After several months of installation, commissioning, and grid connection test, the Foshan Hengyi Power plant 20MW/10MWh frequency regulation project has passed the trial operation stage and began official operations on July 21, 2020. The project’s energy storage system has been provided by Tianjin Lishen Battery Co.
Project investment was provided by Guangdong Guangte Electric and system integration delivered by Guangdong Power Research Institute Energy Technology Co., LTD. The project is a large-scale energy storage system bundled with coal generation to provide frequency regulation services, which can significantly improve the flexibility of power grid dispatch, enhance the reliability and safety of power grid operations, and reduce wear to thermal power units. Successful operation of the project can not only greatly improve the AGC regulating performance of the coal generator, providing high quality and efficient frequency regulation service for the grid, but also generate additional frequency regulation compensation income for Hengyi power plant.
