Load shedding in February 2025
Eskom shed 246 GWh of demand across 114 hours, affecting 7 of the 28 days in the month. The heaviest single day was 23 February 2025, when 83.3 GWh was shed. Separately, contracted industrial customers on interruptible supply were curtailed by 4.0 GWh. That is demand management, not load shedding.
How this month compared
Carbon intensity averaged 833 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 8.2% of generation.
