An electric vehicle (EV) owner in Beibei District, Chongqing has become the first in the city to receive payment for feeding electricity back into the grid, marking a major milestone in the rollout of vehicle-to-grid (V2G) technology. The transaction signifies the successful integration of the full V2G process—including equipment installation, metering, settlement, and payment—laying the groundwork for broader vehicle-grid interaction in the future.
V2G technology allows EVs to operate as mobile energy storage units, discharging electricity back to the grid during peak demand periods. This not only helps smooth grid loads but also offers EV owners a new source of income. As part of a demonstration project, State Grid Chongqing Electric Vehicle Service Co., Ltd. recruited six EV owners to participate in a live trial, testing the V2G system's performance across metering, billing, and payment modules.
“Across 35 discharge sessions, the six participants delivered approximately 982 kilowatt-hours (kWh) to the grid, earning a total of 703 yuan—an average of 0.72 yuan per kWh,” said Huang Ziqi, a representative from the marketing department of State Grid Beibei Power Supply Company. Looking ahead, Chongqing EV users will be able to access V2G-enabled charging stations that are part of the city’s pilot program. By simply scanning a code with their mobile phones and following on-screen instructions, drivers can discharge electricity and receive corresponding compensation.
In March, Chongqing was selected as one of China’s first pilot cities for large-scale vehicle-grid integration. A joint policy issued by the Municipal Economic and Information Technology Commission and other departments outlines targets for developing over 100 V2G projects by 2025. The city aims to initially establish a new industrial ecosystem based on vehicle-grid synergy. By 2030, Chongqing plans to implement multiple large-scale V2G demonstration projects, collectively offering up to 100 megawatts of bidirectional flexible regulation capacity to the power grid.
