- PwC Forecasts 77 Per Cent Rise in Infrastructure Investment Across Four African Economies, Including Ghana
Annual infrastructure spending across Ghana, Kenya, Nigeria and South Africa is projected to reach US$96 billion by 2050, but the real test will be whether the increase produces competitive economies or merely a larger portfolio of expensive projects.
PwC’s Global Infrastructure Outlook forecasts that combined annual expenditure in the four countries will rise by 77 per cent from US$54 billion in 2024. Africa is expected to record the fastest infrastructure-spending growth of any region over the next 25 years, driven principally by population growth, urbanisation and large unmet development needs.
The projection offers Ghana an opportunity, but not a guarantee. Infrastructure spending becomes economically valuable only when roads lower transport costs, electricity supports production, water systems improve public health and digital networks raise productivity. Money committed to badly selected, delayed or poorly maintained projects can increase debt without creating the capacity required to repay it.
PwC expects Africa to add more than 800 million urban residents by 2050, while the number of megacities triples. Transport will remain the largest infrastructure sector, with spending projected to more than double as trade corridors expand. Agriculture and resources are expected to rank second and third respectively.
For Ghana, this demographic transition will intensify pressure on already stretched urban systems. Accra, Kumasi, Tamale and other growing centres will require housing, drainage, sanitation, mass transport, reliable electricity and digitally enabled public services. Failure to build ahead of population growth could leave the country spending more simply to manage congestion, flooding and service breakdowns.
The most important implication is that infrastructure can no longer be planned as isolated projects. A port expansion delivers limited value if access roads and rail links are inadequate. A data centre cannot operate competitively without reliable power, fibre connectivity, water and cybersecurity. Irrigation investment achieves little when farmers lack storage, processing facilities and dependable routes to markets.
PwC consequently urges governments to move from sectoral silos towards integrated systems. It warns that concentrating capital in power or digital infrastructure without corresponding improvements in transport and water can create bottlenecks that constrain growth and investment returns.
This systems approach is particularly relevant to Ghana’s ambition to develop manufacturing, agro-processing, mineral beneficiation and digital services. Industrial policy cannot succeed through tax incentives alone. Investors assess the full cost of operating: electricity reliability, port efficiency, inland transport, land access, communications, skills and regulatory predictability. Weakness in one component can neutralise improvements elsewhere.
Financing will be equally decisive. Ghana’s fiscal space remains constrained, while infrastructure projects typically require large upfront investment and generate returns over decades. The state cannot fund the coming build-out solely through annual budgets or additional sovereign borrowing without risking renewed debt pressure.
Private capital, pension funds, development institutions, sovereign wealth funds and specialist infrastructure investors will therefore have to play a greater role. PwC proposes risk-sharing structures, stronger public-private partnerships and capital recycling, under which governments sell or lease mature assets and reinvest the proceeds in new infrastructure.
Such mechanisms must be treated cautiously. Private participation does not remove costs; it changes how projects are financed, operated and paid for. Poorly negotiated agreements can leave the public carrying risks while investors retain guaranteed returns. Ghana will need transparent procurement, credible demand forecasts, fair risk allocation and strong regulatory supervision to prevent partnerships becoming hidden public liabilities.
Projects must also become bankable before officials advertise them to investors. This requires completed feasibility studies, secured land, clear revenue models, environmental approvals, community engagement and protection from arbitrary policy reversals. Investors price uncertainty, and every delay caused by inconsistent regulation raises the eventual cost to users or taxpayers.
PwC recommends stable regulatory environments and independent institutions capable of making long-term infrastructure decisions across political cycles. That proposal addresses one of Ghana’s persistent weaknesses: projects are sometimes redesigned, abandoned or reprioritised when governments change, even after significant public resources have been committed.
A credible national infrastructure pipeline should therefore rank projects by economic and social returns rather than political visibility. Parliament and the public should be able to see estimated costs, funding sources, delivery timelines and expected outcomes. Independent assessment would make it harder to commence projects without realistic financing or maintenance plans.
Maintenance deserves the same attention as construction. Ghana’s infrastructure debate often celebrates new roads, schools and hospitals while allocating insufficient resources to preserve existing assets. Deferred maintenance may create temporary budget savings, but it shortens asset life and ultimately requires more expensive reconstruction.
Technology could improve delivery. PwC identifies digital twins, modular construction, artificial intelligence-enabled controls and outcome-based contracting as tools for reducing delays and improving performance. Ghana can use digital procurement and project-monitoring platforms to compare expenditure with physical progress, identify cost overruns early and strengthen public accountability.
The wider global backdrop is formidable. PwC forecasts cumulative infrastructure investment of US$151.1 trillion through 2050, with annual global spending increasing from US$4.4 trillion in 2024 to US$6.9 trillion. Transport and power will account for about half of this expenditure, while data centres, electrification and intelligent networks reshape capital allocation.
Ghana will consequently compete with emerging economies worldwide for finance, engineering expertise and construction capacity. Its advantage will not be need alone; every developing country can present a long list of deficits. Capital will favour jurisdictions offering policy stability, commercially sound projects and credible execution.
The US$96 billion forecast should therefore be read as a measure of potential demand, not money already secured. The number combines four countries and does not disclose Ghana’s individual share. It also describes annual spending in 2050 rather than cumulative financing available today.
Ghana’s objective must be to convert its portion of that prospective investment into lower production costs, stronger trade links, better services and durable employment. If planning remains fragmented and projects are selected for short-term political reward, higher spending may produce little transformation.
Infrastructure is the expression of economic strategy. Ghana’s choices will determine whether cities become engines of productivity or centres of congestion. PwC’s forecast shows more capital will be required; Ghana must prove it can convert that capital into durable assets that expand opportunity.
