A 1000 MW dry cooled coalfired power station would typically require around GL of water per year. While dry cooling reduces water consumption to around 2 GL/year (from around 17 GL/year), it also reduces sentout efficiency, which leads to higher fuel requirements and higher emissions of carbon dioxide and other greenhouse gases. ...
plant uses a dry cooling tower, the other is wet. The result shows that, for a 2x600MW power plant operating 5500 hours in a year, the wet cooling plant uses 145200 tonnes less coal than the dry cooling plant. Table 2.

The turbines at coal fired power stations are steam driven. The steam is produced using highly purified water demineralised water. This water needs to be recovered due to the high costs involved in its production and also to save water. When the spent steam leaves the turbine it is at a very low pressure and high volume.
Based on regional averages, retrofitting dry cooling systems in lieu of wet cooling towers decreases total annual plant water consumption at existing coal and gasfired power plants by 93% and , respectively, while increasing the levelized cost of electricity generation by approximately 12% and 18%, respectively.

Kendal has an indirect drycooling system, which means that it uses significantly less water in its cooling processes than the conventional wet cooled power stations. The station's cooling towers are the largest structures of their kind in the world with a height and base diameter of 165m. ... Only coal fired power station in the country that ...
Eskom in South Africa quotes drycooled plants as having total station water consumption under litres/kWh, this being for steam cycle losses (cf about L/kWh for wetcooled plants). Eskom is building two of the largest coalfired plants in the world each 6 x 800 MWe and one of these will be the largest drycooled plant in the world.

Coalfired plant will add to Indian grid by August Singapore relies on fossil fuels more than any other country " study. The Medupi Power Station uses direct drycooling systems due to the water scarcity in the Lephalale area and is the fourthlargest coalfired plant and the largest drycooled power station in the world.
Three major options are available: oncethrough, wetrecirculating, and dry cooling. About 53 percent of coal plants in the United States use oncethrough cooling, about 40 percent use wetrecirculating, and less than one percent use drycooling.
