Name and Location
Return-to-service (RTS) projects, South Africa.

Client
Eskom.

Project Description
The projects involve the demothballing of three coal-fired stations – Camden, Grootvlei and Komati – for a combined nominal capacity of 3 800 MW.

The Camden power station, in Ermelo, Mpumalanga, is the first of Eskom’s three mothballed coal-fired power stations to be returned to service. The station will add 1 520 MW to the Eskom grid. At Camden, there are eight 200 MW units, with a combined capacity of 1 600 MW. Two generating units, with a combined capacity of 400 MW, will be brought on-stream at Camden every year from 2005 to 2008.

The Grootvlei power station, near Balfour, in Mpumalanga, has six boiler and turbine sets and a total capacity of 1 200 MW.

The Komati power station, situated between Middelburg and Bethal, in Mpumalanga, has an installed capacity of five 100 MW units and four 125 MW units. The RTS project will result in the recommissioning of two units a year between 2007 and 2011.

The three stations will each have an operating life of between 15 and 20 years.

Value
R25.1-billion.

Duration
The Camden power station was reintroduced to the grid at the end of July 2008 and officially launched by President Jacob Zuma in October 2010.

The Grootvlei power station was officially opened by President Zuma in September this year.

Latest developments
The Grootvlei power station was officially opened on September 16.

Only one unit of the Komati station remains to be completed.
