Eskom se biljoene

For years those were operated.  Eskom’s mega power stations Medupi and Kusile, which were intended to alleviate SA’s power constraints, have a multitude of serious design and technical flaws that are impeding their operation.  Somebody perhaps just pull the necessary plugs out to get more money from us, the tax payers.   Who paid billions thusfar and to whom?

Daar word al ‘n paar jaar droe krummels uitgegooi vanaf die elites en hoë lui van die Staatsorganisasies wat kwansuis bankrot is – en almal bevraagteken die jongste dat daar van buitelandse ingenieurs gebruik gemaak moet word om Eskom se probleme op te los.  Het daardie “ingenieurs” dalk kontakte met regeringslui, guptas of brics?  Al hierdie kragstasies is dan geopen en wat gewerk het.

Hoe het dit dan tot nou toe gewerk en skielik werk dit nie meer nie?  Hoekom miljoene rande spandeer as dit nie goed beplan is nie en aan wie is al die biljoene betaal sedert ontwikkelings plaasgevind het?  Hoekom as dit ingewy was operasioneel is, word daar nou “beurtkrag” toegepas?

Indien wel – wie en wat is almal betrokke

Watter kartelle was hierby betrokke?

Medupi is located on an 883 ha site in Lephalale, Limpopo, in South Africa.
Construction activities started in May 2007.

2018
The State-owned utility reported that Medupi was now expected to cost R145-billion, rather than the earlier revised estimate of R105-billion.
The cumulative cost incurred on the project for the year ended March 31, 2018, is R112.68-billion (March 2016: R105.2-billion), against the revised budget of R145-billion. All amounts exclude capitalised borrowing costs.

Client
State-owned power utility Eskom.

Project Description
Medupi will be a dry-cooled, coal-fired, baseload power-generating plant comprising six 800 MW units, with a total 4 800 MW installed capacity. It will be the fourth-largest coal-fired power plant and the largest direct dry cooling plant 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, compared with that of older boilers, thereby providing greater efficiency. Supercritical technology will result in  more efficient use of natural resources, such as water and coal, and will have improved environmental performance and footprint.

It is the first baseload coal-fired power station to be built in South Africa in more than 20 years and its delivery on schedule is viewed as critical.

The project is somewhat unique because Medupi is being built in reverse order – traditionally Eskom has always started building Unit 1 and ended with Unit 6. This new approach is the result of the rock agglomeration on the southern side of the site, which was excavated and reused for engineering fill on the northern side.

The project forms part of the utility’s integrated strategic electricity plan and is designed to be flue-gas desulphurisation ready.

The first unit, Unit 6, was first synchronised to the grid in the first quarter, beginning March 2015. On August 23, 2015, Unit 6 of Medupi became commercially operational.

Unit 5 was successfully synchronised to the national grid on September 8, 2016, ahead of schedule, and reached full load on December 17, 2016. After completing performance, reliability and compliance tests, the unit attained commercial operation on April 3, 2017, also ahead of schedule.

Unit 4 was synchronised in May 31, 2017, and achieved commercial operation status on November 28, 2017, ahead of the scheduled timeline of July 2018.

Unit 3 reached first synchronisation in April 2018.

The completion of the entire six-unit Medupi project has been revised to 2020/21

The remaining units at the Medupi project are progressing well against the revised schedule.

Medupi Unit 3 achieved first synchronisation in April this year, enabling it to feed electricity into the national grid during performance and optimisation tests. Eskom expects it to go into commercial operation in December 2018, ahead of the revised schedule.
