改造升级拓展煤电能力圈

Core Viewpoint - The coal power industry in China is undergoing significant upgrades to enhance efficiency, flexibility, and environmental standards, driven by the need for energy transition and carbon reduction goals [1][2][4]. Group 1: Current State of Coal Power - Over 80% of coal power units have undergone energy-saving modifications, and over 90% have achieved ultra-low emissions [1]. - Nearly 300 million kilowatts of coal power units have implemented flexibility modifications, effectively reducing coal consumption under rated conditions [1]. Group 2: Challenges and Requirements - The energy transition has increased demands on coal power, requiring it to provide stability while supporting the integration of renewable energy sources [2]. - In 2023, the power sector's carbon emissions accounted for 43% of the national total, necessitating further reductions in coal power emissions [2]. Group 3: New Generation Coal Power Upgrade Action - The new upgrade action aims to transform coal power from a "stable output" model to a "versatile" one, focusing on clean carbon reduction, safety, reliability, and efficient regulation [2][4]. - Key performance indicators for the upgrade include power supply coal consumption, low-load coal consumption increase, deep peak load minimum output, load change rate, primary frequency regulation, and start-stop peak load [3]. Group 4: Implementation Strategies - A multi-faceted approach is required for the upgrade, including policy support, financial mechanisms, and technological innovation [3][4]. - The action emphasizes the need for collaboration among industry, academia, and research to tackle key technologies related to flexibility enhancement, carbon reduction, and intelligent operation [3].
