Could Your Home Battery Make You Money? Virginia's Virtual Power Plant Explained
What if your home could store electricity when demand is low, use that power when electricity is more expensive — and potentially get paid for helping the grid when demand is at its highest?
It sounds futuristic, but Virginia is already moving in that direction.
Dominion Energy Virginia is preparing to launch a new Virtual Power Plant pilot that could connect home batteries, EV chargers and other smart energy technologies across the Commonwealth.
And it could change the way Hampton Roads homeowners think about electricity.
What Is a Virtual Power Plant?
A traditional power plant generates electricity at one large facility.
A Virtual Power Plant, or VPP, takes a very different approach.
It connects thousands of smaller energy resources — such as home batteries, managed EV chargers and smart thermostats — and coordinates them so they can help support the electrical grid together.
Think about a home battery in Newport News.
By itself, it's simply one battery.
Connect thousands of batteries and other smart devices throughout Virginia, and suddenly those individual systems can collectively become a significant energy resource.
Virginia's new VPP initiative allows Dominion Energy Virginia to pilot up to 450 megawatts of these distributed energy resources.
That's no longer a small experiment.
Buying Power Low and Using It High
This is where things get especially interesting for homeowners.
Electricity demand changes throughout the day. There are periods when demand is relatively low and other times — think hot summer afternoons when air conditioners are running everywhere — when demand on the grid climbs dramatically.
A home battery creates the ability to separate when you get electricity from when you use it.
Instead of pulling all your electricity from the grid during periods of high demand, a battery can store energy and make it available later.
This basic concept is sometimes called energy arbitrage — taking advantage of differences between lower-cost and higher-cost periods.
As Virginia develops its Virtual Power Plant programs, participating customers may also have opportunities to receive compensation for allowing eligible devices to provide specific services to the grid.
The exact programs, rates and eligibility requirements are still being developed, so this isn't as simple as buying electricity cheap tonight and selling it back tomorrow for a guaranteed profit.
But the direction is important.
Your home could become an active participant in how electricity is managed.
Could Your EV Become Part of a Virtual Power Plant?
Here's where this gets particularly interesting for electrification.
Virginia's VPP law doesn't just address home batteries.
It specifically allows technologies including managed EV charging to participate in the pilot.
Imagine thousands of EVs plugged in throughout Hampton Roads.
They don't all need to charge at exactly the same time.
Smart load management could shift some charging away from periods when electrical demand is highest while still making sure vehicles are ready when their owners need them.
Combine EV charging with battery storage, smart controls and other connected technology, and a home starts looking very different from the home electrical system of 20 years ago.
It's becoming an energy system.
What About Backup Power During a Hampton Roads Storm?
For Hampton Roads homeowners, there's another important part of this conversation: resilience.
Battery storage can provide backup power when the grid goes down — an obvious consideration in a region accustomed to hurricanes, tropical storms and severe weather.
So what happens if your battery is participating in a VPP?
Customer control is an important part of Virginia's developing program. The law specifically requires consideration of limits on grid events and conditions that allow participating customers to opt out.
Electrification Is Changing the Role of Your Electrical System
EV chargers. Battery storage. Smart panels. Load management. Solar. Virtual Power Plants.
These technologies may sound like separate subjects, but they're increasingly becoming pieces of the same system.
That's electrification.
And it's changing what homeowners and businesses need from their electrical infrastructure.
At Go Green Electric, we believe the conversation shouldn't start with the newest piece of technology.
It should start with the electrical system behind it.
Can your panel support it? How much capacity is available? How should loads be managed? How might an EV charger and battery work together? And how do you prepare your home for technologies that may be coming next?
The future of electricity isn't just about how much power we use.
It's increasingly about when we use it, where we store it, and how intelligently we manage it.
