Annual power supply will break 80 billion
Power supply load the third in the province
In the first half of 2018, Dongguan achieved a regional GDP of 386.86 billion yuan, a year-on-year increase of 7.8%, ranking fourth in the province. Economic development, electricity first, the people and industrial and commercial enterprises are increasingly demanding electricity security. Guangdong Power Supply Bureau of China Southern Power Grid introduced the current situation of power supply and power grid construction in the city. It is reported that from September 2017 to September 1818, Dongguan completed a total investment of 7.551 billion yuan in power grids and built a power grid project of 110 kV and above. There are 17 projects, 11 reserves, and 2,837 distribution network projects. It is estimated that the investment for this year will be 3.738 billion yuan, 13 power grid projects with 110 kV and above will be built, 15 projects will be started, and 14 reserves will be built. 1778 web projects.
Although the construction of Dongguan Power Grid continues to accelerate, the current and future supply and demand situation is still not optimistic. According to reports, in 2017, the total electricity consumption of Dongguan City exceeded 70 billion mark, reaching 76.068 billion kWh, an increase of 8.36. Since 2018, the city's power load has reached a record high five times. As of the end of September, the power supply load reached 15.5453 million kilowatts, a year-on-year increase of 3.91%, ranking in Guangzhou, after Shenzhen, the province ranked third, the country ranked first Seven.
With the strong promotion of the construction of the Guangzhou-Shenzhen Science and Technology Innovation Corridor in Dawan District, Guangdong, Hong Kong and Macao, Huawei terminals, Lansi Technology, BBK series and other enterprises have increased their capital to settle in Dongguan, and the electricity load is suddenly increasing. It is expected that the power supply in Dongguan will reach 2018. 82.15 billion kWh. According to the special plan of Dongguan Power Grid, it is estimated that by 2020, the power supply load in Dongguan will reach 18 million kilowatts, and it still needs to increase by about 2.5 million kilowatts.
In recent years, Dongguan's electricity supply, especially industrial electricity consumption, has been leading the provinces and cities. However, compared with other areas with the same total power load, the scale of Dongguan's power grid is obviously small, which is difficult to match the scale of Dongguan's economy. Further improvement.
Get through the 'last mile'
Dongguan Smart Grid will be completed by 2020
As a famous manufacturing city in Dongguan, Dongguan has successively put forward development strategies such as 'Dongguan Manufacturing 2025', 'Urban Quality Improvement' and 'Enterprise Multiplication Plan'. Under this background, Dongguan City launched the power grid planning and construction conference from 2014 to 2016. ' From 2017 to 2020, Dongguan's 'Grid Upgrade Action' will be launched to promote power grid construction and help urban development. The three-year 'conference battle' has laid a solid foundation, and the power grid upgrade will focus on improving the power supply quality of the power grid and strengthening the reliability of power grid operation. .
During the power grid upgrade, the construction of Dongguan Power Grid Project has obviously accelerated. Up to now, 10 substations of 110 kV and above have been added, 25 new transformers have been added, and the newly added substation capacity is 3.397 million kVA. The newly put into operation 220 kV Ran Station, 110 kV Shangjiao Station and Shebe Station effectively alleviated the power gap in Dalang, Chang'an, Huangjiang and other towns and streets; meanwhile, the second phase of the 500 kV line project of Longjiang River was put into operation, strengthening the southwestern part of Dongguan Power Grid Power supply security in the core area of the load. Dongguan Power Grid is stronger and more reliable, and the reliability of power supply has been greatly improved. In the first half of this year, Dongguan ranked second in the power supply reliability ranking of major cities in China.
According to the plan, in 2018-2019, Dongguan plans to invest about 7.5 billion yuan to build power projects, build 34 power grid projects of 110 kV and above, start 33 projects, reserve 40 projects, and upgrade and upgrade 5,200 distribution network projects. Under the strong leadership of China Southern Power Grid, Guangdong Power Grid Corporation and Dongguan Municipal Party Committee and Municipal Government, the bureau will open a 'last mile' for power grid construction, create a good grid construction environment, and intensify efforts to promote a new round of power grid construction projects.
By the end of 2020, the reliability of power supply in the main network of Dongguan will continue to increase, and the intelligentization of distribution network automation will be significantly improved. Among them, the distribution network can be transferred to the power supply rate, the distribution network automation coverage rate, the distributed photovoltaic project access rate, The four indicators of smart meter coverage have achieved 'four 100%', 'safe, reliable, efficient, green' Dongguan smart grid has been basically built to provide better power services for Dongguan's economic and social development.
Completed and built Dongguan Power Grid
Improve quality and efficiency to meet people's electricity needs
In recent years, the Dongguan Power Supply Bureau has made great efforts to strengthen the power grid, ensure power supply, and excellent services, and to help improve the quality of Dongguan's cities, and implement the important strategies such as the “multiple-increasing plan”. The power grid planning and construction has achieved certain results.
However, some power projects encountered '尴尬' situation when they settled in. As an example, Nancheng International Business District - Dongguan CBD, which is enclosed by Dongguan Avenue, Huancheng West Road, Sanyuan Road, Hongtu Road The gold area formed has an area of about 2.14 square kilometers. 'According to the load forecast of Dongguan CBD special power plan, the new load will reach 225,000 kilowatts. According to the load ratio of 2.1, three 110 kV substations need to be built. 'Dongguan Power Supply Bureau According to the relevant staff of the Planning and Development Department, the current CBD and surrounding areas of Dongguan are mainly supplied by the surrounding Xiping Station, Zhouxi Station and Yinfeng Station. The load rates of Xiping and Yinfeng Station in 2018 are more than 50%, and three substations 10 The kilovolt interval outlets have been used up. In order to meet the electricity demand of the CBD in Dongguan, it is urgent to put into production new power transmission and transformation projects nearby.
However, the related power transmission and transformation project failed to land as planned. The staff introduced that the practical experience of power development shows that the power grid construction must be appropriately ahead of economic and social development, and one of the characteristics of power grid construction is that the construction period is long. In the case of obtaining substation land and route route agreement, the preliminary processing of the 110 kV substation takes two and a half years, and the reasonable period of construction of the project is 13 months; the construction period of the 220 kV substation is longer, and the previous period takes three years. Construction will take 18 months. '
Dongguan Power Supply Bureau will identify the current focus of power grid construction, increase efforts, speed up the progress, closely track the hot spots of economic growth, plan ahead to increase the distribution of substations in urban areas, key industrial parks, etc., enhance power supply capacity, and ensure that power grid construction projects must be completed. Cheng, built and built Dongguan Power Grid.
In recent years, Dongguan City is committed to building an advanced manufacturing center in Dawan District of Guangdong, Hong Kong and Macao, and accelerating its progress towards innovative first-tier cities. The Dongguan Power Supply Bureau will seize the historical development opportunities of Dongguan's comprehensive deepening reform, and further on the basis of the 'Grid Upgrading Action'. Improve quality and efficiency, ensure a successful victory in power grid upgrades, meet the growing needs of Dongguan's economic and social development and people's lives.
