崔东树：电动车储能推动分时电价调整 重构新型电力系统机制

Core Insights - The development of China's new energy vehicles (NEVs) is significantly enhancing the energy ecosystem, with a current ownership of 43.97 million electric vehicles and a battery storage potential of 2000 GWh, contributing to the stability of the power grid [1][5] - The transition to dynamic pricing for time-of-use electricity is driven by the increasing value of energy storage from electric vehicles, which is expected to facilitate the construction of a new power system and support carbon neutrality goals [1][2] Time-of-Use Pricing Policy Adjustment - The National Development and Reform Commission and the Energy Administration will implement a market-based dynamic pricing model for commercial charging stations starting March 2026, while optimizing residential time-of-use pricing [2] - This shift aims to provide price support for the energy storage value of electric vehicles, moving from a fixed pricing model to a more responsive and market-oriented pricing mechanism [2] Rapid Growth of Electric Vehicle Ownership - As of 2025, the total number of NEVs in China is projected to reach 43.97 million, accounting for 12.01% of all vehicles, with pure electric vehicles making up 68.74% of this total [3] - The annual growth rate of new registrations for NEVs is expected to be 14.93%, indicating a robust market expansion [3] Energy Storage Effects of Electric Vehicles - The large-scale deployment of electric vehicles is transforming them into a significant flexible resource for the power grid, capable of participating in load regulation and energy storage [4][6] - The potential for electric vehicles to provide grid support during peak times and absorb excess energy during off-peak times is becoming increasingly evident, enhancing the overall efficiency of the power system [5][6] Charging Infrastructure Development - The number of public charging stations is expected to reach 4.72 million by December 2025, with significant year-on-year growth, which is crucial for the practical implementation of time-of-use pricing [7][8] - The widespread installation of charging infrastructure is enhancing the ability to manage load and respond to market signals, facilitating the transition to a more dynamic pricing model [8]
