Load shedding in November 2023
Eskom shed 1 218 GWh of demand across 630 hours, affecting 30 of the 30 days in the month. The heaviest single day was 29 November 2023, when 89.2 GWh was shed. Separately, contracted industrial customers on interruptible supply were curtailed by 6.8 GWh. That is demand management, not load shedding.
How this month compared
Carbon intensity averaged 820 grams of CO₂ per kilowatt-hour, against a world average of 458 g/kWh in 2025 and an Africa average of about 530 g/kWh. Renewables (wind, solar PV, CSP and other renewables reporting to Eskom) supplied 8.6% of generation.
