Program summary
Put Stored Energy to Work During Arizona's Highest-Demand Hours
The APS Storage Rewards Pilot pays eligible residential battery owners for helping reduce grid demand during summer events.
How the Program Works
APS calculates the battery's average kW contribution across the May-through-October season and applies a bill credit at the published rate after the season.
What to Know
- APS may call up to 60 events during the summer season.
- Events generally occur between 4 p.m. and 10 p.m. and last one to four hours.
- The system needs permission to operate, reliable internet, and equipment accepted by APS.
Review the official program website for the latest terms and eligible-equipment requirements.
