Down 35% Year-on-Year! CNESA Analysis of Installed Capacity of the New Grid&Source-Side Energy Storage Projects in October

Source: CNESA


After a small installation peak in September, China's new energy storage market saw a temporary decline in October 2025. According to incomplete statistics from the CNESA Datalink Global Energy Storage Database, both the month-on-month and year-on-year growth of newly commissioned capacity declined in October, mainly due to project cycle factors. Meanwhile, profound structural changes are taking place in the market:

● Short-term decline while long-term growth:

Although October's installed capacity declined, the cumulative capacity in the first ten months of 2025 still maintained a robust 36% growth, and 7-9 GW of projects are expected to come online before year-end, suggesting a record-breaking annual installation.

● Independent storage takes the lead:

In October, independent energy storage projects accounted for more than three-quarters of total installations, becoming the absolute main force.

● Third-party enterprises surpass state-owned giants:

A landmark shift occurred - “third-party enterprises”, represented by equipment manufacturers, accounted for over half of the newly installed capacity for the first time, surpassing traditional large energy groups and highlighting a clear trend toward diversified investment.

● Diverse technologies and accelerated non-lithium deployment:

In addition to mainstream lithium-ion systems, technologies such as compressed air, flow batteries, and flywheels are being accelerated in planning and construction, injecting new momentum into the industry's long-term development.

 

Overall Analysis of New Energy Storage Projects in October

 

According to incomplete statistics from the CNESA Datalink Global Energy Storage Database, in October 2025, China added 1.70 GW / 3.52 GWh of newly commissioned new energy storage capacity - down 35% and 49% YoY, and 51% and 66% MoM, respectively. Although the first month of Q4 saw a decrease, total new capacity from January to October reached 35.8 GW, up 36% YoY. Following the September commissioning surge, the October decline mainly reflected the influence of construction cycles.

As of the end of October, about 7-9 GW of new energy storage projects were under commissioning or scheduled for grid connection by year-end. If these projects proceed as planned, China's new commissioned capacity in 2025 could reach 42-45 GW. This estimate is based solely on currently known under-construction/commissioned project data and does not represent a final forecast.
