<p>This research explores the transformative potential of integrated energy solutions to advance sustainable development in Nigeria, employing a comprehensive multi-faceted assessment model. It critically examines the nation’s energy landscape, highlighting the discrepancy between the available energy sources and the current energy utilization giving an insight to how the bulk of the Nigerian energy market remains highly untapped, underutilized and crippled by inefficiencies. The study presents the use of integrated energy as it presents opportunities for diversification and strategies to enhance energy security, the study identifies economic and environmental benefits of integrated energy systems. However, challenges may persist in the implementation of integrated energy systems such as, regulatory deficiencies, financial barriers, technological limitations, and stakeholder collaboration gaps. Showcasing some case studies like China’s integrated energy management system (IEMS) etc., the study proposes targeted policy recommendations focusing on robust regulatory reforms, technological innovation, and inclusive stakeholder engagement. The findings underscore the capacity of integrated energy systems to improve Nigeria’s energy access, reliability, and efficiency in the power sector, and the potential for the sector to help foster economic growth, reducing poverty, and advancing environmental sustainability. This study advocates for a holistic approach to achieve a resilient and sustainable energy future for Nigeria and offers a framework for similar transitions in other developing nations.</p>
