On July 1, the Baihetan-Jiangsu ±800kV UHV DC project of State Grid Corporation of China was completed and put into operation. The project starts from Butuo County, Liangshan Prefecture, Sichuan Province, and ends in Changshu City, Suzhou, Jiangsu Province. It passes through 5 provinces, with a total length of 2,080 kilometers. Two new converter stations, Baihetan and Yucheng, are newly built. The rated voltage of the project is ±800 kV, the rated transmission capacity is 8 million kilowatts, and the total investment is 30.7 billion yuan.

Xin Baoan, chairman of State Grid, said in an interview with a reporter from China Economic Times that State Grid will resolutely shoulder the responsibility of ensuring power supply and energy transformation, and do a solid job in the operation and maintenance of the Baihetan-Jiangsu project to ensure the safe and stable operation of the power grid. Strengthen the State Grid's ability to optimize resource allocation, and better serve the high-quality economic and social development with the high-quality development of the power grid.

Xin Baoan introduced that the Baihetan-Jiangsu project was completed and put into operation, adding another energy artery that traverses the east and west for my country. It has significant comprehensive benefits and benefits for optimizing energy allocation, ensuring power supply, stimulating economic growth, promoting green development, and leading technological innovation. long-term strategic significance.

Promote the large-scale development and delivery of hydropower in Sichuan. Sichuan is rich in hydropower resources, with a technological development capacity of 148 million kilowatts, accounting for about one-fifth of the national total. The project can add 4 billion to 6 billion kWh of surplus hydropower in Sichuan's rich season every year, greatly improving the efficiency of hydropower utilization.

Strongly guarantee the safe and reliable supply of electricity in Jiangsu. It is expected that during the "14th Five-Year Plan" period, the power market space in Jiangsu will exceed 10 million kilowatts. The Baihetan-Jiangsu project is the second UHV project from Sichuan to enter Jiangsu after the Jinping-Sunan UHV project. The project cooperates with the existing UHV projects in East China to increase the proportion of clean energy consumption in Jiangsu, enhance the mutual aid capacity of water and fire in the power grid, help meet peak summer and winter peaks, and effectively alleviate the contradiction between medium and long-term power supply and demand in East China.

Unblock the new development pattern of domestic large-scale circular services. According to investment estimates, the construction of Baihetan-Jiangsu project, driven by innovation, led by high-quality supply and creating new demand, can increase the output value of power transmission and transformation equipment manufacturing industry by about 18 billion yuan, and drive investment in power supply and other related industries by about 100 billion yuan. It has created more than 20,000 jobs, promoted the economic growth of the regions along the Yangtze River, helped smooth the domestic circulation, and effectively served the construction of a new development pattern.

Promote environmental protection and help build a beautiful China. After the Baihetan-Jiangsu project is completed and put into operation, it will deliver more than 30 billion kWh of clean electricity every year, and promote the reduction of 14 million tons of coal for power generation in East China, 25 million tons of carbon dioxide, 250,000 tons of sulfur dioxide, and 220,000 tons of nitrogen oxides. Significantly improve the environmental quality in East China and promote the green transformation of Jiangsu's energy.

At present, the State Grid has built a total of 29 UHV projects. The UHV projects in operation and under construction have a line length of 45,000 kilometers. The substation (conversion) capacity exceeds 450 million kVA (kW), and the cumulative power transmission exceeds 2.6 trillion. kWh, the inter-regional and inter-provincial power transmission capacity has reached 240 million kW, which has significantly improved the long-distance power transmission capacity of my country's power grid and promoted the development of "transmitting electricity from the west to the east and supplying electricity from the north to the south".
