General Motors looks to expand access to EV-powered home backup

General Motors is continuing to develop its vehicle-to-home energy strategy as it works to broaden access to home energy management systems tied to its electric vehicles. The automaker said it has sold more than 246,000 vehicles in the United States equipped with the hardware necessary to provide backup power to a properly equipped home during an outage. The company also reports it ranked among the top two electric vehicle sellers in the U.S. in 2025.

Through its GM Energy division, the company offers vehicle-to-home (V2H) capability that allows compatible electric vehicles to supply power to a residence when paired with appropriate home energy management equipment. The system is designed to allow an EV’s battery to serve as a backup energy source during grid outages. When integrated with approved hardware and installation, the vehicle can send electricity from its high-voltage battery to support household circuits.

GM Energy is now exploring a leasing option for its home energy management systems and PowerBank stationary battery storage products. Instead of requiring customers to purchase the equipment outright, the proposed structure would allow homeowners to pay a monthly fee, similar to a vehicle lease. General Motors said the goal is to reduce upfront costs and make the system more financially accessible. Specific pricing, lease terms, and launch timing have not yet been announced.

The company says the leasing program is intended to broaden availability beyond current EV owners. According to Wade Sheffer, vice president of GM Energy, the objective is to lower barriers to entry and allow more homeowners to access integrated energy management technology. GM Energy has positioned its platform as a way for customers to use their electric vehicles not only for transportation but also as part of a broader home energy ecosystem.

Vehicle-to-home capability relies on compatible bidirectional charging hardware, home electrical upgrades, and energy management software. When installed properly, the system can automatically detect a grid outage and switch the home to battery power supplied by the vehicle. Depending on battery size, household consumption, and configuration, an EV can provide temporary backup power to critical loads such as lighting, refrigeration, and communication devices.

GM’s portfolio of EVs with V2H-capable technology includes models built on its Ultium-based architecture, such as the Chevrolet Silverado EV. Battery capacities in these vehicles can exceed 200 kWh, depending on configuration, which provides a substantial energy reserve compared to typical home backup batteries. However, actual backup duration varies widely based on energy use and system setup.

The company provided examples of customers using integrated systems that combine rooftop solar panels, stationary battery storage, and a GM electric vehicle. One such example involved a Silverado EV owner who paired solar generation with a home battery and the vehicle to reduce reliance on the grid and manage electricity costs. In this configuration, the home can draw from solar production during the day, store excess energy in a battery, and use the EV battery as an additional reserve when needed.

GM Energy’s PowerBank products function as stationary home batteries that can store electricity from solar panels or the grid. When combined with vehicle-to-home hardware, the system can be programmed to charge during off-peak hours and discharge during peak pricing periods. This time-of-use strategy can reduce overall electricity costs in regions with variable rate structures.

The company also cited examples of customers maintaining power during extreme weather events, including hurricanes along the Gulf Coast and wildfires in the western United States. In these cases, vehicle-to-home capability allowed homeowners to avoid using gasoline-powered portable generators. Electric vehicle-based backup systems operate without combustion engines, eliminating fuel storage concerns and reducing noise compared to conventional generators.

In Texas, General Motors has partnered with Reliant Energy on a program called “Free Charge Nights,” which offers qualifying customers free overnight charging during designated hours. Programs structured around time-of-use pricing can allow EV owners to charge vehicles when electricity demand and rates are lower, then use stored energy to offset peak-hour consumption. The financial impact depends on local utility rate structures and individual consumption patterns.

Utilities in other regions are also testing broader vehicle-to-everything (V2X) programs. Pacific Gas & Electric (PG&E) in California is running a V2X pilot program that allows participating EV owners to send electricity back to their homes, the grid, or other devices. Eligible applicants in PG&E’s program can receive incentives of up to $4,500 for qualifying GM Energy products, subject to program requirements and funding availability.

Vehicle-to-grid (V2G) functionality extends the vehicle-to-home concept by allowing EVs to export electricity directly to the utility grid under specific conditions. GM Energy said it has completed positive internal testing for vehicle-to-grid capability and is working toward certification with local utilities. Certification processes vary by region and involve compliance with grid interconnection standards, safety requirements, and utility regulations.

If approved more broadly, vehicle-to-grid systems could allow EV owners to participate in demand response programs or grid services, potentially earning compensation for supplying electricity during peak demand events. However, these programs depend on regulatory frameworks and utility participation, and availability differs by market.

GM’s expansion into home energy management reflects a broader trend among automakers seeking to integrate electric vehicles into residential energy systems. EV batteries are significantly larger than most home backup batteries, which can make them a substantial energy asset if properly integrated. At the same time, installation requirements can be complex and costly, often involving electrical panel upgrades, bidirectional charging equipment, and professional installation.

By introducing a leasing model, GM Energy appears to be targeting one of the primary barriers to adoption: upfront cost. While the company has not disclosed pricing details, home battery systems and bidirectional charging equipment can cost several thousand dollars, depending on configuration and installation requirements. A monthly payment structure may make the technology more accessible to homeowners who prefer predictable recurring expenses rather than large initial investments.

The company has not announced whether the leasing program will include maintenance, warranty coverage, or performance guarantees, which are common considerations in residential solar and battery leasing agreements. Additional details are expected closer to launch.

General Motors’ emphasis on energy management aligns with its broader electrification strategy. Beyond vehicle sales, the company has been building out charging infrastructure partnerships, energy services, and software platforms intended to support EV adoption. Integrating transportation and home energy systems represents an effort to extract additional utility from vehicle batteries.

The long-term viability of vehicle-to-home and vehicle-to-grid systems will depend on regulatory approval, customer education, installation capacity, and evolving utility rate structures. While early adopters have demonstrated functional use cases during outages and peak pricing periods, widespread adoption will likely require streamlined installation processes and clear economic benefits.

For now, GM Energy’s announcement signals continued investment in bidirectional charging and home integration. With hundreds of thousands of compatible vehicles already on the road, the company is positioning those vehicles as potential energy assets rather than solely transportation devices. Further details on the proposed leasing structure and rollout timeline are expected in the coming months.
