According to CNESA DataLink, China’s cumulative installed capacity of new-type energy storage has reached 144.7 GW by the end of 2025, accounting for more than two-thirds of the country’s total power storage capacity and 51.9% of the global market.
New-type energy storage refers to technologies other than pumped hydro—primarily electrochemical storage, as well as compressed air and flywheel systems—that can provide electricity output. China has ranked first worldwide in newly added capacity for four consecutive years. Resource-rich regions such as Northwest and North China—where wind and solar potential is abundant—have seen particularly rapid growth, with Inner Mongolia and Xinjiang registering compound annual growth rates exceeding 250% between 2020 and 2025.
Globally, cumulative installed power storage capacity has surpassed 450 GW, with the share of pumped hydro storage falling below 50% for the first time. By 2030, China’s cumulative new-type energy storage capacity is projected to reach 370–450 GW, representing a CAGR of 20%–25%.
