Leveraging the Energy Access Explorer for Geospatial Mapping of Universal Electricity Access in Nigeria

This analysis evaluated electrification pathways in Nigeria using spatial and socio-economic indicators using Energy Access Explorer. Areas with high population density, proximity to markets, healthcare facilities, and closeness to distribution lines, particularly in Rivers, Lagos, Ebonyi, Akwa Ibom, Federal Capital Territory and Kano located in southern Nigeria, were identified as suitable for on-grid electrification, representing regions with high grid connectivity and established electricity demand. In contrast, underserved communities with low population density and high solar potential were prioritized for off-grid solar mini-grid development. Grid-connected areas were excluded through spatial filtering to focus on high-impact, unserved locations. Findings indicate that approximately 122.5 million Nigerians are connected to the national electricity grid. Northern states such as Katsina, Yobe, Kano, Jigawa, Bauchi, Adamawa, Sokoto, Borno, and Zamfara exhibit the highest solar irradiance, with many potential solar sites located beyond 2 km from existing grid lines, making decentralized solar systems ideal for powering rural markets and healthcare centers.
