Core Viewpoint - The article discusses the reasons behind China's stable electricity supply during the summer despite record-high electricity consumption, highlighting the effective management of power generation, grid optimization, and energy storage solutions [4][5][8]. Group 1: Electricity Consumption and Supply - In July, China's electricity consumption exceeded 1 trillion kilowatt-hours for the first time, marking an 8.6% year-on-year increase [2][4]. - The total installed power generation capacity reached 3.67 billion kilowatts, a year-on-year increase of 18.2%, equivalent to the capacity of over 160 Three Gorges power stations [5]. Group 2: Power Generation Sources - New power generation projects have been launched, including the largest thermal power plant in the eastern coastal region and significant wind and hydropower projects in high-altitude areas [5]. - Renewable energy generation increased by 15.6% in the first half of the year, with one-third of the total electricity consumption now coming from green energy sources [5]. Group 3: Grid Optimization - The completion of over 160 key grid projects and the operation of more than 40 ultra-high voltage transmission projects have enhanced the inter-regional electricity supply capacity [7]. - A new electricity trading mechanism has been established, allowing for efficient electricity distribution across different regions, with cross-regional electricity transactions reaching 855.8 billion kilowatt-hours, a 9% increase year-on-year [7]. Group 4: Energy Storage Solutions - The use of energy storage systems has increased significantly, with new storage facilities providing substantial support during peak demand periods [8]. - The growth of new energy storage installations has surged nearly 30 times over the past five years, enabling better management of electricity supply and demand [8]. Group 5: Demand-Side Management - Initiatives to encourage energy conservation among residents have been implemented, resulting in significant reductions in peak load demand [9]. - The introduction of virtual power plants in residential areas allows electric vehicle owners to charge during off-peak hours and discharge during peak hours, alleviating grid pressure [9].
