Why is Sichuan, hydropower provinces Sichuan?

Affected by the continuous high temperature and drought disaster weather, Sichuan Power Grid faces an extremely severe confession situation and has different degrees of electricity limit. Why is Sichuan, a large hydropower province, how can it be inferior?

Multiple reservoirs are approaching dead water levels, and hydropower is reduced by 50%

The current water level of Tingzikou Hydropower Station is 438.78 meters, and the dead water level is 438 meters; the current water level of Changheba Power Station is 1652.56 meters, and the dead water level is 1650 meters. In the news, the water storage of the reservoir almost disappeared to the dead water level. In this round of high temperature weather, in addition to the continuous breakthrough of the temperature, the precipitation is also the least in history. The rivers are seriously withered, resulting in a rare phenomenon of "anti -dead period" in the reservoir library.

According to Ma Yuanjiang, director of the production and technical department of the State Grid Sichuan Yingxiu Bay Power Plant, this year, the water of the Minjiang River Basin and Yuzi Creek continued to dry. Compared with the same period of the same period, the water from the water was nearly 40 %. The normal operating water level of the Ziping Panel Reservoir is 850 meters per year. At present, the operating water level of the reservoir drops to 829 meters. It is the lowest water level since the completion of the reservoir in 2006. The current water level of the Dadu River Waterfall Ditch Hydropower Station is currently 812 meters, which is about 30 meters from the past. It is the lowest water level since the construction of the waterfall ditch.

And hydropower requires a high enough water to form a gap to drive the water turbine to rotate. Affected by the continuous decline in the reservoir's water storage, the daily power generation of Sichuan hydropower has dropped sharply, and the number of natural water and electricity has decreased from about 900 million kilowatt -hours to about 450 million kilowatt -hours, and the decrease has reached 50%. The speed continues to decline. Sichuan is a large hydropower province, and the proportion of hydropower installed capacity has reached about 80%. Due to the decline in hydropower power generation capacity, the province's power supply support capacity has fallen sharply.

While the supply has dropped sharply, the demand for electricity caused by high temperatures has surged. At high temperatures, everyone has turned on the air conditioner to "renew", resulting in the high cooling load. Taking Chengdu as an example, the electricity load during the peak period has accounted for 40%of the power load in Chengdu.

From the "scarcity" of electricity during the peak, to the "double lack" of power and electricity throughout the day

In recent years, during the summer of Sichuan Power Grid, during the peak of the summer, there will be a peak periodic period of electricity. Similar to congestion during the peak travel during holidays, the power grid is like a highway. At the same time, everyone uses electricity and will also have congestion. Therefore, the power department advocates everyone to take the initiative to avoid the peaks, use the peak period of electricity during the day, and try to move the electricity during the night trough.

However, the recent high temperature, the avoidance peak has begun to work completely. Because the growth of electricity load is mainly the load of the air conditioner, the continuous high temperature allows each air conditioner to run the axis for 24 hours without stopping. Chuanguan News reporters have learned that at present, the province's power supply and demand situation has been "scarce" in the peak period in July to the severe situation of "double lack" of power and electricity throughout the day. Increased by 25%at the same time.

If the power load is high for a long time, the power grid continues to withstand overload and heavy load pressure, which may cause the power grid safety accident and cause a large -scale power outage. Therefore, in order to ensure the security of the power grid, we have to take power supply control measures.

Zhou Jian, deputy chief engineer of the Electric Power Schedule and Control Center of State Grid Sichuan Province, introduced that the capacity of hydropower power generation has continued to decline, and the supply and demand gap continues to expand. This situation is unprecedented. Our province has initiated three -level power supply control measures to ensure people's livelihood electricity, and propose enterprises to actively expand the peak avoidance of electricity. From August 14th to 20th, some high -load energy enterprises within the province will implement the suspension of production to allow the electricity to live in the people. Emergency regulation, let the load use the power load about 7 million kilowatts. At the same time, more than 4,000 enterprises in the province responded to active avoidance operations. They may arrange production in the low -temperature period in the middle of the night, or start high -temperature leave to allow electricity to people.

Sichuan not only delivered water and electricity, but also purchased electricity from outer provinces

In order to make every effort to ensure the demand for people's livelihood and increase the power supply, in the case of a sharp decrease in hydropower, Sichuan increased the power generation plan of other power supply, photovoltaic, and wind power to ensure the maximum utilization of power generation resources. In order to ensure the supply of electrical coal, Sichuan government -enterprise coordinated promotion of thermal power depository coal. As of August 13, the entire network coal deposit was 2.15 million tons, an increase of 1.45 million tons year -on -year, and the increase was more than double, ensuring that thermal power was full.

In fact, Sichuan not only delivered water and electricity, but also purchased electricity from other provinces. At present, localities have also increased the power support for Sichuan. On August 16, the State Grid Corporation stated that it will play a role in the allocation of large power grid resources, organize cross -regional inter -provincial lack of mutual benefit, and maximize support for power supply in Sichuan and Chongqing. At present, all the surplus electricity in the northeast, North China, and Northwest China is transported to East China, Central China, Southwest and other places. Sichuan has implemented cross -provincial and cross -regional support for Sichuan's maximum transmission channel capabilities. All power enters Sichuan support channels. At the same time, the scale of water and electricity stayed in Sichuan, and greatly reduced the power of the annual delivery plan of the Sichuan trough.

At present, more than 25,000 power repair personnel are on standby for 24 hours. 940 party member service teams, party members' assault teams, and more than 18,000 party members fight for the front line of electricity. For the residential communities that have exceeded the loading of the distribution network equipment, they also prepare for a train and UPS emergency power supply.

Under extreme high temperature, every electricity is not easy. The power department advocates that the whole society saves electricity, scientific electricity, and low -carbon life.

Hot Tips >> Netizens: What channels can I check the authoritative power outage pre -notification information through?

If it is a planned power outage information, you can query through the national power grid customer service telephone 95598 or the Palm Sichuan Electric APP; if it is a failure power outage information, there is no way to notify the notice, and the power outage notification information will be updated in a timely manner after the failure;The power outage will be performed according to the emergency plan formulated by the relevant departments.

Netizen: Now that the power is so tense, you should save electricity. Can you turn off the city's useless outdoor advertising lights and large screens?

Sichuan recently held the power guarantee dispatch meeting of electricity, and there are non -necessary electricity needs such as landscape lighting and light shows in various places.The Great World of Zigong Zhonghua Lantern has also been suspended, and it is actively responding to the power saving initiative with actual actions to make electricity in the people.
