Load shedding in January 2024
Eskom shed 691 GWh of demand across 576 hours, affecting 28 of the 31 days in the month. The heaviest single day was 31 January 2024, when 42.2 GWh was shed. Separately, contracted industrial customers on interruptible supply were curtailed by 4.1 GWh. That is demand management, not load shedding.
How this month compared
Carbon intensity averaged 797 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 9.0% of generation.
