South Africa – State-owned power utility Eskom’s Medupi power station, in Limpopo, is achieving its critical milestones in the run up to its commissioning thanks to contractors such as engineering and construction group Kentz, who has provided the fabrication and installation of six air-cooled condensate (ACC) systems at the 4 764 MW coal-fired power station.
The ACC systems are responsible for converting steam after it has driven the turbine back into condensate that is recycled back to the boiler for reuse.
The first of six ACC units on the project with a power output of 794 MW, each played an integral role in Eskom’s Medupi Unit 6 synchronisation testing earlier this month.
The synchronisation entailed electrically connecting the generator to the national power grid in such a way that its power is aligned with other generators in the national fleet to produce and deliver electricity to South Africa.
“The Medupi project is important to Kentz not only because of the value it brings to South Africa but also because it has allowed Kentz to develop the Medupi Training Centre which empowers the local community. Electricity security is a big issue right now in South Africa and we are proud to be part of the solution,” says Kentz senior regional executive for Sub-Sahara Africa Carl Dyer.
Kentz, a member of ASX-listed SNC-Lavalin Group has been involved in the project since 2008. In addition to the fabrication and installation of the ACC systems, Kentz were also responsible for the supply, fabrication and installation of 26 000 t of structural steelwork, 11 000 t of ducting, 1 800 t of piping, and 40 000 t of mechanical equipment.
Kentz is sub-contracted to global supplier of process technology and solutions GEA, who in turn is sub-contracted to French energy solutions group Alstom. Alstom’s scope at Medupi consists of the supply, installation and commissioning of the turbine island, which includes the ACC Systems, and the ALSPA Series 6 plant control system.
