Africa’s electricity grid is struggling to keep pace with rapidly expanding generation capacity — and without urgent investment in transmission, much of the continent’s renewable energy pipeline risks being stranded.
According to a press release ahead of African Energy Week (AEW) 2026 in Cape Town, Africa’s electricity demand is projected to nearly double to 2,291 TWh by 2050, requiring an estimated $30 billion in transmission and grid infrastructure investment to unlock and integrate new generation capacity.
The scale of the challenge is visible across the continent. In Nigeria, repeated nationwide grid collapses — including incidents recorded as recently as February 2026 — underscore the fragility of aging transmission infrastructure.
In East Africa, tower failures along the 428-kilometre Loiyangalani-Suswa line temporarily stranded output from Lake Turkana Wind Power, Africa’s largest wind installation. Across North Africa, electricity consumption is expected to rise by around 50% by 2035, driven by urbanisation, desalination projects and rising temperatures.
The release, from the African Energy Chamber, warned that the growing imbalance between generation and grid capacity is driving greater attention toward system-wide planning and regional market design — themes that will anchor the newly launched Power Africa Today conference, which will bring together policymakers, utilities, investors and developers in Cape Town from October 12 to 16.
Some markets are already moving. Zimbabwe opened its electricity sector to full private participation in 2025, targeting $9 billion in investment. South Africa is advancing plans for 14,500 kilometres of new transmission lines and 133,000 MVA of transformer capacity by 2034. Kenya has introduced open-access regulations enabling independent power producers to sell electricity directly to multiple buyers.
Regional integration is also progressing slightly. The World Bank’s RETRADE SAPP programme is deploying $12 million across 12 Southern African member states. The Ethiopia-Kenya-Tanzania Electricity Highway is operating on a trial basis at up to 2,000 MW. West Africa’s Power Pool permanent synchronisation is expected in 2026.
The release stressed that infrastructure alone is insufficient. Investors continue to cite the absence of standardised offtake structures, creditworthy counterparties and cross-border payment guarantees as major barriers.
AUDA-NEPAD estimates that Africa requires approximately $30 billion in additional investment to complete priority transmission corridors and establish three fully interconnected regional trading blocs by 2030.
“Interconnected electricity markets are the foundation of Africa’s industrial future,” NJ Ayuk, Executive Chairman of the African Energy Chamber, noted.
Ayuk added, “The question at Africa Energy Week is not whether integration is possible — the evidence is already there. The question is which regulatory frameworks and financial structures will get projects to financial close, and which markets will be ready when capital is looking to move.”
