Progress at Kusile and Medupi

21 May 2017



Unit 1 of the Kusile coal fired power station achieved full load on 10 March 2017, following initial synchronisation on 26 December 2016. At the time of writing Kusile 1 was reported to be in the final stages of combustion optimisation prior to commercial operation. The station will eventually consist of six 800 MW units, making it one of the world’s largest coal fired power plants.

Situated near eMalahleni in Mpumalanga, Kusile – the isiNdebele and siSwati word meaning “the dawn has come” – is, Eskom says, South Africa’s largest construction project.

It is also the first power station in South Africa to be equipped with wet flue gas desulphurisation technology.

Meanwhile, Eskom has commissioned a second 500 MVA transformer at the newly built Ngwedi substation, bringing the total transformer capacity there to 1000 MVA, following commissioning of the first transformer in December 2016. The new substation marks a significant step towards completion of the Medupi Power Station Integration Project, says Eskom.
