Mechanised agriculture has the potential to supply Nigeria with the export needs, it requires to diversify and close its GDP gap. This potential can be actualised if the rural agricultural farmers adopted the use of mechanised irrigation farming techniques. The wind is widespread in Nigeria and wind-powered irrigation system is a clean and decentralised alternative for providing rural communities with electricity for meeting domestic and irrigation farming power needs in a sustainable way. In this study, the technical, financial and economic viability of supplying 10 hectares of land with irrigation water for rice farming over two seasons using 10, 30 and 55 kW wind turbine powered irrigation pumping system, with Ada-Rice in Opanda, Enugu State Nigeria as a case study. First, four different kinds of basin irrigation options were designed and irrigation water demand estimated for each option. Then the wind-powered system was sized based on the head of water and horsepower (HP) required to abstract and supply irrigation water demand The cost of the three different wind turbines and four irrigation schemes were calculated and compared using the economic and financial net present value (NPV) as metrics. It was found that the wind turbines can supply the irrigation water requirement of paddy rice in the study area. The economic analysis result showed that all the analysed wind turbines have economic benefits in the studied location but none is financially viable from the commercial financial investment perspective except over 70% subsidy is given on total investment cost. The 10 kW is the most suitable, in terms of NPV and capacity factor in the study location.
