Roosevelt Park substation’s upgrades are complete

November 22nd, 2019, Published in Articles: EE Publishers, Articles: Energize

The Roosevelt Park substation in Randburg, which had been responsible for the many power outages over the years, has been refurbished by City Power at a cost of R133-million. This substation, like many others across the city, is 65 years old. Refurbishments had not been undertaken in over 25 years. Over the past three years City Power has committed billions of rand to building and upgrading 13 substations across the city.

Executive Mayor of Johannesburg, Herman Mashaba, and the MMC for Environment and Infrastructure Services, Cllr Nico de Jager, at the official opening of the refurbished substation.

The Roosevelt Park substation upgrade includes two new 88 kV lines which supply power from the Delta substation, providing greater redundancy and stability for the network for the next 40 years. Furthermore, the substation has been installed with four 45 MVA transformers, a state-of-the-art control plant, three new feeder boards, and a standby board.

The control plant improves safety for City Power technicians when they need to work on the equipment. The new feeder boards also enable City Power to connect new customers to the substation without putting undue pressure on the electricity network. The upgrade of this substation is therefore very important, not only to these affected residents, but also to the entire City of Johannesburg’s electrical network.
