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.

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]

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.

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.

Product Description. Medupi, rising from the dry Limpopo Province bush veld, was the first baseload project built in South Africa in 20 years. It would be the largest drycooled coalfired power station in the world and was developed by Eskom, which generated 90 per cent of Southern Africa's power, at an estimated cost of R125 billion. In spite ...

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.
