Core Viewpoint - The article discusses the optimization of the electricity pricing mechanism for grid-side energy storage during the peak summer period in Zhejiang Province, aiming to ensure power supply security and enhance the role of energy storage systems [2][3]. Pricing Mechanism - A temporary pricing mechanism for grid-side energy storage projects will be implemented from July 1 to September 15, 2025. Charging prices will follow the general commercial electricity user price based on voltage levels, with charging during non-peak hours priced at off-peak rates [3]. - The discharge price for grid-side energy storage projects will continue to follow the coal power benchmark price, with the cost difference borne by all commercial users [3]. Charging Price Structure - The charging price structure for grid-side energy storage projects specifies that the electricity corresponding to the grid-connected charging volume will not bear transmission and distribution fees or government funds. However, the remaining charging volume will incur these costs [3][4]. Operational Management - The provincial power company is tasked with scientifically and economically scheduling the operation of grid-side energy storage projects to maximize their peak-shaving capabilities. They are required to report the effectiveness of the temporary pricing mechanism [4]. - Once grid-side energy storage projects participate in the electricity spot market, the charging and discharging prices will follow the spot market rules, discontinuing the temporary pricing mechanism [4].
