Group 1: Electricity Market Transactions - From January to June, the total electricity market transaction volume reached 2.95 trillion kilowatt-hours, representing a year-on-year increase of 4.8% [1]. - Cross-provincial and cross-regional electricity trading accounted for 670.7 billion kilowatt-hours, showing a year-on-year growth of 18.2% [1]. Group 2: Renewable Energy Consumption - Cross-provincial and cross-regional electricity trading allows for better integration of various power sources, effectively ensuring electricity supply and promoting the consumption of surplus renewable energy [1]. - For instance, during periods of high photovoltaic generation in Xinjiang, Guangdong experiences peak electricity demand, showcasing the benefits of inter-regional trading [1]. Group 3: Future Projections - According to the "2024 Annual Report on the Development of China's Electricity Market," the total volume of medium- and long-term cross-provincial and cross-regional trading is projected to reach 1.39 trillion kilowatt-hours in 2024, reflecting a year-on-year increase of 19.8% [1]. - Provincial electricity spot trading is becoming more active, with Hubei being the largest seller, accounting for approximately 17.16% of total transaction volume; while Zhejiang and Sichuan are the largest buyers, representing 34.12% and 23.73% of total purchasing volume, respectively [1].

Core Viewpoint - The article discusses the increasing electricity demand in China due to high temperatures, with a projected peak load increase of over 10 million kilowatts compared to last year, highlighting the need for enhanced power supply measures and innovative solutions in energy management [1][2]. Group 1: Electricity Demand and Supply - The highest electricity load during the summer is expected to increase by over 10 million kilowatts year-on-year, putting pressure on power supply [1][2]. - The current electricity supply relies heavily on thermal power, with coal supply stability being crucial for meeting industrial and residential electricity needs [1][2]. Group 2: Coal Supply and Transportation - The Hebei power plant is required to store 7,000 tons of coal daily to ensure continuous fuel supply, maintaining over 20 days of coal availability as of June 23 [2]. - In the first five months of the year, the national railway transported 845 million tons of coal, including 575 million tons of electricity coal, ensuring high levels of coal storage at power plants [2]. Group 3: Renewable Energy Growth - As of the end of May, the total installed capacity of wind and solar power has surpassed that of thermal power, with solar capacity growing by 56.9% year-on-year [3]. - The Huaneng Kubuqi New Energy Base has generated over 119 million kilowatt-hours of electricity since June, showcasing the increasing role of renewable energy in power supply [2]. Group 4: Infrastructure and Technological Innovations - National grid investment reached 204 billion yuan in the first five months, a 19.8% increase year-on-year, with 140 key projects for summer peak load expected to be completed [3]. - The application of artificial intelligence in power management is being explored to optimize grid resource allocation and improve operational efficiency [4]. Group 5: Market Mechanisms and Cross-Regional Cooperation - The establishment of a unified national electricity market and regular cross-regional green electricity trading is enhancing the optimization of electricity resources across the country [5]. - The recent cross-regional green electricity transaction involved 16.37 million kilowatt-hours, marking a significant breakthrough in inter-regional electricity trading [4][5].
