Virtual Power Plants in California: Can Your Home Battery Earn Money?
Short answer: yes — a home battery can earn money in a virtual power plant (VPP), where a utility, the state, or an aggregator briefly uses your stored energy during grid stress and pays you for it. But for a single home battery the pay is usually modest, and the trade-off is real: the program can discharge the battery you keep for backup. Rates and rules also change most years, so confirm current terms before you count on any number.

VPP programs, enrollment windows, and payments in California change often and can close without notice. Treat every program name, rule, and dollar figure below as a starting point — confirm the current terms with the program administrator or your battery provider before enrolling.
- A virtual power plant (VPP) lets a utility, the state, or an aggregator briefly use your home battery during grid stress — and pays you for it.
- California has several VPP paths: state demand-response (DSGS), utility emergency programs (ELRP), an SGIP upfront-rebate adder, and manufacturer or third-party aggregator programs (Tesla, Sunrun and others).
- Pay is usually modest and comes as per-event, per-kWh, or seasonal-enrollment compensation — amounts and rules change most years, so confirm current terms before you count on any number.
- The main trade-off: the program can discharge your battery, so you may have less stored for your own backup during an outage.
What is a virtual power plant?
A VPP is a network of thousands of home batteries that a utility, a state agency, or a private aggregator can call on all at once during grid stress — hot summer evenings when demand peaks and blackouts loom. Instead of firing up a gas “peaker” plant, the grid draws a little energy from many batteries. You get paid; the grid stays up.
For you as the homeowner, joining a VPP usually means installing an app or letting your installer enroll your battery, then letting the program dispatch it during a handful of pre-announced events each year. In California most programs run their “season” from roughly May through October, with events concentrated in the late-afternoon-to-evening window (commonly 4–9 p.m.) when the grid is tightest. The rest of the year your battery behaves normally.
VPPs are real and growing — California aggregations now link tens of thousands of home batteries. But this is a fast-moving policy area: enrollment windows, eligibility, and payment rates get revised nearly every program year. Treat the numbers below as illustrative of how programs are structured, not as guaranteed current rates.
VPP program types in California — how they pay and the trade-offs
There isn’t one “California VPP.” There are several overlapping types, and some may be compatible — but stacking rules vary and should be confirmed with the program administrator and aggregator before enrolling. Here’s how the main categories generally work. Dollar figures are illustrative of the structure, not a quote — verify the live terms for the current program year.
| Program type | Who runs it | How it generally pays | Trade-offs & things to confirm |
|---|---|---|---|
| State demand-response (DSGS) | California Energy Commission, via aggregators | Seasonal capacity enrollment plus performance during events; the aggregator splits the payment with you | Season is roughly May–Oct; enrollment options and budgets are revised yearly — some options can be suspended or limited |
| Utility emergency program (ELRP) | CPUC, through SCE / PG&E / SDG&E | Typically a per-kWh payment for energy delivered above your normal baseline during rare emergency events | Investor-owned utilities only — LADWP is municipal and not part of ELRP; the residential piece is a pilot whose future is under review |
| Upfront-rebate adder (SGIP VPP bonus) | CPUC / SGIP, claimed by your installer | A larger upfront rebate instead of ongoing payments, if your battery is enrolled through a qualifying VPP aggregator | Flows through the installer, not to you directly; you must use a registered VPP aggregator and accept dispatch commitments |
| Manufacturer VPP (Tesla & others) | Battery maker acts as the aggregator | Per-event or per-kWh compensation; the maker routes you into an underlying state/utility program via its app | You need an eligible battery and app; enrollment windows open and close, and which underlying program applies can change — check status in the app |
| Third-party aggregator (e.g. Sunrun CalReady and others) | Private company dispatches your battery | Per-battery seasonal enrollment, sometimes plus event compensation; the company handles the grid side | The company controls dispatch; good programs keep a backup reserve (e.g. around 20%) for your home — confirm the reserve and the contract length |
Program structures per CEC DSGS, CPUC ELRP, Tesla VPP, and Sunrun CalReady. Payment amounts and eligibility change by program year — confirm before enrolling.
The California programs to know
Most homeowners never sign up for these one by one — your installer or battery maker enrolls you into the ones you qualify for. Still, it helps to know what’s behind the app.
DSGS (Demand Side Grid Support) is a state program run by the California Energy Commission as part of California’s reliability reserve. Aggregators enroll fleets of home batteries and are paid for capacity they can deliver during the May–October season; that payment is then shared with participants. Enrollment options and budgets are set fresh each program year, and some options can be suspended or capped — so what was open last season may not be open this one.
ELRP (Emergency Load Reduction Program) is a CPUC pilot for the investor-owned utilities — SCE, PG&E, and SDG&E. It pays for extra energy you deliver above your normal usage during rare grid emergencies. Because it’s a pilot, its residential component has been re-evaluated over time; treat its future and its rates as subject to change and confirm the current status before relying on it. Note that if you’re on NEM 3.0 with SCE, ELRP is a separate grid-emergency program, not your export credit.
SGIP’s VPP adder is different: rather than ongoing event payments, it can add a bonus to your upfront battery rebate when your system is enrolled through a qualifying aggregator. If a battery rebate matters more to you than trickle earnings, this is the lever — see our SGIP battery incentives guide for how the rebate itself works and its waitlist reality.
Manufacturer and third-party VPPs — Tesla’s Powerwall program, Sunrun’s CalReady, and others — are the front doors most homeowners actually use. They enroll your battery and dispatch it into one of the underlying programs above. Which underlying program a maker uses, and whether new enrollment is open, has shifted from season to season, so check inside your app rather than assuming.
How VPPs generally pay you
Compensation comes in a few shapes. Most programs use one or a blend of these — and the exact figures are the part most likely to change.
Per event
A flat amount each time the program dispatches your battery during a grid event. There’s usually a minimum number of events per season, but no guarantee of more.
Per kWh dispatched
You’re paid for each kilowatt-hour your battery sends above your normal baseline during an event. Bigger, fuller batteries can deliver — and earn — more.
Seasonal enrollment
A set amount just for enrolling a battery and making it available across the May–October season, sometimes topped up by event performance.
Upfront rebate adder
Instead of ongoing pay, a larger one-time rebate on the battery itself (the SGIP VPP bonus), claimed through your installer.
Stacking
Some programs can be combined so a battery earns from more than one at once. What stacks — and what doesn’t — changes yearly, so verify.
Reality check
For a typical single home battery, VPP earnings vary widely — from no guaranteed payment to event-based or seasonal payments, depending on the program, battery, dispatch performance and enrollment year — a possible bonus, not a payback engine. Don’t buy a battery for VPP income alone.
The program can drain the battery you bought for backup
When a VPP dispatches your battery into the grid, that’s energy you no longer have stored for your own home. If a PSPS shutoff or outage hits right after an event, you could have less reserve than you expected. Well-designed programs keep a minimum backup reserve (Sunrun’s CalReady, for example, describes keeping a backup reserve for enrolled homes — confirm the current figure and terms) — but the exact reserve, and whether you can opt out of a given event, varies. If backup is your top reason for owning a battery, confirm the reserve rules before enrolling.
Should you enroll? How to decide
VPP participation is generally low-effort once set up, and modest income for letting your idle battery help the grid is a fair deal for many homeowners. A few questions sort it out.
Why did you buy the battery? If it’s primarily for outage backup, prioritize a program with a solid guaranteed reserve and easy event opt-out. If it’s mainly for bill management under NEM 3.0, check that VPP dispatch times don’t collide with the evening hours when your own self-consumption is most valuable.
Is your battery eligible and big enough? Eligibility depends on the battery brand and how it’s wired. Our comparison of Powerwall vs Enphase vs FranklinWH covers which ecosystems plug into which programs, and our battery sizing guide helps you judge whether you have enough capacity to both back up your home and contribute.
LADWP customers, note: ELRP is for the investor-owned utilities, not municipal LADWP. If you’re in the LADWP territory much of Los Angeles sits in, your VPP options generally run through the statewide DSGS program (via a participating aggregator or battery provider) and manufacturer/aggregator programs rather than utility ELRP — another reason to confirm what’s actually available at your address.
Confirm the current terms — they change most years
Because programs are revised nearly every season, don’t rely on a payout figure you read online (including in this article). Ask three things in writing: (1) which program you’re being enrolled in and how it pays this program year; (2) the guaranteed backup reserve and whether you can skip an event; and (3) the contract length and how to leave. A good installer will answer all three plainly.

Frequently asked
Can my home battery really earn money in California?
Yes — through a virtual power plant (VPP), a utility, the state, or an aggregator can use your battery during grid stress and pay you for it. But for a typical single home battery the income varies widely — from no guaranteed payment to event-based or seasonal payments, depending on the program, your battery, dispatch performance and enrollment year — and rates change nearly every program year. Review the current program terms rather than assuming a fixed annual amount. Treat it as a bonus, not a reason on its own to buy a battery, and confirm current terms before you count on any figure.
What VPP programs exist in California in 2026?
The main types are the state’s DSGS demand-response program (CEC), the utilities’ ELRP emergency program (CPUC, for SCE/PG&E/SDG&E), an SGIP upfront-rebate VPP bonus, and manufacturer or third-party aggregator programs such as Tesla’s Powerwall program and Sunrun’s CalReady. Some incentives or programs may be compatible, but stacking rules vary — confirm with the program administrator and aggregator before enrolling. Enrollment rules and budgets are revised each program year, so verify what’s currently open.
How do VPPs actually pay — per event or per kWh?
It depends on the program. Common structures are per-event payments, per-kWh for energy delivered above your normal baseline during an event, seasonal enrollment payments for making the battery available, or an upfront rebate adder (SGIP) instead of ongoing pay. The exact dollar amounts are the part most likely to change, so confirm the current terms.
Will a VPP drain the battery I keep for backup?
It can — during an event the program discharges some of your stored energy to the grid, leaving less for your own use. Well-designed programs keep a minimum backup reserve (for example, Sunrun’s CalReady describes retaining a backup reserve for enrolled homes — confirm the current figure), and many let you opt out of a given event. If backup is your main reason for owning the battery, confirm the reserve and opt-out rules before enrolling.
Can LADWP customers join a VPP?
The utility ELRP program is for the investor-owned utilities (SCE, PG&E, SDG&E), not municipal LADWP. LADWP-area homeowners may be able to participate in DSGS-supported services through a participating aggregator or battery provider, subject to current program eligibility and enrollment availability. Because much of Los Angeles is LADWP territory, it’s worth confirming which specific programs are available at your address.
Does joining a VPP affect my SGIP rebate or NEM 3.0 credits?
They’re separate mechanisms. SGIP is an upfront battery rebate that can include a VPP bonus; NEM 3.0 governs the credit for solar you export daily; a VPP pays for grid-emergency dispatch. Enrolling through a qualifying aggregator may unlock the SGIP VPP bonus, but you should confirm how any program interacts with your export plan before signing.
