July was a strong month for Amber's V2X fleet. More chargers connected, a record spike day for exports, and most of the value coming from customers using stored EV energy to power their homes. Below is what drove each of those results, and what they suggest about where V2X is heading.
What happened across the fleet this month
Across July, the fleet discharged 6,919 kWh from EV batteries, generating $1,888 in value. Most of that came from vehicle-to-home (V2H), where stored EV energy powers the house instead of drawing from the grid. The rest came from vehicle-to-grid (V2G), exporting energy back to the grid at wholesale prices.
The numbers
- Fleet size: 54 connected chargers
- Period: July 2026
ENERGY IN, ENERGY OUT
- Total charged into vehicles: 16,739 kWh. Of that, 10,474 kWh came from the grid and 6,265 kWh from home solar and batteries.
- Total discharged from vehicles: 6,919 kWh. This is the energy that flowed back out of EV batteries for useful purposes. 4,724 kWh powered homes via V2H, and 2,195 kWh was sent back to the grid via V2G.
WHAT IT MEANS IN DOLLARS
- Value returned via V2H + V2G: $1,888. The financial benefit of using that stored energy smartly. $1,457 came from avoiding grid electricity purchases through V2H (30.8 c/kWh avoided import), and $430 was earned from grid exports via V2G (19.6 c/kWh export credit).
OUR LEARNINGS
Value concentrated in V2H
V2H carried 68% of discharged energy but 77% of total value. That's because powering your home replaces electricity you'd otherwise buy at retail prices, while V2G exports earn the wholesale rate, so each kWh used at home is worth more.
Export value concentrated in one event
Wholesale prices spiked on the evening of 30 July, and the fleet was ready for it, producing the single largest V2G earning day of the month. It's a good reminder of what V2G can capture when the moment's right - even if most days are quieter on the export side.
What this means for an average connected home
Spread across the 54 connected sites, the average home benefited $35 in July from vehicle-based flows alone. Of that, roughly $27 came from V2H and $8 from V2G, all from from energy that would otherwise have sat unused.
The more available a car is, the more it earns. Vehicles plugged in for most of the day and through the evening peak are getting the most out of it. That pattern is most common in households with low travel needs, where the car sits on the charger between short trips. A car that is home at 6pm can run the house through the most expensive hours of the day.
Sites with high availability generated over $200 in value per month - a strong sign of what V2G can deliver as more households find the setup that works for them.
WHAT WE'RE WATCHING
As more chargers connect, events like the 30 July spike become worth more to capture, and the coming months should be even more interesting.
Spring historically brings record levels of negative daytime prices, as rooftop solar floods a low-demand grid. It also brings tighter periods when large generators come offline for shoulder-season maintenance, with genuine volatility typically building from late spring into summer.
That's good news for V2X. A wider gap between cheap and expensive periods means more room to charge low and discharge high, cheaper charging in the middle of the day, and more valuable discharging when the evening gets tight. We'll continue to share progress on how the V2H and V2G split moves through August and September.
The fleet's growing, and so is the value it's generating. If you want to be part of it, join the waitlist, or see what it looks like in practice in Francis' story, one of our earliest V2G customers using his EV to power his farm and sell energy back to the grid.
