FAQs

Yes. CalReady is a Sunrun Distributed Power Plant similar to a virtual power plant (VPP). Sunrun manages the coordination between your system and the grid. Sunrun customers who participate receive the benefits directly from Sunrun. CalReady is simply a perk of being a Sunrun customer.


CalReady is available to qualifying Sunrun solar & storage customers in California. Eligible customers will be contacted by Sunrun via email, notifying them that they qualify and are enrolled before the start of each Sunrun CalReady season.

Following the conclusion of the Sunrun CalReady summer season of  10/31/26 participants will receive more information regarding their final reward amount directly from Sunrun. Sunrun will notify Participants when the Sunrun Incentive is available in Spring 2027.

Depending on certain system characteristics, your battery will either be programmed to operate in “Self-Powered” or “Time-Based Control” mode.

Your battery’s programming may change throughout the program season to balance high export credit values and Sunrun CalReady participation.

Sunrun batteries are equipped with smart features that prioritize your energy needs while maximizing earnings in Sunrun CalReady. Sunrun will seamlessly control and monitor your system. During a grid event, your battery will send energy to your home and then the grid (if extra is available), until reaching your backup reserve. Otherwise, your system will operate under default optimized settings.

We may initiate behaviors, including telling your system to:

  • Prioritize using your solar production to charge the battery

  • Keep energy stored in your battery, or

  • Discharge the stored solar energy to the grid

In certain months, batteries may dispatch daily to take advantage of the utility’s high-value solar export credits. How your battery is programmed will determine its discharge behavior.

  • In August

    • Time-Based Control mode: Daily export in the afternoon

    • Self-Powered mode: Daily export from 9:00 PM - 11:00 PM PST

  • In September:

    • Time-Based Control mode: Daily export in the afternoon

    • Self-Powered mode: No daily export

Regardless of your battery mode, if a grid event is called for the Sunrun CalReady program between the hours of 4:00 PM to 9:00 PM, your battery will prioritize dispatching for this event.

 Your participation for the full Sunrun CalReady season means you will receive rewards from Sunrun in addition to any high-value solar export credits earned!


During a power outage your battery system will not send any power to the grid. Storm Mode (an automatic Sunrun setting for any non-Tesla Powerwall systems) or Storm Watch (if enabled in the Tesla app for Powerwalls) will keep participants' homes prepared for critical storms and severe weather.

Participating systems maintain a minimum 20% backup reserve in case of power outages. Storm Mode and Storm Watch will add another layer of protection for critical storms and severe weather. (Shift™ batteries do not provide backup power during an outage).

As energy demand continues to increase and outpaces the supply, Sunrun CalReady provides a fast and meaningful way to provide large scale capacity of energy to the California grid. Sunrun CalReady is a network of tens of thousands of Sunrun home battery systems across California, coordinated to offset grid strain and reduce power outages. When energy demand is high, SunRun CalReady distributes energy back to the grid, bypassing the need for peaker stations. In return, Sunrun passes on rewards to Sunrun CalReady participants as a way of sharing benefits across the system.
