 RTS Project:

Due to a sharp increase in the demand for electricity, the Eskom Board of Directors took a final decision in 2003 for the Return to Service (RTS) of the three power stations, Camden, Grootvlei and Komati, that were mothballed in the late 1980’s and early 1990’s.

The Kusile project will include a power station precinct, power station buildings, administrative buildings (control buildings and buildings for medical and security purposes), roads and a high-voltage yard.

Lethabo power station

Technical details:

• Installed capacity: 6 x 618MW
• Zero-Liquid-Effluent-Discharge type. The whole station is a closed system and no water from our processes are allowed to leave the power station premises

• Power is produced at 20kV and at 13.5kA and sent to a step-up transformer where the voltage is increased to 275kV for efficient transmission.

History:

Construction of Lethabo started in 1980. Extensive environmental studies were conducted in accordance with Eskom’s Environmental policy. It was established that the rehabilitation programmes implemented as part of Eskom’s normal operations would contribute considerably to the restoration and revaluation of the whole area.
