down.

“Arizona is already a national leader in solar energy. The challenge is, no one has figured out how to stop the sun from setting at night,” said APS Chairman and CEO Don Brandt. “As storage technology improves and declines in cost, we will increasingly be able to store the power of the sun cost-effectively to deliver when our customers need it.” 

Shortly after the announcement, U.S. Secretary of Energy Rick Perry visited the Festival Ranch facility in Arizona for a tour of the power plant and one of the new batteries. Secretary Perry applauded APS and called its new investments “a great example of an all-of-the-above energy policy.” The battery, which is about the size of a small house, helps to keep the energy grid safe and reliable for customers who typically power their homes with solar.

APS also owns and operates many universal solar plants throughout the state of Arizona. These plants will be upgraded with 200 MW of battery storage systems, and six new battery systems will be installed at the company’s solar plants in Maricopa County and Yuma by 2020.

Additionally, APS plans to build 500 MW of solar storage and stand-alone battery storage by 2025. The company has partnered with Tempe-based First Solar to build a first-of-its-kind solar-plus-storage project that will be one of the largest in the country when completed in 2021. 

This is just another example of how electric companies are staying at the forefront of new technologies and are delivering clean and affordable energy to all customers.
