统一电力市场建设迈出关键步伐

Core Viewpoint - The establishment of a nationwide unified electricity market system is a crucial task for deepening electricity system reform and building a unified national market, with the recent implementation of a normalized electricity trading mechanism across grid operation areas accelerating this process [1][2]. Group 1: Market Structure and Development - The electricity industry in China has transitioned from a planned electricity system to a market-oriented one, with market transactions expected to exceed 6 trillion kilowatt-hours in 2024, accounting for 63% of total electricity transactions [1]. - The separation of the State Grid and Southern Grid since the 2002 reform has led to a lack of interconnection and a normalized trading mechanism, hindering the optimal allocation of electricity resources nationwide [1][2]. Group 2: Cross-Grid Trading Mechanism - The newly established cross-grid trading mechanism allows for a unified online electricity marketplace, enabling electricity resources to flow freely across the country based on a standardized set of rules [2][3]. - The mechanism facilitates the collection of cross-grid trading demands and ensures precise matching of supply and demand through information exchange between trading centers in Beijing and Guangzhou [3]. Group 3: Green Energy Consumption - The new trading mechanism enhances the convenience of green energy consumption, allowing renewable energy projects to participate as basic trading units, thus promoting the free flow of green electricity between regions [3][4]. - The first cross-regional green electricity transaction was successfully completed in March, demonstrating the practical application of the new trading mechanism [3]. Group 4: Supply and Demand Management - The cross-grid trading mechanism has already shown initial effectiveness, with significant volumes of green electricity traded between regions, particularly during peak demand periods [6]. - The mechanism is expected to improve the utilization of transmission channels and enhance the capacity for renewable energy consumption, thereby providing more flexible supply guarantees [6]. Group 5: Future Development Directions - In 2023, the country plans to implement normalized trading across various timeframes, supporting electricity supply during peak demand periods and exploring long-term green electricity trading agreements [7]. - The ongoing physical interconnection between the State Grid and Southern Grid will further enhance resource optimization capabilities, leading to more frequent and shorter trading cycles [7].
