Expected ROI of standalone energy storage project in China 2025

What is the future of energy storage in China?

The new energy storage market in China has great development potential in the future. The cumulative installed capacity of new energy storage in China is expected to exceed 100 gigawatts (GW) by 2025, according to the Energy Storage Industry Research White Paper 2025 released by the Institute of Engineering Thermophysics on 10 April.

How has China shaped its energy investment strategy?

China’s evolving macroeconomic priorities have long shaped its approach to energy investment. While China met its 5% GDP growth target in 2024, the economy faced mounting pressures from weak domestic consumption, deflationary risks and a deepening real estate crisis.

How long does energy storage last in 2024?

Highlights from the 2025 Energy Storage Report According to the NEA, 2024 saw the addition of 42.37 GW / 101 GWh in new NES capacity. The average storage duration rose to 2.3 hours, reflecting ongoing improvements in system design and grid integration.

How big is China's energy storage capacity?

The most notable finding: by the end of 2024, China had reached 73.76 GW / 168 GWh in cumulative new energy storage capacity—an increase of more than 130% year-on-year. This figure accounts for over 40% of the global total, consolidating China's leading position in the international NES market.

What energy storage technologies are available in China?

Currently, there are dozens of new energy storage technology routes in China, including advanced compressed air energy storage, flywheel energy storage, lithium iron phosphate batteries, vanadium redox flow batteries, and sodium-ion batteries, each suitable for different scenarios based on their characteristics.

Does Cnesa have a role in China's new energy storage capacity?

CNESA’s involvement reflects the report’s collaborative yet government-led nature, ensuring data integrity and broad sectoral representation. The most notable finding: by the end of 2024, China had reached 73.76 GW / 168 GWh in cumulative new energy storage capacity—an increase of more than 130% year-on-year.
