Tech Giants and Energy Firms Invest Billions in South Africa Despite Economic Slowdown
Private Sector Drives Investment as Public Projects Decline
While overall investment in South Africa has slowed in 2025, global technology leaders and energy companies continue pouring billions into the country’s infrastructure and digital transformation. According to Nedbank’s latest Capital Expenditure Project Listing, newly announced fixed investment projects declined sharply in the first half of the year, but strategic sectors remain attractive to multinational corporations.
The annualized value of new projects fell to R316.2 billion – nearly half of the R592.2 billion recorded in 2024. However, this still represents significant growth compared to 2023’s R215.3 billion. Notably absent were public sector projects, which dominated investment announcements last year with 83% of total commitments.
Tech Titans Lead the Charge
Meta (parent company of Facebook and Instagram) emerges as the largest private investor in South Africa’s communications infrastructure. Their ambitious Project Waterworth accounts for 75% of the R26.4 billion allocated to transport, storage and communications projects. This global subsea cable system will span 50,000 square meters, connecting strategic regions including the US, India, Brazil and South Africa to support next-generation AI and data infrastructure.
Microsoft follows closely with a R5.4 billion investment in cloud infrastructure expansion, reinforcing South Africa’s position as a growing digital hub. “These commitments demonstrate confidence in South Africa’s potential as a technology gateway to Africa,” noted industry analyst Thando Mkhize.

The energy sector dominates investment activity, accounting for 63% of new private projects. Leading this charge is Earth & Wire’s R40 billion “Energy Fields” initiative – a hybrid renewable project combining 700 MW of wind, 800 MW of solar PV and 400-500 MW of battery storage capacity.
“The momentum reflects continued efforts to tackle South Africa’s energy crisis and move away from coal-fired generation,” Nedbank’s report emphasized. Other significant energy projects include:
- Overberg and Ishwati Emoyeni wind farms (R13bn and R4.9bn respectively)
- Photon Energy’s concentrated solar PV plant with thermal hydrostorage (R11.6bn)
- Khauta solar project (R3.2bn)
Industrial and Manufacturing Investments
Beyond tech and energy, strategic industrial projects continue attracting capital:
- Astron Energy’s R6 billion Cape Town refinery upgrade
- PPC’s R3 billion cement plant expansion in Riebeeck West
- SUISO’s R31.5 billion coal-to-fertilizer facility in Kriel
The fertilizer project particularly stands out, aiming to produce 1.5 million tons annually and reduce import dependence. DRDGOLD also commits R8 billion to expand its Withok tailings facility, while Sasol invests R1 billion in its Twistdraai export coal plant.
Challenges and Future Outlook
Despite these bright spots, Nedbank warns of significant headwinds. Grid capacity constraints and transmission infrastructure limitations threaten to slow renewable energy investments. “Implementation of the National Transmission Development Plan could unlock a new wave of energy investment,” the report suggests, but this remains a medium-term prospect.
Other challenges include:
- Global economic uncertainty and lower commodity prices
- South Africa’s elevated public debt and fiscal constraints
- Slow implementation of government reforms
The bank predicts only a mild investment recovery in 2025, contingent on improved financing conditions and domestic demand. “The private sector remains cautious pending visible progress on large-scale public infrastructure projects in water, energy and logistics,” analysts noted.
Major Investment Projects in South Africa (2025)
| Project Name | Value (R million) | Sector | Type |
|---|---|---|---|
| Energy Fields | 40,000 | Electricity, gas and water | Renewable energy |
| Coal-to-fertiliser and methanol project | 31,500 | Mining and quarrying | Industrial processing |
| Meta Project Waterworth | 20,000 | Telecommunications | Digital infrastructure |
| Overberg Wind Farm | 13,000 | Renewable energy | Wind power |
| Microsoft AI & Cloud Infrastructure | 5,400 | Technology | Digital transformation |
As South Africa navigates economic challenges, these strategic investments by global corporations provide crucial support for key sectors. The concentration in technology and renewable energy suggests where the country’s competitive advantages may lie in the coming decade.
