The major U.S. automakers are catching up on Tesla’s power game.
It was my first truck-powered cocktail party.
General Motors had gathered journalists at a Beverly Hills mansion last week for a vehicle-to-home show and tell. GM’s engineers outfitted the garage with all the components needed for an electric vehicle’s battery to back up the house’s power supply. Then they tripped the circuit breaker to cut off the home from grid power and let the plugged-in Chevy Silverado electric pickup run the home’s lights and other electrical systems for the remainder of the gathering.
V2H tech, as it’s known, will be available in the top-of-the-line Silverado EV First-Edition RST that will begin deliveries in the middle of this year, making the Chevy competitive with its natural rival, the electric Ford F-150 Lightning. The Ford, released just two years ago, was one of the first American EVs to use bidirectional charging to let the vehicle battery to power the home. Soon, though, V2H may be commonplace: GM promises to put it not just in all its new electric trucks, but also in all the new EVs it’s building on the new Ultium platform by 2026, which may force other automakers to follow suit.
These moves aren’t just about a new feature to highlight in truck commercials. In the EV age, car companies have to become energy companies, too.
GM has spun off a whole new group, GM Energy, just to handle all the ways its electric Chevrolets and Cadillacs will interface with the integrated home. In its simplest guise, V2H, the system requires several boxes mounted to the wall in the garage. There’s a “dark start” battery to make sure the backup system has enough juice to get going again in case of power outage; and there’s an inverter to turn the DC electricity from a truck battery into AC for the house. The GM’s PowerShift charger refills the EV battery, but also allows energy to flow both ways.
That’s just the beginning. GM Energy is also introducing stackable PowerBank batteries a person could keep in their basement or garage. The company will add the ability to integrate solar panels into the system later in 2024, according to Chief Revenue Officer Aseem Kapur.
With these new pieces in place, energy can move around a person’s home in any direction. On a very sunny day, excess solar energy could be routed to the house’s battery stack — just as, at the scale of the utility grid, excess power from solar farms is stashed away in batteries during the afternoon to provide energy at night. The home’s battery stack could be used to back up the power supply in case of outage (just in case your Silverado isn’t plugged in at the time).
And the next stage is coming soon. Kapur said that by 2026, GM’s Ultium EVs will be equipped with vehicle-to-grid — V2G — capability. Today, some residents with home energy storage are using their stashed kilowatt-hours to participate in a virtual power plant; they engage in energy arbitrage by storing electricity when it’s cheap and selling it back to the grid when it’s expensive, making money in the process. V2G represents one step further. EVs that can talk to the grid could help to prevent blackouts and let their drivers engage in energy arbitrage using the battery in their pickup truck while it’s parked in the driveway. (For what it’s worth, Kapur told me the charging and discharging cycles from doing this are much easier on the EV’s battery life than the herky-jerky, stop-and-start nature of driving.)
It turns out that electrification is a multi-pronged revolution in the car business. First came the cars. As Heatmap has reported, Tesla’s enormous lead in selling EVs has eroded as the big companies’ electric offerings have improved and Musk became distracted with Twitter, Cybertrucks, and robotaxis.
The energy business marks another way the old-fashioned car companies are finally catching up to Elon Musk. Tesla for years has sold its own solar panels and Powerwall home batteries. It set up a virtual power plant in Texas to allow its solar and battery customers to make money on the energy markets. Suddenly, Detroit is moving into that space.
GM Energy’s home-of-the-future system will be sold as an added feature for people who buy an EV like the Silverado and want to back up their home electricity, but anybody — Chevy driver or no — could buy into the interconnected residential energy system. Ford’s Home Integration System performs the same function. At CES in January, Kia demonstrated an entire connected home to evangelize the potential of V2H and V2G. It won’t be long before all the major automakers have a similar solution on offer.
Of course, the home is just one part of the new energy ecosystem. In the days of gasoline, the oil companies controlled refueling and filled the country with Chevron and Texaco stations on every corner. But in the electric age, the carmakers are trying to exert more control on that market. Tesla appeared to grab the early lead in fast-charging stations, then it convinced the other automakers — GM and Ford included — to adopt its plug standard in their EVs so their customers could take advantage of Tesla’s charging network.
But with recent mass layoffs to Tesla’s Supercharger team, that advantage is in doubt. Musk may have opened the door for the other carmakers to swoop in. GM was among seven automakers that, earlier this year, pledged to build out 30,000 new fast-charging stations of their own by the decade’s end. As car companies continue to build out their energy businesses, they’ll keep creeping up on Tesla’s territory there. Then Musk really better hope that the robotaxi pans out.

A conversation with VDE Americas CEO Brian Grenko.
This week’s Q&A is about hail. Last week, we explained how and why hail storm damage in Texas may have helped galvanize opposition to renewable energy there. So I decided to reach out to Brian Grenko, CEO of renewables engineering advisory firm VDE Americas, to talk about how developers can make sure their projects are not only resistant to hail but also prevent that sort of pushback.
The following conversation has been lightly edited for clarity.
Hiya Brian. So why’d you get into the hail issue?
Obviously solar panels are made with glass that can allow the sunlight to come through. People have to remember that when you install a project, you’re financing it for 35 to 40 years. While the odds of you getting significant hail in California or Arizona are low, it happens a lot throughout the country. And if you think about some of these large projects, they may be in the middle of nowhere, but they are taking hundreds if not thousands of acres of land in some cases. So the chances of them encountering large hail over that lifespan is pretty significant.
We partnered with one of the country’s foremost experts on hail and developed a really interesting technology that can digest radar data and tell folks if they’re developing a project what the [likelihood] will be if there’s significant hail.
Solar panels can withstand one-inch hail – a golfball size – but once you get over two inches, that’s when hail starts breaking solar panels. So it’s important to understand, first and foremost, if you’re developing a project, you need to know the frequency of those events. Once you know that, you need to start thinking about how to design a system to mitigate that risk.
The government agencies that look over land use, how do they handle this particular issue? Are there regulations in place to deal with hail risk?
The regulatory aspects still to consider are about land use. There are authorities with jurisdiction at the federal, state, and local level. Usually, it starts with the local level and with a use permit – a conditional use permit. The developer goes in front of the township or the city or the county, whoever has jurisdiction of wherever the property is going to go. That’s where it gets political.
To answer your question about hail, I don’t know if any of the [authority having jurisdictions] really care about hail. There are folks out there that don’t like solar because it’s an eyesore. I respect that – I don’t agree with that, per se, but I understand and appreciate it. There’s folks with an agenda that just don’t want solar.
So okay, how can developers approach hail risk in a way that makes communities more comfortable?
The bad news is that solar panels use a lot of glass. They take up a lot of land. If you have hail dropping from the sky, that’s a risk.
The good news is that you can design a system to be resilient to that. Even in places like Texas, where you get large hail, preparing can mean the difference between a project that is destroyed and a project that isn’t. We did a case study about a project in the East Texas area called Fighting Jays that had catastrophic damage. We’re very familiar with the area, we work with a lot of clients, and we found three other projects within a five-mile radius that all had minimal damage. That simple decision [to be ready for when storms hit] can make the complete difference.
And more of the week’s big fights around renewable energy.
1. Long Island, New York – We saw the face of the resistance to the war on renewable energy in the Big Apple this week, as protestors rallied in support of offshore wind for a change.
2. Elsewhere on Long Island – The city of Glen Cove is on the verge of being the next New York City-area community with a battery storage ban, discussing this week whether to ban BESS for at least one year amid fire fears.
3. Garrett County, Maryland – Fight readers tell me they’d like to hear a piece of good news for once, so here’s this: A 300-megawatt solar project proposed by REV Solar in rural Maryland appears to be moving forward without a hitch.
4. Stark County, Ohio – The Ohio Public Siting Board rejected Samsung C&T’s Stark Solar project, citing “consistent opposition to the project from each of the local government entities and their impacted constituents.”
5. Ingham County, Michigan – GOP lawmakers in the Michigan State Capitol are advancing legislation to undo the state’s permitting primacy law, which allows developers to evade municipalities that deny projects on unreasonable grounds. It’s unlikely the legislation will become law.
6. Churchill County, Nevada – Commissioners have upheld the special use permit for the Redwood Materials battery storage project we told you about last week.
Long Islanders, meanwhile, are showing up in support of offshore wind, and more in this week’s edition of The Fight.
Local renewables restrictions are on the rise in the Hawkeye State – and it might have something to do with carbon pipelines.
Iowa’s known as a renewables growth area, producing more wind energy than any other state and offering ample acreage for utility-scale solar development. This has happened despite the fact that Iowa, like Ohio, is home to many large agricultural facilities – a trait that has often fomented conflict over specific projects. Iowa has defied this logic in part because the state was very early to renewables, enacting a state portfolio standard in 1983, signed into law by a Republican governor.
But something else is now on the rise: Counties are passing anti-renewables moratoria and ordinances restricting solar and wind energy development. We analyzed Heatmap Pro data on local laws and found a rise in local restrictions starting in 2021, leading to nearly 20 of the state’s 99 counties – about one fifth – having some form of restrictive ordinance on solar, wind or battery storage.
What is sparking this hostility? Some of it might be counties following the partisan trend, as renewable energy has struggled in hyper-conservative spots in the U.S. But it may also have to do with an outsized focus on land use rights and energy development that emerged from the conflict over carbon pipelines, which has intensified opposition to any usage of eminent domain for energy development.
The central node of this tension is the Summit Carbon Solutions CO2 pipeline. As we explained in a previous edition of The Fight, the carbon transportation network would cross five states, and has galvanized rural opposition against it. Last November, I predicted the Summit pipeline would have an easier time under Trump because of his circle’s support for oil and gas, as well as the placement of former North Dakota Governor Doug Burgum as interior secretary, as Burgum was a major Summit supporter.
Admittedly, this prediction has turned out to be incorrect – but it had nothing to do with Trump. Instead, Summit is now stalled because grassroots opposition to the pipeline quickly mobilized to pressure regulators in states the pipeline is proposed to traverse. They’re aiming to deny the company permits and lobbying state legislatures to pass bills banning the use of eminent domain for carbon pipelines. One of those states is South Dakota, where the governor last month signed an eminent domain ban for CO2 pipelines. On Thursday, South Dakota regulators denied key permits for the pipeline for the third time in a row.
Another place where the Summit opposition is working furiously: Iowa, where opposition to the CO2 pipeline network is so intense that it became an issue in the 2020 presidential primary. Regulators in the state have been more willing to greenlight permits for the project, but grassroots activists have pressured many counties into some form of opposition.
The same counties with CO2 pipeline moratoria have enacted bans or land use restrictions on developing various forms of renewables, too. Like Kossuth County, which passed a resolution decrying the use of eminent domain to construct the Summit pipeline – and then three months later enacted a moratorium on utility-scale solar.
I asked Jessica Manzour, a conservation program associate with Sierra Club fighting the Summit pipeline, about this phenomenon earlier this week. She told me that some counties are opposing CO2 pipelines and then suddenly tacking on or pivoting to renewables next. In other cases, counties with a burgeoning opposition to renewables take up the pipeline cause, too. In either case, this general frustration with energy companies developing large plots of land is kicking up dust in places that previously may have had a much lower opposition risk.
“We painted a roadmap with this Summit fight,” said Jess Manzour, a campaigner with Sierra Club involved in organizing opposition to the pipeline at the grassroots level, who said zealous anti-renewables activists and officials are in some cases lumping these items together under a broad umbrella. ”I don’t know if it’s the people pushing for these ordinances, rather than people taking advantage of the situation.”
