investigated and tested the use of dry cooling technology for its new coalfired power stations. Today, the total dry cooled installed capacity is 10 477 megawatts. Drycooling technology does not rely on evaporative cooling for the functioning of the main cooling systems. As a result dry cooled power stations use approximately 15 times less ...

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.

Matimba Power Station is a coalfired power plant that is located in Limpopo. The mine is operated by Eskom, and it is billed to provide 3,990 Mega Watts, which is achieved by six 665 MW units. Matimba Power Station is dry cooled, which means that it does not require so much water to cool it, and also it does not pollute the environment.

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.

Abstract The share of coal generation in the global electricity production remains stable and prevails over other primary energy sources. A decrease in the coalfired power generation in some EU countries and the United States is balanced by its stable growth in Asia (China, India, Indonesia, South Korea) and Africa (South Africa). In 2021, global coal generation increased by 9% to a new all ...

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. ...
