Your home battery is an asset. Most homeowners think of it as a backup device and a bill-reducer. But a growing category of programs turns residential batteries into active grid participants — and pays homeowners for the privilege. Virtual power plants (VPPs) are among the most compelling financial opportunities in residential energy, and they’re expanding rapidly.

What Is a Virtual Power Plant?

A virtual power plant is an aggregation of distributed energy resources — home batteries, smart thermostats, EV chargers, solar inverters — coordinated by software to behave, from the grid’s perspective, like a single large power plant. When the grid needs extra power or reduced demand, the VPP operator signals thousands of devices simultaneously, producing a coordinated response that can be measured in megawatts.

Traditional power plants are physical facilities — gas peakers, coal plants, hydroelectric dams. They are expensive to build, slow to permit, and generate emissions. VPPs are virtual: they harness existing capacity that’s already distributed throughout the grid. The economics are fundamentally different. A utility that pays homeowners $300 per year each to access 20 kWh of storage capacity across 10,000 homes has acquired 200 MWh of dispatchable storage at a fraction of the cost of building a peaker plant.

Types of Grid Services

VPP programs provide different types of grid services, each with different compensation structures:

Demand Response: Utilities dispatch events during peak demand periods and pay enrolled customers for reducing their grid draw. With a battery system, demand response is handled automatically — you discharge stored energy to zero out your grid consumption during events. Compensation is typically $0.50–$1.50 per kWh of reduction, with programs running 10–50 events per year.

Frequency Regulation: Grid frequency must be maintained at exactly 60 Hz. When generation and load are momentarily out of balance, frequency deviates. Battery systems can respond in milliseconds to absorb or inject power and correct frequency. This is the highest-value service — regulation capacity can pay $3–$8 per kWh per month in active markets.

Spinning Reserve: Utilities maintain reserve capacity that can ramp within 10 minutes in case a generator unexpectedly trips offline. Batteries are ideal spinning reserve because they can respond in seconds, not minutes. Compensation varies by market but typically ranges from $5–$15 per kW per month.

Energy Arbitrage on Behalf of the Utility: Some utilities operate programs where they charge your battery during off-peak grid surplus (often negative-price periods) and discharge during peak periods. The utility captures the spread; you receive a participation incentive.

Active Programs in 2026

VPP programs have expanded dramatically since 2022. Here’s a snapshot of active programs in key markets:

  • California (Pacific Gas & Electric, SCE, SDG&E): Multiple active VPP programs with compensation of $50–$250 per year per enrolled system
  • Massachusetts (Eversource, National Grid): Connected Solutions program pays $150–$300 per kW of enrolled capacity seasonally
  • New York (Con Edison): ActiveCon program with $3/kW-month compensation and bonus events
  • Texas (ERCOT market): Retail providers offer VPP enrollment with bill credits; some offer real-time participation in wholesale markets
  • Vermont (Green Mountain Power): One of the most mature VPP programs in the country, paying $850/year for 10 kWh enrolled capacity

What Does Participation Actually Require?

VPP enrollment typically requires three things: a compatible battery system connected to the internet, enrollment in the utility’s program (usually done through an online portal), and agreement to allow the utility or VPP operator to dispatch your battery within agreed parameters.

Those parameters are important. A well-designed program — and Kora’s VPP integrations — will always respect your minimum battery reserve. If you’ve set a 20% backup reserve, the VPP cannot dispatch your battery below that level, even during a major grid event. Your home’s protection takes absolute priority over grid services revenue.

Dispatch events typically last 30 minutes to 4 hours and occur 10–50 times per year. On most days, VPP enrollment has zero impact on how your battery operates. The AI handles enrollment transparently — it tracks available capacity, honors your reserve settings, and maximizes your VPP revenue while ensuring your backup capability is never compromised.

The Revenue Math

Using Massachusetts’ Connected Solutions program as an example: the program pays approximately $0.25–$0.50 per kW of demand response capacity per event, with roughly 30–50 events per summer season. A 16 kWh battery capable of providing 5 kW of demand response participation over 40 events at $0.35/kW earns approximately $70 per summer.

That sounds modest — but stack it with the TOU arbitrage savings ($600–$1,100/year) and the program starts to look more interesting as a component of total system return. Vermont’s more generous program pays $850/year for 10 kWh enrolled, making VPP revenue the largest single financial benefit of battery storage in that market.

As VPP markets mature and more utilities compete for residential flexibility, program compensation is generally trending upward. Early enrollees often lock in advantageous terms that new participants cannot access.

The Grid Services Flywheel

The long-term significance of VPP programs extends beyond the individual homeowner’s economics. Every megawatt of residential battery capacity enrolled in a VPP program reduces the need for utilities to build new peaker plants. Those plants are the most expensive, least efficient, and most polluting generation assets on the grid — they run only a few hundred hours per year and emit disproportionate pollution.

When residential batteries absorb excess renewable generation and discharge during peak demand, they smooth the grid’s variability and allow higher penetrations of solar and wind. The homeowner earns revenue. The utility avoids peaker plant construction. The grid becomes cleaner and more reliable. This is the virtuous cycle that VPP programs are designed to create at scale.

Getting Started

If you have a Kora system, VPP enrollment is handled directly through the Power App. Navigate to Programs, select your utility from the list, review the terms, and enroll. The system handles all dispatch communication automatically and provides a detailed revenue report in the app each month.

If you’re evaluating a battery system and live in a market with an active VPP program, factor the potential enrollment revenue into your payback calculation. In the best markets, VPP revenue alone can reduce payback period by 2–3 years.
