With the completion of the three-phase impact closing power transmission of the 220 kV Keppel line, the start and commissioning of the 500 kV substation expansion project of Baoligen was successfully completed, marking the smooth operation of the 500 kV power grid project - the expansion project of the 500 kV substation.
The expansion project of Baoligen 500 thousand volt substation is the first batch of large-scale wind and solar bases in the country (Xilin Gol League UHV Transmission Phase II 4 million kilowatt new energy) supporting projects, and the Inner Mongolia Autonomous Region's 2023 emergency energy supply guarantee project. The expansion scale is based on the original main transformer capacity of 2 750,000 kVA of Baoligen 500 kV substation, and the new 1 group of 1 million kVA main transformer and three 220 kV outlet spacing, with a total investment of 141.91 million yuan.
The expansion project started on June 27 and lasted 168 days of construction and was put into operation smoothly, realizing the speed of "starting construction and putting into operation in the same year", ensuring the synchronous construction and operation of the network source, and contributing to the acceleration of the construction of the power system with new energy as the main body in Xilin Gol League.
After the expansion project is completed and put into operation, it will meet the demand for new energy transmission and 1 shared energy storage power station of 2 Taifu Energy projects with a total of 1 million kilowatts in Xilinhot City, saving 110 standard coal annually70,000 tons, reducing carbon dioxide emissions by 24360,000 tons to promote the low-carbon, green, clean and sustainable development of the energy industry in the Xilin Gol League.
