In 2018, the average blackout time for Shenzhen full-caliber customers was 0.5 hours.

Build a world-class smart grid to help build a first-class bay area and a world-class urban agglomeration.
Power comes first in the development of bay area.  In 2018, the largest electricity consumption load of the whole society in Guangdong, Hong Kong, Macao and the Gulf region was about 90 million kilowatts, and the electricity consumption of the whole society was nearly 520 billion kilowatts (of which Hong Kong and Macao accounted for about 10%), with the per capita electricity consumption exceeding that of Germany.
Guangdong, Hong Kong, Macao and the Great Bay Area will build a first-class bay area and a world-class urban agglomeration with vitality and international competitiveness, which will bring great opportunities to the development of energy and electricity, and also put forward new requirements for high-quality development.  It is estimated that by 2035, the electricity consumption load in Guangdong, Hong Kong, Macao and Dawan will reach 130 million kilowatts, up nearly 50% from 2018.  The electricity consumption of the whole society reached 700 billion kilowatt hours, an increase of more than 40% over 2018.  Per capita electricity consumption exceeded 8,300 kilowatt hours, exceeding the current level in developed countries such as Germany and Japan, with an increase equivalent to the total electricity consumption of Hong Kong, Macao and Taiwan.  At the same time, the energy demand in Guangdong, Hong Kong, Macao and the Gulf region will be characterized by a high level of clean and low carbon, high safety requirements and diversified energy demand.
First-class bay area construction needs first-class power protection.  Cao Zhian, director, general manager and deputy party secretary of China Southern Power Grid Corporation, said that China Southern Power Grid is actively transforming into a smart grid operator, an energy industry value chain integrator and an energy ecosystem service provider. With the goal of building a world-class smart grid, China Southern Power Grid will further promote the planning and construction of smart grids in the Gulf region of Guangdong, Hong Kong, Macao and Taiwan, actively apply the key technology of "moving knowledge from big cloud to big object", continuously improve the quality of power supply service in the Gulf region of Guangdong, Hong Kong, Macao and Taiwan, give full play to the role of power grid in optimizing the allocation of resources and serving the green development platform, better protect the economic and social development of the three regions of Guangdong, Hong Kong, Macao and Taiwan, and meet the smart energy
Shenzhen, one of the core engines for the development of the Gulf region, like Paris, London and other international cities, Shenzhen power grid has the characteristics of high power supply reliability, high power quality and high load density.  At present, the 80 new substation sites above 220kv in Shenzhen have all been incorporated into the government's urban planning and will be built into intelligent substations.
Xu Daming, spokesman of China Southern Power Grid Corporation, said that China Southern Power Grid Corporation will invest more than 170 billion yuan in the Pearl River Delta power grid from 2018 to 2022 to speed up the planning and construction of smart grids in Guangdong, Hong Kong, Macao and the Gulf region, to continuously improve the power grid's ability to prevent and combat disasters, and to basically build a safe, reliable, green and efficient smart grid by 2022.  By 2030, Guangdong, Hong Kong, Macao and the Gulf region will take the lead in building a world-class smart grid to support the development of a modern economic system and the construction of smart city clusters in the Gulf region.
Reliable power supply is the key to the world-class smart grid.  The "26 Key Measures" put forward that the Southern Power Grid will continue to build and perfect the urban power transmission and distribution network, with the target that the average annual power outage time for customers in central urban areas of Guangzhou and Shenzhen will be less than 0.5 hours in 2020, and the average annual power outage time for customers in central urban areas of Zhuhai, Foshan, Huizhou, Dongguan, Zhongshan, Jiangmen and Zhaoqing will be less than 1 hour.  High-reliability power supply demonstration areas such as Guangzhou Zhongxin Knowledge City, Shenzhen Qianhai and Zhuhai Hengqin New District have been completed. The average annual power outage time of customers is less than 5 minutes, reaching the leading level of similar cities in the world.
The world's first-class smart grid will have a strong ability to prevent and combat disasters.  Guangdong, Hong Kong, Macao and the Gulf region are prone to natural disasters such as typhoons. The Southern Power Grid will speed up the construction of urban guaranteed power grids, carry out differentiated coastal power grid construction, carry out "cable lines+indoor stations" disaster prevention and disaster relief "lifeline" construction in coastal cities, optimize the distribution of disaster relief power supply and energy storage, and strive to ensure that the core areas of the city and key users do not have power outages and few power outages under extreme natural disasters.
The world's first-class smart grid, "smart" electricity use will become an important feature.  When a fault occurs in an external large power grid, the micro-grid system automatically detects the fault and disconnects the connection with the large power grid, enabling the energy storage device to supply power, and the whole process is less than 0.05 seconds.  This is a smart low-carbon microgrid project piloted in Nansha, Guangzhou.  The project adopts clean energy sources such as roof photovoltaic system, which can absorb 100% of the important load of clean energy nearby.
Zhang Wenfeng, director of the planning department of China Southern Power Grid Corporation, said that the company would coordinate the development needs and characteristics of Shenzhen Qianhai Shenzhen-Hong Kong Modern Service Industry Cooperation Zone, Guangzhou Nansha Guangdong-Hong Kong-Macao Comprehensive Cooperation Demonstration Zone and Zhuhai Hengqin Guangdong-Hong Kong-Macao Deep Cooperation Demonstration Zone, plan and build a smart energy system suitable for them, play a role of experiment and demonstration, improve the comprehensive energy service level and promote safe and efficient use of energy.
