The End of an Era: South Africa Powers Up
For the better part of a decade, load shedding defined the South African investment narrative. Rolling blackouts eroded GDP, inflated operating costs, drove capital flight, and sustained a persistent risk premium on JSE-listed equities. Businesses from Johannesburg to Cape Town ran on diesel generators, cold chains broke down, and consumer confidence cratered under the weight of unpredictable power cuts. That narrative is now reversing at speed.
Since March 26, 2024, Eskom has not implemented a single round of load shedding. By July 2024, the country had logged 121 consecutive days without cuts — a milestone that would have seemed unthinkable just twelve months earlier. The CSIR confirmed that total load shedding volumes fell approximately 76% in 2024 compared to 2023, and the improvement has only accelerated: in the first semester of 2025, just 749 GWh were shed versus 4,126 GWh in S1 2024, an 82% decline.
This is not a temporary reprieve. It reflects deep operational restructuring at Eskom, regulatory reform, and a shifting energy mix that increasingly incorporates private renewable generation. For investors, it means the single largest structural drag on South African earnings is lifting — and the beneficiaries span nearly every sector of the JSE.
Eskom's Operational Turnaround
The numbers tell a compelling story of operational rehabilitation that few analysts would have predicted even two years ago:
| Metric | FY2023/24 | FY2024/25 | FY2025/26 (YTD) |
|---|---|---|---|
| Energy Availability Factor (EAF) | 54.6% | 60.6% | ~65.4% |
| Diesel expenditure | R33 billion | R17 billion | R10.1 billion |
| Days without load shedding | Sporadic | 121+ consecutive | Ongoing |
| Net profit | Loss | Improving | ~R16B (est. March 2026) |
| Load shedding volume (S1) | 4,126 GWh | 749 GWh | Minimal |
The EAF improvement from 54.6% to over 65% represents a fundamental shift in generation reliability. At 54.6%, Eskom was operating well below the threshold needed to keep the lights on; at 65%, there is meaningful surplus during off-peak periods. Diesel expenditure — which ballooned as Eskom ran open-cycle gas turbines around the clock to plug generation gaps — has dropped by nearly 70% from its peak. This alone represents billions of rands in savings that flow directly to Eskom's bottom line. The utility is on track to post a net profit of approximately R16 billion by March 2026, its first in years.
The institutional architecture is also transforming in ways that should prove durable. The National Transmission Company of South Africa (NTCSA) commenced trading on July 1, 2024, separating transmission from generation — a critical reform that enables competitive entry. The Electricity Regulation Amendment Act, signed on August 16, 2024, formalizes the opening of the generation market to independent power producers. And Eskom's R254 billion debt relief package over three years provides the fiscal breathing room to sustain investment in both scheduled maintenance and new capacity additions.
Eskom's winter 2025 outlook is cautiously optimistic: no load shedding is expected provided unplanned outages remain below 13,000 MW. While this threshold could be tested during peak winter demand, the margin of safety has widened considerably compared to previous years.
Macro Recovery: Slow but Real
The macroeconomic picture is gradually improving, though South Africa's recovery remains modest by emerging market standards. Growth is accelerating from a very low base, constrained by structural challenges that extend well beyond electricity supply.
| Indicator | 2023 | 2024 | 2025 (est.) | 2026 (est.) |
|---|---|---|---|---|
| GDP growth | +0.7% | +0.6% | +1.1% | +1.5-1.8% |
| Load shedding GDP drag (Fitch est.) | -0.6 p.p. | Diminishing | Minimal | — |
| SARB estimated growth impact | -0.7 to -3.2 p.p. | Easing | — | — |
Fitch estimated that load shedding reduced GDP growth by approximately 0.6 percentage points per year over five years — a cumulative loss of roughly 3 percentage points of GDP that South Africa will never recover. The SARB's models placed the annual impact even higher, at between 0.7 and 3.2 percentage points depending on the severity and duration of cuts. As this drag lifts, the base case for GDP growth improves structurally — even without dramatic policy reform. The 2025 projection of +1.1% may seem modest, but it represents a near-doubling from 2024's +0.6%, and the trajectory points to further acceleration into 2026.
Two additional governance catalysts bolster the outlook and deserve close attention from investors. South Africa exited the FATF grey list on October 24, 2025, removing a significant overhang for financial sector flows and reducing compliance costs for cross-border transactions. The formation of the Government of National Unity (GNU) following the 2024 elections has also meaningfully reduced political uncertainty, with the RMB/BER Business Confidence Index improving post-GNU formation as the market prices in greater policy continuity.
Sector Analysis: Who Benefits Most?
Retail — The Biggest Direct Beneficiary
Retailers bore the brunt of load shedding through multiple channels: diesel generator costs that ran into hundreds of millions of rands annually, cold chain disruption that forced write-offs of perishable inventory, reduced trading hours that compressed revenue, and consumer spending erosion as households diverted budgets to their own backup power solutions. The reversal of these pressures is powerful and immediate.
Shoprite (SHP) was spending approximately R100 million per month on diesel at Stage 6 load shedding, and management explicitly warned that persistent blackouts could reduce group profits by roughly 10%. That cost is now largely eliminated, flowing directly to operating margins. The impact extends far beyond diesel savings: normalized trading hours mean higher revenue per store, intact cold chains reduce inventory losses, and improving consumer confidence supports discretionary spending.
Across the broader sector, Pick n Pay (PIK), Mr Price (MRP), Clicks (CLS), Pepkor (PPH), Woolworths (WHL), and Spar (SPP) all stand to benefit from normalized operating costs and improving consumer sentiment. The operational leverage is significant: these are largely fixed-cost businesses where incremental revenue drops disproportionately to the bottom line.
REITs — Normalized Operating Costs and Distribution Recovery
South African property companies spent heavily on backup generation infrastructure — generators, fuel storage, UPS systems, and maintenance contracts — driving up operating costs and compressing distributable income. Many REITs were absorbing these costs rather than passing them through to tenants, squeezing distributions at a time when global property yields were already under pressure from rising rates.
With load shedding fading, the sector can expect a meaningful reversal in operating cost trends. Key names include Growthpoint (GRT), the largest South African REIT, Redefine (RDF), Hyprop (HYP), Attacq (ATT), Equites (EQU), and NEPI Rockcastle (NRP). The sector's ability to pass through reduced utility costs — or reinvest savings in tenant retention and property upgrades — will be a key differentiator in coming results. For yield-focused investors, the normalization of distributions represents an attractive recovery play.
Mining — Improved but Transnet-Constrained
Mining production rose 2.3% in Q3 2025, led by a strong performance in PGMs. However, the picture is uneven: gold, iron ore, and diamond output all declined, and the sector faces a binding constraint that electricity improvements alone cannot solve — Transnet.
Approximately 40% of chrome and manganese exports are now trucked to port at a 40% cost premium due to persistent rail failures. Despite record chrome and manganese export volumes (a testament to demand), the logistical bottleneck caps the sector's ability to translate production gains into profit. Until Transnet's rail and port infrastructure is rehabilitated — or private sector participation reaches meaningful scale — the mining sector's earnings recovery will remain structurally capped below its energy-adjusted potential.
| Sub-sector | Key stocks | Outlook |
|---|---|---|
| PGMs | Impala Platinum (IMP), Anglo American Platinum (AMS), Sibanye-Stillwater (SSW), Northam Platinum (NHM) | Positive (energy relief) but logistics-constrained |
| Gold | Gold Fields (GFI), Harmony (HAR), DRDGOLD (DRD) | Mixed — commodity price-driven |
| Diversified | African Rainbow Minerals (ARI), Assore (ASR) | Rail-dependent, high operational leverage |
Banking — Credit Quality Improvement
Banks benefit indirectly but meaningfully through improved credit quality as households and businesses face fewer disruptions, lower operating costs, and gradually improving economic conditions.
| Metric | 2023 | 2024 | Direction |
|---|---|---|---|
| Credit loss ratio | 102 bps | 89 bps | Improving |
| Change | — | -13 bps | Positive for earnings |
The 13 basis point improvement in credit loss ratios reflects easing economic stress across the consumer and SME lending books. Lower default rates translate directly to higher earnings, as provisions that would otherwise absorb revenue are released or simply not required. FirstRand (FSR), Standard Bank (SBK), Absa (ABG), Nedbank (NED), and Capitec (CPI) are all positioned to benefit from improved asset quality, gradually rising credit demand, and the positive confidence effects of the FATF grey list exit.
The banking sector also benefits from a second-order effect: as economic activity normalizes, transaction volumes rise, supporting non-interest revenue streams including card payments, merchant services, and insurance cross-selling.
Renewables — The Emerging Structural Play
The energy transition is creating entirely new investment vehicles on the JSE. Greencoat Renewables (GCT) listed on the JSE AltX in June 2025, offering direct exposure to operating renewable generation assets with contracted cash flows. Reunert is positioning as a key enabler through commercial and industrial (C&I) solar solutions and battery energy storage systems — a market segment that has exploded as businesses seek to reduce their dependence on the grid regardless of load shedding levels.
For broader thematic exposure, the JSE Alternative Energy index (JS6012) tracks the growing universe of energy transition companies, while the Sygnia Sustainable Economy ETF (SYGSE) provides a diversified, ESG-aligned vehicle for investors seeking structural growth exposure.
Sector Impact Summary
| Sector | Mechanism | Key Stocks | Impact Magnitude |
|---|---|---|---|
| Retail | Diesel savings, extended hours, cold chain | SHP, PIK, MRP, CLS, PPH, WHL | High |
| REITs | Reduced opex, improved distributions | GRT, RDF, HYP, ATT, NRP | High |
| Banking | Credit quality, consumer confidence, FATF exit | FSR, SBK, , , |
Key Risks
Transnet remains the binding constraint. Even as electricity supply normalizes, South Africa's rail and port infrastructure continues to throttle export capacity, particularly for bulk commodities. Approximately 40% of chrome and manganese — two commodities where South Africa holds dominant global market share — are shipped by road at prohibitive cost premiums. Until Transnet is restructured or private sector participation scales, mining and manufacturing will underperform their energy-adjusted potential.
Manufacturing weakness persists. Despite improved electricity supply, manufacturing was the principal negative contributor to GDP in Q4 2025 (-0.6%), with January 2025 production declining 1.8% on a three-month rolling basis. This suggests structural competitiveness issues — including currency volatility, skills shortages, and regulatory burden — that extend well beyond energy supply.
Eskom's turnaround is not yet irreversible. The winter 2025 outlook depends on unplanned outages staying below 13,000 MW. South Africa's aging coal fleet means that a single major unit failure at a base-load station like Medupi or Kusile could reintroduce load shedding, rapidly unwinding sentiment gains and re-establishing the risk premium that has only recently begun to dissipate.
Global commodity cycle exposure. South Africa's mining-heavy economy and JSE remain highly sensitive to global commodity demand, particularly from China. A sharp slowdown in Chinese industrial activity would weigh on PGM, iron ore, and coal prices regardless of domestic electricity improvements.
Investment Thesis
The end of load shedding is the most significant positive structural shift in the South African economy in a decade. It removes a direct cost burden across every sector, improves consumer and business confidence, and unlocks a GDP growth tailwind of 0.6 to potentially over 1 percentage point annually.
The biggest beneficiaries are domestic-facing sectors: retailers, REITs, and banks. These sectors suffered the most direct operational impact from load shedding and stand to gain the most from its cessation. Mining benefits from lower energy costs and improved production stability but remains structurally capped by Transnet logistics failures. Renewables represent a longer-term structural opportunity as South Africa's energy mix irreversibly diversifies away from coal dependence.
For investors, the key question is how much of this improvement is already priced in. JSE valuations have recovered from crisis lows, but relative to the magnitude of the structural shift underway, many domestic names still trade at meaningful discounts to their historical multiples. The FATF grey list exit and GNU governance improvement provide additional catalysts that the market is still in the process of fully digesting.
South Africa is not yet a high-growth story. But it is a normalization story — and for a market that has been systematically penalized by an energy risk premium for nearly a decade, normalization alone can generate substantial returns.
