ABSTRACT
The main aim of this study is to examine economic and technological feasibility of energy systems that involves wind, PV, and diesel systems for rural communities in Nigeria. The study purposed to examine the sources of energy available in Kuda village in Ngazai community, determine the load profile of Kuda village, design renewable energy systems for Kuda village, and compare the economic feasibility of the energy sources using NPC IRR and COE. A case study was adopted as the research design. The homer simulation was used for the design of the wind/PV/diesel system of the study. The assessment methods used for determining the economic feasibility of the systems are COE, NPC, and IRR.
It was found out that the diesel system has the lowest initial cost of capital, high fuel cost, high O & M, highest IRR, lowest NPC, and lowest COE. The PV system has the highest initial cost of capital, no fuel cost, moderate operation and maintenance cost, lowest IRR and NPC, and the highest COE. The wind system has a high initial cost of capital, no fuel cost, moderately high O&M cost, moderately high IRR and NPC, and moderate COE. It was thus recommended that the diesel generator system is the best for the Nganzai community based on the cost-effectiveness of the diesel generator system with the lowest COE, the lowest NPC, highest IRR, and the lowest capital cost.
