Name and Location
Medupi power station project, Lephalale, Limpopo, South Africa.

Client
Eskom.

Project Description
Medupi, which means ‘a rain that soaks parched lands, giving economic relief’, will be a dry-cooled coal-fired, base-load power generating plant, comprising six 800 MW units, with a 4 800 MW installed capacity – the biggest of its kind with dry cooling in the world. It will be located on a 883 ha site (formerly a farm named Naauw Ontkomen), previously used for game and cattle grazing.

The planned operational life of the station is 50 years.

The power station will use high-tech supercritical boilers, which will operate at higher temperatures and pressures than older boilers, providing greater efficiency.

It is the first base-load, coal-fired station to be built in South Africa in over 20 years and its delivery on schedule is viewed as critical.

The project will form part of the utility's integrated strategic electricity plan.

Value
R91.2-billion, with Eskom having spent R55.2-billion as at March 31, 2012.

Duration
The plant will be ramped up to full capacity by 2017.

Latest Developments

Siemens is on track with its work for State-owned power utility Eskom’s Medupi and Kusile power stations, but is facing challenges, owing to delays in the civil works at both project sites.

To mitigate the impact of the civil works delays, Siemens is in constant engagement with Eskom to monitor the progress of the civil works contractors.

The company’s scope of work involves the design, manufacture, shipping, installation and commissioning of seven 910 MVA generator transformers at Medupi and 29 auxiliary transformers.

Siemens project manager for the Kusile and Medupi projects Simphiwe Shazi told Engineering News in December 2012 that the manufacturing of the generator transformers for Medupi was 90% complete.

Almost all the transformers have been delivered to site and will be stored there until the civil works are completed. Work cannot begin on site until the civil works are 100% complete for the specific section that Siemens will be working in.
