Johannesburg is battling widespread electricity outages as a bitter cold snap grips the country, with City Power warning residents to reduce their electricity consumption as demand reaches critical levels.
The electricity distributor says it is currently dealing with more than 2,400 outages across the city, placing additional pressure on already stretched repair teams.
The warning comes as extremely cold, wet and windy conditions move across large parts of South Africa, with the South African Weather Service forecasting disruptive snowfall in some areas and very cold conditions across the central and eastern parts of the country.
Gauteng is among the provinces experiencing the effects of the winter system, with temperatures expected to remain unusually low on Tuesday. Parts of the province have also been warned about the possibility of snowfall.
For Johannesburg residents, the cold has created a second problem, increased reliance on electricity.
Households are turning to heaters and other electrical appliances to cope with the freezing conditions, pushing demand on the City Power network higher.
City Power has urged residents to use electricity sparingly, particularly during peak periods, in an effort to reduce pressure on the network.
The distributor’s appeal comes against the backdrop of South Africa’s improved national electricity supply.
Eskom’s latest winter outlook reported hundreds of consecutive days without national load shedding and said the power system entered winter with improved reserve margins.
However, the current problems in Johannesburg highlight the distinction between national electricity supply and the condition of local distribution networks.
Even when sufficient electricity is available nationally, ageing or damaged municipal infrastructure can still leave individual neighbourhoods without power.
The extreme weather is also creating challenges for emergency services and motorists.
The City of Ekurhuleni’s Disaster and Emergency Management Services has urged residents to remain vigilant as severe weather affects the region.
Meanwhile, heavy snowfall is continuing in parts of the Eastern Cape, with authorities warning residents and motorists to take precautions as the cold-weather system moves through the country.
The latest weather system is expected to remain a major focus for authorities on Tuesday, with residents in affected areas urged to monitor official weather warnings and prepare for possible disruptions.
For Johannesburg, however, the immediate concern is two-fold, keeping vulnerable residents warm while preventing further strain on an electricity network already dealing with thousands of faults.
City Power’s appeal for reduced consumption is therefore not simply a routine power saving message.
With temperatures plunging and demand climbing, the next few days will test the resilience of the city’s electricity distribution infrastructure.
