JOHANNESBURG - If you're in Gauteng, Eskom is asking you to switch off your lights and try to use electricity sparingly.
The power utility says it is facing an increased load on its transformers due to illegal connections.
The utility says that people are connecting illegally due to a significant drop in temperatures.
This has resulted in power outages in some parts of the province, particularly in Soweto.

Eskom's spokesperson for Gauteng, Amanda Qithi, said a number of transformers have been overloading.
"We ask people to keep themselves warm it could be blankets, hot water bottles and also dress warm just to make sure that they don't have to be using heaters," she said.
"It's just asking the communities to make sure that they use electricity more effectively as we are entering the winter season in Johannesburg," she said.
"It is really cold, we just need to make sure that we stay warm."
