Lithium Carbonate Import Price Soared in March from a Year Ago

Recently, the official account of Shaanxi Construction No. 7 Construction Group announced that Phase I of the 200 MW/301.75 MWh hybrid frequency regulation ESS power station project in the Yuncheng Economic and Technological Development Zone, Shanxi, which it undertook, was successfully connected to the grid and officially entered the trial operation stage. The project mainly includes the construction of a 50 MW flywheel independent frequency regulation ESS, a 150 MW LFP electrochemical ESS, a 220 kV substation, and supporting facilities, adopting a hybrid model of “flywheel energy storage + LFP electrochemical energy storage.”

Recently, the PV+ESS integration project of Xuzhou Sinoma Cement Co., Ltd., invested in and built by Sinoma Overseas, successfully achieved a breakthrough at a key period and was officially energized and put into operation on March 16, 2026, marking the formal commissioning of this regional integrated demonstration project for “hybrid energy storage + PV.” The project deeply integrated PV power generation and hybrid energy storage technologies to establish a clean energy supply system featuring “self-generation for self-use, flexible regulation, safety, and high efficiency.” The project’s total ESS installations capacity reached 10 MW/20 MWh, with total PV capacity of 11.38 MW, forming a complete green energy chain of “PV power generation + hybrid energy storage,” providing continuous and stable power support for production processes, building a closed-loop smart energy system with deep integration across the power generation side, energy storage side, and power consumption side, and realizing intelligent coordination and optimized operation throughout the entire life cycle of energy production, storage, consumption, and regulation.

Recently, the Shijiazhuang Gaoyi County 300 MW/600 MWh shared ESS power station, a key new-type energy storage project in Hebei province, officially completed the full-capacity delivery of its ESS, marking this regional benchmark energy storage project’s entry into the critical stage before production and operation. The successful delivery of the Gaoyi County 300 MW/600 MWh shared ESS power station represents another landmark implementation of Zhiguang Energy Storage’s core technologies in large-scale shared energy storage projects in north China, further consolidating Zhiguang Energy Storage’s industry-leading position in the field of cascaded high-voltage, large-capacity energy storage.
