New power system "stabilizer", construction of pumped storage power stations in 2023 is in full swing!

Pumped storage power stations are helpful to make up for the intermittency and volatility shortcomings of new energy sources, and are an important part of the new power system "voltage regulator", "regulator" and "memory". So it is also called a large "power bank".

Hydro energy storage is the leader in the field of energy storage in my country. In September 2021, in order to promote the rapid development of pumped hydro energy storage and adapt to the needs of new power system construction and large-scale and high-proportion new energy development To help my country achieve its "double carbon" goal as soon as possible, the National Energy Administration released the "Medium and Long-term Development Plan for Pumped Hydropower Storage (2021-2035)" (referred to as the "Plan"). The "Plan" proposes to speed up the approval and construction of pumped storage power stations, and in accordance with the principle of verifying what can be verified and developing what can be developed, the construction of pumped storage power stations should be approved in the key implementation project library of the plan. By 2025, the total scale of pumped storage energy production will double compared with the "13th Five-Year Plan", reaching more than 62 million kilowatts; by 2030, the total scale of pumped hydro energy storage will double compared with the "14th Five-Year Plan", reaching 120 million kilowatts. Around kilowatts.

In recent years, the construction of pumped storage power station projects in my country has accelerated, gradually turning into a "necessity" to ensure the safety of large power grids and promote the consumption of new energy. As of the end of 2021, the installed capacity of my country's pumped storage power stations reached 36.39 million kilowatts, ranking first in the world in terms of installed capacity of completed pumped storage power stations.

In 2022, my country's pumped hydro energy storage projects will usher in a historical peak period of approval and investment. According to data released by the Pumped Hydro Energy Storage Industry Branch on January 1, 2023, my country's pumped hydro energy storage projects in 2022 will The total approved scale of energy storage power stations is 68.9 million kilowatts, and the total investment exceeds 450 billion yuan, both five times higher than in 2021. The annual approved scale exceeds the total scale put into operation in the previous fifty years.

Moving forward to 2023, various places will drawThe hydro-storage power station is under construction!

On January 17, Zhejiang Jinshuitan Pumped Storage Power Station officially started construction. This is the first medium-sized pumped storage power station started under construction by State Grid Corporation of China this year. It is reported that the power station project is located in Yunhe County, Lishui City, Zhejiang Province, with a total planned investment of 2.49 billion yuan, a total installed capacity of 297,000 kilowatts, a designed annual power generation capacity of 297 million kilowatt hours, and a pumping power of 396 million kilowatt hours. It is expected to be put into operation in 2027.

On February 6, the Tongcheng pumped storage power station project was under construction in an intense and orderly manner. It is reported that the power station consists of an upper reservoir, a lower reservoir, a water delivery system, an underground powerhouse and a ground switch station. The total budgeted investment is 7.26 billion yuan, with a total installed capacity of 1.28 million kilowatts. The first unit is planned to generate power in October 2027. After it is completed and put into operation, it can effectively reduce the coal consumption of the power grid and improve the utilization rate of new energy. At the same time, it will also drive upstream and downstream industries and increase the output value of the power generation equipment manufacturing industry by approximately 2 billion yuan.

Recently, State Grid Xinyuan Hebei Fengning Pumped Storage Power Station, a pumped storage power station designed and constructed independently in my country and with the largest installed capacity in the world, is about to put its 8th unit into operation. The power station has a total installed capacity of 3.6 million kilowatts, and a total of 12 300,000-kilowatt reversible water pump turbine generator-motor units are installed. It is estimated that after the Fengning pumped storage power station is fully completed and put into operation in 2024, it will save 480,000 tons of standard coal and reduce carbon dioxide emissions by 1.3 million tons each year, promoting the clean and low-carbon energy transformation in North China.

Recently, the construction of the Funing pumped storage power station located in Funing District, Qinhuangdao City, Hebei Province is progressing steadily. It is reported that the power station consists of an upper reservoir, a lower reservoir, a water transmission system and an underground factory system, with a planned installed capacity of 1.2 million kilowatts. After it is completed and put into operation, it will be connected to the Beijing-Tianjin and Northern Hebei power grids with 500 kV lines and undertake multiple functions such as peak regulation, frequency regulation, phase regulation, energy storage, and system backup.

Environmentally friendly, low-carbon and clean energy is the only way for the world’s energy development! In the future, as the scale of pumped hydropower storage continues to expand and the operation and management system becomes more perfect, pumped hydropower storage will be more conducive to building a new power system with new energy as the main body, and help implement the national "double carbon" strategic goal. In addition, small and medium-sized pumped storage power stations are bound to usher in a new round of development opportunities due to their flexible layout, low investment, and quick results.
