Taum Sauk Hydroelectric Power Station
Taum Sauk收抽水蓄能電站
The Taum Sauk pumped storage plant is in the St. Francois mountain region of
the Missouri Ozarks about 90 miles (140 km) south of St. Louis near Lesterville,
Missouri, in Reynolds County. It is operated by the AmerenUE electric company.
The pumped-storage hydroelectric plant was built to help meet peak power
demands during the day. Electrical generators are turned by water flowing from
a reservoir on top of Proffit Mountain into a lower reservoir on the East Fork of the Black River.
At night, excess electricity on the power grid is used to pump water back to the mountaintop.
該Taum Sauk抽水蓄能電站是在諾茲郡,密蘇里州,
距離密蘇里州奧沙克90英里(140公里)的南部紹路易斯附近萊斯特維爾的聖弗朗索瓦山區。
它是由AmerenUE電力公司經營。
抽水蓄能電站的建立是為了滿足白天峰值功率需求。

The Taum Sauk plant was among the largest of its kind when construction began in 1960.
It went into operation in 1963 with two reversible pump-turbine
units that could each generate 175 megawatts (235,000 hp) of power.
In 1999, the plant was upgraded with units capable of 225 megawatts (302,000 hp) apiece.
On December 14, 2005, a catastrophic failure in the upper reservoir dam
put the plant out of operation until it was rebuilt, recertified, and reopened on
April 21, 2010. The new upper reservoir dam, rebuilt from the ground up,
is the largest roller-compacted concrete dam in North America
The plant was named an IEEE Milestone in October 2005, just months before the Upper Reservoir failed.
該Taum Sauk工廠是同類施工中規模最大的,施工開始於1960年,
投資於1963年的兩個可逆式水泵水輪機的單位,
每個發電可以在175兆瓦(235,000馬力)。1999年,
該廠進行升級了每個單位225兆瓦(302,000馬力)的能力。
2005年12月14日,在水庫大壩上出現災難性故障時工廠停止了運行,
直到重建,重新認證,並在2010年4月21日重新開放。
