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 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. ...

In the western US, wetrecirculating systems are predominant. Drycooling systems use air instead of water to cool the steam exiting a turbine. Drycooled systems use no water and can decrease total power plant water consumption by more than 90 percent. [2] The tradeoffs to these water savings are higher costs and lower efficiencies.
