What is the reason for the power shortage in Sichuan, a major hydropower province? What are the hydropower stations in Sichuan?

Data show that Sichuan’s hydropower installed capacity has exceeded 90 million kilowatt hours this year, making it the country’s largest hydropower province. However, Sichuan, a major hydropower province, is short of power this year. So what is the reason? Let’s find out together.

What is the reason for the power shortage in Sichuan, a major hydropower province?

1. Extreme high temperature weather

Since July, Sichuan Province has encountered extremely high temperature weather that is rare in 60 years. The electricity load has reached new highs six times in a row, and the maximum electricity consumption can reach 5910 kWh, the power supply is under tremendous pressure.

In the face of tight power supply, orderly power outages were carried out.

2. The task of transmitting electricity from the west to the east

In addition to the continued high temperature weather, Sichuan has to undertake the task of "transmitting electricity from the west to the east".

As the national hydropower base, Sichuan does not have enough electricity in summer, but it still transmits part of the electricity to the eastern provinces.

3. Insufficient water supply

In July, 40% of Sichuan’s hydropower supply was dry. Since August, 50% of Sichuan’s hydropower supply was dry, resulting in a significant decline in Sichuan’s daily hydropower generation. , resulting in a significant decline in the power supply support capacity of hydropower, while Sichuan's thermal power installed capacity is relatively small, and coupled with the shortage of coal, thermal power support is insufficient, resulting in power shortages.

What are the hydropower stations in Sichuan?

1. Jinping Hydropower Station Dam

The Jinping I Hydropower Station Dam is a concrete double-curved arch dam with a height of 305 meters. It is the tallest double-curved arch in the world. dam.

The total installed capacity of the power station is 3.6 million kilowatts, with an average annual power generation of 16.62 billion kilowatt hours.

2. Xiangjiaba Hydropower Station Dam

The Xiangjiaba Hydropower Station dam is a concrete gravity dam with a maximum height of 162 meters and a total installed capacity of 7.75 million kilowatts. The main stream is the only comprehensive hub project with multi-functions such as super-large farmland irrigation and navigation through dams.

3. Lianghekou Hydropower Station

Lianghekou Hydropower Station is also called Yalong River Lianghekou Hydropower Station. It is located on the main stream of Yalong River in Yajiang County, Zizhou, Sichuan. Lianghekou Hydropower Station is a Tibetan area in China. The largest comprehensive hydropower project, the earth-rock dam of Lianghekou Hydropower Station is 295 meters high, which is very high.

4. Baihetan Hydropower Station

Baihetan Hydropower Station is located in the Jinsha River Canyon at the junction of Ningnan County, Liangshan County, Sichuan Province and Qiaojia County, Yunnan Province. The upstream is connected to the Wudongde Cascade Hydropower Station. The downstream tailwater is connected to the Xiluodu cascade power station, with a total installed capacity of 12.5 million KW and an annual power generation of 55 billion KW.h.
