ANNEXURE 6 Table 1: Summary of current annual pollutant emission rates, estimated annual average stack concentrations and Eskom’s requested emission limits

This fact sheet provides a detailed table and analysis of current pollutant emission rates (SO2, NOx, and PM10), estimated stack concentrations, and the emission limits requested by Eskom for 13 power stations. The document highlights inconsistencies in Eskom's reported data and argues that Eskom is effectively seeking exemptions from future Minimum Emission Standards (MES).

• Eskom is effectively seeking an exemption from the 2020 Minimum Emission Standard (MES) for SO2, which is 500mg/Nm3, for all 13 of its existing power stations because it has stated it will not retrofit Flue Gas Desulphurization (FGD) on any existing plants, planning it only for Medupi.
• The document identifies significant inconsistencies in Eskom's reported data, noting that 'current' annual total emission rates differ across different documents (AIRs and GI documents) and that calculated stack volumetric flow rates differ substantially from the values provided by Eskom.
• Eskom's requested NOx emission limits are aligned with a specific program to retrofit 'Low NOx' burners, but this program only applies to the Matla, Tutuka, and Majuba plants between 2021 and 2025.
• The document provides specific current annual emission rates for various plants; for example, Matimba has the highest SO2 emission rate at 309,262 t/yr, while Kriel has the highest NOx emission rate at 101,628 t/yr and the highest PM10 emission rate at 16,638 t/yr.
