Core Viewpoint - The article emphasizes the importance of inter-provincial electricity markets in addressing the challenges posed by the uneven distribution of energy resources in China and ensuring efficient power supply during peak demand periods [2][3]. Group 1: Importance of Inter-Provincial Markets - China's energy resources are unevenly distributed, with 90% of coal, 85% of solar, 80% of wind, and hydropower concentrated in the northern and southwestern regions, while 70% of energy demand is in the eastern developed areas [3]. - The increasing volatility of renewable energy and peak load demand exacerbates supply and demand challenges, necessitating inter-provincial market transactions to balance supply and demand effectively [3]. Group 2: Cross-Regional Electricity Transactions - In the summer, the State Grid's operating area achieved 165 million kilowatts of cross-regional electricity transactions, primarily sourced from large coal, wind, solar, and hydropower bases in northern and southwestern regions [4]. - This cross-regional electricity effectively supports the electricity demand in the eastern and central regions, particularly during peak load periods [4]. Group 3: Enhancements in Trading Mechanisms - The Beijing Electric Power Trading Center has implemented a "continuous operation on working days" mechanism to enhance resource allocation efficiency, resulting in a 35.7% increase in transaction volume and a 5% increase in electricity volume year-on-year [5]. - Innovations include optimizing trading processes, establishing a priority mechanism for inter-provincial transactions, and conducting centralized bidding for multiple transmission channels [5]. Group 4: Market Structure and Coordination - The inter-provincial market has established a market model that combines long-term, spot, and emergency dispatching, with long-term transactions accounting for 94.84% of the total electricity volume [6]. - This structure ensures stable supply and demand while providing a safety net through emergency measures when necessary [6]. Group 5: Future Plans for Market Development - Future plans for the Beijing Electric Power Trading Center include expanding trading scope, extending trading periods, and enhancing the proportion of centralized trading across multiple channels [8]. - The center aims to innovate trading varieties and mechanisms to improve supply capacity and facilitate renewable energy consumption [8].
