Core Insights - The recent extreme heat in China has posed significant challenges to the power system, with the maximum national power load reaching a historical high of 1.465 billion kilowatts on July 4, an increase of approximately 200 million kilowatts compared to the end of June [1] Group 1: Energy Structure Transformation Achievements - The stability of thermal power has been reinforced, with a rapid transition towards cleaner energy. Advanced thermal power technologies have solidified the supply foundation, exemplified by the energy-saving and emission-reduction project at the Beilun Power Plant, which significantly outperforms industry standards in coal consumption and pollutant emissions [1] - The scale and resilience of renewable energy have achieved dual breakthroughs, with cumulative installed capacity of wind and solar power exceeding 1.65 billion kilowatts by May 2025, surpassing that of thermal power. Notably, wind power generation in Hainan surged by 456% year-on-year, while solar power generation in Fujian, Sichuan, and Hunan saw increases of 83%, 51%, and 49% respectively [2] - The role of new energy storage as a "regulator" has become prominent, with a maximum discharge power of 7.14 million kilowatts achieved during peak electricity demand on July 6, showcasing the critical function of storage in stabilizing the power supply and accommodating renewable energy fluctuations [3] Group 2: Infrastructure and Resource Optimization - The national grid's ultra-high voltage backbone network has enhanced cross-regional and cross-provincial transmission capacity to over 200 million kilowatts, providing robust support for stable power supply during the summer heat. Currently, 39 ultra-high voltage projects have been completed, with more major projects underway [3] - The recent heatwave has validated the phased achievements of China's energy transition and outlined the future evolution path of the energy system, emphasizing the shift from deep cleaning of thermal power to large-scale renewable energy, market-oriented application of storage, and nationwide coverage of ultra-high voltage networks [4]
