Electric vehicles are becoming part of a much larger transformation in the way energy is generated, stored, distributed, and used. For much of the past decade, the public discussion surrounding electrification has focused on vehicle range, charging infrastructure, purchase cost, performance, and the reduction of tailpipe emissions. These considerations remain central to adoption, but they no longer capture the full significance of the technology. As electric vehicles become more capable and more widely deployed, their batteries are beginning to connect transportation with the wider energy system.

At New York Energy Innovation 2026, Aseem Kapur, Chief Revenue Officer of GM Energy, presents this convergence as one of the defining developments shaping both the automotive and electricity sectors. Drawing on more than two decades of experience at Consolidated Edison, where his work includes the design, operation, and modernization of New York’s complex distribution system, Kapur approaches vehicle-to-grid technology from the perspective of both the utility operator and the automobile manufacturer. His view is grounded not only in what electric vehicles can technically accomplish, but also in how that capability can operate within homes, utility networks, and the everyday lives of customers.

That convergence broadens the role of the electric vehicle. A vehicle battery is designed first to support mobility, yet the vehicle remains parked for much of the day. When it is connected through compatible bidirectional equipment and managed through secure software, the stored energy inside the battery can also serve a home during an outage. As utility programs and operating frameworks continue to develop, groups of connected vehicles can contribute additional flexibility to the electricity system.

The significance of vehicle-to-grid readiness therefore extends beyond the ability to move electricity in two directions. It rests on whether the vehicle, the home, the charging equipment, the software, the utility, and the customer can operate as parts of one dependable system. The technology creates the physical possibility, while the customer experience and the wider energy framework determine whether that possibility becomes useful at scale.

The Electric Vehicle As An Energy Platform

GM Energy views the electric vehicle not only as a transportation product, but as an energy asset with capabilities that extend beyond the road. Kapur describes the vehicle as a “highly sophisticated mobile energy platform,” a characterization that reflects the growing importance of storage and flexibility within the modern power system.

The electricity challenge is no longer defined solely by how much power can be generated. It is increasingly shaped by where that power is located, when it is available, and how quickly it can respond to changes in demand. Electricity consumption varies throughout the day and across seasons, while heat waves, industrial growth, building electrification, and other sources of demand place additional pressure on generation and the networks that deliver power to customers.

Traditional power systems are designed largely around centralized generation and the one-way movement of electricity through transmission and distribution networks. The growth of distributed energy resources introduces a more dynamic structure. Solar installations, stationary storage, controllable building systems, and electric vehicles can absorb, retain, and release energy across a wide range of locations.

Within this changing system, the electric vehicle holds a distinctive position. Its battery enters the market primarily to support transportation, but bidirectional technology allows that same asset to provide additional value while it is stationary. The vehicle can move people and goods when it is needed on the road, support the home when the grid is unavailable, and potentially contribute to approved utility programs when it is connected. This expanded role does not diminish the vehicle’s primary purpose. It builds upon it by allowing the battery to remain productive during periods when the vehicle would otherwise be parked.

Consumer Resilience And The Home Energy Experience

The most immediate and tangible value of bidirectional charging is the ability to support a home during an electricity outage. When a compatible vehicle connects to a properly equipped home energy system, the battery can provide stored power to household circuits and essential equipment while grid service is interrupted.

Kapur describes an experience intended to operate with very little intervention from the customer. When the vehicle is plugged in and an outage occurs, the system can transfer the home to vehicle power and notify the customer through the mobile application. The transition is designed to be quiet, automatic, and simple enough that the customer may not immediately notice that grid service has been lost.

This simplicity is central to the value of the system. Consumers are not expected to manage the technical details of energy transfer or understand the operational requirements of the electric grid. They establish their preferences, determine how much battery capacity must remain available for transportation, and allow the system to manage the remaining flexibility within those limits.

The customer therefore remains in control of the asset. Mobility requirements continue to take precedence, while the home energy system creates an additional layer of resilience when the vehicle is available. The value becomes visible not through a complex technical process, but through the continuity of everyday life during an outage.

This is an important distinction. Advanced energy technology becomes meaningful to consumers when it addresses a practical need without introducing unnecessary complexity. A vehicle that can keep a home operating during an interruption creates a direct and understandable benefit, making the broader idea of bidirectional energy far more tangible.

The Wider Value To The Electricity System

The value of one connected vehicle is primarily local and personal. The combined capacity of many vehicles creates a wider opportunity for the grid.

Electric utilities must build and operate their systems to serve periods of maximum demand, even when those periods occur for only a limited number of hours each year. These peaks influence major investments in generation, substations, transformers, cables, and other infrastructure because the system must remain reliable under its most demanding conditions.

Kapur draws on his experience at Con Edison to explain the importance of these brief but consequential periods. During severe heat waves, electricity use can increase rapidly as cooling systems operate across a city or region. The utility must maintain sufficient capacity to serve that demand, even if the highest level is reached only occasionally.

A coordinated group of electric vehicles can introduce another source of flexibility during these conditions. Charging can be reduced or shifted when the system is constrained, allowing demand to move away from the most difficult periods. Under approved operating conditions, connected vehicles can also make stored energy available to support the system.

The contribution from any individual vehicle may be limited, but the combined response from a large and geographically distributed group can become significant. Kapur describes the opportunity as transforming vehicle batteries into “a coordinated dispatchable asset base” capable of supporting grid stability, moderating peak demand, and strengthening resilience where it is most needed.

The practical value of such a resource depends on coordination rather than battery capacity alone. Vehicles are not always connected, customers follow different travel schedules, and available energy varies throughout the day. A large participating fleet allows these differences to be managed across the group, creating a more stable and predictable resource than any single vehicle can provide.

The electricity system does not require every vehicle to be available at the same moment. It requires enough participating vehicles to be connected, sufficiently charged, and responsive under the terms of the program. In that context, the scale of the fleet becomes important because it provides the diversity needed to convert variable individual behavior into a more dependable collective response.

The Importance Of Location And Timing

The value of stored electricity is shaped not only by the amount of energy available, but also by where and when it can be used.

Kapur illustrates this point through the underground distribution network in Manhattan. When an outage affects underground equipment, restoration can require extensive field work and may take many hours. Utility crews may need to identify the fault, install temporary cables, or deploy diesel generators while permanent repairs are completed.

At the same time, thousands of electric vehicles may be parked in garages close to the area experiencing the disruption.

The example highlights the local character of grid resilience. Stored energy positioned close to an area of high demand or system disruption may have greater practical value than the same amount of energy located farther away. A connected vehicle near a constrained part of the distribution network can potentially support that area in ways that a distant resource cannot.

This locational value also varies by region. A dense urban network may place particular importance on localized backup capacity and distribution support. A system with substantial renewable generation may benefit from encouraging vehicles to charge when electricity is abundant. Another region may focus on reducing demand during a steep evening peak.

Vehicle-to-grid capability is therefore not a uniform service with the same value everywhere. Its usefulness reflects the specific conditions of the electricity system, the location of participating vehicles, and the needs of the customers who own them.

From Technical Capability To Operational Readiness

Vehicle-to-home capability and broader vehicle-to-grid participation share the same technological foundation, but they operate within different frameworks.

A compatible vehicle can already provide backup power to a properly equipped home. Wider grid participation requires additional coordination among the automaker, the customer, the utility, and the regulatory system. Approved equipment, interconnection procedures, communication standards, compensation structures, cybersecurity, and customer consent must all be established before a vehicle can operate as a dependable grid resource.

Kapur emphasizes that the underlying technology is already available.

GM’s work with utilities in California and Michigan reflects the transition from technical capability to practical deployment. In California, GM works with PG&E on the integration of bidirectional vehicles into the utility system. In Michigan, GM and DTE Energy test the technology through an active pilot involving GM employees.

These programs provide operational knowledge that cannot be developed through laboratory work alone. Utilities can observe when vehicles are connected, how much capacity is available, how quickly the system responds, and how the technology interacts with actual distribution conditions. Automakers can study the customer experience, software performance, and the relationship between energy participation and transportation needs.

The programs also create information that supports regulatory and commercial development. Customer protection, interconnection, compensation, and the treatment of customer-owned energy resources all require evidence drawn from real-world operation.

Vehicle-to-grid readiness therefore develops across several dimensions at once. The vehicle may be technically capable, but the wider system becomes ready only when all participants can interact reliably and the customer remains confident that the vehicle will continue to serve its primary purpose.

Software As The Connection Between Vehicle, Home, And Grid

The battery and bidirectional charger enable the physical movement of electricity. Software connects the different parts of the system and makes the experience manageable for the customer.

Kapur describes GM Energy’s objective as managing the full energy journey, from battery-cell chemistry to the mobile application in the customer’s hand. The application provides the interface through which the customer can view available energy, manage charging, establish backup preferences, and eventually participate in eligible utility programs.

The customer can determine the amount of driving range that must remain protected and the battery capacity that may be used for home energy or other approved purposes. The system can then manage charging and power transfers within those boundaries, allowing the customer to retain control without supervising every technical decision.

Behind the interface, the software must communicate with the vehicle, charging equipment, home energy system, and utility platform. It must also account for grid conditions, electricity rates, interconnection requirements, and secure data exchange.

The mobile application therefore becomes more than a conventional vehicle feature. It serves as the point of coordination among transportation, household energy, and the wider electricity system.

The quality of this experience is likely to influence the pace of adoption. When the system is clear, responsive, and easy to control, the customer experiences the benefits without confronting the complexity of the infrastructure behind them. When the system operates quietly and reliably, advanced energy technology becomes part of the normal ownership experience rather than a separate technical undertaking.

Scale And The Growth Of A Distributed Resource

Kapur says GM has nearly a quarter-million bidirectional-capable electric vehicles on United States roads and offers models across a wide range of price points and vehicle categories. He also says future GM electric vehicle launches will incorporate this capability.

The growing number of compatible vehicles expands the potential energy resource available across homes and communities. The practical value, however, depends on how many customers participate, how frequently vehicles are connected, how much battery capacity is available, and where those vehicles are located.

Not every vehicle contributes at the same time or in the same way. A customer who drives long distances may reserve more energy for transportation, while another vehicle may remain connected for much of the day. Some vehicles may be positioned in areas where grid support is particularly valuable, while others may serve primarily as home backup resources.

A larger fleet allows this variety to become an advantage. Different schedules, locations, and usage patterns can create a more balanced combined resource, reducing dependence on any one customer or vehicle.

Scale also brings the automotive and energy sectors into a closer commercial relationship. Vehicle manufacturing determines how many capable batteries enter the market. Software determines how those batteries are managed. Utility programs determine how their flexibility can be used. Customer participation ultimately determines how much of the potential becomes available.

Kapur places this work within GM’s broader industrial development. He says the company has reduced its operational emissions footprint by 52 percent since 2018, matches the electricity used across its domestic manufacturing and corporate facilities with renewable energy, and continues to expand its electric vehicle sales.

The broader significance lies in the connection among industrial scale, customer adoption, and energy capability. Bidirectional charging becomes more consequential as it moves from a limited technical feature into a capability distributed across a substantial vehicle population.

Beyond Residential Vehicle Aggregation

Electric vehicles can contribute to a more flexible energy system, but they cannot address every storage requirement.

Some grid needs are local and relatively brief. Others involve large industrial demand, longer operating cycles, or sustained support for the bulk power system. These applications require stationary storage designed specifically for their operating conditions.

Kapur describes this as a matter of matching battery chemistry to its intended purpose.

Vehicle batteries must balance range, weight, power, charging performance, and operation under changing driving conditions. Stationary batteries remain in one location and can be optimized around different priorities, including cycle life, durability, thermal performance, material availability, and long-term cost.

Kapur points to GM’s work with Peak Energy on sodium-ion battery cells for grid-scale stationary storage. This approach allows the company to apply its battery-development capabilities to a form of storage designed around the requirements of the electricity system rather than mobility.

Distributed vehicle batteries and stationary storage therefore serve complementary purposes. Electric vehicles provide mobile, customer-connected capacity that can support homes and localized grid needs. Stationary systems provide dedicated storage at known locations and can be designed for larger or more sustained applications.

Together, these resources reflect the diversity of the energy system itself. Different forms of storage can address different operational requirements, creating a broader and more adaptable foundation for grid resilience and growth.

A More Connected Energy Future

The boundaries between transportation and energy are becoming increasingly fluid.

Electric vehicles remain mobility products, but the batteries they carry also create new possibilities for household resilience and system flexibility. Compatible home energy systems already allow vehicles to support customers during outages, while utility programs are beginning to examine how groups of connected vehicles can contribute to broader grid needs.

The continued development of this capability brings together industries that have traditionally operated through separate systems. Automakers understand the vehicle, battery, and customer relationship. Utilities understand the operation of the electric network and the conditions that create value in particular locations. Regulators establish the rules and protections governing participation, while technology providers connect the physical and digital systems involved.

Customers remain central because the resource belongs to them. Their transportation needs, preferences, and confidence determine whether the battery becomes available for any purpose beyond driving.

Vehicle-to-grid technology does not replace investment in generation, transmission, distribution infrastructure, or stationary storage. It adds another source of flexibility by making fuller use of battery capacity already entering the economy through transportation.

A conventional vehicle provides most of its functional value while it is moving. A bidirectional electric vehicle can continue to provide value while it is parked and connected. It can support the home during an outage, adjust charging in response to electricity-system conditions, and potentially contribute stored energy when the wider network requires additional flexibility.

Kapur describes electrification as something larger than any individual vehicle, product, or manufacturing facility.

The technology is moving from isolated capability toward a more integrated energy model in which vehicles, homes, and the grid operate in closer coordination. As Kapur observes, “The technology is here. The hardware is on the road. The scale is real.”

Electric vehicles continue to move people and goods. As bidirectional capability expands, they also become part of a more connected, resilient, and flexible energy system.
