"Twelve Five" Jiujiang Power Grid Planning total investment of 6.6 billion yuan

In order to develop the economy, electricity must go first. This year, the city has further accelerated the pace of power grid construction, assisted in the development of large-scale development along the Yangtze River, and met the needs of construction and use of electricity in Jiujiang City and Poyang Lake Ecological Economic Zone. The reporter learned from the news briefing held by the city power supply company recently that during the “12th Five-Year Plan” period, the total investment of the city’s power grid planning was 6.592 billion yuan, which was twice the “Eleventh Five-Year Plan” investment. By 2015, Jiujiang Power Grid will support 500 kilovolts as its backbone and 220 kilovolts as a support, and a mixed network of radiation and ring networks will co-ordinate development of all levels of power grids. Intelligent technologies will cover all aspects of the power system, and Jiujiang's strong intelligence will be initially built. Grid.

This year, there are a total of 15 newly built and rebuilt projects in Jiujiang Power Grid, with a total investment of 1.574 billion yuan, and an investment of 700 million yuan during the year. It plans to add 730,000 kVA of main transformer capacity during the year, 57.1 kilometers of 220 kV line and 92.6 kilometer of 110 kV line. The powerful grid construction has provided a powerful guarantee for the economic development of Jiujiang.

According to reports, power demand in Jiujiang has continued to grow strongly in recent years. During the "Eleventh Five-Year Plan" period, the city's power grid scale, electricity sales and other major indicators have doubled from the "Tenth Five-Year Plan". During the "12th Five-Year Plan" period, it is forecasted that by 2015, the city's total electricity consumption and unified call power will be 14.51 billion kWh and 14.3 billion kWh respectively, with an average annual growth of 13.39% and 13.65% respectively; 2.55 million kilowatts, an average annual increase of 12.1%. During the "12th Five-Year Plan" period, the city plans to build 839 kilometers of 110 kV and above lines, with a capacity of 4.7 million kVA. By 2015, the length of 110 kV and above lines will reach 3052 km, and the capacity will be 10.47 million kVA, which is 1.38 times and 1.86 times that of 2010 respectively. During the “12th Five-Year Plan” period, the city will gradually build a 500 kV grid main grid. At the same time increase the number of substations and optimize the structure of the grid. Through the construction of power generation, transmission, substation, power distribution, power supply, dispatch, and communication information platform, the level of informatization, automation, and interaction of Jiujiang Power Grid will be comprehensively improved, thus forming the intelligentization of Jiujiang Power Grid.

At present, the projects under construction in the city are 500 kilowatts of Maweiling, 220 kv of red light, and 110 kV Jidong Power Transmission and Transformation Project; the project that has been put into operation has a 220 kV Jiuhua Power Transmission and Transformation Project; The project to start construction includes 500 kV Shizhongshan-Hongyuan Transmission Line Project; 220 kV Duchang Power Transmission and Transformation Project, Jiujiang Xingang Substation Main Transformer Expansion, Mahuiling Substation Power Transmission Line, Jiujiang Power Plant Phase IV Transmission Line, Repair Shui Yeshan Second Power Line Project; 110kv Laoshan District Gutang, Xiushui Liangtang Power Transmission and Transformation Project, Jishan Wind Power Transmission Line Project. After these projects are completed and put into operation, they will meet the requirements of Jiujiang Power Plant's “Shangmao Small Press” unit access system, and power supply to Huguang, Pengze, Duchang and other industrial parks in Dongsan County, Jiujiang and Jiujingu Electrified Railway. The Shenhua coal-fired power project will be sent out and the small-scale hydropower transmission in the western area will provide stronger power security.
