A bidirectional charging and discharging (V2G) settlement has been implemented in Shenzhen. Last year, the Guangdong Provincial Development and Reform Commission issued rules for the price of discharging new energy vehicles into the power grid with a peak, normal, and off-peak pricing system, with the discharge price calculated by multiplying 0.453 yuan per kWh by a specified coefficient. From this, the Southern Power Grid Shenzhen Power Supply Bureau has developed a dedicated electricity pricing system and settlement model for V2G, and has differentiated its time-of-use billing formula. This quantifies the value of using new energy vehicles as “distributed energy storage units” to adjust the power grid by charging for peak, normal, and off-peak electricity usage on hot days in key months and other months.

According to the Southern Power Grid Shenzhen Power Supply Bureau, V2G provides an innovative solution to resolve the contradiction between the rapidly increasing number of new energy vehicles and the load capacity of the power grid. By using price incentives to encourage charging during off-peak hours and discharging during peak hours, the potential of new energy vehicles as ‘mobile energy storage can be unlashed, and ease local pressure on the power supply.
