Tshwane Substation fails again, prolonging East Pretoria blackout

Substation in Pretoria East

The City of Tshwane in Gauteng says it’s working hard to restore power in most parts of Pretoria East, including the Koedoespoort Substation, which went down on the 26th of last month and left residents without electricity for 12 days.

The substation went off again on Saturday, affecting 20 mini-substations.

Other areas affected include Faerie Glen, Lombardy, Lynnwood, and the CSIR, among others.

City spokesperson Lindela Mashigo says testing teams are continuing to work hard restore power.

“The contractor has completed the required cable work on the last mini substation together with overnight repairs by the deport team, this may allow a higher electrical load to be safely carried for the eight affected mini substations. Earlier this morning, the systems operators team met with the testing section on site to review and adjust protection panel settings to support stable restoration,” says Mashigo.
