Medupi Power Station

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".

History

Originally conceived as Project Alpha in 2007, with only three units to total 2400MW and cost R32 billion, the design was changed at a late stage in 2007 and doubled in size to 4764MW. Initial project cost was given as R69 billion but that was updated to approximately R80 billion later in 2007.

Power output

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.Alstom will provide the steam turbines, 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. Completion of the first two units was expected by 2012 but various delays have impacted on progress. The first 794 MW unit was commissioned and handed over to Eskom Generation on 23 August 2015. Units 5 to 1 will be completed at approximately nine-month intervals. The power station was initially expected to cost R80 billion (2007 Rands), but is now forecast to cost R154 billion.(2013 Rands)
