Core Viewpoint - The establishment of the "Shagohuang" renewable energy base in Hami, Xinjiang, aims to leverage abundant wind and solar resources to enhance energy supply stability and promote clean energy transition in China [1][3]. Group 1: Project Overview - The "Shagohuang" renewable energy base is China's first renewable energy export base located in a desert area, with over 70% of its installed capacity coming from renewable sources [1][3]. - The project covers an area of approximately 1,651 square kilometers and has a total installed capacity of 14.2 million kilowatts [3]. - Upon completion, the project is expected to generate 14.2 billion kilowatt-hours of green electricity annually, saving 4.27 million tons of standard coal and reducing carbon dioxide emissions by 11.72 million tons [3]. Group 2: Resource Utilization - Hami has a vast land area of 142,100 square kilometers, with 94,600 square kilometers of desert, providing ample space for large-scale renewable energy development [2]. - The region experiences nearly 200 days of strong winds (over level 8) and has an annual sunshine duration of 3,100 to 3,300 hours, making it one of the sunniest areas in the country [2]. Group 3: Energy Integration and Stability - The project employs a "wind-solar-fire-storage integrated" model, allowing different energy sources to complement each other and ensure stable energy supply [3][5]. - The base features the largest "Shagohuang" grid-type energy storage system in the country, which enhances the stability of the power system by actively adjusting output in response to fluctuations [4][5]. Group 4: Economic Efficiency - The project focuses on optimizing technology to enhance power generation efficiency and reduce transmission losses, ultimately providing low-cost electricity [8]. - The integrated control room for coal and renewable energy projects allows for real-time optimization of energy dispatch, potentially increasing renewable energy absorption capacity by 3% [9][10]. - The implementation of a medium-voltage direct current system for solar power reduces conversion losses and enhances stability [11]. Group 5: Water Resource Management - The 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 methods [13]. Group 6: Future Implications - The continuous optimization of technology at the base not only supports the "Jiangdian into Yu" initiative but also provides a replicable model for future "Shagohuang" renewable energy projects and the construction of new power systems in China [14].
