Africa has five regional power pools. It does not yet have a continental electricity market. The gap between those two realities — and the plan to close it — is one of the most consequential infrastructure stories of the next decade.
The Continental Power Systems Master Plan provides the strategic framework: integrate Africa's regional electricity networks into a single, resilient, scalable grid, enabling power to flow freely across the continent's 54 nations based on where generation is cheapest and demand is highest. The Africa Ten-Year Infrastructure Investment Plan for Cross-Border Interconnectivity (TYIIP), coordinated by the AU Development Agency, translates this vision into a pipeline of specific regional transmission projects to be implemented between 2026 and 2036.
The economic logic is compelling. Countries with surplus renewable capacity — particularly in hydropower-rich Central Africa and solar-abundant North and Southern Africa — could export to deficit markets. Import-dependent nations would gain supply security. Developers of large renewable projects would gain access to larger, more liquid offtake markets, improving project bankability. Electricity prices across the continent could fall.
The Southern African Power Pool (SAPP) is the most advanced model for what continental integration could look like. Its institutional framework, interconnected grid, and functioning electricity market have already enabled cross-border energy trading between South Africa, Zambia, Zimbabwe, Mozambique, and others. The SAPP demonstrates that the model works — it requires replication and expansion, not reinvention.
The barriers are real: political coordination across dozens of sovereign governments, financing for transmission assets that span borders, regulatory harmonisation, and the fundamental challenge that electricity market design requires long-term policy commitment from institutions that often operate on shorter cycles. Without the ability to export surplus power, countries have historically been reluctant to invest in large-scale renewable projects. Interconnection resolves this hesitation.
The ten-year plan is the most concrete attempt yet to move Africa from energy archipelago to energy network. Execution, as always in infrastructure, will be everything.
