South Africa: Eskom lowers load shedding to stage 4 nationwide Dec. 15 /update 4

Event

South Africa's energy provider Eskom announced that stage 4 load shedding would be implemented from 05:00 Dec. 15 until at least 05:00 Dec. 18. The utility has been altering its load shedding regime as generation units are taken off for repairs or return to service. Eskom has currently lost about 21,000MW of power due to planned maintenance and breakdowns. Further updates will likely be published in the coming days.

Temporary commercial and communications disruptions are possible during load shedding and unscheduled interruptions. Cellular and mobile services disruptions could occur. 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 significant levels 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. Eskom has indicated that increased levels of load shedding would be implemented over the next six to 12 months.

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 or two levels 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.
