Cayuga Generating Station is an electricity-generating facility, located in Eugene Township, Vermillion County, near Cayuga, Indiana. Its almost identical, coal-fired Units 1 and 2 were launched into service in 1970 and 1972, and have a combined name-plate generating capacity of 1,062 MWe. Unit 4 (121 MWe, launched in 1993) is powered by natural gas, but can also be switched to oil. [1] There are also four minor oil-fired units (numbered 31–34, 2.6 MWe each) of internal combustion design. The facility is entirely owned by Duke Energy. [2]
In 2006, the plant emitted 86,174 tons of sulfur dioxide (SO2) into the air. Its SO2 emission rate per unit of electricity produced was 26.68 lb/MWh in 2006, ranking 2nd worst in the United States. In 2008, Cayuga Station's flue-gas desulfurization (FGD) for Units 1 and 2 went online reducing the station's SO2 emissions by approximately 95%. [3]

Coal generated about 19.5% of the electricity at utility-scale facilities in the United States in 2022, down from 38.6% in 2014 and 51% in 2001. In 2021, coal supplied 9.5 quadrillion British thermal units (2,800 TWh) of primary energy to electric power plants, which made up 90% of coal's contribution to U.S. energy supply. Utilities buy more than 90% of the coal consumed in the United States. There were over 200 coal powered units across the United States in 2022. Coal plants have been closing since the 2010s due to cheaper and cleaner natural gas and renewables. Due to measures such as scrubbers air pollution from the plants kills far fewer people nowadays, but deaths in 2020 from PM 2.5 have been estimated at 1600. Environmentalists say that political action is needed to close them faster, to also reduce greenhouse gas emissions by the United States and better limit climate change.

The A. B. Brown Generating Station is a four-unit, 700 megawatt (MW) power plant, located on the northern bank of Ohio River, 8 miles (10 km) east of Mount Vernon, Indiana and 5 miles (8 km) southwest of Evansville, Indiana just west of the Posey-Vanderburgh County Line. Each of the two coal-fired units has a name-plate capacity of 265.2 MW. Bituminous coal is used as a primary fuel type, which can be substituted for natural gas. There are also two gas turbine units, 88.2 MW of nameplate capacity each. The facility is owned by Centerpoint Energy. Vectren announced a plan to retire the plant in 2023 and replace it with a natural gas power plant; however, this plan needs to be approved by the Indiana Utility Regulatory Commission.
Petersburg Generating Station is a major coal-fired power plant in Indiana, rated at 2.146-GW nameplate capacity. It is located on the White River near Petersburg in Pike County, Indiana, just 1 mile (1.6 km) upstream from a much smaller coal-fired Frank E. Ratts Generating Station. Petersburg G.S. is owned and operated by AES Indiana.
AES Barbers Point Plant was a medium-size coal-fired electrical power station located in the south-west corner of the Hawaiian island of Oahu. Owned and operated by AES, the plant was the only coal-fired power plant in the state of Hawaii and was the state's leading single source of toxic pollutants. AES Barbers Point Power Plant consisted of a single unit on the grounds of Campbell Industrial Park, had a year-around capacity of 180 MWe, and in 2006 represented about 11% of Oahu's commercial electricity supply.

Coal gasification is a process whereby a hydrocarbon feedstock (coal) is converted into gaseous components by applying heat under pressure in the presence of steam. Rather than burning, most of the carbon-containing feedstock is broken apart by chemical reactions that produce "syngas." Syngas is primarily hydrogen and carbon monoxide, but the exact composition can vary. In Integrated Gasification Combined Cycle (IGCC) systems, the syngas is cleaned and burned as fuel in a combustion turbine which then drives an electric generator. Exhaust heat from the combustion turbine is recovered and used to create steam for a steam turbine-generator. The use of these two types of turbines in combination is one reason why gasification-based power systems can achieve high power generation efficiencies. Currently, commercially available gasification-based systems can operate at around 40% efficiencies. Syngas, however, emits more greenhouse gases than natural gas, and almost twice as much carbon as a coal plant. Coal gasification is also water-intensive.
