[Two departments: Promote and improve the new energy storage charging and discharging price mechanism] On November 13, the National Development and Reform Commission and the National Energy Administration issued the "15th Five-Year Plan New Energy Storage Implementation Plan." It is proposed to promote and improve the new energy storage charging and discharging price mechanism. Promote new energy storage to participate fairly in various power markets, and reasonably form charge and discharge prices through market transactions. Research and optimize the system operating cost allocation method. Dynamically improve the peak and valley time-of-use electricity price mechanism based on the actual power supply and demand, and guide industrial and commercial users and industrial parks to build new energy storage.
