GM’s 250,000 Bidirectional EVs Still Need a Home Kit

General Motors says more than 250,000 of its electric vehicles can send power back toward the grid. The cars already on U.S. roads still need a GM Energy home kit, and a utility program, before any of that power is sold. On June 9 in San Francisco, the company made the fleet the centerpiece of GM Empower. On September 24 the offer that reached California dealers was a free one-way charger and a $15 monthly bill credit.

A Quarter-Million Cars Sit One Kit Short of the Grid

Sterling Anderson, GM’s chief product officer, told the Empower audience there are more than a quarter-million bidirectional-capable GM EVs on the road. Paired with GM’s home energy systems, he said, those vehicles can keep a house running for days in a local outage and are engineered for vehicle-to-grid flow “without requiring additional hardware iterations” on the car. The current work, he added, is software, utility partnerships, and grid protocols.

Wade Sheffer, vice president of GM Energy, put a number on the parked batteries in an open letter to utility executives the same day. Those cars, he wrote, have the energy capacity to help power 120,000 homes for up to one week. The footnote behind that line is more precise than the stage line. It is an illustrative estimate based on about 280,000 GM EVs with V2H hardware in the pack, used with a GM Energy system, and on the EIA’s average U.S. household use of 28.8 kWh a day.

So the 250,000 figure is a talking count of cars that can do the job. The 280,000 figure is the battery-capacity count behind the homes math. Neither count is a count of houses that are actually exporting. The car is ready. The garage usually is not, and neither is the local utility.

THE FLEET ON PAPER

• Talking fleet: More than 250,000 bidirectional-capable GM EVs on U.S. roads, per Anderson and Sheffer on June 9, 2026.
• Capacity case: About 280,000 V2H-capable packs in the letter’s footnote, used to support 120,000 homes for one week.
• PG&E 2030 target: 130,000 GM EVs in the territory, with more than 52,000 joining grid-balancing protocols.
• DTE test: 30 GM employee households in Michigan, according to TJ Tweedle, GM’s V2X lead, speaking at the San Francisco event.

Anderson said bidirectional gear is being treated as a standard from the Chevrolet Equinox EV to the Cadillac Escalade IQ. That is a vehicle claim. The grid claim still runs through a wallbox, an enablement kit, a house that can take the load, and an interconnection file.

The V2H Bundle Still Lists at $8,998

GM Energy’s shop is blunt about what “paired with GM’s home energy systems” means. Bidirectional charging for a capable GM EV requires the PowerShift Charger and the V2H Enablement Kit. On the live store, the two-piece V2H Bundle lists at $8,998 and is marked down to $7,198. The PowerShift Charger alone lists at $1,999 (sale $1,399). The Enablement Kit, for owners who already have the charger, lists at $6,999 (sale $5,599). Select discounts run through September 30, 2026, at 9 p.m. ET.

GM ENERGY HARDWARE ON THE SHOP

Installation, permits, and panel work are extra. The product pages also warn that weather, battery age, how the car is used, and a proper grid hookup all affect how long a house stays lit, and that medical devices should not ride on the kit. The 2026 Chevrolet Silverado EV Max Range is the duration example GM Energy prints: up to five days of backup for a properly equipped home, in a blackout, not as a paid export to the utility.

That is why the software story and the invoice diverge. Over-the-air code can unlock the car. It cannot hang a 80-amp wallbox, rework a panel, or get a utility to accept reverse flow. Owners talking through the install in owner groups keep landing on a five-figure all-in number once labor is included, which is why a discounted $7,198 bundle still behaves like a home-energy purchase rather than a free car feature.

GM Named Two Utility Partners

Anderson named two partners. In Northern California, GM and Pacific Gas and Electric project that by 2030 a localized fleet of 130,000 GM EVs will be on the road, with more than 52,000 of them in grid-balancing protocols. In Michigan, GM is testing with DTE Energy “under real-world conditions.” Sheffer’s letter adds that the Michigan work uses GM employee homes. Tweedle put the live sample at 30 households.

PG&E chief executive Patti Poppe told the Empower audience the grid “desperately needs EVs, particularly bi-directional EVs,” that the utility can optimize, and called EVs “the first flexible demand there’s ever been.” That is the utility case for letting cars charge when power is cheap and send it back when the system is tight. It is also still a speech about a program that has to be designed, tariffed, and interconnected, one service territory at a time.

The rest of the country is the harder map. Form EIA-861, the annual census of U.S. electric utilities, covers about 3,300 utilities. Each one has its own rules for reverse flow, its own engineers, and its own rate book. Sheffer’s letter treats that paperwork as the actual product problem. Streamline enrollment, modernize time-of-use rates so a car can be paid for helping at peak, and collapse interconnection from a custom review into something closer to plug-and-play. Until that happens, a bidirectional Chevrolet in Ohio and a bidirectional Cadillac in Maine are the same car with different electric companies, which is to say they are not the same product.

Which GM EVs Can Power a House?

GM Energy’s site lists 12 V2H-capable nameplates that can feed a properly equipped home through the PowerShift Charger and the Enablement Kit. Hummer EV SUV and Hummer EV SUT are counted separately. The 2027 Chevrolet Bolt EV is on the list, which pulls a high-volume nameplate into a feature that started on trucks and Cadillacs. The long-wheelbase Escalade IQL is not on that list.

V2H-CAPABLE GM EVS ON THE ENERGY SITE

• 2027 Chevrolet Bolt EV: The newest high-volume nameplate on the V2H list.
• 2026 Chevrolet Blazer EV: V2H through the GM Energy bundle; some 2024 cars need a dealer or OTA update first.
• 2026 Chevrolet Equinox EV: Same Ultium path as the Blazer EV, no published vehicle-to-load outlets.
• 2026 Chevrolet Silverado EV: The duration example, up to 5 days on Max Range in a properly equipped home.
• 2026 GMC Hummer EV SUV: Listed for the 2026 model year with the same kit.
• 2026 GMC Hummer EV SUT: Listed separately from the SUV.
• 2026 GMC Sierra EV: Shares the truck path with the Silverado EV.
• 2026 Cadillac Celestiq: On the list, made to order, a tiny slice of the 250,000.
• 2026 Cadillac Vistiq: Three-row Cadillac EV named on the Energy site.
• 2026 Cadillac Escalade IQ: Flagship pack; the IQL body is not listed.
• 2026 Cadillac Optiq: Cadillac’s native NACS crossover, 2025 and 2026.
• 2026 Cadillac Lyriq: Named from 2024 through 2026, with the same 2024 software caveat.

Anderson’s “entire portfolio” line is the strategy. The shop’s 12-nameplate list is the product. A Bolt that can back up a house in 2027 still does it with the same charger and kit as a Silverado EV, which is how GM keeps the hardware business in one stack while the car count grows.

PG&E’s New Bundle Pays for One-Way Charging

The program an owner in Northern and Central California can join without buying the Enablement Kit arrived on September 24, 2026. GM Energy and PG&E launched the Smart Charge Bundle for buyers and lessees of new Chevrolet, GMC, and Cadillac EVs. The dealer can put a GM Energy home charger on the deal at no extra hardware cost, a value of up to $1,999 if the customer takes the PowerShift, or $899 if the customer takes the PowerUp 2. Install, permits, and any panel upgrade stay on the customer. Enroll in PG&E’s EV Charge Manager and the bill credit is $15 a month, with the companies saying a shift of charging into cheaper hours could save up to another $50 a month. The window runs through February 2027 or until the program is full.

FROM EMPOWER TO THE DEALER SHEET

1. June 9, 2026: Anderson and Sheffer pitch the 250,000-car fleet, V2G software, PG&E’s 2030 targets, and the DTE employee-home test at GM Empower in San Francisco.
2. June 9, 2026: Sheffer’s letter asks utilities for easier enrollment, time-of-use pay, and simpler interconnection, and cites the IEA on V2G’s flexibility.
3. September 24, 2026: GM Energy and PG&E put a no-extra-hardware-cost Level 2 charger and a $15 monthly credit on new GM EV deals in Northern and Central California.

Smart Charge is managed charging. Power goes into the car when the utility wants it to. It is not the V2H Enablement Kit, and it is not a tariff that pays an Equinox to discharge at 6 p.m. That is the split that has followed the Empower stage all summer. Recaps of the 250,000-car line were treated as a plan, because there is still no nationwide button that says export. The thing that scaled to a dealer sheet is the cheaper, one-way version of the same wallbox.

Sheffer Asked Utilities to Make Plug-In Simple

The letter is addressed to America’s utility executives and energy policymakers, not to Equinox owners. Sheffer writes that EVs sit in driveways every night with storage that the grid does not use, while heat, weather, and AI data centers squeeze the system. He points to an International Energy Agency vehicle-to-grid study that flagged V2G for the largest hourly energy flexibility among the options it evaluated, and to the IEA’s Stated Policy case of 250 million EVs on the world’s roads by 2030.

Those quarter-million V2G-capable GM EVs on the road today have the energy capacity to help power 120,000 homes for up to one week. The technology is already parked outside. Let’s turn it on together.

Wade Sheffer, Vice President, GM Energy, June 9, 2026 open letter

The three asks in the letter are enrollment, rates, and the path to participation. GM will help educate customers, he writes, and managed charging and time-of-use plans are a first step. Consumers move when they are paid. Interconnection should not be a custom engineering project for every garage. “A car becomes an asset that offsets its own operating costs,” he wrote, if those pieces exist. If they do not, the asset stays a car, and GM Energy keeps selling kits.

Sodium-Ion Takes the Stationary Grid Job

Empower was not only a car show. Anderson said the bottleneck in this cycle is energy, and that GM is building batteries for large storage systems as well as tapping connected EVs for local grids. The companies said they are working with Peak Energy on sodium-ion cells aimed at stationary storage, with a target to commercialize in 2028. Kurt Kelty runs battery and sustainability work at GM. He told reporters the application should set the battery, and that the sodium-ion design should be 20 percent less expensive to maintain than storage batteries on the market now, in part because it is built to skip active cooling.

That industrial line is the hedge against a slow interconnection slog. AutoGuide’s briefing at the event cited a Goldman Sachs note on data-center demand doubling by 2027, from 31 GW in 2025 to 66 GW, or from 4.1 percent of U.S. power to 8.5 percent. A parking lot of Equinoxes can help at the edge. A utility-scale box does not need 3,300 interconnection desks to move a megawatt.

Second-life packs are already doing plant-level work. Redwood Materials plans to put about 100 repurposed GM packs at a GM plant in Michigan for 1.5 MW of dispatchable power, a project GM said should save more than $3 million on that site’s power bills over the installation’s life. GM also pointed to Redwood’s Sparks, Nevada, microgrid as the earlier proof. Those are electrons GM does not have to route through a suburban permit office.

The 250,000-car fleet is still the largest bidirectional lineup an American automaker can point to, and the PowerShift kit is for sale. The September 24 California bundle is the offer a shopper can take home this fall without waiting for a tariff. Export, the thing Sheffer asked the country’s utilities to turn on, remains a two-partner map and an $8,998 list price away from the driveway.
