The water condition of Shimen Reservoir is good this year. Except for the adjusted release of water in response to the typhoon, the water level is almost maintained at a high level at other times.

[Reporter Li Rongping/Taoyuan Report] Shimen Reservoir has abundant rainfall throughout the year. The North District Water Resources Bureau of the Water Resources Department uses high water levels to supply water and generate electricity. According to statistics, this year’s power generation has exceeded 400 million kWh, which is the first time in the past 20 years to exceed 400 million kWh. , the implementation of the green energy and environmental protection policy will also help to increase the revenue of the treasury; in November this year, a third dredging ship will be added to pump mud, and with the dredging of upstream land dredging, it is expected that the dredging volume will reach 4.4 million cubic meters by the end of the year, exceeding The average amount of mud and sand entering the reservoir over the years is 3.42 million cubic meters, which helps to prolong the life of the reservoir and rejuvenate it.

As of 6 o'clock tonight, the water level of the Shimen Reservoir dam is 245.15 meters (245 meters full), with a water storage capacity of 206.56 million cubic meters, and a water storage rate of 100%. This year's cumulative rainfall is 2890 millimeters, the cumulative power generation is about 417 million kWh, and the dredging is 4.04 million cubic meters, which is 40,000 cubic meters ahead of the predetermined target of 4 million cubic meters.

Guo Yaocheng, deputy director of the North Water Bureau, said that the Shimen Power Plant under the jurisdiction of the North Water Bureau is located downstream of the dam site, and Taipower Corporation is entrusted to cooperate with the bureau's water supply operation to generate electricity. Except for the two devices in the plant, a total installed capacity of 90MW (megawatts) hydroelectric power generation Units can also be remotely controlled to operate Yixing units (1 unit, installation capacity 40MW). Shimen units were commissioned in 1964, with a total designed annual generating capacity of 210 million kWh; Yixing units were commissioned in 1983, with a total designed annual generating capacity of 213 million kwh .

Guo Yaocheng said that in 2004, typhoon Aere brought strong winds and heavy rains across the border and caused more serious siltation in the Shimen Reservoir. The Water Resources Department assessed that it was necessary to increase the hydraulic sand discharge capacity to prolong the life of the reservoir, and promoted the anti-silting project of the Shimen Power Plant. No. 2 The pressure steel pipe of the machine was changed to a sand discharge channel. The renovation plan was completed in 2015. The two units of Shimen Power Plant can share the original pressure steel pipe of the No. 1 unit for power generation. Prioritizing the task of stable water supply, the annual power generation has never reached 400 million kWh in 20 years.

Shimen Power Plant’s operating data over the years has exceeded 400 million degrees 10 times. There are still 31 days to generate power this year. It is estimated that the power generation capacity can be further increased. The North Water Bureau will continue to monitor the water situation, taking into account stable water supply and power generation efficiency, and is convenient Water and electricity use by the public and industry.

In addition, due to the high water level of the Shimen Reservoir, land excavation in the upper reaches is not easy, but the dredging operation in the water is not affected, and can be operated 24 hours a day. The third dredging ship for Shimen Reservoir was assembled and tested on November 2. , and now three pumping dredgers are operating in the dam area of ​​the reservoir water storage area, Dawanping and Amuping waters. The North Water Bureau is confident that the amount of dredging this year will hit a record high, allowing the reservoir capacity to continue to rejuvenate.

The water condition of Shimen Reservoir is good this year. Except for the adjusted release of water in response to the typhoon, the water level is almost maintained at a high level at other times.
