State-owned electricity utility Eskom has provided some additional detail regarding the decision to continue operating 17 coal units across five power stations beyond their original decommissioning dates. The decision is in line with a May 23 determination by then Forestry, Fisheries and the Environment Minister Barbara Creecy to allow Eskom to operate Hendrina, Grootvlei, Arnot, Camden and Kriel at existing minimum emission standards (MES) plant limits until March 31, 2030.
