Vehicle-to-Grid (V2G) is a bidirectional energy technology that allows an electric vehicle to not only draw power from the electrical grid to charge its battery, but also push stored electricity back into the grid during periods of peak demand. In practice, it means your car or scooter could serve as a mobile energy buffer – charging overnight when grid demand is low and cheap, then sending energy back during peak hours, potentially earning the owner revenue or energy credits.
Some vehicles can also use this stored energy to power appliances at home during outages (Vehicle-to-Home, or V2H). V2G is currently in commercial pilot stages in markets like Japan, the UK, and parts of Europe. In India, it is not yet commercially available – the technology requires compatible vehicles, smart bidirectional chargers, and grid infrastructure that can accept two-way power flows, all of which are still developing.
However, given India’s grid challenges and the scale of EV adoption being targeted for 2030, V2G is a technology with enormous potential, and pilot projects are expected to emerge in the coming years.
