Energy supply and public sector performance in Calabar municipality, Cross River State- Nigeria

This study examined the influence of energy supply on public service delivery in Calabar Municipality Local Government Area of Cross River State. The study was driven by persistent concerns over unstable electricity and its implications for the effectiveness of essential public services. Anchored on Systems Theory and Energy Ladder Theory, the research explains how energy functions as a central input that sustains interconnected service systems and improves institutional performance as access to modern energy increases. A quantitative survey design was adopted and data were collected from residents and users of public institutions across the municipality. Findings revealed that stable electricity supply significantly enhances healthcare delivery, improves teaching and learning activities, supports water pumping and distribution, and strengthens administrative efficiency. The study further showed that irregular power supply causes delays in medical services, limits the use of ICT facilities in schools, increases dependence on generators, raises operational costs, and weakens sanitation services. These results highlight the strategic importance of electricity as a critical driver of public sector productivity and community wellbeing. The study concludes that improving energy stability is essential for strengthening service delivery and promoting sustainable development. It recommends sustained investment in power infrastructure, adoption of alternative energy sources, and improved coordination between energy providers and public institutions.
