en.Wedoany.com Reported - The 300MW/1200MWh grid-side energy storage project, supporting the Green Power Park of the Ningdong Modern Coal Chemical Industry, has completed the full-process commissioning and grid-connection acceptance by the State Grid and has officially been put into operation. This marks the Green Power Park's entry into a new phase of coordinated solar-storage development.
This project serves as the supporting power assurance facility for the first phase of the 1.64 GW composite photovoltaic project at the Green Power Park of the Ningdong Modern Coal Chemical Industry—a distinctive and advantageous industry in the Ningxia Autonomous Region. Construction began on December 22, 2025, with a total investment of 688 million yuan, making it the largest grid-side energy storage project under construction in Ningxia during the same period. The project utilizes a fully outdoor, prefabricated cabin-type lithium iron phosphate energy storage system, integrating advanced technology from CATL. It is configured with 48 sets of electrochemical lithium-ion energy storage systems, equipped with intelligent temperature control and a multi-level fire protection linkage system, featuring millisecond-level response and deep peak-shaving capabilities. Upon completion, it can absorb approximately 300 million kWh of curtailed photovoltaic electricity annually, increase photovoltaic consumption capacity by over 10%, and boost electricity sales revenue by about 90 million yuan.
The first, second, and third phases of the 1.64 GW composite photovoltaic project at the Green Power Park of the Ningdong Modern Coal Chemical Industry were all completed and put into operation in 2025. In recent years, leveraging its abundant wind and solar resources, the Ningdong base has simultaneously deployed new business formats such as green hydrogen, energy storage, and smart grids, driving the industrial chain's transformation from "supply-demand connection" to "data connection," and supporting the base's high-end, intelligent, and green development.
