中能观察丨国网、南网联手，电力全国“大循环”时代来临

Core Viewpoint - The article discusses the significant breakthrough in China's electricity market with the approval of the "Cross-Grid Operating Area Normalized Electricity Trading Mechanism Plan," which allows for the seamless flow of electricity resources across the national grid, marking a step towards a unified national electricity market [1][3]. Group 1: Market Structure and Historical Context - Historically, China's electricity market has been divided between the State Grid and the Southern Grid, with the State Grid covering 26 provinces and accounting for over 88% of the land area, while the Southern Grid operates in five provinces [3]. - This regional division has led to market isolation, preventing efficient electricity transfer between regions, especially during peak demand or surplus generation periods [3][4]. Group 2: Mechanism Implementation and Transactions - The first transaction under the new mechanism involved 2 million kilowatts of electricity flowing from the Southern Grid to the Eastern region, showcasing the mechanism's role in optimizing national electricity resource allocation [1]. - In March, a successful cross-regional green electricity transaction was conducted, marking a significant milestone in the establishment of a normalized trading mechanism [4]. - In June, over 34 million kilowatt-hours of renewable energy were traded across multiple channels, demonstrating the mechanism's ability to enhance market competition and resource efficiency [5]. Group 3: Future Goals and Framework - The plan outlines a phased approach to building a unified electricity market, focusing on foundational improvements, expanding participation, and ultimately achieving rule unification and comprehensive integration [6][7]. - The "Take the Smaller Principle" is a key innovation in ensuring safety and efficiency in transactions, allowing for better coordination between the two grid operators [8]. Group 4: Economic and Environmental Impact - The implementation of this mechanism is expected to significantly enhance market vitality and expand market space, allowing for efficient resource flow and optimization across the country [10]. - It aims to improve the consumption of clean energy by creating stable channels for renewable resources from regions like Southwest China to major consumption areas [10][11]. - The establishment of long-term green electricity purchase agreements is anticipated to stabilize market expectations and drive efficient resource conversion into economic advantages [11][12].
