Arizona Public Service Co. has introduced a Residential Battery Pilot Program, starting October 4, 2021.
The pilot will be available to APS residential customers who install residential battery systems, enroll in a TOU (Time of Use) or TOU-plus-demand service plan and commit to discharging their batteries during on-peak periods. (Note: Rate requirements are waived for customers on grandfathered solar rates.) The pilot will help APS learn about battery performance in a variety of conditions and how batteries may create value for customers through improved management of energy demand at their residence and help reduce stress on the electric grid.
