The Dam Hartwell ( english Hartwell Dam ) is a dam with hydroelectric power plant in the United States . It dams the Savannah River , which at this point forms the border between Hart County , Georgia and Anderson County , South Carolina , to a reservoir (English Lake Hartwell ). The small town of Hartwell is about 10 km west of the dam.
In addition to generating electricity, the dam is also used for flood protection and drinking water supply. Its construction was approved by the US Congress through the Flood Control Act of 1950 . Construction of the dam began in October 1955. It was completed in 1959. The dam is owned by the United States Army Corps of Engineers (USACE) and is also operated by the USACE.
Barrier structure
The shut-off consists of a gravity dam of concrete with a height of 62 m (204 ft ) above the river bed and Erdschüttdämmen, which adjoin both sides. The total length of the barrier structure is 3779 m (12,400 ft); the length of the dam is 579 m (1900 ft). 672,808 m³ (880,000 cubic yards ) of concrete were used. The dam wall has a flood relief with 12 segment weirs .
Reservoir
At the normal storage target of 201 m (660 ft) above sea level , the reservoir extends over an area of around 226.2 km² (55,900 acres ). The maximum storage target at high water is 202.7 m (665 ft). The impoundment began in February 1961. The normal stagnation target of 660 ft was reached on March 12, 1962. The lowest level was on December 9, 2008 at 194.3 m (637.5 ft); the average level is 200.4 m (657.5 ft).
power plant
The power plant is located at the foot of the dam on the right side of the river. The first machine went into operation on April 27, 1962. The installed capacity with 5 Francis turbines amounts to a total of 422 MW . The average annual production is 468 million kWh . The power plant serves to cover peak loads .
Originally 4 Francis turbines with a maximum output of 66 MW each were installed; however, the arrangements for the installation of a fifth machine have already been made. The fifth turbine with a maximum output of 80 MW was then put into operation in 1985. By increasing the output of machines 1 to 4, which was carried out from 1997 to 2000, the installed output of the power plant could be increased from 344 to 422 MW. In the switchgear , the generator voltage is increased from 13.8 kV to 230 kV using power transformers.
Others
The total cost of the project is put at just over $ 89 million . Originally the cost was estimated at $ 68.4 million. The electricity generated is sold by the Southeastern Power Administration . From 1962 to September 1988, it generated revenues of more than $ 118 million. In 2001 the company had revenues of $ 14 million.
