人民日报丨两大电网余缺互济保供应

Core Viewpoint - The article discusses the recent record-high electricity load in China's power grid and the implementation of a new cross-regional electricity trading mechanism to ensure supply stability and optimize resource allocation across different regions [3][19][20]. Group 1: Electricity Load and Supply - From August 4 to 6, the national grid's electricity load reached a historical high of 12.33 billion kilowatts, equivalent to the output of over 50 Three Gorges power stations [3][19]. - In Hefei, the electricity load exceeded last year's peak value more than ten times since July, indicating a high operational state of the grid [3][19]. - The Southern Power Grid has also contributed to maintaining stable electricity supply, especially during peak demand periods [20][21]. Group 2: Cross-Regional Electricity Trading Mechanism - The National Development and Reform Commission and the National Energy Administration issued a plan to break the segmentation of electricity markets between the State Grid and Southern Grid, enabling mutual support across the national power system [20][24]. - A joint electricity trading initiative between Beijing and Guangzhou trading centers facilitated the transfer of over 20 billion kilowatt-hours of electricity from Southern regions to Eastern regions, benefiting approximately 800,000 households [20][21]. - The new trading mechanism is expected to enhance market competition and ensure electricity supply during critical periods [21][24]. Group 3: Challenges and Solutions - Previous electricity trading between the two grids was limited due to a lack of a standardized market mechanism, relying mainly on government agreements and emergency dispatch [23][24]. - The complexity of organizing cross-regional trading requires precise assessments of supply and demand, as well as efficient coordination between trading platforms [23][24]. - The implementation of detailed business process guidelines for cross-regional trading aims to improve participation and reduce transaction costs for market players [23][24].
