Africa Power Transmission Infrastructure Investment Gap Market Growing at CAGR 11.4% to Reach USD 20,056 Million by 2032

Africa’s power transmission infrastructure investment gap market is going through a structural shift, moving away from slow, utility-only grid spending toward independent transmission projects, availability-payment concessions, HVDC links and cross-border interconnectors, as governments race to connect new solar, wind, hydro and gas plants to load centres that national grids cannot yet reach.

According to Market Research Outlook’s latest research report, the “Africa Power Transmission Infrastructure Investment Gap Market“ is expected to grow from USD 9,420 million in 2025 to USD 20,056 million by 2032, at a CAGR of 11.4%, supported by large renewable pipelines waiting for grid capacity, weak and outage-prone national networks, new private financing models for transmission, and regional power pool interconnection programs.

Transmission has become the main bottleneck in Africa’s power sector, with generation projects now waiting years for lines and substations, and governments shifting from asking how to build plants to asking how to move the power.

What is changing is not just the scale, but the nature of investment. Utilities, development finance institutions, infrastructure funds and international grid companies now view transmission as a bankable asset class, backed by availability payments, regulated returns and long concessions rather than one-off public budgets.

This shift is being reinforced by Eskom’s plan for 14,500 km of new high-voltage lines by 2034, Kenya’s first private transmission PPP worth USD 311 million, the 3,000 MW Egypt-Saudi Arabia HVDC link, and 600 million Africans still living without electricity. As a result, transmission is now treated as the priority investment that unlocks generation, trade and electrification across the continent.

The growth of the market is closely linked to the size of national grid plans. In South Africa, Eskom’s Transmission Development Plan earmarks R112 billion over five years and targets 5,043 km of new lines by the 2029 financial year to connect 56 GW of new generation expected by 2034. Equipment and EPC suppliers such as Hitachi Energy, Siemens Energy, GE Vernova, Larsen & Toubro, KEC International and China Electric Power Equipment and Technology are expanding African order books for lines, substations and HVDC converter stations, while Africa50 and Power Grid Corporation of India are bringing private capital into Kenya’s grid.

At the same time, governments across South Africa, Nigeria, Kenya, Egypt, Ethiopia and Tanzania are opening transmission to private investors, supported by South Africa’s Independent Transmission Projects programme, Nigeria’s Electricity Act 2023, the World Bank and African Development Bank’s Mission 300 program and the Africa Single Electricity Market, creating steady upstream demand for overhead lines, substations, transformers, HVDC links and grid control systems across Africa’s power transmission infrastructure investment gap market.

Project development is increasingly focused on higher-capacity infrastructure, including 400 kV and 765 kV overhead lines for long-distance renewable evacuation, HVDC links for cross-border trade, gas-insulated substations for dense urban areas, digital substations with remote protection, and SCADA and energy management systems for power pool coordination. As a result, spending is gradually shifting toward large, multi-country corridors that move bulk power across regions, supporting higher value per kilometre and better utilisation of generation assets.

Despite this strong momentum, the market continues to face challenges. Weak utility finances and high sovereign risk, slow land acquisition and right-of-way approvals, and long lead times for transformers, conductors and HVDC equipment remain key concerns. Vandalism and theft of towers and cables add further cost and outage risk. However, availability-payment PPPs, blended finance from development banks, regional procurement and growing local manufacturing of towers and conductors are gradually easing these pressures over time.

Looking ahead, opportunities are emerging across independent transmission projects in South Africa, PPP concessions in Kenya, Uganda and Zambia, renewable evacuation corridors in North Africa, and interconnectors linking the Eastern, Southern and West African power pools. Increasing collaboration between utilities, development finance institutions, infrastructure funds, EPC contractors and equipment majors is also accelerating project preparation, financing speed and cost control, positioning the market for sustained, value-driven and inclusive growth through 2032.
