Eskom, South Africa's state-owned power utility, has unveiled an optimistic power system update, projecting a significantly improved outlook for Winter 2025. For the first time in years, the utility anticipates no load shedding if unplanned outages are maintained below 13GW, solidifying a commitment to stabilising the nation's electricity supply.
The outlook reveals a sharp contrast to previous winters, as the likelihood of load shedding escalates only to a maximum of Stage 2 under the condition that unplanned outages rise to 15GW.
Last year, Eskom faced ominous predictions of Stage 5 load shedding. However, data shows a marked improvement with unplanned outages dropping by 3.1GW compared to 2024 figures, resulting in a forecast range of 13GW to 15GW, down from the previous year's range of 14GW to 17GW.
Operational advancements
According to Eskom's Group Chief Executive, Dan Marokane, the utility's operational performance has seen substantial enhancements, delivering energy 96% of the time in the last financial year compared to just 9.9% the year before. Additionally, diesel use was slashed by around 50%, translating to cost savings of approximately R16 billion, signifying a reduced reliance on emergency generation methods.
'This year's Winter Outlook prediction illustrates our operational improvement and efficiency,' Marokane noted, highlighting the operational benchmarks that underpin this year's forecast.
Despite facing recently implemented load shedding in the first four months of 2025, Eskom is in the process of implementing a strategic plan aimed at bolstering operational discipline to recover from such challenges.

Projections and performance indicators Unplanned outages saw a significant decrease, offering a substantial boost to generation capacity with averages dipping below earlier projections.
Planned maintenance activity has increased to 12.8%, marking an upward trend in organisational commitment to upkeep and efficiency.
Plant availability improved from 54.6% to 61% year-on-year, indicating a healthier return to service for Eskom's generation fleet.
Sales volumes rebounded, growing by 3.6% year-on-year, a sign of improved generation capabilities and stronger export activity.
The successful reconnection of Kusile Units 2 and 3 is also a noteworthy achievement, now operational with the flue gas desulphurisation system in place, while Unit 1 is expected to return to service next month. Furthermore, the Koeberg Unit 2 has reintegrated over 900MW back to service as part of its long-term operational project.

Eskom boosts grid by 2 550MW as cold front hits Gauteng
Eskom has returned at least 2 550MW of generation capacity to the national grid as severe winter weather grips the country. According to the South African Government News Agency ( the power utility is making steady progress in reducing maintenance operations, with the Energy Availability Factor (EAF) currently fluctuating between 61% and 64%. 'While system constraints are occasionally experienced, adequate emergency reserves are in place and are being strategically deployed to support demand during the morning and evening peak periods,' Eskom said. The utility warned that this week's cold front may drive up electricity usage, putting additional strain on the grid. The return of 2 550MW to service by June 9 is part of efforts to stabilise supply during peak hours. ALSO READ: City of Ekurhuleni and Eskom discuss municipal debt Progress is also being made at Medupi Unit 4, which was damaged in 2021. Commissioning activities are underway, and Grid Code compliance testing is expected to resume within the coming week. The unit is anticipated to return to service by the end of June. As more units return from long-term repairs, Eskom expects a reduction in diesel use, improving overall grid performance this winter. According to Eskom's Winter Outlook (until 31 August 2025), load-shedding may be avoided entirely if unplanned outages remain below 13 000MW. If breakdowns increase to 15 000MW, load-shedding would be limited to a maximum of 21 days over the 153-day period and restricted to Stage 2. Eskom also appealed to communities to avoid illegal electricity connections and energy theft, which often lead to transformer damage, equipment failure, and prolonged outages. 'These issues force us to implement load reduction to protect the network,' the utility said.

Scrutiny mounts over R86 million spent on South African Post Office business rescue
According to the AG report, Sapo is not meeting their payment commitments to their creditors, including statutory creditors, resulting in interest and penalties being charged on late or non-payment. Image: Independent Newspapers Archives Parliament's Standing Committee on Public Accounts (Scopa) has expressed serious concerns regarding more than R86 million paid to the South African Post Office (Sapo) business rescue practitioners (BRPs), Anoosh Rooplal and Juanito Damons, since their appointment in 2023. Members of Parliament on Wednesday questioned the revelation of zero consequence management at Sapo as wasteful and fruitless expenditure was sitting above R200 million since 2021. This comes as R152m remains unaccounted for in the current year, with further reports of R136m being written off by the BRPs. "I would like to understand that it is two people, that is already R86m spent on them, please Auditor-General, take us nicely. Did you have sight of what the R86m was paying for? What are the other consultants? What is the period of these people being there," asked MP Veronica Mente-Nkuna. "History has treated us badly with business rescue We saw with SAA that has turned itself around but the busines rescue process did hot have much contribution in turning it around." Executives for the Office of the Auditor-General (AG) clarified that the R86m paid to the two practitioners was regulated with caps and rates on what they could charge for, further explaining that they needed to contract independent expertise. Some of the key things were the actual turnaround plan and implementing the plan as well, They also needed someone on the ground to support management, closing the Section 189 legal involvement, and the involement of other practitioners such as tax, legal, evaluators and others. According to the AG report, Sapo is not meeting their payment commitments to their creditors, including statutory creditors, resulting in interest and penalties being charged on late or non-payment. The fruitless and wasteful incurred for the current year was R152m, however R136m was written off as result of the business rescue process for the current year. Similarly, the opening balance was decreased by R484m as a result of the business rescue process. Sapo's consequence management for fruitless and wasteful expenditure is inadequate, with delayed investigations, poor record-keeping, and weak disciplinary actions, undermining accountability and allowing financial inefficiencies to persist, the AG reported. "What is the Sapo's culture around fruitless and wasteful expenditure is marked by weak accountability, poor financial management—such as entering contracts without cash flow confirmation—and a tolerance for inefficiency, resulting in repeated financial losses," noted the AG report.. "Its consequence management is reactive and permissive, with delayed actions often justified by financial difficulties, undermining effective financial control." The AG said weak internal control environment around cashflow management, ineffective contract management, and lack of accountability were the main contributing root cause to the culture Sapo's fruitless and wasteful expenditure. Cash flow constraints further delay payments, leading to avoidable costs such as interest and penalties. The AG said weak consequence management stemmed from lack of leadership and oversight, delayed investigations, inadequate disciplinary action, and poor record-keeping of evidence supporting fruitless and wasteful expenditure cases, often excused by financial difficulties. The AG said executive management must enforce accountability on all responsible officials accountable for financial decisions and contract management through capacitating the Financial Misconduct Committee (FMC) in order to change the culture of fruitless and wasteful expenditure. It also recommended that the board to be appointed should strengthen oversight over the FMC, and the Department of Communications and Digital Technologies, together with the board, should ensure strict monitoring and consequence management.
