A dry cooled system was also intended to use less water than other coalfired power stations in the fleet. [citation needed] [4] Initial project costing was estimated at R69 billion [5] but that was updated to approximately R80 billion by 2007. [6] [7] Parsons Brinckerhoff was appointed as the project engineer to oversee all construction. [8]

The power station uses a drycooling technique which reduces the amount of water used by the plant. All water used is recycled for reuse by the plant, Eskom claims. On paper, Medupi is a marvellous plant. Although it is a very large coalfired power station it has been designed to have a minimal impact on the environmental and ambient air quality.

Dry cooling systems tend to be more economical for natural gas combinedcycle plants because the amount of cooling needed is much less per megawatthour than for coal or nuclear plants. More than 15% of operating generating capacity from natural gas combinedcycle plants in the United States use dry cooling technology.

A coalfired power station is a type of fossil fuel power station. The coal is usually pulverized and then burned in a pulverized coalfired boiler. The furnace heat converts boiler water to steam, which is then used to spin turbines that turn generators.

Wet cooling towers (WCT) are widely used to reject the unutilized heat in coal thermal power plants (TPPs). But this comes at the cost of excessive water consumption. Adoption of aircooled condensers (ACC), also known as dry cooling systems, in all proposed Indian TPPs would reduce their water consumption by 26% in 2030. However, power producers are reluctant to install ACC due to technical ...
