An Economic Evaluation of a Small-Scale Wood-Fired Gasifier for Decentralized Power Generation in Nigeria

Authors: Akhator PE, Obanor AI, Sadjere EG


This study presents an economic evaluation of a small-scale biomass gasifier power plant (BGPP). The major aim was to evaluate the economics of coupling a small-scale wood-fired open-core downdraft gasifier to an internal combustion engine (ICE) for electricity generation using the levelized cost of electricity (LCOE). The gasifier was made using locally sourced materials in a workshop in Benin City, Edo State, Nigeria. The gasoline generator was obtained from a local market in Benin City. Results from the study show that the LCOE of the gasifier power plant was approximately N12.78/kWhel (electrical energy). This generation cost was much lower than that (N82.81324/kWhel) of generator fuelled with gasoline commonly utilized for electricity generation in Nigeria. This generation cost was also lower than the electricity tariff in some regions established by the Nigerian government in 2019. This indicates that the BGPP presents a more profitable alternative than gasoline for electricity generation in Nigeria in the absence of grid electricity. Hence, development of such power projects should be encouraged in Nigeria to ease the present electricity crisis in Nigeria, especially in the rural areas.
