Matla Power Station

Location: Approximately 30km from Secunda in Mpumalanga

Matla, which means strength or power in SeSotho, is a coal-fired power station, situated near Kriel on the Mpumalanga highveld, approximately 200km from Johannesburg. It is a base-load plant, which means it operates continuously, except for regular scheduled stoppages for inspection and maintenance on the individual units.
Matla consists of six 600MW units at an installed capacity of 3 600MW, the first of the
giant 3600MW coal-fired power station to be commissioned in the 1980’s. Average
availability over the last 3 years is at 93.84%. There's approximately 718 employees
(excluding students and contractors) at this station. Matla is one of a few power
stations in the world with a concrete boiler house superstructure, giving it an outward
appearance very different from other power stations in South Africa. The use of
concrete reduced the construction lead time and capital costs at a time when there was
a worldwide shortage of steel. The planning and design of Matla Power station
commenced in the early 1970s. It was designed for an operating life of 30 years, but its
lifespan has since been extended to 60 years. Construction started late 1974, and the
first of the 600MW sets started feeding power into the national grid towards the end of
1979. Matla reached full operational capacity in early July, 1983.
