What changed
China’s National Energy Administration has set a 2030 target of 300 million kilowatts of new energy-storage capacity, with an average storage duration of about three hours. By the end of 2025, 136 million kilowatts of such storage, equal to 351 million kilowatt-hours, was already operating.
The plan marks a shift from building storage at scale to running it through market mechanisms. It prioritises daily balancing across power sources, the grid and users, while expanding storage’s role in absorbing renewable electricity, securing supply and stabilising the power system.
Why it matters
China is treating batteries and other storage technologies as part of the electricity system’s basic machinery, not merely as backup equipment. The practical test will be whether storage can move electricity into the hours when the system needs it, helping renewable generation serve demand more reliably.
That also changes the business question. The plan calls for better dispatch rules, standards, pricing and commercial models so storage can be paid for its capacity and grid services. If those reforms work, developers may have a clearer route to earning revenue from projects that are useful even when they are not constantly generating electricity.
The policy also aims to strengthen domestic control of key technologies and equipment, while making the industry’s supply chain more resilient. But the plan gives no annual deployment schedule, project-level investment figure or technology breakdown, and it does not show how quickly the market reforms will improve revenues. Progress will therefore be measured not only in installed capacity, but in whether storage is dispatched, valued and paid for as a working part of the grid.
