China Southern Power Grid will invest about 200 billion yuan in the construction of pumped storage projects in the next ten years

Recently, China Southern Power Grid Corporation held a mobilization meeting for pumped storage construction

The three pumped storage power stations in Zhaoqing, Guangdong, Zhongdong, Huizhou, and Nanning, Guangxi, have a total installed capacity of 3.

Meng Zhenping, chairman and party secretary of China Southern Power Grid, said that China Southern Power Grid is actively promoting the development of pumped storage.

The installed capacity of pumped storage in the five southern provinces will increase by 4.

Achieving the goal of carbon peaking and carbon neutrality and building a new power system with new energy as the mainstay are major decisions and deployments made by the Party Central Committee and the State Council

"The new power system takes new energy as the main body, wind power, photovoltaic and other new energy as the main body.

In recent years, the scale of installed pumped storage capacity in China has increased significantly, and the scale of both built and under construction ranks first in the world

In September of this year, the National Energy Administration issued the "Pumped Storage Mid- and Long-Term Development Plan (2021-2035)" and stated that accelerating the development of pumped storage is an urgent requirement for building a new power system with new energy as the main body and a guarantee for the power system.

　　China Southern Power Grid issued the "Company's Opinions on Promoting the Transformation of Green and Low-Carbon Development" and stated that it will speed up the construction of pumped storage in the next three five-year plans.
During the 16th Five-Year Plan, the newly installed capacity will be 15 million kilowatts, which will increase by 4.
6 times in the next 15 years
.
By 2030, it will be roughly equivalent to the installed capacity of a new Three Gorges hydropower station, supporting the access and consumption of new energy sources of more than 250 million kilowatts
.

　　The installed capacity of pumped storage under construction in the five southern provinces reaches 6 million kilowatts

　　“Pumped-storage power stations use surplus electric energy to pump water from the lower reservoir to the upper reservoir for storage during the trough of electricity consumption; at the peak of electricity consumption, the water from the upper reservoir is used to generate electricity to make up for the power supply gap in the grid
.
” Li Dinglin, deputy general manager of the Grid Peak and Frequency Modulation Company, introduced that pumped storage power stations, as an important regulation method of urban power grids, have the advantages of flexible operation and fast response, and are known as the "regulators", "voltage regulators" and "regulators" of large power grids.
Power Bank"
.

　　In the face of the current shortage of power supply, the China Southern Power Grid Corporation's peak-regulation and frequency-regulation power station, as an important tool for stabilizing the large-scale power grid, gives full play to the role of peak-shaving and valley-filling to ensure power production
.
According to statistics, the total peak shaving time of the five pumped storage power stations in September was 8,541 hours, which is 125% of this year's average and an increase of 38% over the same period last year, effectively improving the power supply capacity of the five southern provinces
.

　　The three pumped-storage power stations accelerated this time are all key construction projects in the National 14th Five-Year Plan
.
Among them, Guangdong Zhaoqing Langjiang and Huizhou Zhongdong pumped storage power stations will optimize the local power supply structure after completion, better realize energy clean and low-carbon transformation, and effectively promote the construction of energy security and energy storage systems in the Guangdong-Hong Kong-Macao Greater Bay Area, and help construction A world-class bay area
.
It is worth mentioning that Zhaoqing Langjiang and Huizhou Zhongdong Pumped-storage Power Stations are the first to use variable-speed units in five southern provinces and regions.
Compared with fixed-speed pumped-storage units, they can provide more flexible, fast, efficient and reliable adjustment capabilities.
, Can better adapt to the fluctuation characteristics of new energy
.
Guangxi Nanning Pumped-storage Power Station is the first pumped-storage power station in Guangxi.
It will help Guangxi achieve carbon peak and carbon neutral goals, meet the rapid growth of electricity demand in the power system, promote the development of clean and low-carbon energy transformation, and contribute to the economic and social development.
Quality development adds power support
.

　　In addition, China Southern Power Grid has currently built two pumped storage power stations in Meizhou and Yangjiang, Guangdong, with installed capacity of 1.
2 million kilowatts.
Ability to alleviate the shortage of electricity during peak hours
.
It is expected that after each power station is put into operation, it will promote the development of local commerce and tourism, and increase local fiscal revenue by about 100 million yuan each year
.

　　As the only enterprise specializing in the construction and operation and management of peak-shaving and frequency-modulation power supply within the five southern provinces and regions, China Southern Power Grid’s wholly-owned subsidiary Peak-shaving and Frequency-Regulation Company will do a good job in environmental protection and water conservation in the whole process.
, Save land, save water, save materials, and protect the environment to minimize damage to the environment and natural ecology
.
China Southern Power Grid Peaking and Frequency Regulation Corporation has won many important awards such as "National Quality Project Award", "China Power Quality Project", and "First Prize of Science and Technology Progress Award of China Dam Engineering Society"
.
Among them, Guangxi Pumped Storage Power Station and Lubuge Power Station were also rated as "100 Classic and Excellent Projects for the 60th Anniversary of the Founding of New China", and Qingshui Pumped Storage Power Station won the so-called "Nobel Prize in Engineering" in September this year.
"Fidic Excellent Engineering Award"
.

　　China Southern Power Grid has now completed 5 pumped storage power stations and put into operation the first domestic megawatt battery energy storage station.
Since operation, safe production has continued to be stable, maintaining a zero record of safe production accidents, and improving grid regulation capabilities and The clean energy absorption capacity also brings significant ecological benefits.
During the "13th Five-Year Plan" period, a total of 15.
7 million tons of standard coal was saved for the system, which is equivalent to a reduction of 127 million tons of carbon dioxide emissions and a reduction of 3.
8 million tons of sulfur dioxide emissions
