Abstract
This research aims to analyze the techno-economic viability of an off-grid hybrid power system for rural areas in Nigeria, specifically in the Uzere community of Delta State, where access to reliable and sustainable power supply from the national grid remains a significant challenge. This study employed both survey and simulation modeling methodologies using HOMER Pro software application. The existing 500kW Independent thermal station was evaluated alongside solar and power storage sources. The results revealed that relying solely on thermal generation, without incorporating alternative energy sources, resulted in a Levelized Cost of Energy (LCOE) of ₦63.65/kWh and a Net Present Cost (NPC) of ₦54.9 billion. This outcome was primarily attributed to the low-priced gas incentives offered by oil and gas-producing companies and operators. The optimized hybrid system yielded an LCOE of ₦120.48/kWh and NPC of ₦30.9 billion, reducing gas emissions by 30%. The national grid tariff of ₦225.00/kWh was significantly higher. The study recommends collaborative policy frameworks, adequate funding, and gas incentives between government agencies and oil-producing companies to promote off-grid hybrid power systems in rural communities, ensuring uninterrupted and sustainable power supply for social and economic growth.
