China News Service, Guangzhou, May 29 (Wang Hua Lanwang) China Southern Power Grid Corporation announced on the 29th that two million kilowatt-level pumped storage power stations invested and constructed by the company will be put into operation at the same time.
So far, the Guangdong-Hong Kong-Macao Greater Bay Area power grid has a total installed capacity of pumped storage of nearly 10 million kilowatts, making it a world-class bay area power grid with the largest installed capacity of pumped storage, the strongest power grid regulation capability, and the highest proportion of clean energy consumption in the world.
Two million kilowatt-level pumped-storage power stations built by China Southern Power Grid Corporation in Meizhou and Yangjiang, Guangdong, were put into operation on the 28th.
The two pumped-storage power stations have a total installed capacity of 2.4 million kilowatts, which will increase the power grid regulation capacity of the Guangdong-Hong Kong-Macao Greater Bay Area by more than 30%, effectively promote the large-scale and high-proportion access of new energy, and make the Guangdong-Hong Kong-Macao Greater Bay Area peak power during peak hours. The power supply capacity has been greatly improved, which is equivalent to increasing the power supply capacity of nearly two Hainan provinces.

As a result, the installed capacity of pumped storage in the southern region (five provinces and regions) has reached 10.28 million kilowatts, of which the installed capacity of pumped storage in the Guangdong-Hong Kong-Macao Greater Bay Area has reached 9.68 million kilowatts, creating a demonstration bay area for the use of clean energy in the world for the Guangdong-Hong Kong-Macao Greater Bay Area. Provide support.
At present, the maximum load demand of the Guangdong-Hong Kong-Macao Greater Bay Area during the day is about 100 million kilowatts, while the nighttime trough is only about 30 million kilowatts. More clean electricity such as wind power and hydropower.
According to estimates, the Guangdong-Hong Kong-Macao Greater Bay Area power grid, which has a total installed capacity of pumped storage of 10 million kilowatts and accounts for 13.8% of the average load of the grid at full power, can support the consumption of more than 210 billion kWh of clean energy throughout the year, and the proportion of clean energy is close to 50%.

After the two pumped-storage power stations are fully put into operation, they will further promote the consumption of new energy in the Guangdong-Hong Kong-Macao Greater Bay Area. It is estimated that 3.4 billion kWh of peak-shaving electricity can be optimized throughout the year, corresponding to a reduction of 2.8 million tons of carbon dioxide emissions, and the emission reduction effect is equivalent to nearly The purification effect of 220,000 mu of forest.
"The total investment of the two power stations is about 15 billion yuan (RMB, the same below). In addition to the considerable power regulation benefits, its construction and operation can also drive investment of about 30 billion yuan in the upstream and downstream industrial chains and create about 7.4% of jobs. Ten thousand." said Liu Guogang, chairman of China Southern Power Grid's peak and frequency regulation power generation company.
The construction of the two pumped-storage power stations has significantly driven the development of upstream and downstream industrial chains, supply chains, and innovation chains.
According to statistics, a total of 121 participating units have been involved in the construction of the two pumped-storage power stations from the start of the main project to the start of production, and 87 major key technologies have been successfully conquered.
It is estimated that each pumped-storage power station will increase local fiscal revenue by about 100 million yuan each year after it is put into operation.
