Power, Ports and Pipes

South Africa’s reform story is moving from stabilisation to execution. After years in which energy and logistics constrained growth, early operational gains are beginning to change the investment case.

For investors, this matters because infrastructure is starting to emerge not just as a public policy priority, but as an investable asset class. The opportunity is uneven and execution risk remains high, but the direction is becoming clearer across energy, logistics and water.

The progress is tangible. Eskom’s energy availability factor rose to 65.35% in the year to 31 March 2026, while average unplanned outages fell materially from year-earlier levels.

In logistics, government allocated rail slots to 11 train operating companies across 41 routes and six corridors, while the Transnet National Ports Authority reported stronger vessel traffic through 2025/26.

The BLSA Reform Tracker reinforces that trend, with the reforms completion index up 27% from its March 2024 baseline to 71.75. 

These sentiments were echoed at the 2^nd SA Economic Reforms Conference hosted by Investec, where investors appear increasingly constructive on South Africa’s macroeconomic recovery, supported in part by improved cooperation within the Government of National Unity (GNU).

However, stabilisation is only the first step. The next phase is about converting early gains into execution at scale.

Energy reform has moved furthest. The system has regained a measure of stability, but the more important shift is structural: South Africa is moving from a single-buyer model towards a more competitive, multi-buyer, multi-seller market.

That transition is reshaping the investment landscape. Private capital is now driving new generation capacity, with energy traders and large users emerging as meaningful buyers of power.

By October 2025, more than 16.8 GW of private renewable energy projects had been registered with NERSA, with solar PV dominating additions. Alongside battery storage, that build-out is making the power system more flexible and deepening the role of private investment in generation.

The next bottleneck is transmission. Grid capacity, especially in high-potential renewable regions, is now the main constraint on growth and on the integration of new supply.

According to the DBSA, South Africa requires roughly R440 billion in investment between 2025 and 2034 to expand and modernise the grid and integrate 56 GW of new generation capacity.

For investors, the implication is clear: generation led the first wave, but transmission is likely to define the next one. The constraint is no longer appetite for capital, but the pace of project execution, permitting and funding design.

Reliable, more competitively priced electricity should improve the economics of energy-intensive sectors, particularly mining and processing linked to the global energy transition. In that sense, energy reform is no longer only about security of supply; it is increasingly central to the next phase of industrialisation.

If energy is the first leg of the reform story, logistics is the next. South Africa’s growth model is deeply trade-exposed, which means inefficient rail and port infrastructure acts as a direct brake on exports, investment and output.

The underlying problem is familiar: deteriorated freight rail, ageing port infrastructure and persistent corridor congestion. In an open economy, those bottlenecks do not stay local for long; they quickly become a national growth constraint.

Reform in logistics is lagging energy, but the opportunity may be just as significant. Opening rail and port infrastructure to private participation is starting to move from policy design to implementation.

With broader private sector participation entering the system, more operators and greater competition should improve utilisation, lower costs and raise service quality over time.

Port concessions and other partnership models point in the same direction. But investor enthusiasm alone will not be enough.

The scale of the requirement is substantial. Transnet’s funding need is estimated at about R200 billion, while government has committed more than R1 trillion to public infrastructure over the next three years.

The key challenge is bankability: investors need clarity on tariffs, access rights, risk allocation and the regulatory framework before capital can be deployed at scale.

Designing bankable projects is proving to be one of the biggest challenges. Investors require clarity on tariffs, access rights, and regulatory frameworks before committing capital. Without predictable rules of the game, even the most attractive assets remain out of reach.

That is why long-term concession models are gaining traction. They offer a clearer route to operational accountability and better alignment between performance incentives and asset value.

For investors, logistics is a turnaround opportunity with real upside, but returns will depend on whether projects are structured in a way that is both operationally viable and financially bankable.

While energy and logistics have been the major focus in recent years, water is emerging as the next systemic macroeconomic risk.

Water underpins agriculture, mining, industrial production and household resilience, which means system failure carries wide economic costs.

The core weakness is not bulk supply alone, but distribution. Municipal delivery systems are under strain from weak governance, poor maintenance, financial distress and ageing infrastructure.

The investment need is enormous. DBSA-backed research estimates that South Africa requires about R7.16 trillion in water infrastructure investment through to 2050, or roughly R256 billion a year, to secure future water supply and sanitation outcomes.

Private participation has been limited by below-cost tariffs, weak utility creditworthiness, political resistance and regulatory uncertainty.

Even so, metros and selected secondary cities could support meaningful investment if projects are ring-fenced, tariffs become more cost-reflective and enforcement improves.

A practical starting point is reducing non-revenue water losses, one of the clearest opportunities to improve both system efficiency and project viability.

South Africa has moved beyond pure crisis management, but it has not yet reached escape velocity. The investment case in infrastructure is real, particularly where reform momentum, regulatory clarity and project economics align.

The next phase will be defined less by policy intent than by delivery: whether the country can convert stabilisation into scale across power, logistics and water.
