South Africa: Eskom to implement stage 4 load shedding from Nov. 18 /update 1

Event

South Africa's energy provider Eskom issued a statement on Nov. 18 indicating that stage 4 load shedding would be implemented until further notice. The latest round of load shedding is due to the breakdown of generating units amounting to the loss of a third of generation capacity, low dam levels, and a shortage of diesel fuel.

Temporary commercial and communications disruptions are possible while load shedding and unscheduled interruptions are taking place. Cellular and mobile services could be affected. Trains may also experience delays if outages impact signaling devices or overhead wires. Power outages could also result in the temporary unavailability of essential services such as ATMs and filling stations.

There is an increased security threat during power outages. Blackouts could adversely affect security protocols, including alarm systems and electronic fences; opportunistic criminal activity could increase during electricity outages. Malfunctioning traffic signals could increase transport disruptions, and the lack of public lighting may elevate the risk of driving at night. Water supply outages or decreases in water pressure may occur in areas that rely on electrical pumps for water flow.

Context

Maintenance and breakdowns of generation units have resulted in over 2,400 hours, or 100 full days, of load shedding in South Africa in 2022. Load shedding requires switching off parts of South Africa's electric grid in a planned and controlled manner due to insufficient capacity or to avoid a countrywide blackout.

Authorities in the City of Cape Town will likely continue to implement support measures and supply electricity during load-shedding periods. Typically, city supply will move the stage down one level from the Eskom-announced load shedding level.

Advice

Charge mobile and communication devices when possible and ensure backup batteries are available. Plan for road travel delays due to possible malfunctioning or nonfunctional traffic lights in affected areas. Exercise caution when driving in recently impacted areas. Confirm business appointments. Verify that security systems are working. Park vehicles in secure areas, and complete ground movements before nightfall. Ensure that generators are functional and refuel devices where necessary.
