新华社︱能源保供迎寒潮“大考” 多能互补共筑温暖防线

Core Viewpoint - The article emphasizes the importance of a robust energy supply system in China to ensure stable heating and industrial production during the winter season, particularly in the face of cold waves and increased energy demand [2][10]. Energy Supply Assurance - The National Energy Administration has proactively arranged for sufficient coal and natural gas supply, optimized electricity dispatch, and enhanced the efficiency of renewable energy utilization to ensure a comprehensive energy supply system [2][10]. - The average daily coal dispatch in China has remained above 12.3 million tons since October, with coal inventory at power plants reaching 227 million tons, sufficient for 35 days of use [6][10]. Infrastructure Development - The construction of key power grid reinforcement projects is accelerating, with 113 new 500 kV and above grid infrastructure projects put into operation this year, enhancing cross-regional transmission capacity [5][10]. - Major hydropower projects, such as the completion of the 500 kV Lingfeng Line and the operation of multiple units at the Gutianxi Hydropower Plant, are contributing to winter electricity supply [3][5]. Technological Advancements - The integration of new technologies like smart sensing and artificial intelligence is improving the efficiency and reliability of the energy supply system, with proactive repair models reducing average repair times by over 30% [7][10]. - The development of renewable energy projects, such as the 200 MW coal and 610 MW renewable energy integrated project in Xinjiang, is set to enhance green energy contributions to the grid [7][8]. Multi-Energy Coordination - The oil and gas sector is enhancing supply quality and ensuring adequate reserves, with significant progress in gas storage and pipeline interconnections to meet peak demand [10][13]. - The energy supply system is evolving towards a model characterized by multi-energy complementarity, intelligent scheduling, and a focus on green and low-carbon solutions [10][14].
