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

Client
Eskom.

Project Description
Medupi will be located on an 883 ha site in Lephalale, Limpopo.

It will be a dry-cooled coal-fired, baseload power-generating plant, comprising six 794 MW units, with a 4 764 MW installed capacity – the biggest of its kind with dry cooling in the world.

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 the older boilers, thereby providing greater efficiency.

It is the first baseload coal-fired station to be built in South Africa in more than 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
The cost of the project has increased from R91.2-billion to R105-billion.

Duration
The first unit, Unit 6, will be synchronised to the grid in 2014, instead of December 2013, as was previously announced.

Latest Developments

Between 500 and 1 000 workers protested at the Medupi power station on July 24.

"The protest turned violent, with stone-throwing and damage to two vehicles, but no one was injured as far as we are aware," the power utility said in a statement.
"The situation is under control and calm has been restored on site."

Eskom said most Medupi workers had been sent off site, but the utility was working to get operations back to normal as soon as possible.

The protest was reportedly related to dissatisfaction with one of the allowances that the workers receive, which is currently the subject of negotiation.

Most workers reported for work on July 25, despite it being a payday weekend.

Two weeks ago, Eskom said in a statement that the new power station would probably begin contributing to the national grid only in the second half of next year because of construction problems. The previous target was December 2013.
