The 244 energy guarantee of the Guangdong -Hong Kong -Macao Greater Bay Area for key engineering projects to speed up, and it is expected to be fully completed and put into production in 2025

Southern Finance and Economics reporter Huang Haobo Guangzhou reported on July 6. On July 6, a reporter from Southern Finance and Economics learned from the Southern Power Grid Corporation that the 244 energy guarantee of the Guangdong -Hong Kong -Macao Greater Bay Area was fully accelerated in the construction of key engineering projects. 125 items were put into production this year.

According to reports, the 244 energy insurance supply projects that have been accelerated in an all -round way mainly include key engineering projects in the second phase of Guangdong target network shelf, key power supply supply projects, and pumping energy storage projects. The industrial chain investment is 150 billion yuan.

The power supply capacity of the Guangdong -Hong Kong -Macao Greater Bay Area is doubled

In Huangpu District, Guangzhou, Guangdong, the 500 -kilovolt -in -family power transmission and transmission project is planned to be put into production at the end of this year. As the first batch of 500 kV autonomy and controllable demonstration projects in Southern Power Grid Corporation, the total investment of the project is 570 million yuan, involving more than 20 upstream and downstream companies in the industry. It is expected that the industrial chain investment can invest about 1 billion yuan.

In fact, in order to effectively improve the safety and stability level and clean energy configuration capabilities in the Guangdong -Hong Kong -Macao Greater Bay Area, Southern Power Grid has arranged a fixed asset investment of 78.7 billion yuan in the Guangdong -Hong Kong -Macao Greater Bay Area this year. As of the end of May, a total of 30.1 billion yuan has been completed. The two million kilowatts of water pumping power stations in Meizhou and Yangjiang, Guangdong, and Yangjiang were completed, and the project of DC backbone grid in the middle and South Channel DC backbone of the DC and South Channel was built.

As a key project of the "Fourteenth Five -Year Plan" of the Energy Development of Guangdong Province, on May 25, the DC backbone grid of the Guangdong -Hong Kong -Macao Greater Bay Area was officially put into operation. For the first time in the world, the project conducted a reasonable partition and flexible interconnection for the complex structure of the power grid. The level of security and stability of the Guangdong -Hong Kong -Macao Greater Bay Area has been greatly improved.

"The project enables the AC power system to connect independently through DC, just like the two people who" back to the back 'usually' support each other ', and encounter the failure of the failure' to let go. " General Manager Pang Peng said.

According to estimates, after all the series of projects marked by the Guangdong -Hong Kong -Macao Greater Bay Area DC backbone grid project are put into production, the power supply capacity of the Guangdong -Hong Kong -Macao Greater Bay Area will increase by 80%. At the same time, the Guangdong -Hong Kong -Macao Greater Bay Area DC backbone grid project also involves more than 200 upstream and downstream enterprises in the industrial chain, which can drive about 8 billion yuan.

Optimizing the construction of power grid is the key task of Guangdong's efforts to enhance the guarantee of energy security. According to the "Fourteenth Five -Year Plan" of Energy Development in Guangdong Province, Guangdong will steadily implement the construction of the target network shelf in the Guangdong -Hong Kong -Macao Greater Bay Area, and build a 500 kV outer ring network in the Guangdong -Hong Kong -Macao Greater Bay Area. Flexible DC interconnection main network frame pattern. Comprehensively promote the construction of modern power grids of security, reliability, green, efficient, and intelligent.

"Building a target grid is to improve the transportation capacity of the grid channel and ensure that sufficient power energy is transported to the Greater Bay Area to meet the needs of economic and social development." Xie Rongchang, deputy general manager of the infrastructure department of Guangdong Power Grid Guangdong Power Grid Company, introduced that the current Guangdong -Hong Kong -Macao Greater Bay Bay Bay is introduced. The maximum electricity load of the district is about 100 million kilowatts per day. After all the Guangdong target network shelf projects are completed and put into operation, the power supply capacity of the Guangdong -Hong Kong -Macao Greater Bay Area will be increased from the previous 100 million kilowatts to 200 million kilowatts. In half an hour.

Promote the construction of 29 new power system demonstration areas

In recent years, the Guangdong -Hong Kong -Macao Greater Bay Area has accelerated the construction of a new type of power system. At present, it has initially established the "Yuanwanghe Chu" coordinated Greater Bay Area comprehensive energy supply guarantee system.

Shenzhen took the lead in building a diversified interactive system with the "source network lotus storage" with virtual power plants as the core and put into actual operation; Guangzhou initially built high reliability power distribution of 20 kV petals and distribution grids of Guangzhou Sino -New Knowledge City, Zhuhai Hengqin network.

According to reports, in order to help the Guangdong -Hong Kong -Macao Greater Bay Area achieve carbon peaks, carbon neutrality, Southern Power Grid will accelerate the construction of 29 new power system demonstration areas in Guangdong.

Due to the different resource endowments and basic conditions of various demonstration areas, the demonstration will be carried out in layered classification according to local conditions. For example, in Shenzhen, Guangzhou, Huizhou and other new power system demonstrations, carry out demonstrations of new county -level power systems in Nansha and Zhuhai Hengqin in Guangzhou, and carry out new power system demonstrations in park -level and district -level power systems in Songshan Lake in Dongguan.

At the same time, Guangdong will explore new technologies and new formats such as the "large -scale car network interaction", "5G+power grid deep integration", "low -carbon park comprehensive energy supply", etc., and accelerate the improvement of the flexible, flexible adjustment, and diverse interactive capabilities of the power system to ensure the improvement of the power system. In the "Fourteenth Five -Year Plan" period, Guangdong basically built a new power system demonstration area.

"At present, we are accelerating the preliminary work of Huizhou Zhongdong and Zhaoqing Langjiang River pumping projects, and make every effort to ensure that the two projects start successfully this year." According to Li Changjie, deputy general manager of the infrastructure department of the Southern Power Grid Summit, we said.

According to Li Changjie, after the two pumping storage projects of Huizhou Zhongdong and Zhaoqing Langjiang, the power grid adjustment ability will increase by nearly 25%. The leading advantage will also be further consolidated to effectively promote the energy security guarantee and energy storage system in the Guangdong -Hong Kong -Macao Greater Bay Area.
