In order to accelerate the implementation of carbon peaking and carbon neutrality action plans, a new power system will be constructed. On April 11, the reporter learned from the China Southern Power Grid Shenzhen Power Supply Bureau that in order to thoroughly implement the "Four Revolutions, One Cooperation" energy security strategy, the "Shenzhen "14th Five-Year" Power Grid Development Plan" was recently issued, and power grid investment will create a new new highs.

It is understood that in 2021, Shenzhen's power supply load density will reach 10,200 kilowatts per square kilometer, ranking first among large and medium-sized cities in the mainland. At the same time, the key core indicators of Shenzhen Power Grid have achieved breakthrough growth, and the salient features of world-class enterprises have become more prominent.

In terms of the construction of the main network, the production capacity and the number of newly built substations have reached a new high in the past 10 years. The grid has basically been built into a domestic leading grid with guaranteed bottom line, and it has taken the lead in passing the review of the National Energy Administration. In terms of distribution network construction, the high-quality power supply leading area of Houhai Business Headquarters was built, and the average annual power outage time for customers was only 0.48 minutes, reaching the world's top level; under the background of continuous load innovation, there was no frequent occurrence of heavy overloading of public transformers during the summer. Power outages and limited power consumption by customers; initially realized the visualization of intelligent operation and maintenance of the distribution network, reducing the number of households during power outages by about 25,200 in total throughout the year.

According to reports, the "14th Five-Year Plan" is a critical period for Shenzhen to build a modern, international and innovative city in an all-round way. Shenzhen Power Supply Bureau plans to invest a total of 47 billion yuan, an increase of about 36% compared with the "13th Five-Year Plan", to serve the high-quality development of Shenzhen's infrastructure. During this period, the scale of Shenzhen Power Grid will be further expanded, 110 substations are planned to be put into operation, and the high-quality development of Shenzhen's "20+8" industrial cluster and 20 advanced manufacturing parks will be fully supported. Comprehensively improve power supply security, promote the application of high-quality power supply technology, and the average power outage time for low-voltage customers is less than 10 minutes, reaching the world's leading level.

Shenzhen Power Supply Bureau will also make every effort to promote the development of the grid to be greener and smarter. By 2025, the city's installed power supply capacity will reach 20.33 million kilowatts, of which clean energy installed capacity accounts for about 90%; promote the construction of smart homes and smart communities, accelerate the construction of electric vehicle charging infrastructure, vigorously promote electric energy replacement, and serve Shenzhen's "double carbon" Target. At the same time, accelerate the implementation of 10 major new power system application scenarios, the new substations will account for 100% of the intelligent, and the 110kV and above lines will achieve full coverage of UAV intelligent inspections, and strive to complete the demonstration of Shenzhen’s new power system by 2025.
