November 2, 2025: The first phase of an eventual 400MW/1,000MWh BESS in China is set for completion next month, the China Energy Storage Alliance said on October 21.

Construction of the first 107MW/428MWh phase of the project, which the Alliance said will become China’s largest user-side energy storage project, began in Sichuan province on July 30.

The lithium ion BESS is being jointly developed by energy storage systems company Great Power and Zhongfu Aluminum in the Guangyuan economic and technological development zone.

The BESS will reduce electricity costs and boost power reliability for Zhongfu’s manufacturing operations, as well as supporting the regional grid with peak shaving and load balancing.
The second phase of the project will include construction of a 220kV substation, plus wind and solar power facilities and EV charging stations.

Ultimately, the project aims to establish an integrated regional microgrid, which the Alliance said will provide a practical model for China’s power market reform and carbon neutrality goals.

Last August, Great Power said it had supplied the DC-side energy storage systems with LFP batteries for a 200MW/400MWh independent shared BESS in China’s Yunnan province.

Energy data analytics firm Wood Mackenzie said last year that China remains the global leader of the energy storage market, due to its booming solar market, with an average of 42GW/120GWh annual capacity additions expected over the next decade.

Global cumulative capacity will increase sixfold by the end of 2033, passing 1TW/3TWh, according to Wood Mackenzie.
