The Council for Scientific and industrial Research (CSIR) has confirmed that 2021 surpassed 2020 as South Africa’s most intensive load-shedding year to date, as the performance of Eskom’s coal fleet continued to deteriorate. Load-shedding occurred for 1 169 hours, or 13% of the year, with an upper limit of 2 521 GWh, representing a 40% increase compared with the 2020 load-shedding upper limit of 1 798 GWh.
