How this month compared
Carbon intensity averaged 774 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.
Figures are calculated from Eskom's published hourly data. Rooftop solar sits behind the meter and is not included.
