Here's how they work and what you can earn."

Virtual Power Plants Go Mainstream

Virtual Power Plants (VPPs) — networks of distributed batteries that act collectively as a single power resource — crossed a milestone in 2025. Multiple major utilities now operate VPPs with tens of thousands of enrolled homes, and the revenue opportunity for battery owners is becoming significant.

What Is a VPP?

A VPP aggregates thousands of home batteries (and sometimes smart thermostats, EVs, and water heaters) to function like a traditional power plant:

• During grid stress events (extreme heat, high demand), the VPP operator sends a signal
• Enrolled batteries simultaneously discharge to the grid or reduce home consumption
• The aggregated response from thousands of homes provides megawatts of capacity
• This displaces the need for expensive gas "peaker" plants

Active VPP Programs (2025–2026)

| Program | Utility/Company | Enrolled Homes | Annual Payment | |---------|----------------|:-:|:-:| | Tesla Virtual Power Plant | Multiple utilities (PG&E, Green Mountain, etc.) | 100,000+ Powerwalls | $350–$750 | | OhmConnect (via batteries) | PG&E/SCE territory | 50,000+ homes | $200–$500 | | Green Mountain Power | Vermont utility | 7,000+ | $850–$1,100/year (includes battery lease) | | ConnectedSolutions | National Grid, Eversource, Cape Light | 15,000+ | $225–$500/season | | Portland General Electric | PGE (Oregon) | 5,000+ | $300–$600 | | South Australia VPP | SA Power Networks | 50,000+ | AU$400–$800 | | Sunrun Grid Services | Multiple utility partnerships | 30,000+ Sunrun batteries | $300–$600 |

Revenue Models

How You Get Paid

Capacity payments: You receive a fixed annual or seasonal payment for making your battery available. The VPP operator doesn't always dispatch — they pay for the option to use your battery during events.

Performance payments: You're paid per event based on the energy (kWh) your battery dispatches. More events = more pay.

Bill credits: Some programs provide credits on your electricity bill rather than cash payments.

Typical Earnings

| Battery Size | Annual VPP Revenue | |:-:|:-:| | 5 kWh (Enphase) | $100–$250 | | 10 kWh | $200–$500 | | 13.5 kWh (Powerwall) | $350–$750 | | 20+ kWh | $500–$1,200 |

These earnings are in addition to the bill savings and backup value your battery already provides.

How It Affects Your Battery

What You Give Up

• During VPP events (typically 10–50 events per year, 1–4 hours each), your battery discharges to support the grid
• Some programs require keeping a minimum state of charge (e.g., 20–30%) to ensure you still have backup
• You generally have the option to opt out of individual events (with potential reduction in annual payments)

What You Keep

• Backup protection during outages (VPP events only occur when the grid is up)
• Normal TOU optimization when VPP is not dispatching
• Full control of your battery the vast majority of the time

Battery Wear

Additional cycling from VPP participation adds some degradation:

• Typical VPP participation adds 20–50 extra cycles per year
• On a battery rated for 5,000+ cycles, this is ~1% additional wear per year
• The revenue from VPP participation typically more than compensates for any marginal degradation

FERC Order 2222

The Federal Energy Regulatory Commission's Order 2222 (issued 2020, implementation ongoing) requires wholesale electricity markets to allow aggregations of distributed energy resources (including VPPs) to participate alongside traditional power plants. This is a landmark policy that:

• Opens wholesale energy, capacity, and ancillary service markets to VPPs
• Could increase VPP revenue as they compete with gas peakers in capacity auctions
• Is being implemented by regional grid operators (PJM, NYISO, CAISO, etc.) on varying timelines
• Expected to significantly increase the value proposition for home batteries

Getting Started

To participate in a VPP:

1. Own a compatible battery: Tesla Powerwall, Enphase, Franklin WH, and others are supported by various programs
2. Check your utility: Visit your utility's website or contact them about demand response / VPP programs
3. Enroll: Registration is typically through the battery manufacturer's app or the utility's portal
4. Set preferences: Most programs let you set minimum backup reserve and opt-out preferences
5. Earn passively: The VPP operator manages dispatch; you receive payments automatically

For homeowners considering a battery purchase, the growing availability of VPP programs adds $200–$750/year in revenue that should be factored into the payback analysis.
