Core Insights - The article highlights the significant role of ultra-high voltage (UHV) transmission in ensuring power supply and optimizing energy structure in Henan province amid rising electricity demand due to high temperatures [2][3][4]. Group 1: Power Supply and Demand - Henan province experienced record electricity loads from July 4 to August 4, with a peak of 91.33 million kilowatts, equivalent to the additional load of a city like Luoyang compared to the previous year [2]. - The State Grid Henan Electric Power Company has enhanced power supply through multiple UHV channels, facilitating the import of clean energy from regions like Tianshan and Qinghai [2][3]. Group 2: UHV Infrastructure and Impact - The Lingbao back-to-back converter station, operational for 20 years, has transmitted 129.8 billion kilowatt-hours, significantly reducing coal consumption and CO2 emissions in Henan [3][4]. - The UHV projects initiated in Henan, including the 1000 kV Jin Dongnan-Nanyang-Jingmen and the ±800 kV Hami-Nanyang projects, have strengthened the province's power grid and increased the capacity for external electricity imports to over 20 million kilowatts [4][5]. Group 3: Renewable Energy Development - In the first half of the year, Henan's industrial thermal power generation decreased by 6.5%, while renewable energy generation increased by 20.3%, accounting for 23% of total power generation [5]. - The province has seen a surge in distributed photovoltaic (PV) installations, with total renewable energy capacity reaching 79.1 million kilowatts, surpassing thermal power for the first time [7]. Group 4: Technological Innovations and Electric Vehicle Infrastructure - The State Grid Henan Electric Power Company has implemented an "instant plug and charge" feature for electric vehicle charging, enhancing user convenience [8][9]. - The company has established a comprehensive charging network with 6,991 public charging stations and 52,610 charging piles, addressing the growing demand for electric vehicle charging [8][9]. Group 5: Environmental Impact and Energy Transition - The shift towards clean energy has led to a reduction in coal dependency, with the share of electricity in total energy consumption in Henan reaching 25%, an increase of approximately 5 percentage points since 2015 [9].
