DETROIT (AP) — Winter Storm Uri, the multiday freeze that slammed Texas
in February 2021 and pummeled the state's power grid, has been on Kenneth Kovar's mind ever since. Though the resident of New Braunfels, northeast of San Antonio, didn't lose power at the time, he wasn't able to run his septic tank — it is independent from local systems. He had to fill his toilets with water from his backyard pool.So when Kovar, 64, bought a Ford F-150 last fall,
his hope was to be better prepared for any new crisis.
“I was interested in trying to find some sort of power backup situation,” he said.
Now, Kovar has a setup from Ford that allows drivers of certain F-150 models to plug their vehicle directly into their electric meter to power parts of their home during an outage.
It is the latest example of automakers broadly adapting their electrification technologies to the home energy business, especially as demand on the grid increases and sales of electric vehicles slow. Car companies are looking to leverage their multibillion dollar EV investments to tap into a promising market in vehicle, home and grid technology, both for backup power and for supporting electrical grid resiliency.
“They’re trying to look for other businesses that they might sell into,” said Parth Vaishnav, assistant professor of sustainable systems at the University of Michigan.
Drivers of the F-150 PowerBoost hybrid and F-150 Lightning electric pickup trucks can now plug in a one-foot long adapter to a 240-volt outlet onboard. That adapter — which Ford made with company Global Power Products — makes the vehicle compatible to plug into a longer, separate cable. That cable connects to a transfer switch installed directly on one's electric meter.
Through the adapter and cable series, homeowners can connect their vehicle essentially right to their home’s breaker box. The homeowner simply turns on and off which breaker switches they want for which devices they want powered.
“The way we think about it, especially for customers who already have a compatible vehicle is, you already own the power source, it’s in your driveway,” said Amanda Roraff, Ford's grid and energy services business acceleration lead.
The Lightning might provide power for two to three days, depending on what home devices are being used, and the PowerBoost Hybrid, up to five days on a single tank of gas.
The automaker says its solution is a less expensive way to supply backup power. Conventional, diesel-powered portable generators and full-home standby setups require expensive installation, costing several thousands of dollars. This solution, which also requires professional installation at the meter, starts around $1,100.
The setup only applies to about 200,000 vehicles so far, and it is also exclusively for outages. Ford also offers its Home Integration System for bidirectionality, sending power both from the vehicle to the home and from the home to the vehicle, while also being able to feed the grid.
Over 630,000 U.S. vehicles already have this functionality, estimates say, and automakers are rapidly expanding their available options with the goal of full vehicle-to-grid support in the long run.
South Korean auto brand Kia and Wallbox, an EV charging company, have teamed up so that drivers of eligible compatible vehicles can have home power backup during outages or during periods of high demand, to cut their utility use. They can send power back to the grid.
Tesla’s technology is similar — allowing drivers of equipped vehicles to connect to their home using additional Tesla hardware. The Cybertruck provides full vehicle-to-home capability, where other Tesla models can only connect to and power specific devices or appliances.
General Motors is also in the energy space.
A recent partnership with WeaveGrid, for instance, allows homeowners who drive certain GM EVs — and have the automaker’s home system and a proper grid interconnection — to enroll in some grid reliability utility programs. Once an outage is detected, GM’s vehicle-to-home tech has the capability to disconnect one's home from the grid and start supplying power from their GM EV.
“If you can imagine the future as we go forward, it's having the ability — now that we have this single platform — that allows our customer to experience our system,” said Wade Sheffer, vice president of GM energy, “but also can have the full control of the energy.”
Not only is this business critical amid growing grid demand and increasing power outages, experts say automakers need to pivot with the EV market less active under current U.S. federal policy. Pure EV sales in the U.S. year-over-year are down 23.8%, according to a July Cox Automotive report on the first half of 2026. This demonstrates what an asset that EV and hybrid ownership can be.
The tech is not without challenges.
On the industry side, these systems have to undergo third-party testing to ensure they meet safety standards, and the vehicle and the charger need to be programmed to communicate. It also requires the approval of the utility where the capability is being used. It could take years to get an interconnect agreement.
On the customer side, homeowners need to understand their vehicles' abilities and how to self-manage their system. It also just brings another generator of power into the home mix.
Still, experts see opportunity, especially with interest in EV sales high outside of the U.S.
“We already know during an outage, its impact, providing electricity to the home,” said Scott Samuelsen, engineering professor emeritus at the University of California, Irvine. “This is going to become very, very popular.”
