Nine storage systems provide about 200 megawatts (MW) of power, enough to serve 32,000 Arizona homes for three to four hours. Additional energy storage systems are planned in the coming years.
Reliable, affordable clean
Technological advances make energy storage a viable option to maximize the use of renewable energy and enhance reliability at times when customers need it most, especially during the hot summer months when energy use soars.
Partnering with customers
In the APS Residential Battery Pilot, we are working with customers to learn how customer-owned battery storage technology can be integrated with the grid to deliver customer value and strengthen system reliability. Participating customers receive incentives for installing battery systems in their homes and sharing information about how those systems perform.
Focus on safety
Our energy storage facilities are built and activated with safety top of mind – the safety of the public, first responders and employees. We work closely and collaboratively with first responders, utilities, industry partners and developers to share safety information, best practices and ongoing education and training.
We committed to delivering 100% clean and carbon-free energy by 2050 while maintaining reliability and affordability for customers. Our pathway to a clean energy future includes increasing renewable energy resources, investing in energy storage, working with customers to manage their energy use, and generating clean, carbon-free energy from Palo Verde Generating Station, the nation’s largest single source of electricity.
