Rural and arid regions often face significant challenges in agricultural electrification due to lack of reliable grid access and high dependence on diesel generators. These regions require sustainable, cost-effective, and reliable energy solutions that can meet irrigation and other agricultural load demands under variable climatic conditions This study aims to design and optimize a PV-Wind-Battery hybrid energy system to provide continuous, off grid electricity for agricultural applications in arid regions, ensuring technical reliability, economic feasibility, and environmental sustainability. System modelling and optimization were conducted using HOMER Pro software, incorporating techno-economic evaluation, sensitivity analysis under variable solar and wind resources, and assessment of environmental impacts. The proposed hybrid system comprises 180 kW of Photovoltaic (PV) panels, wind turbines 140 kW total, and a Battery Energy Storage System 1382.4 kWh. The PV system generates 317,950 kWh annually with an average performance ratio of 0.772, while wind turbines produce 793,034 kWh per year. The battery ensures stable power supply with 16.8 hours autonomy and a lifetime throughput of 944,345 kWh. Sensitivity analysis shows system resilience under 10% reductions in solar irradiance, wind availability, or both, with minor changes in Net Present Cost (NPC) and Levelized Cost of Electricity (LCOE). The hybrid system reduces fuel consumption and achieves a CO 2 mitigation of approximately 922.117 t/year, demonstrating environmental benefits. The optimized PV-Wind-Battery hybrid system provides a reliable, cost-effective, and sustainable solution for agricultural electrification in arid regions. Its complementary renewable sources and energy storage ensure continuous supply and resilience against climatic variability. The findings offer guidance for researchers and engineers planning off-grid renewable energy systems, highlighting the potential for replicable, low-carbon, and economically viable agricultural electrification solutions.
