REMOTELY FROM TUCSON - The Arizona Corporation Commission last week approved a new pilot program for Arizona Public Service Company that will provide up to $2,500 for the purchase and installation of at-home energy storage devices that can capture electricity from the grid or rooftop solar and dispatch it for later use.


“Residential energy storage is the future and the solution to providing reliable, affordable energy to families throughout the evening hours when solar is not available. Technology is still developing in energy storage and increased adoption will drive the price lower for families over time,” said Márquez Peterson.


“In order to transition to a cleaner energy future, we need solutions that can not only heat and cool our homes during the hottest summers and coldest winters, but also solutions that can do so late into the evening hours, long after the sun has set,” said Márquez Peterson.


Commissioner Lea Márquez Peterson proposed and passed a pilot program for residential APS customers and increased the incentive per household from $300 per kilowatt to $500 per kilowatt, so Arizonans would be incentivized to purchase and install energy storage. 


“By approving APS’s residential energy storage pilot program, we are providing customers an affordable energy opportunity as many work and learn from home. This pilot program will allow the utility company to study the grid impact and incorporate best practices for these systems in our unique Arizona climate.”
