[Energy Storage: Hybrid Energy Storage Project In Shanxi Enters Grid-Connection Commissioning Phase]
Recently, the Shanxi Xiangyuan 42.5MW lithium-ion battery and supercapacitor hybrid energy storage project has entered the grid-connection commissioning phase. The project is jointly constructed by Shanxi Zhongsheng Smart Power Co., Ltd. and Shanxi Zhixian New Energy Co., Ltd., with a total investment of 206 million yuan. Among them, the lithium-ion battery installation scale is 32.5MW/130MWh, a standard "four-hour" configuration, while the supercapacitor installation scale is 10MW/0.083MWh, enabling "rapid power braking or acceleration" within tens of seconds. The lithium battery handles large-capacity energy storage, while the supercapacitor achieves millisecond-level fast frequency regulation. The system can serve both peak-valley arbitrage and grid auxiliary frequency regulation, stabilizing the output of new energy power generation.
