In early March, sturdy winds introduced down timber and energy traces within the Nashville space, leaving hundreds of properties with out energy. However about 20 miles exterior town an electrical pickup truck fed vitality to John and Rachelle Reigard’s house, conserving their lights on.

“You possibly can have a look at all the homes round us, and so they’re all off,” mentioned Mr. Reigard, who purchased the pickup, a Ford F-150 Lightning, greater than a yr in the past. “Lots of people ask the query: ‘How do you may have energy?’”

The Reigards are a part of a small group of pioneers utilizing the batteries of their electrical autos as a supply of backup energy for his or her properties. Power and auto specialists anticipate many extra folks to do the identical within the coming years as auto and vitality corporations make it simpler for folks and companies to faucet the vitality in electrical automobiles for greater than driving.

Electrical grids are more and more straining and buckling throughout excessive climate linked to local weather change, together with in prolonged warmth waves, intense storms and devastating floods. Many individuals have purchased mills or house photo voltaic and battery methods, typically at nice expense.

To some folks, electrical autos are a greater choice as a result of they’ll serve a number of capabilities. One other huge benefit: The battery in an F-150 Lightning or the electrical Chevrolet Silverado pickup, which is anticipated to go on sale this yr, can retailer much more vitality than house batteries which might be typically put in with rooftop photo voltaic panels. Pair an electrical truck with a house photo voltaic system, the pondering goes, and a household might preserve the lights on for days and even weeks.

The usage of electrical autos as a supply of energy has intrigued electrical utility executives, together with Pedro Pizarro, who heads the board of the Edison Electrical Institute, the business’s predominant commerce group, and is the chief govt of Edison Worldwide, which offers energy to hundreds of thousands of properties and companies in Southern California.

Mr. Pizarro’s firm and different utilities are testing whether or not it’s sensible and secure to ship energy from electrical autos to the grid.

By absorbing energy when it’s ample and releasing it when it’s scarce, electrical autos, he mentioned, might function “an even bigger rubber band to soak up the shocks and handle them each day and week to week.”

Larger use of electrical autos on this means must also enable utilities and owners to cut back planet-warming emissions by relying extra on renewable sources of vitality like photo voltaic and wind that present energy intermittently.

For now, few electrical autos can present backup energy. However executives at Tesla, the dominant electrical automotive firm, and different automakers have mentioned they’re engaged on updates that may allow many extra automobiles to take action.

When the ability goes out within the Reigards’ neighborhood in Mount Juliet, Tenn., their truck provides sufficient electrical energy to maintain the lights on, run 4 fridges and function a fan in a natural-gas-fueled heating system. The truck doesn’t preserve their air-conditioning going, however different necessities activate simply minutes after an outage begins.

When the household misplaced energy round Christmas, Ms. Reigard’s mother and father, who had been visiting, had been alarmed as a result of it was freezing exterior. “They began pondering, ‘My gosh, what’s occurring?’” Mr. Reigard mentioned. His response: “Nothing’s occurring. We’re going to be superb.”

The couple have been so happy by their truck that they purchased 10 extra for his or her enterprise, Grade A Building. They estimate that the funding is saving them $300 a month per car as a result of driving on electrical energy prices much less per mile than burning gasoline.

Whereas the vehicles scale back working prices, outfitting the Reigards’ house with {the electrical} gear that lets it obtain energy from the F-150 required hiring specialists and spending hundreds of {dollars}. The couple used Qmerit, an organization that manages the event, set up and upkeep of electrical autos, storage and vehicle-to-home vitality methods.

A handful of elements relay data between the truck and the house’s electrical system, home equipment and lights. As soon as arrange with a house owner’s preferences, the system decides when the truck costs its batteries and when it sends electrical energy again to the home.

However such methods could be difficult, and a few early adopters have encountered issues.

Kevin Dyer, a software program high quality engineer who lives close to Los Angeles, has used electrical autos since 2009 and purchased an F-150 Lightning in September. He wished the truck to assist his household trip out the rolling blackouts which have change into widespread in California in recent times.

“We completed the set up,” Mr. Dyer mentioned. “The truck truly powered my home. That was the high-five second. That’s when issues form of went downhill. It simply mainly works, then shuts off.”

Mr. Dyer, 59, mentioned he hoped a software program replace or one other modest repair would remedy the issue.

Power executives mentioned the business was working to enhance and simplify the expertise to attach electrical automobiles to properties, one thing they mentioned would occur inside just a few years.

Oliver Phillips, chief working officer at Qmerit, mentioned that over time extra folks would be capable to simply mix photo voltaic panels, house batteries and electrical autos. Put collectively, these units will “bulletproof” folks in opposition to energy outages, he mentioned.

Battery-powered autos might finally play a good greater function by offering vitality to the grid when demand for electrical energy exceeds provide, mentioned Gus Puga, proprietor of Airstream Companies, {an electrical}, heating and cooling firm that labored with Qmerit to put in the system on the Reigards’ house.

Some vitality specialists have apprehensive that the expansion of electrical automobiles might pressure grids by tremendously growing demand for vitality. Mr. Puga disagrees: “I consider we’re going so as to add stability to the grid.”

Within the auto business, some specialists have warned that often utilizing automobiles to energy properties or the grid might degrade batteries sooner, lowering vary — the gap that autos can journey on a full cost. However automakers have performed down these dangers.

Ford and Normal Motors are eager on advertising and marketing the flexibility of their battery-powered fashions to individuals who have suffered energy outages or concern blackouts.

“It’s actually a game-changer,” mentioned Ryan O’Gorman, a enterprise growth vitality companies supervisor at Ford. “The truck is a huge energy supply. E.V.s are massive and may energy the home for a number of days.”

Mark Bole, head of vitality connectivity and battery options at G.M., mentioned the corporate deliberate to supply a package deal of units and companies so clients might get essentially the most out of their electrical car. “What we see as completely key’s making it easy and inexpensive for the shopper,” he mentioned.

However Mr. Pizarro, the utility govt, cautioned that vitality and auto corporations nonetheless wanted to refine the expertise permitting automobiles to ship energy to properties and the grid. He expects extra issues to be recognized as extra folks begin to use electrical autos for backup energy.

“It’s the early days,” Mr. Pizarro mentioned. “There can be surprises.”
