Eskom has delivered its best system performance in nearly a decade, cutting diesel use to zero for two consecutive weeks, slashing unplanned outages to their lowest in eight years, and recording a daily Energy Availability Factor (EAF) of 82.04% – the highest since 2017.
The utility said its operational recovery is firmly on track, reporting record system performance that has reduced reliance on costly diesel generation and strengthened energy security nationwide.
Eskom said between 24 and 30 July, it did not use any diesel to support the grid – the second consecutive week without diesel expenditure.
“Year‑to‑date, diesel costs stand at R807.41 million, compared to R5.63 billion over the same period last year, representing an 85.67% reduction. This reflects improved generation performance and sufficient capacity to meet demand,” Eskom said.
