Arizona Public Service Storage Rewards Pilot Program

Support a reliable, affordable and clean energy future… and get paid to do it.

Help reduce stress on the power grid and earn rewards in the APS Storage Rewards pilot - it's a win-win!

Arizona Public Service customers can get paid for using their battery during periods of peak electricity demand—like hot summer days. Participate through your Fortress battery to receive an annual $110/kW capacity payment. For example, customers with eForce 28.8 batteries could earn an average of $800 for the summer season, based on their expected performance.

The APS Storage Rewards pilot is a resource to help support a reliable, affordable and clean energy future. During periods of high demand an event may be called, and your battery manufacturer will signal your battery system to discharge stored energy back to the power grid.

How to Participate

Confirm Your Eligibility

Eligibility Requirements:

  • Be an Arizona Public Service (APS) customer
  • Your Fortress Power system must have a Guardian Monitor, Envy Inverter and any Fortress Power battery
  • Must have a reliable internet connection
Find an Installer

Select an installer through APS’s list of Qualified Technology Installers.

Install Your System

All Fortress Power Residential systems are eligible for the program, and must be paired with the Guardian Monitor to remit information back to your power supplier.

Enroll in the Pilot

After the installation is complete, enroll in the program via our simple EnergyBroker application.

Get Paid!

Once your system is operational and all eligibility requirements have been verified, APS will issue a bill credit based on the average power discharged during the events.

Program Benefits

Earn Performance Incentives

Performance incentives are paid at the end of each summer via a bill credit based on the average kilowatt (kW) used per event, averaged over the season. The expected performance incentive earned is calculated assuming 80% of the battery energy capacity is used over three hours for each event.

Take Advantage of the Federal Tax Investment Credit (ITC)

You may also qualify for a Federal Tax Investment Credit (ITC). Consult with a tax advisor on eligibility requirements.

Contribute to a Cleaner Future

Unlike generators that run on fossil fuels, batteries are a cleaner, quieter option for powering your home during an outage. APS calls on the batteries instead of the most expensive, dirty sources of power. Your contribution directly adds renewable energy to the grid when it’s needed most, making a positive impact on our environment and community.

How the Pilot Works Once Your System is Installed

System Monitoring

The battery storage system needs to be installed in a location with an internet service so APS can monitor your system. The Guardian Gateway is required to program communications. You can see the same information using our mobile app.

Battery Dispatch & Parameters

After your battery is installed, APS will dispatch energy from your battery to help reduce peak electricity demand.

– Up to 60 discharge events per year

– Can occur any day

– Between 4pm-10pm (coincides with APS Peak Time of Use rates on weekdays)

– Events are expected to last 1-4 hours

– Summer season takes place from May 1 through October 31.

Incentives

Participating customers receive performance-based incentives that are paid via a bill credit at the end of each summer based on average energy contributions to the grid.

Potential Customer Incentives
