Is V2G worth planning for at your depot yet?
For most depots, not yet as a core feature — but specifying V2G-capable kit can be a cheap hedge. Here's how to judge it.

Vehicle-to-grid is promising, but “promising” and “worth building around today” are different things. Here’s how to judge it for your depot.
The case for waiting
For most operators, V2G isn’t yet a reason to change the plan. The vehicles and chargers that support it are still a minority and cost more, and the commercial arrangements to make it pay are early. Building your project around V2G today means betting on pieces that aren’t fully in place — a risk most depots don’t need to take when smart charging already delivers the core value.
The case for a cheap hedge
That said, if V2G-capable equipment is available at little or no premium when you’re buying anyway, specifying it can be a sensible hedge — you’re ready if the economics mature, at low cost. The line to hold is little or no premium: paying a large one on today’s uncertain numbers is hard to justify.
What tips the balance
V2G becomes genuinely worth planning for when your vehicles and chargers support it as standard, and when flexibility payments clearly justify the extra hardware and the battery wear from cycling. Fleets that sit idle for very long stretches, with the right kit, are where it lands first.
The pragmatic stance
Compare it honestly with a stationary battery, which does a similar job reliably today. For now: get the fundamentals right, hedge cheaply if you can, and revisit V2G as vehicles, chargers and markets catch up. It’s a “watch and stay ready” call, not a “build now” one.
