Techno-Economic Analysis of Off-Grid Hybrid PV-Diesel-Battery System in Katsina State, Nigeria

Abstract

Continuous burning of fossil fuel has a great impact on the environment. Thus, moving toward renewable energy system or hybridization of alternative energy systems can reduce the emission of hazardous gases produced by the fossil fuels. This paper presents a techno-economic analysis of hybrid PV/diesel and battery system configuration of five (5) Houses at Barhim Quarters, Katsina, Nigeria. HOMER optimization software was used for the techno-economic analysis. This paper shows how a meaningful amount of CO2 can be reduce and the impact of PV penetration by the optimized hybrid PV/diesel system configuration. Having compared the configurations such as the PV-diesel-battery, PV-diesel without battery, Standalone diesel and standalone PV system based with $0.434/kW, $0.645/kW, $0.721/kW and $0.908/kW respectively as their cost of energy. Considering the Net present costs, cost of energy, CO2 emission, excess of electricity generated and renewable penetration, a PV-diesel-battery Hybrid Power System (HPS) was proposed for the area under focus.
