    Abstract

    The quest for reliable and adequate power supply in Nigeria has brought about a surge of interest in renewable energy generation, particularly from wind, solar, hydro and biomass resources including municipal solid waste. Waste-derived energy raises unique interest because of the magnitude of benefits to environmental protection and socio-economic advancement. The successful operation of Waste-to Energy (WtE) facilities in Nigeria requires continuous supply of solid waste and enabling environment amongst other factors. This study conducted a state-level assessment of the WtE potential of municipal solid waste (MSW) in Nigeria. Our findings show that the electricity generation potential for the different states in Nigeria varied from 31 to 205 MW, depending on state's waste generation capacity. The country's annual electricity generation potential from MSW was estimated to be 26,744 GWh/year, with 89% of the states having sufficient generation capacity at minimum regulatory electricity generation requirement of 50 MW. But, based on current realities such as poor collection efficiencies, Nigeria's exploitable WtE capacity from MSW was below 3800 GWh/year, with all the states having less than 50 MW capacity. On-site power generation such as dedicated power station for industrial estates and corporate users can be a feasible form of distributing energy generated from WtE facilities. The outcomes of this study are important in informing the siting of WtE facilities in Nigeria and for enabling policy framework.
