SA's Energy Transmission Pivot: How the ITP Could Power a New Industrial Era

The ITP offers a long awaited structural solution to the grid bottleneck that has constrained economic growth, renewable energy investment and electrification for millions of households.

This reform arrives at a time when the country’s energy landscape is already undergoing rapid, organic transformation. 

After Eskom’s financial position deteriorated sharply, its vertically integrated monopoly became unsustainable as the utility could no longer fund or deliver the system expansion required to meet demand, or support the shift toward cleaner energy.

This opened the door to private-sector participation. The Renewable Energy Independent Power Producer Procurement Programme (REIPPPP) became the first proof point that competition, not centralisation, could drive faster, cheaper and more reliable energy investment. 

Private developers built wind and solar plants at globally competitive tariffs, demonstrating that the model works. Subsequent licensing reforms removed size caps for new private generation, enabling mines, manufacturers and municipalities to procure electricity directly and wheel it across the grid. 

South Africa moved almost organically from a rigid single buyer system to a dynamic multi buyer, multi seller market.

However, while new generation capacity surged, building out the transmission network needed to distribute this new electricity lagged.

The grid reached capacity in the regions where South Africa’s best renewable resources are located. 

Without expanding the grid, new investment would simply queue up behind bottlenecks.

In addition to the limited grid capacity, broader energy sector reforms necessitated the creation of the National Transmission Company South Africa (NTCSA), to separate transmission from Eskom’s generation activities, enable independent grid operation, unlock investment in transmission infrastructure, and support the transition to a competitive electricity market.

The government also launched the ITP to attract private capital and expertise into transmission.

South Africa needs more than 14,000km of new transmission lines over the next decade. 

Phase one of the ITP identifies 1,164km of priority 400 kV corridors, representing the most urgent expansion required to unlock renewable capacity and stabilise the national grid. 

Global interest is strong: more than 130 developers, Original Equipment Manufacturers (OEMs), Engineering, Procurement and Construction (EPC) contractors, and financiers responded to government’s market sounding process, signalling deep confidence in the country’s transmission opportunity.

Amendments to the Electricity Regulation Act (ERA) support this model by legally permitting private participation in transmission. Cabinet has affirmed the ITP as a flagship programme, and a clear procurement pipeline is emerging under the leadership of the Department of Electricity & Energy, and National Treasury.

These legislative, institutional and market aligned reforms create the most favourable environment for energy investment seen in South Africa in decades. 

However, reforms alone will not guarantee success. Execution will. Transmission projects face unique obstacles – land acquisition, environmental approvals and wayleave negotiations have historically slowed infrastructure delivery. 

Without fast tracked permitting, the ITP risks delay. Government has openly acknowledged this and committed to centralised, accelerated processes to clear bottlenecks before projects reach market. 

Another major challenge and a significant opportunity is South Africa’s limited supply chain capacity for transmission related manufacturing and EPC services. This is where localisation emerges, not as a burden, but as one of the country’s most compelling economic opportunities.

Beyond the power lines, transmission can become a national industrialisation strategy in its own right. Every kilometre of new transmission requires steel towers, conductors, insulators, foundations, and specialised electrical components. 

With thousands of kilometres planned, the ITP offers the kind of long horizon, high volume demand that can stimulate entire manufacturing ecosystems.

Transmission Manufacturing: With predictable demand, local firms could expand tower fabrication, steel processing, conductor manufacturing and transformer assembly. A stable pipeline, rather than rigid quotas, encouraged Brazil and India to build globally competitive local industries, proving that localisation follows confidence, not compulsion.

Job Creation and Skills Development: Skilled and semi skilled workers are needed at every stage of transmission construction, from foundation casting to tower erection and stringing. Sourcing jobs locally can create economic opportunities, particularly in rural areas where they remain limited. Training programmes, certification pathways and OEM partnerships could place thousands of South Africans into high demand technical roles.

Boosting SMMEs and Local Contractors: Transmission routes require access roads, fencing, security, environmental management, logistics, accommodation camps and various community services. Localisation ensures that the benefits of transmission expansion extend beyond metropolitan centres, opening the door to inclusive broad based participation by local township businesses, rural contractors and community owned enterprises. 

The ITP is more than an engineering programme. It is a national development opportunity with implications for economic growth, electricity affordability, industrialisation, and South Africa’s regional leadership.

By enabling gigawatts of new renewable power to reach the grid, the ITP will reduce reliance on expensive diesel, cut carbon emissions and stabilise supply.

South Africa has the blueprint, the investor appetite, and the institutional foundations. What the country needs now is coordinated, disciplined execution, permitting certainty, procurement transparency, supply chain readiness, and ongoing political commitment.

If government delivers on these fronts, the ITP could become the programme that closes the chapter on loadshedding and opens a new era of energy security, industrial growth and shared prosperity. Get this right and transmission will deliver more than just electrons: it will power South Africa’s future.
