June 25, 2025 | Beijing, China — China Energy Engineering Group Co., Ltd. (CEEC), one of the country’s leading state-owned energy conglomerates, has officially opened the bidding for its 2025 centralized procurement of lithium iron phosphate (LFP) energy storage systems. With a total scale of 25GWh, this marks the largest single tender for energy storage systems in China’s history to date.
According to official bid documents and multiple industry reports, the procurement is divided into three distinct packages:
-
Package I: 1-hour duration systems (1C), totaling 3GWh;
-
Package II: 2-hour duration systems (0.5C), totaling 12GWh;
-
Package III: 4-hour duration systems (0.25C), totaling 10GWh.
More than 70 domestic energy storage manufacturers participated in the bidding, which has been highly competitive. Packages II and III drew the most attention due to their large volumes. The lowest recorded bid for Package III reached just ¥0.37/Wh ($0.051/Wh), setting a new record low for centralized procurement pricing in China. Average bids across the packages ranged between ¥0.42 and ¥0.46 per watt-hour.
CEEC stipulated stringent qualification criteria for bidders, including proven performance benchmarks of at least 100MWh for high-rate systems over the past two years. This reflects the state-owned giant’s emphasis on system reliability, delivery capability, and operational experience in utility-scale deployments.
This landmark tender pushes CEEC’s total procurement volume in 2025 to over 31GWh, accounting for more than 27% of all centralized storage procurement by China’s central and state-owned enterprises this year, which collectively stands at 91.5GWh.
Analysts say this move further solidifies CEEC’s role as a key player in China’s national energy storage strategy. As the nation accelerates its renewable energy rollout and grid modernization efforts, this mega-tender is expected to reshape supply chain dynamics, pricing benchmarks, and technical standards in the energy storage sector.
