W. H. Sammis Coal Power Plant

The W. H. Sammis Coal Power Plant is a coal-fired power plant in Stratton, Ohio, USA. The plant, operated by FirstEnergy, was the subject of a Clean Air Act case by the Environmental Protection Agency filed in 1999. Current renovations and construction are being designed and managed by Bechtel Power, one of the world's largest and most successful engineering firms. Block 7 includes one of the tallest chimneys in the world (305 m), which was built in 1970. The power plant includes a tunnel for State Route 7, a four-lane freeway. The tunnel goes under the Baghouse structure, which filters particulate and toxic gases from the exhaust before entering the smoke stack.

Rockport Coal Power Plant

Rockport Coal Power Plant, located just off the new U.S. 231 Route (Now known as the Abraham Lincoln Memorial Parkway) just North of the Natcher Bridge near Rockport, Indiana, in the United States, is a 2.6-GW power plant with one of the tallest smokestacks in the world (316.4 meters).

The central smokestack and two cooling towers can be seen from as far west as Evansville, 45 miles to the west, as far north as the U.S. 231-Interstate 64 Junction, and as far east as Lewisport, Kentucky and Tell City, Indiana. It can also be seen as far south as Owensboro, Kentucky as well.

Rockport Coal Power Plant is operated by Indiana Michigan Power, a branch of American Electric Power. During the 1980s a brief public walk-through simulator was set up in an office building across the road from the plant. It allowed the public to literally walk through and see how electricity was made at this power plant at that time. A decline in visitors and overhead needed to run the office, as well as the plants change in ownership, figured well into the closing of this public service. It is now offices for the Warrick Economic Development Corporation. Two identical non-cyclonic Babcock & Wilcox units (1.3 GW each) were launched into service in December 1984 and December 1989. They are among the largest coal units built.

The coal is delivered to the plant by rail road and by barges along the Ohio River.

General James M. Gavin Coal Power Plant

General James M. Gavin Power Plant is a 2.6-Gigawatt coal-fired power station in Cheshire, Ohio, USA operated by American Electric Power. Named after James M. Gavin, it is the largest coal fired power facility in Ohio, and one of the largest in the nation. Its two units, rated at 1300 MWe each, were launched into service in 1974 and 1975. The plant is located at 38°56′09″N 82°07′00″W / 38.93583°N 82.1166667°W / 38.93583; -82.1166667, just 2.5 km (1.6 mi) upstream along the Ohio River from a smaller, older coal-fired Kyger Creek Power Plant.

Cumberland Coal Power Plant

Cumberland Coal Power Plant is a 2.6-GW pulverized coal-powered power station located in Cumberland City, Tennessee, USA, on the south bank of Lake Barkley on the Cumberland River. Owned and operated by Tennessee Valley Authority (TVA), it produces the most electricity of all plants in the TVA system.

Cumberland Coal Power Plant has one of the tallest chimneys in the world (305 m), built in 1970. Its identical Units 1 and 2, rated at 1.3 GW each, were launched into service in March and November, 1973. In 2004, the two units accounted for almost 12% of TVA's total electricity generation. Bituminous coal is delivered by barges along the Cumberland River waterway.

The Cumberland Coal Power Plant consumes about 20,000 tons of coal a day. All of the waste heat is dumped into Cumberland River water. To reduce sulfur dioxide (SO2) emissions, both units at Cumberland use wet limestone scrubbers. To reduce nitrogen oxides (NOx), the units use low-NOx burners as well as selective catalytic reduction systems, which were completed in 2004.

Ligang Coal Power Station

The Ligang power coal station is a Coal fired power station, total of 2,700 megawatts (MW) generating capacity which is located in Wuxi, Jiangsu Province, China. The coal power plant comprises 2 x 350MW units, 2 x 370MW units and 2 x 630MW units.

Eraring Coal Power Station

Eraring Coal Power Station is one of two coal fired electricity power stations on the shores of Lake Macquarie. Eraring is located on the western shore of the lake, near the township of Dora Creek. It has four steam driven Toshiba turbo-alternators, with a total capacity of 2,640 MW (660MW each).

The first turbo-alternator was brought online in 1982, with the second and third in 1983, and the fourth in 1984. There are plans to upgrade generating capacity of each of the four turbines.

The process of upgrading the control room to a fully digital system was completed in 2005.

Eraring Coal Power Station uses salt water from Lake Macquarie for cooling. This is supplied through a concrete tunnel which passes under Dora Creek and up to the station via open canal. Reclaimed sewage water from the Dora Creek Waste Water Treatment Works is heavily purified is used to generate steam for the turbines as opposed to the salt water supplies. The salt water helps in the cooling of the superheated steam as well as moderation of the temperature of outlet water to minimise thermal pollution.

The coal for Eraring Coal Power Station comes from five mines in the local area, delivered by conveyor, rail and private road. There is significant coal storage capacity on site. Eraring Coal Power Station employs the Fabric Filter system of dust collection, in which particulate emissions resulting from coal combustion are captured as opposed to being released into the atmosphere. Some of this material is stored in an area nearby while some is taken and used as a component of road base.

Electricity generated at the station is transmitted through high voltage transmission lines. Turbines 1 and 2 are connected to a 330kV transmission line while turbines 3 and 4 are connected to a 500kV transmission line.

Bayswater Coal Power Plant

Bayswater Coal Power Plant is located 16 kilometres (10 mi) from Muswellbrook, and 28 km (17 mi) from Singleton in the Hunter Region of New South Wales, Australia. Bayswater Coal Power Plant shares the title of being Australia's largest power station with Eraring Power Station. It is coal powered with four steam driven turbo alternators with a combined generating capacity of 2,640MW (4 x 660MW). Much of the coal is supplied by overland conveyors from mines it shares with the nearby Liddell Power Station.

Bayswater Coal Power Plant draws its cooling water from the Hunter River under water entitlements negotiated with the government of New South Wales. The Barnard River Scheme also allows Bayswater and Liddell to transfer water from the upper Manning River catchment into the Hunter River for their use.

The four generating units were completed progressively over 1985 and 1986.

Carbon Monitoring for Action estimates this power station emits 19.80 million tonnes of greenhouse gases each year as a result of burning coal. The Australian Government has announced the introduction of a Carbon Pollution Reduction Scheme commencing in 2010 to help combat climate change. It is expected to impact on emissions from power stations. The National Pollutant Inventory provides details of other pollutant emissions, but, as at 23 November 2008, not CO2.
