Settled the "hard task" of 20 -seater in the province's 20 -seater control hydropower stations to do a good job of water storage and confession

Cover reporter Chai Fengmu

On September 21, the cover reporter learned from the Sichuan Provincial Department of Water Resources that due to the continuous high temperature and rainstorm, as of September 20, the 20 -seater controlling hydropower station returned to 6.6 billion cubic meters of water storage, and only 51% of the water storage task was completed. There are still 6.4 billion cubic meters of water storage gap. In order to ensure the stable and safe supply of electricity and water consumption this winter, the Sichuan Flood Control and Drought Resistance Headquarters organized a special video conference on water storage for controlling water power stations in the province to make a good job of water storage and confession.

The water storage capacity is 6.4 billion cubic meters

The situation of power protection is very severe

The reporter learned from the meeting that as of September 20, the 20 -seater controlling water power stations in Sichuan returned 6.6 billion cubic meters to complete 51%of the water storage task. The eight -seater controlling hydropower stations in the plains and its surrounding areas needed a water storage capacity of 4 billion cubic meters, nearly 40%more than the same period of the same period. At the same time, it is expected that from late September to November, the main rivers in Sichuan Province will still be small, and the situation of water storage and protection this year is not optimistic.

According to estimates, if the electricity growth rate is 10%(the average growth rate in the past 4 years), Sichuan this winter and spring dry period (December 2022 to April 2023) will reach 127 billion kilowatt -hours of electricity. It will increase by 11.6 billion kilowatt -hours year -on -year.

On the one hand, the amount of water is small, but on the other hand, the electricity consumption increases greatly. According to the calculation of the information department, if you consider insufficient water, insufficient water storage of the reservoir, insufficient gas gas gas, and difficulty in the protection of Sichuan electricity and external purchase volume, it is difficult to ensure that the supply of electricity in Sichuan may appear 10%-30%of the gaps. The situation of electricity for winter power is very severe.

Deepen the "big water tone" mechanism

The Water Conservancy Department coordinates the work of water storage for water storage

Since late August, through scientific storage and refined scheduling, the water level of the Ziping Panel Reservoir has risen slowly. The picture shows the water storage of the Zipingpu Reservoir in early September. Photo confession of Zipingpu Reservoir dispatching center.

As the competent authority and leading unit of water resource scheduling in the province, the Sichuan Water Resources Department formulated a "one library and one policy" water storage plan for the organizational control water power station management unit in mid -August. In the case, detailed the implementation of water storage timing, tasks, progress and guarantee measures. The 13 billion cubic meters of water storage mission of the 20 -seater controlling hydropower reservoir in the province decomposed it in 7 stages in the ten stages, and the water storage target was clearly storage targets in the middle of the day, and the "one -library, one plan, one library and one strategy".

In addition to the water conservancy department, water storage guarantee also involves multiple industries and competent departments. Guo Hengxiao said that by deepening the use of the "large water tone" mechanism, it has strengthened the interoperability of cross -unit information such as water conservancy, scriptures, meteorology, State Grid Sichuan company, and hydropower management units, and coordinated the establishment of a "coal, electric oil and gas water" dispatch mechanism; at the same time, power generation enterprises It is necessary to adhere to the principle of "electrical and water -tone" in accordance with laws and regulations, resolutely implement the water storage plan, scientifically arrange the order of power generation, and leave room for controlling water storage water storage.

In the next step, the Sichuan Provincial Department of Water Conservancy will continue to strengthen the tracking and inspection, inform the unit with poor scheduling instructions and water storage plans in a timely manner, and go all out to complete the target tasks of water storage and confession.
