Medupi Power Station is a drycooled coalfired power station built by Eskom near Lephalale in Limpopo province, South Africa. The name chosen for the station, Medupi, is a Sepedi word which means "gentle rain". With an installed capacity of 4,764 MW, when fully operational it should be the 8th largest coalfired power station in the world.

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.

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 ...

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.
