JOHANNESBURG, South Africa — South Africa’s national power utility, Eskom, has achieved a major operational milestone under its Generation Recovery Plan, marking 420 consecutive days without load shedding. This sustained period of grid stability, which began on 16 May 2025, highlights the tangible effectiveness of targeted fleet recovery initiatives in securing the country’s electricity supply.
During the preceding financial year, power interruptions were strictly limited to a mere 26 hours spread across just four days in April and May 2025. This consistent delivery of energy security is largely attributed to a climbing Energy Availability Factor (EAF) and a sharp decline in unexpected breakdowns across the network. For the current financial year-to-date, the EAF has climbed to 64.82%, up from 64.29% the prior week, and marking a substantial 6.09% year-on-year increase from the 58.73% recorded during the same timeframe last year.
The long-term trajectory of the Generation Recovery Plan remains equally promising. Compared to the corresponding period three years ago, the EAF has surged by 9.89%, effectively restoring 5.0GW of generating capacity to the national grid. This significant gain is fueled by fewer unplanned outages and increasingly dependable performance across Eskom’s diverse power stations.
Recent operational data underscores this dramatic turnaround. In the past week, unplanned outages dropped to 8,396MW, a stark contrast to the 13,619MW logged during the equivalent period last year. This 5,223MW reduction exceeds the total generating capacity of a massive facility like the Kusile power station. Consequently, the Unplanned Capacity Loss Factor (UCLF) has dramatically improved to 17.49%, down from 28.67% a year ago, validating the strategic gains achieved through Eskom’s recovery roadmap.
Looking at scheduled upkeep, the period between 3 and 9 July 2026 saw planned maintenance strictly aligned with Eskom’s sustainability and reliability objectives. The Planned Capacity Loss Factor (PCLF) held at an average of 9.15%, an improvement over the 9.68% seen during the same period last year. Furthermore, the utility is currently holding 3,530MW in cold reserve as a strategic buffer, guaranteeing system adequacy amid excess generation capacity.
Financial efficiency has also seen remarkable improvements alongside operational gains. Spending on diesel—utilized selectively during peak demand to fuel Open Cycle Gas Turbines (OCGTs)—has plummeted to R796.57 million for the current financial year-to-date. This represents a massive 84.82% cost reduction compared to the R5.25 billion spent during the same period last year, signaling both major fiscal savings and a diminished reliance on expensive diesel-fired generation.
Reinforcing this positive momentum, Eskom’s Winter Outlook, which was published on 22 April 2026, continues to forecast zero load shedding for the winter season spanning 1 April to 31 August 2026. The utility maintains that its ongoing commitment to the Generation Recovery Plan will continue to deliver the operational flexibility required to manage periods of higher seasonal consumption.
