Core Insights - The "Chuan Dian Ru Su" ultra-high voltage transmission projects have delivered over 505 billion kilowatt-hours of clean hydropower to Jiangsu, significantly contributing to energy structure optimization and green low-carbon development [1][2] Group 1: Project Impact - The two ultra-high voltage direct current transmission projects, ±800 kV Jinping-Su Nan and ±800 kV Baihe-Tan-Jiangsu, have collectively saved over 150 million tons of standard coal and reduced carbon dioxide emissions by more than 475 million tons [1] - These projects effectively address the structural contradiction between energy-rich regions and energy-demanding areas, optimizing the allocation of green electricity resources across regions [1] Group 2: Energy Demand and Supply - Jiangsu, as a major economic and energy-consuming province, has a strong energy demand, while Sichuan possesses abundant hydropower resources, making the projects crucial for energy supply [1] - The Jinping and Baihe-Tan hydropower bases supply approximately 55 billion kilowatt-hours of electricity to Jiangsu annually, accounting for about 30% of Jiangsu's total electricity consumption from outside the province [1] Group 3: Technological Advancements - The Jinping-Su Nan project, operational since 2012, was a technological milestone with a direct current transmission capacity of 7.2 million kilowatts, representing the highest level of ultra-high voltage direct current technology at that time [1] - The Baihe-Tan-Jiangsu project, completed in 2022, has a maximum transmission capacity of 8 million kilowatts, further enhancing the clean energy absorption capacity and operational resilience of the East China power grid [1] Group 4: Environmental and Economic Benefits - Over the past decade, Jiangsu has achieved an average energy consumption growth rate of 3% and a carbon emission growth rate of 1.5%, supporting an average GDP growth rate of 6.5%, indicating a significant increase in the region's "green" development [2]

Core Insights - The "Chuan Dian Ru Su" ultra-high voltage transmission project has delivered over 505 billion kilowatt-hours of clean hydropower to Jiangsu, significantly contributing to energy structure optimization and green low-carbon development [1] Group 1: Project Overview - The two key ultra-high voltage projects, ±800 kV Jinping-Sunan and ±800 kV Baihetan-Jiangsu, serve as vital energy corridors connecting western clean energy bases with eastern electricity load centers [1] - These projects are part of China's "West-to-East Power Transmission" initiative, addressing the energy supply-demand imbalance between resource-rich areas and economically developed regions [1] Group 2: Environmental Impact - The energy delivered has resulted in the saving of over 150 million tons of standard coal and a reduction of more than 475 million tons of carbon dioxide emissions [1] Group 3: Regional Energy Dynamics - Jiangsu, as a major economic and energy-consuming province, relies heavily on these projects, which account for approximately 30% of Jiangsu's total electricity consumption from external sources [1] - The Jinping and Baihetan hydropower bases supply around 55 billion kilowatt-hours of electricity to Jiangsu annually, making them the most important source of cross-regional power for the province [1]
