Technology and Innovation
APS Solar Communities
We established APS Solar Communities in concert with regulators and community stakeholders during the 2017 rate case settlement. With up to $45M to spend over three years, APS Solar Communities expands access to rooftop solar systems for limited-income customers and the agencies that serve them. Systems are maintained and operated by APS, and connect directly to our distribution system. Customers receive a monthly bill credit for participating.
Our customer programs
Cool Rewards is not your average smart thermostat demand-response program—think pre-cooling a home during midday off-peak hours to shift load away from on-peak, high-use periods. Not only might this provide time-of-use customers with greater savings opportunities, but with nearly 13,000 registered thermostats as of summer 2019, it can help us integrate more solar energy onto the grid.
Storage Rewards expands our energy storage portfolio to include at least 40 residential and 1 to 2 commercial batteries in addition to our grid-scale battery storage systems. The Storage Reward batteries are installed behind the meter, where they can offset customers' energy usage. To maximize integration of solar at midday, residential participants need to live on select feeders and be on one of our Saver Choice service plans. APS will own and maintain the residential batteries for up to 10 years.
Reserve Rewards provides rebates for 200 residential hybrid heat pump water heaters in areas experiencing high solar penetration. This provides customers with an energy-efficient technology aligned to our Saver Choice service plans and helps APS soak up excess solar energy at midday. Customers own their water heaters and agree to let APS manage the devices.
APS Solar Partner
APS Solar Partner was the nation's first utility-owned deployment of residential rooftop solar systems with wireless management of advanced inverters. (This program matured into APS Solar Communities.) It includes battery storage units on distribution feeders in Buckeye and Surprise, where solar penetration is high.
