Service Plans Unlock New Home Technologies

October 01, 2018

Innovations can reduce customers’ peak usage and relieve strain on energy grid

Today, 20 percent of APS residential customers are enrolled in service plans that include a peak hour usage charge.

These service plans, Saver Choice Plus and Saver Choice Max, offer customers more ways to save. Customers who can reduce their energy use during on-peak hours from 3-8 p.m. weekdays, typically the heaviest time for energy demand on the grid, can increase their savings. This makes technologies that lower customers’ peak usage even more attractive.

Tech companies are taking notice, looking at Arizona as a prime market to introduce more peak-reducing technologies in conjunction with the service plans. Here are some of the technologies now available for customers who seek more choices to manage their energy use and save money:

  1. Programmable or smart thermostats: Options range from basic manually programmed models to WiFi-enabled units controlled via a mobile app that adapt to a household’s lifestyle.
    Learn more about APS incentive programs for customers who install new smart thermostats in their homes, including the Cool Rewards program.
  2. Demand limiter or load controller: Devices installed on appliances such as an electric hot water heater, dryer or pool pump to control their use during on-peak hours.
    Learn more about APS customer programs for grid-connected hot water heaters and hot water heater timers.
  3. Home energy management system: This allows you to monitor the energy use of various appliances in your home and control when and how often they run.
  4. High-efficiency HVAC systems, pool pumps: These advanced units reduce energy use and offer better overall performance compared to older models.
  5. West-facing solar panels: Solar panels installed on west- or southwest-facing rooftops generate more energy during peak use times to benefit a household and the grid.
  6. Advanced solar inverter: Besides converting solar energy into usable electricity, advanced inverters enable a utility to regulate the amount of energy flowing from solar panels to the grid, ensuring a reliable energy supply.
    APS was the first U.S. energy company to deploy and remotely control advanced inverters as part of its award-winning Solar Partner program. A research partnership with the Electric Power Research Institute yielded valuable insights about the inverters’ capabilities.
  7. Battery energy storage: Battery storage works with rooftop solar systems to more fully capture the benefits of solar energy. Batteries store excess solar energy generated at midday and then supply power during on-peak hours, when demand is higher and electricity costs more, to help customers manage their peak usage.
    APS is studying battery storage performance for residential customers as part of the Solar Innovation Study and Storage Rewards program.

Service plans such as Saver Choice Plus and Saver Choice Max can open the door for these technologies and more. Together, they can help customers reduce peak usage, save money and use the grid more efficiently, benefiting all customers in the long run.


Customers have an increasing number of energy-management technologies available to help them conserve energy and reduce their bills.
