So, in summary it can be said that gasification-based power offers efficiency benefits in the use of water. Raw water use in IGCC plants is lower than in pulverized coal plants. Without CCS, PC plants have a much higher steam turbine output, requiring more cooling water and condenser duties (typical raw water use ratio of 1.7:1.0).

The typical US home uses about 7,200 kilowatt-hours of electricity each year [1]. Megawatts are used to measure the output of a power plant or the amount of electricity required by an entire city. One megawatt (MW) = 1,000 kilowatts = 1,000,000 watts. For example, a typical coal plant is about 600 MW in size.

With current technology, coal-fired power plants using carbon capture equipment are an expensive source of electricity in a carbon control case. Other power sources, such as wind, nuclear, geothermal, and the natural gas combined cycle without capture technology currently appear to be more economical.

Colorado was the seventh-largest natural gas-producing state in 2020 and accounted for almost two-fifths of total U.S. coalbed methane production in 2019. Since 2010, Colorado's renewable electricity net generation has more than tripled, led by increased wind and solar, and accounted for 30% of the state's total generation in 2020.

Like nuclear production, small coal-fired plants can have a maximum capacity as low as hundreds of MW. The Kahone Thermal Power Station in Senegal, for example, has a capacity of only 102 MW. If we assume an average capacity factor of around 64%, daily output for coal can be as low as 1600 MWh per day.

Coal trader's web sites give base prices in the international market. We take a coal price of around 65 $ / Ton. The cost of coal consumed by 100 MW power plant is (53.8 x 65) 3497 $ /hr. A 100 MW unit produces 100,000 units of electricity. So the cost of coal per unit of electricity is (3497/100,000) 3.5 cents per unit.

By the 1990s coal use became the norm. Typically coal preparation involves drying and grinding coal to tiny particles of less than 1mm for injection. The coal particles are separated from released gases in a cyclone. The waste gas, and sometimes natural gas, can be used for drying additional coal, which is generally kept below 6% moisture content.
