A continuing decline in the performance of the Eskom coal fleet drove yet another “intensive” period of load-shedding in South Africa during the first six months of 2021, when rotational power cuts were implemented for 650 hours, or 15% of the time. A new Council for Scientific and Industrial Research (CSIR) Energy Centre analysis shows the average energy availability factor (EAF) of the coal fleet slumped to 61.3% during the period, materially below the 65% average EAF reported in 2020, as well as the 66.9% of 2019 and the 71.9% of 2018.
