Abstract
{ "background": "Persistent energy poverty and unreliable centralised grid supply constrain economic activity in many African regions. Decentralised renewable energy mini-grids are promoted as a sustainable solution, yet qualitative evidence linking their operation directly to SME financial performance in complex, resource-rich environments like the Niger Delta remains sparse.", "purpose and objectives": "This study explores the perceived relationship between decentralised renewable mini-grids and SME profitability in the Niger Delta, aiming to understand the mechanisms through which energy access influences business outcomes from the entrepreneurs' perspective.", "methodology": "A qualitative, exploratory design was employed. Data were collected via in-depth, semi-structured interviews with SME owners and managers across multiple sectors, supplemented by focus group discussions. A purposive sampling strategy ensured participants were all connected to operational solar-hybrid mini-grids. Thematic analysis was conducted on the transcribed data.", "findings": "A dominant theme was that enhanced energy reliability, rather than mere access, was the critical driver of increased profitability. Specifically, over three-quarters of participants reported a reduction in operational costs by eliminating expenditure on diesel generators. A concrete result was that several manufacturing SMEs extended operating hours by an average of 35%, directly increasing production volume and revenue.", "conclusion": "The study concludes that decentralised mini-grids can significantly enhance SME profitability in the Niger Delta, primarily by providing a more reliable and cost-effective power source that enables operational expansion and reduces energy-related overheads.", "recommendations": "Policymakers should integrate dedicated, reliable energy access for SMEs into regional development plans. Mini-grid developers should design tariff structures that support productive use and offer tailored technical support to business clients.", "key words": "decentralised energy, mini-grids, SME profitability, renewable energy, Niger Delta, qualitative research", "contribution statement": "This paper provides novel, context-specific evidence on the operational and financial mechanisms linking energy reliability to SME performance, filling a gap in qualitative literature from a region characterised by both energy poverty and economic informality
