Receive incentives by unlocking the full potential of your battery system

DSGS is a new program offered by California Energy Commission, also known as the CEC, that pays participants a cash incentive for load reduced by using (discharging) electricity stored in their own battery during peak demand periods or program events. DSGS events may last between two and four hours and will be scheduled between 4 p.m. and 9 p.m. on days they occur. Up to 35 events will be scheduled during each DSGS season, which lasts May 1 – October 31.

If you choose to participate, Enphase will discharge your battery system during each DSGS event at the kW rate you select as part of your program enrollment, down to the Backup Reserve you select for your battery. The CEC will evaluate the load reduction your battery discharge creates and pay Enphase for the aggregate reduction in load across all participating batteries. Enphase will then remit this payment to you, based on your system’s contribution, minus an anticipated 15% service fee to help cover our costs for operating the program.

All SCE and SDG&E customers with an Enphase battery system are eligible to participate in DSGS.

You can apply to participate in DSGS by opening your Enphase App, tapping Menu > Services > Grid Services, and selecting either Southern California Edison or San Diego Gas & Electric. After you complete the enrollment forms provided, Enphase will send the information you enter to the CEC for review. If they accept your application, Enphase will finalize your enrollment.

Yes, customer battery systems—including IQ Battery 3T, 10T, and 5P—are all eligible to participate in DSGS.

This will largely depend on your interconnection tariff with SCE or SDG&E.

For customers with systems interconnected under the SCE or SDG&E Net Energy Metering 1.0 or 2.0 tariff, also known as NEM 1.0 and NEM 2.0, the battery system is typically only permitted to discharge to reduce onsite load; it cannot export to the grid. This means customers will only be compensated based on the amount of kW that coincides with their onsite load during the time of a DSGS program event. Practically speaking, this means NEM 1.0 and NEM 2.0 customers can expect to earn approximately $150-200/year as part of DSGS.

For customers with systems interconnected under the SCE or SDG&E Net Energy Metering 3.0 tariff, the battery system may be permitted to discharge in excess of load, exporting to the grid.* This means that customers may be compensated up to the maximum kW discharge rating of their battery system, depending on the amount of kW they choose to enroll in the program. Practically speaking, this means NEM 3.0 customers can expect to earn approximately $150-450/year as part of DSGS.

For program year 2024, all Enphase customers will be enrolled in 2-hour program events. Starting in program year 2025, customers may have the option to enroll in 2-hour, 3-hour, or 4-hour events. The availability of 3- or 4-hour events will depend on the CEC’s evaluation of 2024 battery system performance and approved incentive payments.

*Customers can contact their installer for additional information on the terms of their utility interconnection agreement (i.e., whether or not their system is permitted to export to the grid).

During the enrollment process, you will need to select the kilowatt (kW) rate at which you would like your battery system to discharge during DSGS events. The amount of energy (kilowatt-hours or kWh) you deliver during an event will be the kW rate multiplied by the duration of the event.

For example, if you have two IQ Battery 5Ps installed with 10 kWh of capacity and you select a 3 kW discharge rate, are interconnected under the NEM 3.0 tariff, and your DSGS event lasts two hours: You will discharge a possible total of 6 kWh of energy—or less, if you set a Backup Reserve higher than 4 kWh.

You can also choose to opt out of any event, though this may reduce the total participation incentive you receive.

Currently, the CEC has allocated approximately $300 million for the DSGS program budget. The program is expected to continue until these funds are either exhausted or reauthorized. We estimate that the current funding level will allow the program to operate through 2027, though this timetable may shift depending on how quickly program funds are exhausted.

You are free to leave the program at any time by providing written notice to gridservicessupport@enphaseenergy.com. Leaving the program before an event year is complete will likely reduce the program participation incentive you receive.

IQ Batteries will remain active with backup mode enabled if there’s a grid outage during an DSGS event. You will only be asked to discharge your battery during DSGS events, and you can choose to opt out of any event.

Participants may opt out of a DSGS event by selecting the Opt-out feature in the Enphase App prior to the event. Opting out of events will likely lower your credited load reduction performance and thus reduce the total compensation you receive for participating in DSGS.

No, you may only participate in one battery program at a time. If you are enrolled in another battery program and would like to participate in DSGS, you will need to unenroll from that program before joining DSGS.
