Matimba Power Station

Location: Close to Ellisras in the Northern Province

The construction of Matimba started in 1981. Over the years Eskom has become a world respected electricity supplier and distributor. Not least of Eskom's achievements is the Power Station Matimba in Lephalale in South Africa's Limpopo Province. Designed to generate 4,000MW, Matimba - the Tsonga word for "Power" - is the largest direct dry-cooled Power Station in the world, with six 665MW turbo-generator units. The adjacent Grootegeluk colliery has sufficient coal reserves to guarantee Matimba a minimum lifespan of 35 years, extending to a possible 50 years at 2100 - 2130 tons of coal per hour. The annual send-out power from Matimba amounts to approximately 24,000GWh. Matimba is the holder of the world record of 80 days for six units on load.
