The lack of access to clean and affordable energy supply is one of the factors affecting people's socioeconomic life and well-being in several local communities in Nigeria. This has birthed several other issues such as a lack of potable water, good healthcare service, etc. Therefore, this paper presents the techno-economic design and analysis of wind power-based water pumping systems, considering the average daily wind speed of a location in Ikeja, Lagos, Nigeria. The wind potential was modelled using a two-parameter Weibull distribution to determine its viability for water pumping in the location. Five 25-kW, pitch-controlled wind turbines (WT1 - WT5) from different manufacturers with dissimilar characteristics were examined at varying hub heights. The annual energy generated, the cost of energy (COE) and the cost/m³ of water produced (Cunit) were then evaluated. The results indicate that WT3 has the least COE ranging from $0.03/kWh to $0.13/kWh and Cunit ranges from $0.003/m³ to $0.012/m³ for hub-heights of 10m to 50m, while WT5 has the highest COE ranging from $0.011/kWh to $0.64/kWh and Cunit ranges from $0.011/m³ to $0.063/m³ for hub-heights of 10m to 50m. The results further reveal that the proposed system is more economically viable than the public utility system. [ABSTRACT FROM AUTHOR]
