9.2 billion! Zhejiang Jingning pumped storage power station project starts construction

Release time：2024-09-02click：0

Recently, according to news from China Power Construction Group (hereinafter referred to as "PowerChina"), on November 2, 2022, the Zhejiang Jingning pumped storage power station project in which East China Research Institute, a subsidiary of China Power Construction, participated in the investment and controlled, officially started construction.

This project is the first batch of pumped storage power stations approved in Zhejiang Province in 2022. The project has a total installed capacity of 1,400MW, a total investment of 9.2 billion yuan, and a designed annual power generation of 1.4 billion KWh.

It is expected that after the project is connected to the grid, it will help Zhejiang Province’s power grid to perform functions such as peak shaving and valley filling, energy storage, peak and frequency regulation, and at the same time promote local economic development and employment.

Pumped hydro storage continues to be popular

In recent years, due to various factors such as the epidemic, extreme weather, and dual carbon target policies, the Due to the compound impact, energy storage has developed rapidly, among which pumped hydro storage has always been firmly in the lead.

According to statistics from relevant institutions, as of the end of 2021, in terms of power energy storage projects, the cumulative installed capacity of projects in operation worldwide was 209.4GW, a year-on-year increase of 9%. Pumped hydro storage, as always, accounts for the largest share, at 86.2%.

The cumulative installed capacity of China’s put-in-operation projects accounts for more than 20% of the world’s total, at 46.1GW. Pumped hydro energy storage accounts for 86.3%, and the cumulative installed capacity is 39.8GW.

By the end of August 2022, my country’s pumped hydro storage installed capacity will be 16,700MW, with an investment amount exceeding 110 billion yuan.

Such a huge installed capacity and investment amount are enough to illustrate the popularity of the pumped hydro energy storage market in recent years, and judging from the current momentum, pumped hydro energy storage has not slowed down the pace of expansion at all. sign.

Pumped hydro energy storage project status

Since September 2022, the development of pumped hydro energy storage in my country Still heating up.

According to incomplete statistics on energy storage from Veike.com, since September 2022, at least 9 pumped storage power station projects have started construction in my country.

< div> From the above table, you canIt is known that in the past two months, the total installed capacity of pumped hydro energy storage projects has exceeded 12,600MW, and the total investment amount has exceeded 87.2 billion yuan, mainly distributed in six provinces: Zhejiang, Gansu, Shanxi, Hunan, Guangdong, and Liaoning.

Since September, the installed capacity of pumped storage power station projects in Zhejiang Province ranks first among the six provinces, and the investment amount of pumped storage power stations in Gansu Province ranks the highest among the six provinces.

Among them, the two projects in Zhejiang have a total installed capacity of 3800MW and a total investment amount of 23.2 billion yuan; the two projects in Gansu have a total installed capacity of 2800MW and a total investment amount of 26 billion yuan; and the two projects in Shanxi The total installed capacity is 2,600MW, and the total investment amount is 18.3 billion yuan; Hunan, Guangdong, and Liaoning are all one project.

In addition, the nine pumped storage power station projects under construction have an installed capacity of more than 1,000MW, including a total of 7 projects with an installed capacity of 1,200MW and 1,400MW, accounting for a huge proportion.

It illustrates from the side the huge advantage of pumped hydropower storage in energy storage.

In terms of project investment amount, the average investment amount per project is approximately 9.7 billion yuan.

The lowest investment is the second phase project of Meizhou Pumped Storage Power Station in Guangdong, with an investment amount of 4.7 billion yuan; the largest investment is the preparatory project of Jiande Pumped Storage Power Station in Zhejiang, with an investment amount of 140 billion.
