HDPI(SH:600027) Ren Min Ri Bao·2025-12-02 22:33Core Viewpoint - The Xinjiang Tianshan North Gobi Energy Base is China's first "desert-gobi-wasteland" renewable energy export base, with over 70% of its installed capacity coming from renewable sources, and is nearing full capacity grid-connected power generation [2][6]. Group 1: Project Overview - The Xinjiang Tianshan North Gobi Energy Base covers an area of approximately 1,651 square kilometers and has a total installed capacity of 14.2 million kilowatts [6]. - The project employs a "wind-solar-fire-storage integrated" model, allowing for the coordination of various energy and storage technologies to ensure stable energy supply [6][9]. - Once fully operational, the base is expected to deliver 36 billion kilowatt-hours of green electricity annually through the Hami-Chongqing ±800 kV UHV project [6]. Group 2: Resource Utilization - Hami, where the base is located, has abundant land resources, with 66.57% of its 142,100 square kilometers being Gobi desert, providing excellent conditions for large-scale renewable energy development [3]. - The region experiences nearly 200 days of wind speeds above level 8 annually and has 3,100 to 3,300 hours of sunshine per year, making it one of the sunniest areas in the country [3]. Group 3: Energy Stability and Flexibility - The base features the largest "Gobi" grid-type energy storage system in the country, which is crucial for maintaining the stability of the power system in the face of extreme weather and the intermittent nature of renewable energy [7][8]. - The coal power units associated with the base are designed to operate flexibly, with a minimum output capacity of 20%, allowing them to adjust their output based on the availability of renewable energy [9]. Group 4: Economic Efficiency - The project focuses on optimizing technology to enhance the economic efficiency of power generation and transmission [10]. - The integrated control room for coal and renewable energy projects allows for real-time adjustments to optimize the mix of energy sources based on demand, potentially increasing renewable energy absorption by 3% [12][13]. - The base has implemented a mid-voltage direct current system to reduce transmission losses and improve stability by minimizing conversion processes [13]. Group 5: Water Resource Management - The coal power project has integrated cooling systems to reduce water consumption, achieving a water usage rate of 0.13 cubic meters per megawatt-hour, which is over 60% more efficient than traditional systems [15].
