BEIJING, October 14, 2026
China Energy Storage Alliance (CNESA) has released its latest monthly market assessment for China’s new energy storage sector, showing total newly-commissioned capacity hit 35.30 GW / 102.31 GWh across the first nine months of 2026, broadly matching full-year prior-year performance. After a market correction in H1 2026, the third quarter delivered a strong rebound, driven primarily by stand-alone grid-side energy storage and large-scale long-duration storage assets entering commercial operation.
September marked a turning-point month: newly commissioned new energy storage reached 4.33 GW / 14.08 GWh, rising 42 % year-on-year on power capacity and 69 % on energy capacity, alongside 8 % and 14 % sequential month-over-month growth for power and energy respectively. Q3 total installations surpassed 10 GW for the first time on a quarterly basis, landing at 13.4 GW / 43.0 GWh. While power capacity for the January-September period dipped 3 % year-on-year, energy capacity advanced 6 % versus 2025, signalling larger-duration systems gaining market share.
“Stand-alone energy storage has become the core engine for China’s storage market recovery, as provincial power market reforms open viable revenue pathways for grid-connected storage assets,” said a senior analyst at CNESA. “We are observing an inflection point: long-duration non-lithium technologies are moving beyond demonstration projects toward real-world deployment, even as lithium-iron-phosphate batteries remain the workhorse of the industry. Market expansion will continue to hinge on the roll-out of local electricity market rules and capacity compensation frameworks.”

Note: Year-on-year comparison contrasts figures with the same period of the previous year; month-on-month comparison contrasts figures with the immediately preceding statistical period.
Grid-side stand-alone storage accounted for 85.3 % of September’s newly added power capacity at 3.70 GW /12.29 GWh, with power-capacity growth of 112 % year-on-year. Market reforms across multiple provinces are enabling multi-market participation for stand-alone storage assets. Southern China allows stand-alone storage to take part in both frequency-regulation and spot electricity markets; Zhejiang has implemented a breakthrough mechanism allowing daily switching between energy and frequency-regulation market participation, progressively closing the market-oriented profitability loop for stand-alone storage.
Power-side new-energy paired storage saw slower growth, while customer-side deployments continued a downward trend, with industrial-and-commercial storage making up 95.7 % of customer-side additions.

Note: Others include distribution network side, transformer districts, demonstration & research projects, thermal power coupled storage, EV charging stations, rail transit, port shore power, municipal authorities / critical facilities, data centers, etc.
Regional deployment has grown more balanced. North China led September additions with 1.46 GW power capacity, representing 34 % of national volume, followed by East China at 28 %. Guangdong ranked No. 1 for newly-added power capacity (0.83 GW), and Jiangsu topped national energy-capacity rankings (2.86 GWh), boosted by commissioning of the Jintan Salt Cavern Compressed-Air Energy Storage Phase II project. Analysts note that despite strong local demand, Jiangsu still awaits formal launch of its provincial electricity spot market and finalised capacity-compensation provisions for energy storage, creating uncertainty for future project returns.

At provincial level, significant gaps exist in project scale among provinces.

Technically, lithium-iron-phosphate batteries still represented 73.08 % of September’s commissioned power capacity. Non-lithium long-duration energy storage captured 23.6 % of monthly power additions, with landmark assets coming online including large-scale compressed-air energy storage facilities, vanadium-redox and iron-chromium flow-battery parks, and multi-technology hybrid demonstration sites. The data confirms a complementary multi-technology landscape is emerging, without near-term full replacement of lithium-based systems.

Key take-aways from CNESA analysis
1. Q3 reversed H1 market softness; stand-alone storage business-model maturity is the primary growth driver, subject to provincial electricity-market rule implementation timelines.
2. Long-duration storage is transitioning from demonstration to early commercial deployment; LFP remains the mainstream baseline technology, with complementary multi-technology mix taking hold.
3. Regional policy divergence creates market variance: high-demand provinces such as Jiangsu depend on completed market-mechanism roll-out to unlock full project revenue potential.
