For coal-fired plants with a rated thermal input of 300 MW or more, dust concentrations must be measured continuously for each flue, while SO2 and NOx should be measured continuously for at least one unit per plant. Eskom intends to have continuous emission monitoring systems installed on all units of existing coal-fired power stations by 2074, and on all units of new coal-fired plants of 300 MW or more constructed from 2010 onwards.","ai_generated":true,"unit":"cer-000424#insight-1","date_modified":"2026-08-17"},{"text":"The submission outlines technical standards for monitoring and reporting.
