“西电东送”开启绿色重塑新篇章

Core Viewpoint - The article discusses the transformation of traditional energy transmission models in China, particularly focusing on the "West-to-East Power Transmission" initiative, emphasizing the need for a green transition while ensuring energy security in the northwest region [1][3]. Group 1: Green Transformation of Energy Transmission - The National Development and Reform Commission and the National Energy Administration have issued guidelines to enhance the optimization of power grid resources, with the "West-to-East Power Transmission" expected to exceed 420 million kilowatts and add inter-provincial power exchange capacity of around 40 million kilowatts [3]. - The northwest region is projected to deliver approximately 400 billion kilowatt-hours of electricity annually by 2025, which is comparable to the total annual electricity consumption of South Korea or Germany [5]. - The proportion of green electricity in the "West-to-East Power Transmission" is expected to increase significantly, with projections indicating it will reach over 55% by 2025 and 67% under baseline scenarios by 2035, potentially reaching 72% under accelerated scenarios [5]. Group 2: Challenges in the Transition - The transition is not without challenges, as highlighted by the example of existing key transmission lines, which face issues such as high coal power ratios and insufficient renewable energy sources [6]. - The planning and positioning of transmission lines significantly impact their overall effectiveness, indicating that without coordinated resources, even well-designed projects may not yield expected benefits [6]. Group 3: Regional Development Strategies - The article emphasizes the need for differentiated development strategies for provinces like Shaanxi and Gansu, with Shaanxi positioned as a "regulation center" and Gansu as an "export base" for renewable energy [8]. - Gansu is expected to achieve a renewable energy proportion exceeding 60% in its power exports by 2030, leveraging its abundant wind and solar resources [8]. Group 4: Market and Policy Coordination - To address the challenges in the "West-to-East Power Transmission" process, experts suggest enhancing policy coordination, technical systems, and market mechanisms [11]. - Establishing a unified national electricity market and balancing mechanisms is crucial to resolve conflicts of interest among provinces, as current market rules vary significantly [12]. - The article advocates for a collaborative approach to optimize resource allocation and achieve the dual carbon goals, emphasizing the importance of government support and market efficiency [12].
