How to Use This Calculator

Select your VPP program and battery

Choose your VPP program from the dropdown. Different programs pay in different ways: Tesla VPP pays approximately $2/kWh dispatched per event; ConnectedSolutions pays up to $225 per kW of enrolled capacity for the summer season; OhmConnect pays per "OhmHour" event; Green Mountain Power pays a flat annual rate. Enter your battery capacity — VPP dispatch typically uses 80% of your battery per event.

Enter events per year and solar details

Events per year is typically listed in your VPP enrollment agreement. Tesla VPP: 10–30 per year. ConnectedSolutions: 10–15 summer events. OhmConnect: 30–50 OhmHours per year. Enter your solar system size and self-consumption rate to see the full comparison between no-battery, battery-only, and battery-plus-VPP scenarios.

Read the results

The calculator shows annual VPP earnings, earnings per event, revenue per kWh of battery capacity, a three-way comparison of annual value, battery payback with and without VPP, months of payback acceleration, and a 10-year cumulative VPP income projection. An eligibility note reminds you of program requirements.

The Formula

kWh dispatched per event = Battery Capacity × 80% dispatch rate For per-event programs: Earnings per event = kWh dispatched × Rate per kWh Annual VPP earnings = Earnings per event × Events per year For per-kW programs (ConnectedSolutions): Annual earnings = Battery kW × Program rate per kW Battery kW = Battery kWh ÷ 2 (2-hour discharge rate) Revenue per kWh capacity = Annual VPP earnings ÷ Battery kWh Battery payback = Battery Cost ($800/kWh) ÷ Annual value (solar + VPP) Months acceleration = (Payback without VPP − Payback with VPP) × 12 10-year cumulative = Annual VPP earnings × 10

The 80% dispatch rate reflects typical VPP program operation — programs rarely discharge batteries to 100% to preserve battery health and ensure availability for grid emergencies. The $800/kWh installed battery cost is a 2026 US average for LFP systems including inverter and installation.

Example

James — Tesla VPP participant in California with 13.5 kWh Powerwall

James has a 13.5 kWh Powerwall 2 and an 8kW solar system in Sacramento. He's enrolled in the Tesla Virtual Power Plant program and receives approximately 20 dispatch events per year. He self-consumes 50% of his solar generation.

Revenue per kWh battery$32/kWh/yr

10-year cumulative VPP income$4,320

Battery payback with VPP~8.4 years

Payback acceleration~16 months faster

$432/year from VPP participation requires minimal effort from James — the Powerwall discharges automatically during events. Combined with self-consumption savings, his 13.5 kWh battery pays back in ~8 years vs ~9.5 years without VPP. The VPP also provides grid resilience benefits to his community during California heat events and peak demand periods.

FAQ

What is a Virtual Power Plant (VPP) and how does it work? ▼

A Virtual Power Plant aggregates hundreds or thousands of home batteries into a coordinated fleet that acts like a single large power plant. During peak demand events — usually hot afternoons when the grid is stressed — the VPP operator sends a dispatch signal to all enrolled batteries simultaneously, causing them to discharge and supply power to the local grid. This prevents blackouts and replaces the need for expensive peaker plants. As the battery owner, you receive payment for making your battery available and for the energy dispatched. The system is fully automated — your battery discharges during events without any action required from you.

How much can I realistically earn from Tesla VPP participation? ▼

Tesla VPP participants in California have reported earnings of $100–$600/year depending on event frequency and dispatch level. The program pays approximately $2/kWh dispatched, and a 13.5 kWh Powerwall might dispatch 8–12 kWh per event. With 15–30 events per year, annual earnings range from $240–$720. Events are concentrated in summer months (July–September) when California demand peaks. Texas and Vermont programs may have different event frequencies. Tesla has not published guaranteed event counts — results vary by year and region.

Does VPP participation degrade my battery faster? ▼

VPP programs are designed to minimize battery degradation. Tesla VPP typically dispatches to a minimum state-of-charge (usually 20–30%) rather than full discharge, limiting depth of discharge. Programs like ConnectedSolutions that pay per kW rather than per kWh may use shallower discharges. Additional VPP cycling adds roughly 20–50 full equivalent cycles per year, which for an LFP battery rated at 4,000 cycles represents less than 2% of cycle life annually. The financial benefit typically far outweighs any marginal degradation impact. Tesla and most program operators explicitly say VPP participation is within the battery's design parameters.

What is ConnectedSolutions and how does the $225/kW rate work? ▼

ConnectedSolutions is a demand-response program run by New England utilities (Eversource CT/MA, National Grid MA, Unitil MA/NH) that pays battery owners up to $225 per kilowatt of enrolled capacity per summer season (May–October). A 10 kWh battery with a 5 kW inverter enrolls 5 kW and can earn up to $1,125 per summer. Events happen on hot weekday afternoons — typically 10–15 events per summer lasting 2–4 hours each. The payment is based on enrolled capacity, not energy dispatched, making it particularly valuable for batteries with high power output relative to capacity. Enrollment typically requires a smart inverter or compatible battery system.

Are there VPP programs available outside California and New England? ▼

Yes, VPP programs are expanding rapidly across the US and internationally. In the US: Tesla VPP operates in CA, TX, AZ, VT, MA; OhmConnect is available in CA, TX, NY; Green Mountain Power covers Vermont; Sunrun Sunrun Energy Services operates in multiple states; Swell Energy aggregates batteries in several markets. Internationally, programs exist in Australia (Reposit Power, Tesla VPP SA), the UK (Octopus Powerloop, Kaluza), and Germany (Sonnen Community). Check with your battery installer or utility for local programs — many utilities are launching their own programs as battery adoption accelerates.
