Yongtai Digital Energy Achieves Milestone with 30 MWh ESS Project in Shandong

On January 27, Chengshu Electric Power Group announced via its official account that the 10MW/20MWh energy storage project for Yibin Gaoxian Sililya Fiber Technology Co., Ltd. had been successfully completed and connected to the grid. The project commenced construction in October 2025, adopting a mature, safe, and reliable prefabricated cabin-style outdoor layout, with LFP batteries serving as the core equipment. The entire energy storage system consists of two independent 5MW/10MWh energy storage units, each integrating two ESS battery cabins and one boost converter unit. The compact design saves space and enhances system efficiency. This large-scale "green power bank" is designed to achieve a first-year discharge capacity of 5.2417 million kWh, with an average annual discharge capacity of approximately 4.8196 million kWh over its 20-year life cycle.

The SMM battery-grade lithium carbonate index stood at 154,434 yuan/mt. Battery-grade lithium carbonate was priced at 145,000-166,000 yuan/mt, with an average of 155,500 yuan/mt. Industrial-grade lithium carbonate was priced at 142,000-162,000 yuan/mt, with an average of 152,000 yuan/mt. The most-traded lithium carbonate futures contract showed a volatile decline. The price fluctuated within the range of 132,400-152,800 yuan/mt. In terms of market transactions, upstream lithium chemical plants showed low willingness to sell spot orders, resulting in sluggish activity; downstream material manufacturers, however, actively inquired at relatively low prices, demonstrating strong purchase willingness, which contributed to relatively active overall market transactions.

Lithium battery giant R&D Technology announced that it will invest RMB 50 million in Fu'an Guolong Nanomaterials.
