# South Africa Infrastructure: Investment Risk, Policy Gaps, and Ground-Level Reality

South Africa's infrastructure crisis is no longer a projection — it is a current operating condition. Power cuts, collapsing ports, and deteriorating road networks have measurable effects on GDP growth, foreign direct investment, and day-to-day business viability. Understanding where the failures are concentrated, what government has committed to, and what those commitments are actually worth is essential for anyone making decisions in or about the country.

The Scale of the Problem

South Africa's infrastructure deficit has accumulated over roughly two decades of underinvestment, governance failures at state-owned enterprises, and chronic budget overruns on the projects that were funded.

Key figures that define the current situation:

• The National Treasury estimated South Africa's infrastructure backlog at over R4 trillion in 2024, with no credible updated figure suggesting improvement by 2026.
• Eskom's total debt stood at approximately R420 billion before the partial restructuring in 2023–2024, and operational reliability has not recovered to 2007 levels.
• Transnet handled roughly 174 million tonnes of freight in 2022, down from a peak of 230 million tonnes, a decline directly linked to rail infrastructure decay and equipment theft.
• The City of Johannesburg loses an estimated 30–40% of its water supply to leaks and illegal connections annually.

These are not background conditions. They are operational constraints that affect every sector of the economy.

Energy Infrastructure: Eskom, Embedded Generation, and What Has Actually Changed

Load shedding reached Stage 6 in 2022 and remained structurally embedded through 2023. By 2025–2026 the frequency of rotational cuts declined, but this reflects reduced industrial demand and increased embedded generation — not a repaired grid.

The practical implication: businesses operating without their own backup power remain exposed. The grid has not been fixed — demand has shifted around it.

What the Electricity Regulation Amendment Act changed:

• It enabled a competitive electricity market in principle
• It authorised third-party access to the national transmission grid
• It created the framework for the National Transmission Company of South Africa (NTCSA)

What it has not yet done is produce functioning wheeling at scale. Bilateral power purchase agreements between private generators and off-takers remain administratively complex. Municipal bylaws in several metros still create barriers that national legislation has not overridden.

Transport Infrastructure: Ports, Rail, and Roads

Transnet's operational performance has become a sovereign risk issue. International commodity traders, mining houses, and agricultural exporters have all publicly cited port and rail failures as direct revenue constraints.

Rail:

• The iron ore export line (Sishen–Saldanha) operated well below nameplate capacity through 2024–2025.
• Coal export volumes via Richards Bay Coal Terminal declined from a peak of around 91 million tonnes to under 60 million tonnes in recent years, limiting royalty revenues.
• The general freight rail network saw cable and equipment theft exceed R1 billion annually.

Ports:

• The Durban port container terminal consistently ranked among the least efficient in major global port performance indices.
• Transnet's capital expenditure plan announced in 2024 identified a need for R100 billion in investment over five years — against a balance sheet that cannot support that level of independent borrowing.

Roads:

• The South African National Roads Agency (SANRAL) manages approximately 22,000 km of national roads.
• Provincial and municipal road networks — which are far larger — are funded through provincial equitable share allocations that have declined in real terms.
• The SA Institution of Civil Engineering's Infrastructure Report Card has rated the national road network as declining, with provincial roads rated poor to very poor.

Private logistics operators have responded by moving volume to road, which increases costs and accelerates road surface deterioration — a self-reinforcing negative cycle.

Water and Sanitation: The Next Infrastructure Crisis

Energy receives most media and political attention, but water infrastructure failure poses an equal long-term risk.

• South Africa is a water-scarce country. Mean annual rainfall is approximately 465mm against a global average of around 860mm.
• The Department of Water and Sanitation's own audits identified hundreds of water treatment works and wastewater treatment plants as dysfunctional or in critical condition.
• Acid mine drainage from abandoned mines in Gauteng and Mpumalanga represents both an infrastructure liability and an environmental risk that has not been resolved after more than a decade of committee reports.
• The Vaal Dam system, which supplies Gauteng, has faced declining inflows linked to catchment degradation and increased upstream abstraction.

Several secondary cities — Gqeberha (Port Elizabeth) being the most documented case — have experienced extended periods of near-complete municipal water failure. The causes are consistent: deferred maintenance, collapsed revenue collection, and management failure at the municipal level.

What the Government Has Committed To

The Infrastructure South Africa (ISA) office, established under the Department of Public Works and Infrastructure, was tasked with unblocking projects across sectors. The Strategic Integrated Projects (SIPs) framework designated a pipeline of projects intended to move at accelerated pace.

Results as of 2026 have been mixed:

The gap between commitment and delivery reflects a structural issue: South Africa has reasonable planning institutions but weak implementation capacity at both national and subnational levels.

Private Sector Participation: Where It Works and Where It Doesn't

The embedded generation market has demonstrated that private capital will move quickly when regulation permits it. Solar PV installations in the commercial and industrial segment grew rapidly once the Schedule 2 threshold was raised and then removed for registration purposes.

Where private participation has not worked:

• Bulk water infrastructure requires long concession periods and state credit support that policy has not provided clearly.
• Rail concessions have been discussed for over a decade without a credible procurement process reaching financial close.
• Municipal-level public-private partnerships are hampered by the Municipal Finance Management Act's complexity and municipal financial distress.

The legal and regulatory environment for infrastructure PPPs includes:

• The MFMA (Municipal Finance Management Act)
• PFMA (Public Finance Management Act) regulations on PPPs
• National Treasury PPP unit guidelines
• Sector-specific legislation (Water Services Act, NLTA for transport, ERA for electricity)

Navigating this framework requires specialist legal and financial advisory capacity that smaller municipalities cannot afford — creating a further barrier at the local level where infrastructure gaps are worst.

Land and Property Rights Intersecting with Infrastructure

Infrastructure project delivery in South Africa intersects with land policy in ways that create specific risks not present in most comparable markets.

Expropriation legislation — specifically the Expropriation Act signed in January 2025 — introduced provisions for expropriation of land with nil compensation in defined circumstances. For infrastructure projects:

• Rights of way and servitude acquisition could be affected by the new expropriation framework.
• Uncertainty around compensation methodology increases risk pricing for long-duration infrastructure assets.
• Agricultural land intersecting with water or energy infrastructure corridors adds complexity.

This is not a hypothetical risk. Several IPP developers have flagged land access and community rights issues as material delays to project timelines.
