Sichuan's electricity can "run together" in less than 1 second. This morning, the Baihe Beach -Jiangsu ± 800 kV high -voltage DC project was officially launched.

Baihe Beach -Jiangsu Special High -pressure Project starts in Budao County, Liangshan Prefecture, Sichuan Province. It ends in Changshu City, Suzhou, Jiangsu Province. , Yucheng 2 streaming stations. The total investment was 30.7 billion yuan, which started construction in December 2020, and launched electricity in July 2022.

After the Baihetan -Jiangsu UHV Project is completed, a large energy artery of East and West will be added to optimize energy configuration, ensure power supply, stimulate economic growth, promote green development, and lead technological innovation with significant comprehensive benefits and long -term strategies significance.

Promote the large -scale development and delivery of Sichuan hydropower. Baihetan -Jiangsu UHV Project is completed and put into production, which can ensure the large -scale delivery of electric power stations in the Baihetan Hydropower Station and promote the transformation of Sichuan resources into economic advantages. The project can also use the full -time surplus power supply capacity of the channel. Each year, Sichuan Fengqi Fuyou Hydropower is about 4 billion kWh, which greatly alleviates Sichuan water abandonment.

Effective protection of Jiangsu's power safe and reliable supply. Baihe Beach -Jiangsu UHV Engineering transmission capacity reaches 8 million kilowatts, which can meet the development needs of local economic and electricity and load development in Jiangsu. This project has the cooperation with UHV projects in East China. The advantage of loss, increase the proportion of clean energy in Jiangsu, enhance the ability to help each other in the power grid, and effectively alleviate the contradiction between the medium and long -term power supply and demand in East China.

After the Baihetan -Jiangsu UHV Project is put into operation, the annual cleaning of clean electricity can exceed 30 billion kilowatt -hours, which can reduce the annual reduction of 14 million tons of coal used in East China, 25 million tons of carbon dioxide, 250,000 tons of sulfur dioxide, 22 nitrogen oxides 22 10,000 tons can significantly improve the environmental quality of East China and provide strong support for achieving the "dual carbon" goal.

According to investment estimates, the construction of the Baihetan -Jiangsu special high -voltage project can increase the output value of transmission and transformation equipment manufacturing about 18 billion yuan, drive about 100 billion yuan in related industries such as power supply, and increase employment of more than 20,000. Economic growth in various places.

Baihe Beach -Jiangsu UHV Project is the world's first hybrid joint -level joint high -voltage DC project. In the world, it has developed a "conventional DC+flexible DC" hybrid link -level united high -voltage DC transmission technology for the first time. Among them, the controllable self -recovery and consumer energy device can quickly achieve millisecond energy balance, greatly improving the power of East China Power Grid.
