South African utility Eskom said on Tuesday it would be forced to resume rotational power cuts from midday to 22:00 due to breakdowns in its generating units which slashed power supply. "Eskom regrets to inform the public that due to a severely constrained generation system as a result of multiple unit breakdowns, it has become necessary to implement stage 2 load shedding," the state-owned company said, warning this was likely to persist for the rest of the week.
