Shenzhen for two consecutive years in a row for less than half an hour

On June 24, the National Energy Administration released the national power reliability indicator in 2021, and Shenzhen ranked among major cities with an average annual power outage of less than 1 hour. According to statistics, the average power outage time in Shenzhen in 2021 was only 0.48 hours per household. It entered the "half -hour circle" for two consecutive years. It not only continued to lead in major cities across the country, but also better than New York and San Francisco to maintain the world's leading world.

Electricity is the lifeblood of economic and social development. In recent years, the Shenzhen Power Supply Bureau of Southern Power Grid has planned and constructed a strong power grid with the goal of "zero power outages". Urban positioning and high -quality development provide strong power guarantee for the construction of the "double district".

It is understood that Shenzhen cultivates and develops the "20+8" industrial cluster. The production characteristics of strategic emerging industries determine their extreme demand for power supply reliability and electrical energy quality. As a demonstration base for power supply reliability management management and national power reliability management of Southern Power Grid, the Shenzhen Power Supply Bureau proceeds from the source to build the world's top power grid planning technology system and grid planning system, and builds high -quality power supply leaders such as Shenzhen Bay District to create a high -end intelligent distribution network. In 2021, the investment was completed 9.3 billion yuan, and it was the first to pass the strong local power grid security assessment organized by the State Energy Administration to become the first city in the country to build a strong local power grid.

"Our precision production equipment has high requirements for power supply quality. Taking precision optical coating processing as an example, once the power outage is encountered, the entire production line may be abandoned before." In the production workshop, workers opened their horsepower to catch up. Zhang Yaghao, manager of the company's factory affairs department, said that the Shenzhen Power Supply Bureau provided them with two high -voltage lines to enhance the reliability of power supply. The company's electricity consumption increased by 8.2%year -on -year in the first quarter, and stable electricity strongly supported the increase in production.

The reliability of power supply is not only the grid structure, but also depends on the level of management. In response to the planning and repairs, the Shenzhen Power Supply Bureau establishes a distinctive comprehensive power outage management system. On the one hand, for the first time in China, the scheduling operation from the main network to the full voltage level of the distribution network is "one control to the end". Leading in the country. On the other hand, the 13 -prohibitaring demonstration zone was built and promoted to the city. Statistics show that in 2021, Shenzhen's non -stop power operating rate exceeded 95%, and the volume of cross -road crossing in the country ranked first in the country for 5 consecutive years. At present, the urban area plans to park the power outage basically achieved a "zero impact". The average planning time for users in Shenzhen for two consecutive years is less than 5 minutes, reaching the world's leading level.
