Does my vehicle support vehicle-to-home?

That is the first thing to establish and the answer is model-specific rather than brand-specific. Support varies by nameplate, by model year, and sometimes by trim and software version. We confirm it against your actual vehicle before any equipment is specified, because the failure mode here is buying a system that waits indefinitely for a capability the car does not have.

How does this compare to a home battery?

The pack in a full-size electric truck holds substantially more energy than a typical fixed home battery, and you have already paid for it. The trade-offs are that the energy leaves when you drive, the output is capped by the equipment rather than the pack, and the whole category is less mature. Some households do both — the battery for routine outages, the vehicle for a long one.

Will my utility allow it?

Generally yes, subject to an interconnection agreement, and the process differs across the six providers serving this area. A municipal utility, a cooperative and a delivery utility each handle it differently. We establish which one serves your meter and what it requires before quoting, because that approval usually sets the schedule.

Is it worth doing yet?

Honestly, sometimes not — and we will say so. Where the vehicle, the equipment and the utility all line up, it works well and the economics are good because the battery is already bought. Where any of the three is not ready, waiting is the better advice. We would rather tell you that than sell you a system whose value depends on a future firmware release.

Bidirectional Charging & Vehicle-to-Home in Austin

Using the car's pack to carry the house. A large truck battery holds considerably more than a typical home storage unit, and it is already in the driveway.

Bidirectional charging runs power the other way: out of the vehicle and into the house. The appeal is straightforward — the largest battery most households own is sitting in the driveway, and during an outage it is doing nothing.

The honest position on maturity

This is a genuinely promising category and a genuinely uneven one. Support depends on the specific vehicle, the specific equipment, and your utility’s willingness to interconnect it. Those three do not always align, and the marketing around the category is well ahead of the reality in many cases.

So the first piece of work is not a quote. It is establishing whether your car can actually do this, today, with equipment you can actually buy. We will tell you plainly if the answer is no, and we would rather do that than install hardware that becomes useful at some unspecified point in the future.

Why the numbers are attractive when it does work

A full-size electric truck carries a pack several times the capacity of a common fixed home battery. In an extended outage that difference is not marginal — it is the difference between rationing and simply continuing.

Two qualifications matter. First, output is limited by the bidirectional equipment’s rating, not by pack capacity, so a very large battery does not mean a very large simultaneous draw. Second, the energy leaves when the vehicle does, which is a real constraint during exactly the sort of regional event where you might also want to drive somewhere.

That is why some households end up with both: a modest fixed battery for the routine outage, and the vehicle available for the long one.

What the installation involves

Compatible equipment matched to the specific vehicle. A critical-loads subpanel, on the same reasoning as a fixed battery — you define what the vehicle is carrying rather than asking it to hold up the whole house. Transfer equipment that separates the house from the grid correctly during an outage, so the system cannot back-feed lines that crews believe are dead. Conductors sized to the equipment’s rated output.

Where a charging circuit already exists or is planned, this gets designed alongside it rather than bolted on afterwards. The load calculation covers the whole picture once.

Interconnection across six utilities

Every system that can operate in parallel with the grid needs the serving utility’s agreement, and this service area has six of them with six sets of requirements. Austin Energy, Georgetown and San Marcos are municipal. Pedernales and Bluebonnet are cooperatives. Oncor is a delivery utility on the competitive market.

Which one serves your meter is decided by service territory rather than by your postal address, so we confirm it from the bill before quoting a schedule. On this category in particular, the approval is usually the long pole.
