央企担当铸就温暖防线——能源保供背后的故事

Core Viewpoint - The article emphasizes the critical role of energy supply in ensuring national economic stability and the commitment of state-owned energy enterprises to maintain stable coal and electricity supplies amid complex challenges in 2024, including extreme weather conditions [1][11]. Group 1: Energy Supply Challenges - The energy supply situation in 2024 is complicated, with significant pressure and uncertainty due to frequent extreme weather events affecting electricity supply safety [1]. - The National Energy Group has maintained a high coal production level of 50 million tons for 42 consecutive months, despite challenges such as mine shutdowns and adverse weather [3]. Group 2: Coal Production and Efficiency - The National Energy Group's coal production efforts are crucial for winter power supply, with significant contributions from coal mines like the Shen Dong Bu Lian Ta mine, which can support coastal power plants for extended periods [2]. - The average daily coal output at the Dong Open-pit Mine reached over 70,000 tons during peak winter supply periods, with a single-day maximum exceeding 90,000 tons [3]. Group 3: Transportation and Logistics - The Qinhuangdao Port serves as a vital hub for energy supply, with teams working in extreme cold to ensure coal transportation efficiency, including measures to prevent coal from freezing in transit [5][6]. - The introduction of an upgraded intelligent scheduling system has reduced response times for transportation adjustments during extreme weather to 15 minutes [5]. Group 4: Technological Innovations - The State Grid Corporation has implemented advanced technologies such as drones and AI to enhance power supply reliability and efficiency, particularly in monitoring and maintaining power lines in harsh conditions [7][10]. - The use of a digital twin factory model and IoT technology by China Coal North Machinery Company has improved supply chain management and production efficiency [8]. Group 5: Clean Energy Initiatives - The Southern Power Grid has significantly increased its clean energy capacity, with a 22% year-on-year increase in new energy generation capacity and a 36% increase in new energy output [10]. - The National Energy Group is also focusing on clean energy development, with efforts to ensure stable wind power generation in extreme weather conditions [11].
