The gap between energy demand and supply in Nigeria creates a great hindrance to the country’s sustainable development agenda and the realization of its 2060 net zero emissions. The objective of the study reported in this article was to model the electricity demand and supply using the Nigeria Energy and Emissions Calculator (NEECAL2060) which develops consistent scenarios of energy supply to meet energy demand projections. The choices that lead in this direction vary, reflecting the different resource endowments and starting points across a very diverse Nigerian energy landscape. For Nigeria to use the enormous potential of its energy resources given its drive to match electricity demand with supply, and its vision towards 2060 net zero agenda, the barriers to achieving these must be eliminated through significant investment in R&D, the building of indigenous human and manufacturing capacities and intensification of the on-going economic reform to create an investor-friendly environment.
