China's energy storage fleet reaches 167 GW with improving utilization

· Energy · China

China's National Energy Administration reported that the country's energy storage installed capacity has grown to 167 GW, a 63% year-on-year increase, alongside longer storage durations and improving utilization rates. The figures underline how quickly China is scaling storage to support its large and growing renewable build-out and to balance an increasingly variable power mix. Longer duration and better utilization suggest storage is moving from a token addition toward a more substantive grid asset. For the global industry, China's pace sets the benchmark for storage deployment costs and manufacturing scale, and signals that storage is becoming a core part of grid planning rather than a marginal adjunct.

Why it matters：China's storage scale-up sets the global cost and deployment benchmark, shaping how fast other markets can integrate variable renewables and who leads storage manufacturing.

Key points

  • Installed storage capacity reached 167 GW.
  • Capacity grew 63% year on year.
  • Storage durations lengthened and utilization improved, per the NEA.
