Core Viewpoint - The article highlights the increasing electricity demand across various regions in China as summer approaches, prompting power companies to implement multiple strategies to ensure stable electricity supply during peak periods [2][5][10]. Group 1: Electricity Demand and Historical Data - The National Climate Center predicts that by 2025, most regions in China will experience higher temperatures than usual, leading to sustained high electricity demand [3]. - On July 4, the national electricity load reached a record high of 1.465 billion kilowatts, an increase of 0.14 billion kilowatts compared to last year's peak [3]. - Jiangsu's electricity load hit a historical high of 14,996 megawatts on July 3, while Hubei's load reached 5,456.8 megawatts on July 4, marking a 1.02% increase from the previous year's peak [4]. Group 2: Infrastructure Development and Upgrades - Power companies are accelerating key project constructions to enhance grid stability and capacity, with Sichuan completing 13 major projects to bolster its electricity supply [5]. - The Sichuan Panxi 500 kV grid optimization project, which enhances transmission capacity by 2.5 million kilowatts, is set to be operational soon [5]. - In Zhejiang, the completion of nine ultra-high voltage projects has significantly improved the grid's supply capacity, with expectations of peak loads increasing by approximately 1 million kilowatts year-on-year [6]. Group 3: Operational Management and Emergency Preparedness - Power companies are enhancing operational management of key transmission channels and substations, implementing specialized inspections to ensure equipment safety [7]. - Fujian's power company has initiated 425 disaster prevention projects to improve grid resilience against extreme weather [11]. - The use of smart technologies is being prioritized to improve grid regulation capabilities, with Fujian developing an AI-based infrared image screening module to enhance inspection efficiency [8]. Group 4: User Service Enhancements - Power companies are taking measures to improve user service levels during peak demand, including optimizing maintenance operations to minimize outages [10]. - In Zhejiang, over 1,300 micro-grid service points have been established to provide tailored services to businesses, promoting energy efficiency through time-of-use pricing [10]. - Fujian's implementation of AI technology has significantly reduced the workload for manual inspections, enhancing operational efficiency [10].
