Medupi Power Station is a dry-cooled coal-fired power station being built by Eskom near Lephalale in Limpopo province, South Africa. According to Eskom, the name chosen for the station, Medupi, is a Sepedi word for "rain that soaks parched lands".[1]

Power Output[edit]

When completed, the power station is to have six boilers each powering an 800 MW turbine, producing 4800 MW of power. It is expected to become the largest dry-cooled coal-fired power station in the world.[2] Alstom will provide the steam turbines,[3] Medupi will be supplied by coal from Exxaro's Grootegeluk coal mine, located north of the site. Eskom has placed a contract with Exxaro to supply 14.6 MT of coal per year for 40 years.[4] The first 800 MW unit is expected to be commissioned in the middle of 2015, with the next units following at nine-month intervals. The power station was initially expected to cost R32 billion, but is now forecasted at R300 billion.[5]

Power Generation[edit]

On 18 February 2015 the Public Enterprises minister, Lynne Brown, announced that the number 6 turbine is running at the optimum speed of 3000 revolutions per minute.[6] Official news reports stated that the turbine will add 794 megawatts to the national grid.[7]

Critics[edit]

The building of the coal power station has attracted criticism.[8] Critics have alleged that the government pushed the project forward because the African National Congress held a 25% share of the venture and stood to make a profit of close to 1 billion rand on the deal.[9][10] Backers of the project argued that the plant is needed.[11] Some critics say that effective management of coal supplies was needed, not another coal station.[12]

The African Development Bank lent $500 million for the project in 2008. In 2010, the World Bank agreed to lend South Africa $3.75 billion to assist with several energy projects, with $3.05 billion allocated for completion of the Medupi power station. The approval of the World Bank loan drew criticism for supporting increased global emissions of greenhouse gases.[13]
