Technology Choices, Infrastructure Dynamics, and Electrification in Africa

This chapter examines Africa’s electrification trajectory, revealing a fundamental paradox: between 2015 and 2024, electrification rates increased substantially, while renewable energy shares stagnated, suggesting access expansion increasingly relied on conventional infrastructure despite abundant renewable resources. Drawing on continental data spanning 52 African countries, the analysis demonstrates that Africa possesses extraordinary renewable potential, yet deployment remains marginal. Capital costs for renewable projects exceed developed country levels significantly, while Africa attracts a disproportionately small fraction of global renewable investment relative to its resource endowment. Regional variations prove pronounced: East Africa maintains higher renewable shares, while Ghana achieved a remarkable transformation in its generation mix. Grid infrastructure reveals modest capacity growth despite electrification gains, with transmission losses remaining elevated. Reliability challenges remain severe, exemplified by Nigeria’s multiple grid collapses in 2024 and South Africa’s load-shedding economic impacts. Off-grid solutions provide critical complements, with mini-grid capacity expanding and solar home systems reaching millions through mobile money-enabled pay-as-you-go models. Energy sector investment levels prove insufficient for universal access targets. Achieving Mission 300’s goal of connecting 300 million people by 2030 requires differentiated strategies: grid extension for urban areas, mini-grids for intermediate settlements, and standalone systems for remote populations. The chapter concludes that Africa’s energy transition tensions between development speed and climate sustainability reflect financing gaps and institutional weaknesses rather than technical impossibilities, with policy reforms essential to reconcile electrification imperatives with decarbonization responsibilities.
