China Electric Equipment Group awards 7.2 GWh of storage cells in latest tender

China Electric Equipment Group has published the results of its 2025 centralized procurement for energy storage cells, with almost the entire 7,248 MWh tender awarded to 314 Ah products. The tender was divided into 10 packages, the tender covered cell capacities of 50 Ah, 100 Ah, 280 Ah, and 314 Ah.

The scale is notable not only for its size, but because smaller-format packages of 50 Ah (total 16 MWh) and 100 Ah (total 32 MWh) attracted no bids. These cell types often serve behind-the-meter or smaller distributed and grid applications.

In the 314 Ah category, serving large energy storage systems, Cornex secured the largest allocation with 2,920 MWh, followed by Trina Storage with 2,180 MWh, Hithium with 1,400 MWh, and Gotion with 700 MWh. The volumes for 314 Ah cells alone at 7.2 GWh represent a record high for a single centralized procurement in China.

Also: Cornex CEO Dai Deming spoke with pv magazine Managing Director Eckhart Gouras about the battery industry, and Cornex said in 2024 it was able to use its 314 Ah LFP cell to offer its system below $100/kWh in China.

Trina Storage made an official announcement about being a tender winner, one of the few official confirmations from suppliers so far for a procuement that was settled on August 11.

Additional details on pricing, delivery timelines, and other cell formats have not yet been disclosed. More updates are expected as further information becomes available.

China Electric Equipment Group runs a centralized procurement process to pool demand from multiple projects under its portfolio, enabling larger-scale purchases and the potential for lower per-unit costs through the combined bargaining power.
