Taiyuan's First 100 MW Standalone ESS Power Station Goes Fully Grid-Connected

[Chile's Lithium Carbonate Exports Totaled 29,500 mt in April 2026, While Lithium Sulfate Exports Totaled 12,100 mt] According to Chilean customs export data, Chile's total lithium carbonate exports in April 2026 were 29,500 mt, up 3.40% MoM and up 35.63% YoY. Among them, exports to China were 22,956 mt, up 21.29% MoM and up 47.67% YoY; exports to South Korea were 3,489 mt, down 45.34% MoM but up 32.47% YoY; exports to Japan were 1,160 mt, down 10.74% MoM but up 48.05% YoY. In April 2026, Chile's total lithium sulfate exports were 12,100 mt, all exported to China, down 26.85% MoM but up 33.57% YoY.

Recently, the Sichuan-Chongqing UHV AC reinforcement project received approval from the National Development and Reform Commission (NDRC). With a total investment of 15.46 billion yuan, the project will construct two new 1000 kV substations in northern Sichuan and eastern Chongqing, adding 12 million kVA of transformer capacity, and build 2×490 km of 1000 kV double-circuit lines including the Chuanbei–Yudong–Bayue route. It is reported that this project is an important component of the Sichuan-Chongqing UHV AC backbone grid, capable of supporting the integration of the Xinjiang-to-Sichuan/Chongqing DC receiving-end converter stations and electricity consumption. It is also one of the 12 national planned power flexible mutual support projects, which is conducive to enhancing inter-provincial power mutual support, surplus-deficit complementation, and emergency accident assistance capabilities between Sichuan and Chongqing. The project is of great significance for ensuring safe and reliable power supply in our province and supporting the construction of a unified national electricity market.

On April 30, the groundbreaking ceremony for the Hainan Jiazheng Wanning 200MW/350.42MWh hybrid energy storage independent frequency regulation power station project was held in Xinglong District. With a total installed capacity of 200MW/350.42MWh, the project leverages cutting-edge technologies in ESS integration and control developed by the research team at Tsinghua University, adopting a "battery + supercapacitor" approach with an innovative configuration of a 25MW/60-second supercapacitor system.
