Eskom energises a 500 MVA Transformer at the Ngwedi Substation near Rustenburg in North West Province
Monday, 12 December 2016: The Greater Rustenburg town and surrounding areas in the North West Province are a step closer to receiving a major energy boost as Eskom has energised and commissioned the first of the two 500 MVA power transformers at the newly built Ngwedi substation. This will provide improved flexibility and reliability of the network in the Greater Rustenburg area – home to numerous platinum mining houses.  This transformer marks a significant step towards the completion of the Medupi Power Station Integration Project. 
The Medupi Integration Project is one of the large-scale power delivery projects aimed at supporting the grid system between Limpopo and North West. Phase 2 of the Medupi integration comprises the construction of two substations, Ngwedi in North West and Borutho in Limpopo, as well as the construction of transmission lines from Medupi Power Station to both substations, which will interlink with the rest of the grid, consisting of approximately 732 km of high-voltage transmission lines and an additional 2000 MVA of transformation capacity.
The General Manager for Eskom Power Delivery Projects, Mr Naresh Hari, says the substation is required to provide for the expected load growth as a result of the developments in platinum mining operations taking place around the Rustenburg area which at present cannot be supplied by the existing transmission and distribution networks. On completion, this substation will strengthen and provide capacity to the transmission and distribution networks in the area.
Eskom commenced with construction activities at this R500 million substation project in July 2014, and the construction is still ongoing, with the second transformer expected to be energised in February 2017. The works entail the construction of a Main Transmission Substation (MTS) and associate transmission power lines, including the control building, telecommunications and road infrastructure. The substation will be a 400/132 kV step-down substation that will transform the 400 kV to 132 kV and it therefore links Ngwedi Substation to the existing 132 kV distribution network in the area.
The project has already created over 300 employment opportunities for which over 100 persons were employed from local communities. Thirty (30) local persons were also trained in various trades, including pipe laying, shutter hands, building carpentry, earthworks hands, and builders. Local people were employed from the nearby villages closer to Sun City, such as Ledig, Chaneng, Mafenya, Rasimone, Robega and Phatsima.  The project has also sourced various goods and services from local businesses and is also involved in a number of corporate social investment initiatives in the area.
