General Motors pitches EVs and batteries as a “virtual utility” to help stabilize America’s power grid

America’s electric grid is being stressed by extreme weather, aging infrastructure, and a new surge in electricity demand tied to the build-out of artificial intelligence data centers. General Motors is responding by arguing that the bottleneck can be addressed partly by the company’s own hardware: EVs, batteries, and charging systems that can be aggregated and used as distributed energy storage.

At a San Francisco event called GM Empower, GM framed itself not only as an automaker but as a participant in grid reliability, describing a model that combines hundreds of thousands of connected vehicles with stationary storage and software, effectively creating what it presented as a “virtual fleet of power plants.” The plan, reported by Fortune, would rely on two main pillars: making vehicles useful to utilities through bidirectional charging and pairing them with grid-scale batteries.

GM said more than 250,000 of its EVs on U.S. roads can already charge bidirectionally, meaning they can take power from the grid and, under the right configurations, send power back. The company also described a path to expand those capabilities without new hardware. In the same reporting, GM said a firmware update is rolling out for customers with GM Energy vehicle-to-home hardware, converting those systems into full vehicle-to-grid assets and turning home backup systems into grid resources when utilities request them.

A key element of GM’s messaging is that vehicle-to-grid participation can be coordinated in a way that does not require every driver to treat their EV like a power station. GM executives wrote to utilities and regulators about aggregating storage capacity, describing EVs sitting in driveways as an opportunity to pool energy storage for the grid. The approach is aimed at utilities and regulators that can manage interconnection, compensation, and reliability requirements while balancing customer needs.

GM also pointed to a specific pilot to test the idea in practice. Fortune reports that GM is piloting the program in Michigan with DTE Energy at 30 employee homes. The company’s longer-term vision, as described in the reporting, includes a plan for 2030 in which more than 52,000 GM EVs would help balance the grid in a projected area where the total vehicle count could reach about 130,000.

The pitch is occurring as Detroit’s automakers look for new revenue opportunities tied to energy infrastructure. The reporting notes that Ford has been moving in a different direction, including a branded Ford Energy effort, and both companies appear to be racing to repurpose underused EV capacity into a more immediate grid-stability need driven by the AI era.

If GM’s plans work, the company would deepen its footprint beyond selling cars and charging equipment, potentially positioning itself closer to an energy-services provider. For utilities, aggregated EV flexibility could represent a new kind of storage resource that complements conventional grid batteries, especially during peak periods when demand and renewable generation can be hardest to balance.

Still, important details are not clear from the event write-up. The reports do not specify the exact tariff or compensation structure for participating customers, the capacity GM expects to be available at peak times, or the timeline for scaling beyond pilots and software updates. It also does not spell out how GM’s “unified charging platform” will interoperate with utility programs and other charging ecosystems, or what constraints regulators may impose.

Going forward, the most closely watched items are whether GM expands vehicle-to-grid deployments with utilities beyond the Michigan pilot, whether customer firmware rollouts and participation requirements scale smoothly, and whether regulators approve frameworks for treating EVs as grid assets in a way that is both reliable and acceptable to drivers. Separately, investors and policymakers will watch whether GM’s energy strategy gains momentum as data-center growth intensifies grid demand.
