Eskom’s new build programme has increased generation capacity by 6,137MW

In South Africa, state-owned power company Eskom, has installed and commissioned a new transformer at the Acornhoek substation in the Bushbuckridge Local Municipality, Mpumalanga.

The objective of the project upgrade is to meet the growing electricity demand in Bushbuckridge, Acornhoek, Hoedspruit, Hazyview and other neighbouring towns like Phalaborwa.

The power utility said in a statement that the ZAR144 million ($10 million) project was initiated in September 2014 and will take shape in two phases.

The two phases include the replacement of two old transformers with two new transformers, which have bigger capacity to meet the increasing demand in the respective areas.

Phase one: transformer upgrade

Phase one of the project included the installation and commissioning of this transformer, which according to the utility “will enable the substation to carry much more load, thus ensuring that the areas fed through this substation have a more reliable power supply.”

Phase two: assembling of new transformer

The utility is in the process of phase two at Acornhoek, which includes civil works and the assembling of the second transformer. The second transformer is expected to be commissioned by April 2016.

Power system expansion

According to the power company, its nominal generating capacity in 2005 was 36,208MW. At this time did the utility implement a generation and transmission expansion programme, which will add an additional 17,384MW by 2021/22.

The most fundamental expansion projects include the 4,764MW Medupi and 4,800MW Kusile coal-fired power stations and the Ingula pumped-storage plant in the Drakensberg, which will deliver 1,332MW of hydropower during the peaking periods.

The utility added in a statement that its new build programme has increased generation capacity by 6,137MW, its transmission lines by 5,497km and its transmission substation capacity by 27,565MVA.
