This study was conducted to evaluate the techno-economic viability of an optimized hybrid solar photovoltaic (PV) and pumped hydro energy system for off-grid applications in Nigeria. The research employed a quantitative approach, gathering data to model the energy generation and performance characteristics of the hybrid system across selected northern and southern states of Nigeria. The study focused on key parameters such as solar irradiance, water head, and altitude, utilizing them to simulate the system’s daily energy output, operational costs, and financial metrics, including Levelized Cost of Energy (LCOE), Net Present Value (NPV), and Internal Rate of Return (IRR). The results showed that hydro power was the dominant source of daily energy, while solar PV contributed regionally based on irradiance levels, demonstrating the hybrid system's adaptability to local conditions. Sensitivity analysis revealed that fluctuations in solar input, equipment costs, and energy tariffs could impact system viability but did not undermine its overall cost-effectiveness. The system also met the Nigerian Electricity Regulatory Commission (NERC) Mini-Grid Regulation standards for voltage stability and system uptime. The study concluded that such hybrid systems have strong potential for addressing Nigeria’s energy access challenges, particularly in rural and semi-urban areas. It recommended the adoption of region-specific hybrid systems and policy incentives to enhance energy security and sustainability in Nigeria’s off-grid communities.
