On April 23, 2021, the reporter learned from the Hefei Power Supply Company that the 110 kV South China City Substation was officially connected to the grid. This is the first "government-enterprise co-construction" power transmission and transformation project put into operation in Hefei, which can better meet the needs of urban and rural integration. The development of electricity demand. According to the plan, the total investment in Hefei's new round of large-scale power grid construction during the "14th Five-Year Plan" period will exceed 14 billion yuan, which will provide strong energy support for economic and social development.

"Government and Enterprise Co-construction"

The 110kV South China City Power Transmission and Transformation Project includes three single projects, including the main substation and the disconnection of Zhuyun I and II lines into the South China City Power Station. The main station is located at the intersection of Huasan Road and Huasi Road in Taohua Industrial Park. It provides power users with 30 cycles of 10 kV outlets at a time. The station is planned to be further expanded in the long term. The station is the first 110 kV indoor substation in Feixi. It uses domestic advanced indoor fully enclosed combined electrical equipment and other equipment, which is in line with the current energy-saving, green and environmentally-friendly construction of power grids.

In recent years, Hefei City’s urban-rural integration development process has progressed steadily. Feixi County, which ranks first in the country’s top 100 counties in Anhui, has achieved economic and social development by leaps and bounds, which has directly led to a substantial increase in regional electricity consumption. At the same time, large industrial users have Dedicated power supply lines are in strong demand. To this end, under the efficient mechanism of government-enterprise collaboration, the Hefei Power Supply Company is closely linked to the overall urban and rural planning and development, and continues to optimize the "14th Five-Year" power grid planning and distribution plan. By creating a good environment to ensure the rapid construction and stable implementation of large-scale power grid projects, it effectively guarantees the energy demand of the whole society.

The 110kV South China City Substation is the first "co-construction of government and enterprise" power transmission and transformation project that is actively explored by Hefei City, invested and constructed by the government in the early stage, and managed and maintained by the power supply company in the later stage. The station goes deep into the load demand center, further enhances the grid structure of the southwestern area of Hefei, shortens the power supply radius, satisfies the power demand for the development of industry, manufacturing and logistics in the region for a period of time, and effectively reduces the power supply pressure during peak power consumption.

Urban development and electricity go first. This year is the key year for the start of the "14th Five-Year Plan". Hefei Power Grid plans to invest 3.87 billion yuan to build 47 power grid projects of 110 kV and above, and put into operation 13 large substations of 110 kV and above. As of April 21, 6 substations have been put into operation on schedule, laying a solid foundation for the smooth operation of the power grid this summer, and effectively escorting local economic development and electricity demand. According to the latest plan, during the entire "14th Five-Year Plan" period, the total investment in Hefei's large-scale power grid construction will reach 14.2 billion yuan. Feixi, Lujiang, Feidong and the main urban area will each build four 500kV substations, which will be 110kV and above. There are 94 large-scale substations. By the end of the "14th Five-Year Plan" period, Hefei Power Grid will form a more scientific power supply pattern, further improve the reliability of regional power supply, and effectively promote the integrated development of Hefei's urban and rural areas. Editor/XuNing、 Design/ZhangTao
