Data Requirements for calculating the Carbon Emission Factor (CEF) for the South African grid

General Information

• Eskom CEF calculator:   Fuel consumption     Electricity Generation    (updated September 2020)
• CO2 Emissions (Refer Eskom's Historical Green House Gas Emissions​)    (updated October 2018)​

Other Information Required

Grid specific information and data:

• Please refer to National Energy Regulator of South Africa (http://www.nersa.org.za/ ) for information and data on non-ESKOM electricity generation sources.

Default Values (IPCC)

• Net calorific values (NCV):
