Bowen Coal Power Station

The Bowen Coal Power Station is a coal-fired power station located in Euharlee, United States, approximately 14 km (8.7 mi) west-south-west from Cartersville. At 3,499 megawatts, Plant Bowen has the second largest generating capacity of any coal-fired power plant in North America, and the largest in the United States; only Ontario Power Generation's Nanticoke Generating Station in Canada has more generating capacity. Plant Bowen ranked third in the nation for net generation in 2006 producing over 22,630,000 MWh. The station is connected to the southeastern power grid by numerous 500 KV transmission lines, and is owned and operated by Georgia Power, a subsidiary of Southern Company.

Bowen's four cooling towers are 116 m (381 ft) tall and 97 m (318 ft) in diameter and can cool 1,100,000 litres (290,000 US gal) per minute. Another 26,000 litres (6,900 US gal) of water is lost to evaporation which creates the distinctive white clouds rising from each tower.

Bowen's two smokestacks are 300 m (980 ft) tall. Particulates are removed from the exhaust gases through the use of electrostatic precipitators. The exhaust gases are then closely monitored to comply with air quality regulations. In addition, SCR units have recently been constructed on all four units to meet federal clean air and ozone standards.

In 2006, Bowen was the largest emitter of sulfur dioxide in the United States (at 206,442 short tons (187,281,032 kg)), and ranked 39th worst in the nation in terms of sulfur dioxide emissions per kilowatt-hour of electricity produced. All four units at Bowen are scheduled for scrubber installations. Through these efforts, such emissions will be reduced by as much as 95%. Construction began in 2005 on the first two of four scrubbers and will take three years to complete. The scrubbers at Bowen will be among the largest fiberglass vessels ever to be built in the United States. The facility is the third largest producer of carbon dioxide, after Plant Scherer and James H. Miller Jr. Power Plant, emitting 20,500,000 short tons (1.86×1010 kg) of CO2 in the atmosphere each year.

Suizhong Coal Power Station

The Suizhong Power Station is a large coal-fired power station in Suizhong, China. The facility generates power by utilizing two units at 800 MW and two units at 1,000 MW, totalling the installed capacity to 3,600 MW.

CSEC Guohua International Power Company Limited (previously known as CLP Guohua Power Company Limited) is an evergreen joint stock company formed by CLP (30%) and China Shenhua Energy (70%). It is CLP's first evergreen joint stock company in the Mainland.

Matla Coal Power Station

Matla Coal Power Station in Mpumalanga, South Africa, is a coal-fired power plant operated by Eskom.

Employees: Approximately 1100

Technical detail:

  • Six 600MW units
  • Installed capacity: 3 600MW
  • 2001 capacity: 3 450MW
  • Design efficiency at rated turbine MCR (%): 37.60%
  • Ramp rate: 25.00% per hour
  • Average availability over last 3 years: 93.84%
  • Average production over last 3 years: 25 199GWh

History: Matla Power Station was the first of the giant 3 600MW coal-fired power stations to be commissioned during the 1980's. Construction started late in 1974 and by July 1983 the station was fully operational. The station is 22 years old this year.

General: Matla is one of a few power stations in the world with a concrete boiler house superstructure, giving it an outward appearance very different from other power stations in South Africa. The use of concrete reduced the construction lead time and capital costs at a time when there was a worldwide shortage of steel.

Matla was awarded a gold award by the National Productivity Institute (NPI) in 1998.

Safety: Matla was awarded NOSCAR status by the National Occupational Safety Association (NOSA) for the 5th time in March 2001.

Duvha Coal Power Station

Duvha Coal Power Station in Mpumalanga, South Africa, is a coal-fired power plant operated by Eskom. The 300 metres (980 ft) tall chimneys at Duvha are the tallest structures in Africa.

Construction of Duvha Power Station started in November 1975 and the last unit came into operation in 1984.

In 1993 Duvha became the first power station in the world to be retrofitted with pulse jet fabric filter plants on three of its six units. These plants contribute largely to the reduction of air pollution by removing 99.99% of the fly ash which otherwise would be released into the air through the station's chimneys.

The Duvha Coal Power Station consists of six 600MW units with a total installed capacity of 3,600MW operating with a turbine Maximum Continuous Rating of 37.6%.

Tutuka Coal Power Station

Tutuka Power Station in Mpumalanga, South Africa, is a coal-fired power plant operated by Eskom.
