Construction of hybrid pumped storage power station in Lianghekou.
Details are as follows. Sichuan——
The construction of major energy facilities projects is in full swing
In the traffic hole into the factory, people come and go, and the machine roars. On February 18, in the Lianghekou Hybrid Pumped Storage Power Station area of the Yalong River Basin Hydropower Company in Yajiang County, Ganzi Tibetan Autonomous Prefecture, Sichuan Province, the builders of the construction site held tools to speed up the project operation.
The project is the implementation project of the 15th Five-Year Plan of the National Medium and Long-term Development Plan for Pumped Storage (2021-2035), and it is also a key project in Sichuan Province in 2024. Zhang Dongming, director of the Lianghekou Pumped Storage Construction Administration Bureau of Yalongjiang Company, said that in December 2022, the Lianghekou Hybrid Pumped Storage Power Station was approved to start construction, and now the excavation and support of the traffic tunnel of the power station has been completed for 1,350 meters, and more than 800 meters remain.
According to reports, the pumped storage power station project plans to install four 300,000 kilowatt reversible units, plus the completed Lianghekou hydropower station 3 million kilowatts of installed capacity as a conventional unit, the first unit will reach 4.2 million kilowatts. According to the balance of pumped water, the annual power generation is 13At 9.7 billion kilowatt hours, it is a super-large hybrid "power bank".
The Lianghekou Hybrid Pumped Storage Power Station can promote the construction of tens of millions of kilowatts of renewable energy base in the middle reaches of the Yalong River and promote the integrated consumption of new energy in the central part of Ganzi Prefecture. Zhang Dongming said that the power station can also significantly improve the power supply structure and transmission quality of the transmission channel, reduce the cost of transmission, and help the safe and stable operation of the power grid. Through the integrated development of water, wind, solar and storage, the power station can adjust about 7 million kilowatts of randomly fluctuating wind power and photovoltaic power into a smooth, stable and high-quality power supply.
Previously, we mainly carried out the construction of auxiliary caverns in the early stage such as the incoming traffic tunnel and the air inlet tunnel of the plant, and the total length of the maintenance tunnel of the power station is 2655 meters, the excavation support has been completed. Zhang Dongming introduced that after the Spring Festival, the power station entered the accelerated stage of construction.
At the same time, at the construction site of the Sichuan-Chongqing UHV AC project (Aba to Chengdu East 1000 kV AC project), which started this year, workers are transporting construction materials to the site. With a total investment of 14.5 billion yuan, the project will help deliver clean energy from the Aba area to the Chengdu-Chongqing Economic Circle. The project is expected to be completed and put into operation in 2025, and will be able to deliver more than 35 billion kWh of clean electricity to the Chengdu-Chongqing region every year. The project leader introduced.
Since the beginning of this year, Sichuan has steadily promoted the construction of major energy projects, focusing on strengthening the energy industry and supplementing the chain. According to the data, among the 700 key projects in Sichuan Province in 2024, there are 10 new and continued energy infrastructure projects and 56 energy industry projects. In 2024, Sichuan will list a total of 700 key projects, with an estimated annual investment of 7,616400 million yuan, an increase of 545 million over 2023800 million yuan.
