Eskom gives positive update as snow and cold grips South Africa

Power utility Eskom is expected to return at least 2,550MW capacity to the grid by evening peak on Monday as South Africa braces for severe winter conditions throughout the country this week.

The power utility said it is making “steady progress” in tapering down maintenance season with the Energy Availability Factor “fluctuating between 61% and 64%” last week.

“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, particularly as the country prepares for a forecasted cold spell in the coming week.

“We plan to return a total of 2,550MW of generation capacity to service ahead of the evening peak [today] to further stabilise the grid,” the power utility said.

In May Eskom shared its Winter Outlook which covers the period from 1 May 2025 to 31 August 2025, noting that that load shedding would be avoided if unplanned outages remain below 13,000 MW.

If outages reach 15,000 MW, load shedding would be limited to Stage 2.

Eskom revealed that Medupi Unit 4 is in the last phases of recovery following damages sustained in 2021.

“Commissioning activities are currently underway and Grid Code compliance testing is expected to resume in the coming week. The unit is anticipated to return to service within June 2025.

“Diesel usage is expected to decline further as more units return from long-term repairs and maintenance activities are reduced, increasing available generation capacity.

“The Winter Outlook…covering the period ending 31 August 2025, remains valid. It indicates that load shedding will not be necessary if unplanned outages stay below 13 000MW. If outages rise to 15 000MW, loadshedding would be limited to a maximum of 21 days out of 153 days and restricted to Stage 2,” Eskom said.

The power utility has encouraged communities to “avoid illegal connections and energy theft” even as the winter period rolls in.

“These activities often lead to transformer overloads, equipment failures, and in some cases, explosions and extended outages, prompting the need for load reduction to protect the network.

Electricity minister: We enter winter on a much better footing

Electricity and Energy minister, Dr Kgosientsho Ramokgopa, is optimistic that South Africa is in for a load shedding-free winter, despite the implementation of load shedding this week.

The minister briefed the media in Pretoria on Wednesday on the status of electricity generation in the country, following Eskom’s announcement that load shedding would be implemented during evening peak over the next few days.

He explained that additional units have been synchronised to the grid since last winter, putting Eskom in a stronger position.

“All of the things that we shared with the country regarding the winter outlook remain valid.

“In the winter outlook, we made the point that we enter winter 2025 on a much better footing than we did the winter of 2024. We are entering this winter confidently in that Koeberg unit 2 was synchronised to the grid on 30 December 2024. Koeberg unit 1 which is currently on outage…we are projecting that it’s going to come back in July 2025 when we’re at the peak of winter.

“We have also successfully synchronised Kusile unit 6 to the grid in March…that’s an additional capacity on the grid, approximately 800MW,” he said.

Additionally, Medupi’s unit 4 is also expected to be used this winter as opposed to last year.

“From a structural point of view…essentially, we’ve got 2500MW of additional capacity [as opposed to 2024]. That’s why when we shared [the winter outlook] with the country…we were very bullish, very optimistic about the prospects of a load shedding free winter or at worst stage 2 load shedding,” the Minister said.

In a statement on Tuesday, Eskom explained that the implementation of load shedding was mainly due to two factors: the delayed return of generation units from planned maintenance amounting to 3120MW of capacity and an additional loss of 1385MW in unplanned breakdowns.

This pushed the losses to more than 13 000MW – beyond the power utility’s limit where load shedding can be avoided.

Ramokgopa explained that Eskom had announced that it would taper down planned maintenance significantly to be able to absorb unplanned losses but had failed to do so – leading to the current situation.

“I think we’re getting to a point where there has to be consequence management if there is a promise to bring a unit by this date [and it doesn’t occur]. That’s a planning function and in this instance, we have not carried ourselves very well and that’s why you see these outage slips.

“[We must] ensure that we get the units back on track. They must generate the megawatts at the time we have made the promise because the resources were made available.”

The minister offered his apologies. “It’s really not about the engineering performance of the units. It has to do with how we were able to manage this situation. We are having difficult, hard and candid conversations with the executive team to ensure that we are not experiencing these lapses,” Ramokgopa said.

Eskom delivers winter load shedding forecast

Eskom says it is working to prevent load shedding this winter, citing improved operational performance and the anticipated addition of new generation capacity to the grid.

For load shedding to be avoided, unplanned outages must remain below 13 gigawatts (GW).

“If outages increase to 15GW, load shedding would be limited to a maximum of 21 days out of 153 days at stage 2 – an improvement over the prior winter’s worst-case prediction of stage 5 load shedding,” Eskom Group chief executive, Dan Marokane, said on Monday.

Addressing a media briefing on Eskom’s State of the System for the 2024/2025 financial year, Marokane said the improved winter outlook is due to a 3.1GW decrease in unplanned outages compared to the previous year. 

As a result, the forecast range has been lowered to 13-15GW, down from 14 -17GW in winter 2024. 

Last winter had no load shedding, with average unplanned outages at 12.3GW – significantly below the winter 2024 base-case projection of 14GW.

“This year’s winter outlook prediction is built on an improvement in operational performance and overall efficiency. Load shedding was the lowest in Eskom’s last financial year (FY) 2025 than in the previous two years. 

“In FY 2025, we delivered power 96% of the time. In the previous year, the figure was just 9.9%. Our diesel open cycle gas turbines (OCGTs) were utilised approximately 50% less in FY 2025 compared to the two previous financial years, saving around R16 billion,” the CEO said.

Against this progress, Eskom has seen some setbacks in operational excellence, as evidenced by the recent load shedding requirements between January to April 2025. 

“A targeted plan has been put in place to reinforce operational discipline and accelerate recovery initiatives to address the root causes related to the recent load shedding events,” Marokane said.

Minister of Electricity and Energy, Dr Kgosientsho Ramokgopa, said Koeberg unit 1 has received the long-term operating go-ahead from the regulator to ensure 20 years of additional life. 

“We have been able to restore Kusile unit 2 and 3. Kusile unit 1 will be placed back in its original form before the end of May. The three units at Kusile will give us [additional] megawatts (MW) during the winter period.

“Kusile unit 6 has been synchronised to the grid. It is yet to be in commercial operation. It is a technical issue. It is [providing electricity] and at times, it must be taken out to be fixed. Once it gets into commercial operation, we will get the long-term benefits of the unit.

“We plan to bring back Medupi unit 4 back to service during winter. It has been out of service for about four years. We are expecting to get about 800MW in the middle of winter,” Ramokgopa said.

The minister said load reduction will remain in place to protect the equipment and as a safety precaution to protect the lives of those who are close to the infrastructure when it gets overloaded due to rampant illegal connections.

From 1 April 2024 – 31 March 2025, Eskom implemented load shedding for 13 days compared to 329 and 208 in the two previous years, respectively.

Marokane said Eskom supplied South Africa with more electricity and reduced load shedding without the extensive use of diesel during the period under review.

“We had a 45% reduction in diesel consumption against the backdrop of the highest send out in the last three years and the lowest load shedding days.

“We used the OCGTs very tactically to support the high vulnerability and once we have our capacity, you will see the diesel expenditure going down significantly,” he said.

According to Eskom Group executive for Generation, Bheki Nxumalo, Eskom has continued to maintain high levels of planned maintenance as part of efforts to improve fleet reliability in preparation for the high winter demand, while also meeting environmental licence conditions and regulatory requirements.

“We have evolved our Generation Recovery Plan to ensure our data-led analysis into the delays in returning units from outages on time, which has caused our fleet to be constrained and not able to accommodate a sudden loss of units, receives intense management focus, as we use our ‘high challenge, high support’ culture to support our teams to rectify this situation,” Nxumalo said.

Electricity wheeling changes for South Africa

The updated Regulatory Rules on Network Charges for Third-Party Transportation of Energy have been released by the Department of Electricity and Energy.

The updated rules, also referred to as the electricity wheeling framework, were revealed by minister Kgosientsho Ramokgopa during a media briefing on Tuesday.

Wheeling refers to the transmission of electricity from a private generator to an end-user via existing transmission or distribution infrastructure. It enables businesses or municipalities to buy power directly from independent producers, using the national grid to deliver it—reducing reliance on Eskom and supporting energy diversification.

The minister touted the move as the “most consequential intervention” in South Africa’s electricity sector.

“It’s going to help us remake the energy and electricity landscape in the country and…bring into life what was envisaged in the Energy Action Plan that the President enacted in July 2022.

“It’s also consistent with our objective of ensuring that we are able to achieve energy security in the country. We are able to diversify generation sources and we don’t only rely on Eskom for electricity generation in the country,” he said. 

Conditions for third-party participation include:

  • Participants must be licensed and registered with the National Energy Regulator of South Africa (NERSA);
  • Power purchase agreements, connection and use-of-system agreements must be appropriately concluded;
  • Grid code compliance and auditable metering required.

Open access

The updated wheeling framework is aimed at supporting open access to the electricity network which will allow consumers to choose power sources – enabling competition and lowered electricity prices.

The rules are also aimed at: 

  • Non-discriminatory access: Ensuring equal access to the grid for all users.
  • Cost reflective tariffs: Charges to reflect the actual cost of network use.
  • Fairness and equity: Balance the interests of customers and licensees with non-biased tariffs.
  • Transparency: Promote unbundled tariffs that show true costs, subsidies and levies.
  • Network reliability: Maintain the integrity of the security of the grid during wheeling.
  • Standardisation: Create consistent processes across all network service providers.
  • Regulatory certainty: Reinforce NERSA’s role in governing fair and transparent access.
  • Just Energy Transition: Enable access to renewable energy through wheeling.

The minister said this brings the reforms announced by the president to life.

“…We are democratising this space. We are not just relying on Eskom as a sole generator of electricity, there will be multiple generators of electricity. And with competition comes efficiency, comes innovation, research and investment, and we are likely going to drive the prices down. 

“That’s why when we talk about affordable electricity, these are part of the elements [and] the components that are going to make it possible for us to make energy affordable for everyone, including the poor and downtrodden and those that are in villages, those are who are in peri-urban areas,” Ramokgopa said.

Energy Action Plan

The EAP was announced by President Cyril Ramaphosa in July 2022 and is coordinated by the National Energy Crisis Committee (NECOM) under the leadership of the Minister.

The plan aims to reduce the severity and frequency of load shedding in the short term and achieve energy security in the long term through five key interventions:

  1. Fix Eskom and improve the availability of existing supply
  2. Enable and accelerate private investment in generation capacity
  3. Fast-track the procurement of new generation capacity from renewables, gas and battery storage
  4. Unleash businesses and households to invest in rooftop solar
  5. Fundamentally transform the electricity sector to achieve long-term energy security

Electricity minister assures stage 6 load shedding temporary

Minister of Electricity, Kgosientsho Ramokgopa, has reassured South Africans that the current load shedding is a temporary issue, and that the country will be out of the “difficult position” by the end of this week.

The minister said that “we continue to be on the right path in relation to out quest to ensure that we are able to eliminate load shedding”.

“The end of load shedding is within touching distance,” he said, adding that a number of units are due to come back online including Medupe at the end of March, with Kusile Unit number 6 set to be synchronised in March.

The announcement follows Eskom’s declaration of Stage 6 load shedding early on Sunday morning (23 February), following nearly 20 days without interruptions. Eskom indicated that it would consider lowering stage 6 on Monday.

The power utility explained that Stage 6 load shedding was needed to replenish emergency reserves and prepare for the week ahead.

Ramokgopa addressed the media shortly after Eskom’s announcement, attributing the load shedding to multiple power-generating units tripping, which led to a drop in generation capacity. He explained that on Saturday, Eskom lost 3,000 megawatts, which initiated a series of events, escalating load shedding from Stage 3 to Stage 6.

Five units were lost at Majuba Power Station on Saturday, while a unit at Medupi also tripped. Four units at Camden Power Station went offline on Sunday morning. More than 7,000MW of capacity was offline due to scheduled maintenance.

“We were at Stage 3 when we went to bed, but after the incident at Camden at 1:30 AM, we had to increase it to Stage 6,” Ramokgopa said.

While he acknowledging the disruptions, the minister stressed that there was no evidence of sabotage. “There is no sabotage based on what we see. We can explain the cause, and we are addressing it,” he said.

Ramokgopa remains confident that the country will emerge from this situation by the end of the week, though he noted that setbacks may occur. Despite the challenges, the minister is hopeful that the situation will improve in the coming days, ensuring a more stable electricity supply for South Africa.

Developing…Eskom on Monday downgraded its load shedding from stage six to four.

This follows the successful recovery of all five units at Majuba, two units at Camden, and one unit at Medupi since Saturday, totalling eight out of 10 generation units that had tripped this weekend.

“The return of these units comes after identifying the root causes of multiple unit trips, which were unconnected and purely technical in nature,” it said. “Additionally, emergency-reserves replenishment is progressing well.”

Planned maintenance stands at 7 706MW.

Budget speech: What property investors should expect

South Africa’s upcoming national budget will face intense scrutiny, with analysts focusing on key areas such as the debt-to-GDP ratio, government spending, and potential risks that could lead to further fiscal slippage, says Waldo Marcus, Director at TPN from MRI Software.

In the medium-term budget policy statement (MTBPS) of October 2024, tax collections for the 2024/2025 financial year fell short of expectations.

However, the latest data indicates that tax revenue has grown by 5.3% in the current financial year, while government spending has only increased by 4%. This raises the question: Could the National Treasury have achieved its elusive target of a primary budget surplus?

Despite these improvements, South Africa’s growing debt remains a pressing concern. Debt-to-GDP is projected to peak at 75.5% in 2025/2026, well above the 60% threshold considered the maximum sustainable debt ratio for emerging markets like South Africa.

“The hope is that enough has been done to stabilise the government’s debt ratios and that any new challenges will only require political resolve for structural change without fiscal fallout or demands,” said Marcus.

“The inflation rate is better than expected, and the implementation of the two-pot retirement system enabled around R43 billion in retirement savings to be released into the economy, also providing a boost to SRS.”

The economy, however, still faces a number of risks, he said. GDP growth is lower than expected, keeping the State’s finances in a precarious position. Government has overspent for years, relying on borrowings to keep its lights on, while the tax base remains anaemic.

“This is unsustainable, especially as the cost of borrowing has increased and rating agencies consider more variables.”

In early February 2025, the US administration issued an executive order reducing support to South Africa, potentially jeopardising the renewal of the African Growth and Opportunities Act (AGOA), which grants South Africa approximately $4 billion in preferential exports.

The move also freezes US-backed credit guarantees and development financing, potentially leading to higher borrowing costs for the country.

If credit rating agencies downgrade South Africa’s debt outlook, borrowing costs could rise even further.

Moody’s has cautioned that escalating political tensions between the US and South Africa could stifle economic growth, particularly if the situation leads to trade restrictions or dampens foreign investor sentiment.

During his annual State of the Nation Address (SONA), Marcus noted that president Ramaphosa committed government to focus on underperforming municipalities, including the establishment of professionally managed utilities for water and electricity provision to ringfence revenue to ensure appropriate infrastructure investment and the efficient delivery of local services.

This commitment must be reflected in the budget with an appropriate allocation, he said.

Property values tend to decline in poorly managed municipalities. Conversely, well-run municipalities with maintained public infrastructure and safe public spaces remain attractive to property investors, tenants, and businesses.

Government is aware of municipalities’ need to improve their ability to collect the rates and taxes owed to them. Eskom has warned that unless municipalities pay what is owed, the power utility will be forced to approach National Treasury for another bailout.

“Ultimately, South Africans will have to fund the deteriorating state of provincial and municipal finances,” said Marcus. Municipal debt to Eskom grew from R28 billion in March 2020 to R107 billion by mid-December 2024.

In addition to the usual increases in sin taxes, analysts will also be watching for other tax increases to bolster South Africa’s fiscal position.

The property sector is impacted by numerous trends including confidence levels, employment rates, interest rates and inflation rates, among others.

A stable employment rate ensures that property vacancy rates are kept low while lower interest rates after a prolonged period of high interest rates may see some tenants shift to property ownership.

In 2024, average residential rental vacancies were the lowest since the TPN Vacancy Survey was first published in 2016.

“It will take time for the three consecutive interest rate cuts of 25 basis points each in recent months to filter through to consumers. Once they do, we expect to see an increase in residential property sales, particularly in well-run municipalities,” said Marcus.

The property sector has been challenged in recent years by escalating municipal costs, failing public infrastructure, loadshedding, the cost of capital and high interest rates, putting increased pressure on property developers and investors to enhance operational efficiencies in order to sustain returns.

“Given government’s limited fiscal space, the property sector will watch keenly how finance minister Enoch Godongwana balances numerous competing priorities in this year’s budget announcement to improve investment perception.”
