The battery already sitting in your driveway

Most people have heard the term V2G and assumed it was a concept from a trade show. It is not. The technology exists, the vehicles exist, and Canada's first real-world pilots are already running. What is still catching up is the infrastructure that makes it easy for ordinary drivers to participate, and that gap is closing faster than most people realize.

But first, the vocabulary. It all sits under one umbrella called bidirectional charging, which simply means electricity can flow both into your car and back out of it. That single idea shows up in three forms, and they get used interchangeably when they should not be.

V2L stands for Vehicle-to-Load. The simplest version. Your car powers devices directly through an outlet built into the vehicle. No special charger required. Many EVs already do this, including the Hyundai Ioniq 5, the Kia EV6, and the Ford F-150 Lightning.

V2H stands for Vehicle-to-Home. Your car powers your house. During a blackout, your EV becomes your backup generator — except it is silent, already in your garage, and holds enough energy to run your essential appliances for a day or more. The Ford F-150 Lightning's 131 kWh battery at 9.6 kW of output can power an average Canadian home for roughly three days.

V2G stands for Vehicle-to-Grid. The full version. Energy flows from your car battery back into the public electrical grid during periods of peak demand. Your utility pays you — in credits, reduced rates, or direct payment — for that stored energy. This is what grid operators get excited about, because millions of EVs participating would create a distributed battery network across the country.

All three are forms of bidirectional charging. Not every EV that supports V2L also supports V2H, and not every V2H vehicle yet supports V2G, so confirm exactly what a given model can do before you buy or lease. If you are wondering which one matters to you: V2L is everyday convenience, V2H is backup power for your home, and V2G is the one that can eventually pay you.

Start with the number that matters most. What could you actually earn?

Dr. Jeff Dahn, Canada's most cited battery researcher at Dalhousie University in Halifax, ran a real-world V2G trial and reported that each participating vehicle delivered or stored roughly half a megawatt-hour over six months. At Nova Scotia's electricity rates, that works out to about $230 per year. Plug in more often, allow wider charge ranges, and that climbs. Dahn's projection for a fully participating vehicle over ten years is around $10,000 in cumulative earnings at $0.20 per kilowatt-hour.

The ceiling in other markets is higher. A University of Delaware study found that a V2G-enabled passenger EV could earn up to $3,359 per year providing grid services under optimal conditions. Canada is not there yet. But the direction is clear, and the early Canadian numbers are real, not modelled.

The more immediate value for most Canadian households is V2H. Power outages are a fact of life in every province — ice storms in Ontario and Quebec, windstorms in BC, grid strain across the Prairies during extreme heat. A mid-size EV battery of 70 to 80 kWh connected to your home panel is a more capable backup than most gas generators, without the fuel cost, the noise, or the carbon.

Neither of these things requires you to actively manage anything once the system is set up. You set your minimum battery level — say 30 percent so you always have range for the next day — and everything else runs in the background.

What you need to make this work:

A V2G or V2H-capable EV. A bidirectional Level 2 charger installed by a certified electrician. For V2H, coordination with an electrician on your panel connection — no utility approval required. For V2G, enrollment in a utility program, currently available in pilot form in BC and expanding nationally.

Canada is not starting from zero on this. It just has not been loud about it.

In September 2025, BC Hydro became the first Canadian utility to run a real-world field test of V2G technology, not a lab simulation but electric school buses operating on regular route schedules while sending energy back to the grid during peak demand. The two-month pilot built on an earlier 2023 lab demonstration, and BC Hydro has said it plans to expand charging hubs across the province from here. Each bus holds up to 200 kilowatt-hours of storage, enough to power approximately 75 single-family homes for nearly two hours. BC Hydro partnered with Lynch Bus Lines and Fuse Power Management on the $1.1 million initiative, with federal support through PacifiCan.

In Toronto, Natural Resources Canada funded a real-world Vehicle-to-Building demonstration at two downtown condominiums. SWTCH Energy deployed bidirectional chargers that stored energy through parked Nissan Leafs during off-peak hours and redistributed it back into the buildings during peak periods. The conclusion: V2G technology is operationally reliable and capable of delivering real energy services in an urban residential context.

In April 2026, at the kWh Summit in Toronto, experts from BC Hydro, Dunsky Energy, and utilities across the country reached a clear consensus. The technology is ready. What remains is coordination: standardized communication protocols between automakers and utilities, a national playbook, and regulatory clarity.

BC Hydro already publishes guidance for residential customers on connecting bidirectional vehicles to the grid. It draws a clear line between V2H, which needs no utility coordination, and V2G, which does, because sending power back to the public grid falls under the rules for distributed energy resources, the small scattered power sources such as home solar and batteries that feed into the grid. That kind of practical, customer-facing clarity at the utility level is new. It matters.

Canada's fragmented policy landscape is the real barrier, not the technology. The CSA Group's October 2025 report on vehicle-grid integration was direct about this: the hardware and vehicles exist, but standardized communication protocols between utilities and automakers do not yet exist nationally. Different provinces, different utilities, different rules.

The path forward is already being drawn. At the 2026 kWh Summit, BC Hydro's senior program manager called for a national V2G playbook — a unified set of standards that would let any utility in any province implement V2G without starting from scratch. Remove the uncertainty for customers and industry, and the technology does the rest.

The federal zero-emission vehicle (ZEV) targets give this urgency. Canada is projecting 4.6 million electric vehicles on the road by 2030 and 12.4 million by 2035. At that scale, V2G participation would represent one of the largest distributed energy storage networks ever assembled — not built by utilities, but by ordinary drivers parking in driveways and garage stalls across the country.

The honest timeline for a residential V2G program you can enroll in from your phone, in most Canadian provinces, is two to four years. Knowing about it now and factoring bidirectional capability into your next vehicle purchase puts you ahead of that curve. This is the kind of specification that will not appear in a brochure until the infrastructure catches up.
