Chongqing Paves the Way for a New Era of Grid-Integrated Electric Vehicles
Chongqing, China – In a significant step towards a more sustainableand efficient energy future, Chongqing has become the first city in China to conduct a large-scale pilot program for vehicle-to-grid (V2G) technology, effectively turning electric vehicles (EVs) into power banks for the grid.
The pilot program, launched on August 24th, saw the participation of 120 EVs in a two-hour V2G demonstration. These vehicles discharged a combined total of over 1,700 kilowatt-hours (kWh) of electricity back into the grid,enough to power over 420 households for an hour. This initiative aims to alleviate peak load pressure on the power grid by utilizing the stored energy in EVs.
Beyond V2G, the pilot program also included a large-scalepeak-shaving strategy, with 75,600 EVs participating in off-peak charging. This strategic charging approach resulted in a peak load reduction of over 260,000 kilowatts during peak hours. Additionally, 88 charging stations were integrated into a virtual powerplant system, further contributing to peak load reduction by nearly 10,000 kilowatts.
The pilot program is a direct response to the Opinions on Strengthening the Integration and Interaction between New Energy Vehicles and the Power Grid, jointly issued by the National Development and Reform Commission, the National Energy Administration,the Ministry of Industry and Information Technology, and the State Administration for Market Regulation in January 2024. This document outlines a comprehensive strategy for promoting V2G technology and the integration of EVs into the power grid.
The Opinions set ambitious goals for the future of V2G in China. By2025, the country aims to establish a comprehensive technical standard system for grid-integrated EVs, implement a full-fledged peak-valley pricing mechanism for charging, and significantly advance market mechanism development. The plan also calls for intensified pilot programs, aiming to achieve a scenario where 60% of all chargingoccurs during off-peak hours in participating cities by 2025, with private charging stations reaching an 80% off-peak charging rate.
Looking further ahead, the Opinions envision a future where V2G technology is fully integrated into the power grid by 2030. Thisvision includes a fully developed technical standard system, a robust market mechanism, and widespread adoption of smart, orderly charging practices. By 2030, EVs are expected to become a critical component of the electrochemical energy storage system, providing the power grid with a flexible regulation capacity of tens of millions of kilowatts.
This pilot program in Chongqing marks a significant step towards realizing this vision. It showcases the potential of EVs to not only reduce reliance on fossil fuels but also to actively contribute to a more stable and efficient power grid. The program’s success will likely inspire other cities across China to adopt similar initiatives, accelerating the transitiontowards a more sustainable and interconnected energy system.
The success of the Chongqing pilot program also highlights the growing importance of V2G technology globally. As the number of EVs continues to rise, V2G has the potential to transform the way we manage and utilize energy. By enabling EVs to act as distributed energy storageunits, V2G can help to balance the grid, reduce reliance on fossil fuels, and create a more resilient and sustainable energy system for the future.
