Eskom to implement rolling power cuts as generation units break down

South African utility Eskom said on Tuesday it would implement rolling blackouts from 4pm until 10pm, and again the following day, after breakdowns in some generation units left the electricity system severely constrained. In a statement, Eskom said six generators had been returned to service at its Medupi, Tutuka, Kendal, Majuba and Grootvlei power stations the previous day, but the breakdown of four units overnight and on Tuesday morning, as well as a delay in the expected return to service of one, had left the grid under pressure.
