Core Viewpoint - The commencement of the 1 million kW/6 million kWh energy storage project in Ulanqab City, Inner Mongolia, marks a significant advancement in China's new energy storage industry, being one of the largest power-side electrochemical energy storage projects globally [1][4]. Group 1: Project Overview - The project is a collaboration between China Power Construction Corporation's Water Resources and Hydropower No. 16 Engineering Bureau and Fujian Yongfu Electric Power Design Co., Ltd., covering design, procurement, construction, and operation and maintenance services [1]. - It involves the construction of a 1000MW/6000MWh electrochemical shared energy storage power station, occupying approximately 700 acres, featuring 1200 units of 5.016MWh lithium iron phosphate battery cabins and 4 units of 250MVA dual-split 220kV main transformers [1]. - The project utilizes advanced lithium iron phosphate storage technology, integrating a conversion and boosting system along with an energy management system, enabling participation in grid frequency modulation, peak shaving, electricity market trading, and capacity compensation [1]. Group 2: Impact and Significance - Upon completion, the project will achieve an annual peak shaving capacity of 2.16 billion kWh, equivalent to the carbon sequestration of 120 million square meters of forest, effectively alleviating the pressure of wind and solar energy curtailment in Ulanqab [4]. - It will enhance the flexibility of the Inner Mongolia power grid, supporting the region's goal of exceeding 50% renewable energy installed capacity by 2025, thereby strengthening the safe and stable operation of the North China power grid [4]. - The large-scale application of advanced electrochemical storage technology in this project serves as a significant demonstration of the "Inner Mongolia solution" for constructing a new power system dominated by renewable energy, having profound implications for the technological upgrade and large-scale development of the national energy storage industry [4].
