Shenzhen achieves for the first time the settlement of electricity fees for new energy vehicles discharging to the grid.

On the 13th, the Shenzhen Power Supply Bureau of the Southern Power Grid successfully completed the trial operation of the charging station discharge and grid electricity fee settlement. Mr. Li, a new energy vehicle owner, received about 15 yuan in profit from a single operation. A month ago, he discharged about 20 kWh to the grid during peak hours. This is the first time in Shenzhen that new energy vehicles have been able to settle electricity fees for discharging to the grid. "From initially understanding the policy information to finally using the charging station to discharge to the grid with my car, now, new energy vehicles not only make my travel comfortable but also bring me economic benefits," Mr. Li said. He is one of the first users in Shenzhen to participate in the V2G vehicle discharging to the grid. He believes that he can better balance the use of his vehicle with economic benefits in the future. In 2025, the Development and Reform Commission of Guangdong Province issued a reply on the issue of electricity prices for new energy vehicles discharging to the grid. It specifies that the electricity price for new energy vehicles discharging to the grid should adopt a peak-valley electricity price method, specifically determined by multiplying 0.453 yuan per kWh by the peak-valley ratio coefficient. In response to the different grid settlement methods for traditional distributed energy, the Shenzhen Power Supply Bureau of the Southern Power Grid established a specialized pricing and settlement model for V2G, differentiating the setting of time-of-use billing formulas. It accurately bills electricity consumption during peak, off-peak, shoulder, and valley periods in key months and hot months, quantifying the value of new energy vehicles participating in grid regulation as distributed energy storage units. It is understood that Shenzhen is one of the first cities in the country to pilot the large-scale application of vehicle-grid interactions. The relevant person in charge of the Shenzhen Power Supply Bureau of the Southern Power Grid introduced that vehicle-grid interactions provide an innovative solution for solving the contradiction between the rapid growth of new energy vehicle ownership and the distribution grid carrying capacity in Shenzhen. "Guiding new energy vehicles to charge during valley hours and discharge during peak hours through price signals helps unleash the potential of new energy vehicles as 'mobile energy storage' and alleviate local power supply pressure."
