Power grid remains stable - Eskom
Eskom says the power system remains stable and continues to demonstrate resilience in response to increased electricity demand.
Eskom spokesperson, Daphne Mokwena, says sufficient emergency reserves are in place and are strategically deployed to support demand during morning and evening peak periods.
"During the week of 13 to 19 June, planned maintenance averaged at 3,659MW, resulting in a decline in planned outages. During the same period, the Energy Availability Factor (EAF) ranged from 60% to 63%, with a month-to-date average of 60.48%,” said Mokwena.
She says to further enhance grid stability, the power utility plans to return a total of 2,730 megawatts of generation capacity to service ahead of the evening peak on Monday.
"As of today (Friday), unplanned outages amount to 12,892MW, while the available generation capacity stands at 31,681MW, excluding the 720MW contribution from Kusile Unit 6, which is not yet in commercial operation. This capacity is sufficient to meet the projected peak demand for tonight, which is expected to reach 28,425MW.”
"The year-to-date open-cycle gas turbine (OCGT) load factor stands at 11.73%, representing a 0.25% decrease from the previous week. This is higher than the 5.78% recorded during the same period last year.”
"Diesel usage is expected to decline as more units return to service from long-term repairs and maintenance activities are reduced, increasing available generation capacity."
