California DSGS (Demand Side Grid Support) VPP Option 3 Battery Payout Guide
Funded directly by the California Energy Commission (CEC), the Demand Side Grid Support (DSGS) Option 3 VPP pays PG&E, SCE, and SDG&E battery owners monthly summer capacity incentives ($280–$420/kW-year) on top of their daily NEM 2.0/3.0 bill savings.

| Home Battery Configuration | Estimated Annual VPP Payout | 5-Year Cumulative Value |
|---|---|---|
| Single Battery (13.5 kWh / 5.0 kW Average Event Export) | $1,150 – $1,550 / yr | $5,750 – $7,750 |
| Dual Battery Bank (27–28.6 kWh / 10.0 kW Average Event Export) | $2,300 – $3,100 / yr | $11,500 – $15,500 |
| Triple Battery Bank (40.5 kWh / 15.0 kW Average Event Export) | $3,450 – $4,650 / yr | $17,250 – $23,250 |
2. VPP Dispatch Rules, Backup Reserves & Aggregator Fine Print
- 1DSGS Option 3 operates from May through October during 4:00 PM – 9:00 PM hours when CAISO day-ahead wholesale prices or grid stress cross trigger thresholds.
- 2Your aggregator (Tesla Electric VPP, Enphase, FranklinWH, or SolarEdge) automatically pre-charges your battery from rooftop solar before 4:00 PM and dispatches stored kWh during the 2-hour evening peak window.
- 3Aggregator Fee Split Warning: Check your VPP aggregator’s revenue split—most aggregators pass through 70% to 85% of the gross CEC DSGS payout directly to the homeowner via check or ACH while retaining 15%–30% for telemetry aggregation.
- 4Crucial Rule for Leased Batteries: If you signed a Sunrun or Sunnova PPA, read Section 8—many lessors keep 100% of DSGS VPP payments for themselves! You only keep 100% of VPP checks when you OWN your battery hardware.

CEC Demand Side Grid Support (DSGS) — Option 3 Behind-the-Meter Battery VPP FAQ
Can I enroll in both California DSGS and PG&E/SCE ELRP at the same time?
No. CEC DSGS rules prohibit dual-participation in conflicting utility emergency demand response programs (like ELRP). However, DSGS Option 3 typically pays 2x to 3x more per summer than standard ELRP because it compensates monthly capacity across the entire May–October season.
Does participating in DSGS void my LFP battery warranty?
No! LFP (Lithium Iron Phosphate) batteries are rated for 6,000 to 8,000 cycles, and 25 summer VPP events add less than 20 full-equivalent cycles per year (<0.3% of total battery lifespan).
