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 multi-energy supply system to ensure stable energy provision during the upcoming cold wave, highlighting the proactive measures taken by various energy sectors to meet increased heating demands and maintain industrial production stability [1][8]. Group 1: Energy Supply Measures - The National Energy Administration has laid out strategies to ensure sufficient supply of coal and natural gas, optimize electricity dispatch, and enhance the efficiency of new energy utilization to create a comprehensive energy supply system [1][8]. - The average daily coal dispatch in China has remained above 12.3 million tons since October, with coal stockpiles at power plants reaching 227 million tons, sufficient for 35 days of use [3]. Group 2: Infrastructure and Technology Enhancements - Significant investments in power grid infrastructure have been made, with 113 new projects of 500 kV and above completed this year, enhancing cross-regional transmission capacity [2]. - The application of new technologies such as AI and digital twins in energy systems has improved operational efficiency and reliability, exemplified by proactive fault detection systems that have reduced repair times by over 30% [4]. Group 3: Renewable Energy Integration - Renewable energy generation has seen substantial growth, with a 15.5% year-on-year increase in total renewable energy output, accounting for approximately 40% of total electricity generation [5]. - The integration of coal and renewable energy projects, such as the 2 million kW coal power and 6.1 million kW renewable energy project in Xinjiang, is set to enhance energy supply capabilities [5]. Group 4: Oil and Gas Supply Security - The National Pipeline Network Group has completed significant upgrades to natural gas infrastructure, ensuring adequate supply for winter heating needs [7]. - Major oil and gas companies are ramping up production and storage capabilities to meet peak demand, with efforts to secure long-term contracts and optimize LNG procurement [7].
