Load shedding in October 2022
Eskom shed 956 GWh of demand across 536 hours, affecting 28 of the 31 days in the month. The heaviest single day was 5 October 2022, when 66.0 GWh was shed. Separately, contracted industrial customers on interruptible supply were curtailed by 5.1 GWh. That is demand management, not load shedding.
How this month compared
Carbon intensity averaged 805 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 7.6% of generation.
