Power Partner℠ Battery

Become a Power Partner

Power Partners help the community manage energy use on days when the demand is highest. During these times, Austin Energy briefly uses a small amount of energy from the battery until the system reaches your backup reserve level.

As a Power Partner, you can:

• Earn rewards for each battery you enroll
• Help lower the cost of electricity in our community
• Enhance power grid reliability during periods of peak energy demand
• Reduce your carbon footprint

Two incentive offerings:

• If you had a battery recently installed: Austin Energy offers a $500 rebate for each battery system that gets Permission to Operate (PTO) after passing Austin Energy’s final inspection on or after 2/18/25. Click the Incentive tab for details.
• Performance payment: Austin Energy will pay you each year based on the maximum device size, backup reserve level, and average event hours. Click on the Incentive tab for details.
• Note: Third party-owned (TPO) batteries are not eligible.

Power Partner Events

Power Partner Battery events:

• Can occur on any day of the year and at any time during the day, including weekdays and holidays.
• Typically last 2-3 hours.
• Are limited to 40 per year, excluding grid emergencies.
• Can be overridden by you at any time before and during an event by using your battery manufacturer's app. Please note: Enphase systems only allow opting out up to five minutes before the event starts. There is no penalty for opting out of individual events, but doing so will affect your annual performance payment.
• Will not reduce your systems’ reserve below your back-up reserve margin. Battery systems will typically regain full charge within less than 24 hours of being dispatched.
• Will allow your battery to export excess electricity to the grid. A residential battery powers your home first, then sends extra power to the grid.
• Austin Energy will typically not call events if a severe storm is forecast to ensure customers‘ battery storage systems can be utilized for backup power if needed.

Austin Energy itself does not send Power Partner event notifications, which are set by the battery manufacturer. Event notifications are displayed in your battery app both before and during events.

Power Partner Battery offers two incentives:

• Recent installation: Austin Energy offers a $500 rebate for each battery system that gets Permission to Operate (PTO) after passing Austin Energy’s final inspection on or after 2/18/25. Austin Energy will verify the PTO date with the Austin Services Department upon receiving your enrollment.

  • Payments are issued as checks via mail and will be sent to your home address from our third-party vendor. (Make sure to give your correct home address when enrolling.) Please allow 1-2 billing cycles (4-6 weeks) to receive payment.
  • If you have yet to purchase a battery, Austin Energy’s installation and inspection requirements are similar to those for residential solar systems. View guidance on the permitting process. (Note: A solar system is not required for either installing a battery system or enrolling in Power Partner Battery.) Your battery’s manufacturer can refer you to a certified installation company.

• Performance payment: Austin Energy will pay you $75/kW each year based on the maximum device size, backup reserve level, and average event hours. Click on the Incentive tab for details. For example, a Tesla Powerwall has 13.5 kWh. A 20% reserve provides Austin Energy with 10.8kWh of usable energy. With an average of 2.5 hours per event: (10.8 kWh)/2.5 = 4.3 kW performed average across events; 4.3 kW * $75 = ~$324 per battery per year. (Disclaimer: Costs for recharging your battery may vary based on billing rates, metering configurations, and whether you have solar generation (Value of Solar credit applies). In all cases, these costs will be less than the incentive payment, ensuring a net benefit.

  • Payments are issued annually as checks in the mail after the end of each calendar year in which the system has been enrolled. Checks will be sent to your home address from our third-party vendor. (Make sure to give your correct home address when enrolling.) Please allow 2-3 billing cycles (8-10 weeks) for processing after the conclusion of each year.
