From Silos to Synergy: How supply chain integration drives organizational performance in Nigeria's renewable energy sector

Abstract

Purpose: Nigeria's renewable energy sector is expanding rapidly, yet fragmented supply chains continue to constrain the operational and service-delivery performance of firms within it. This study examines the effect of four dimensions of supply chain integration (SCI); internal, supplier, customer, and strategic; on the organisational performance of renewable energy firms in Lagos State, Nigeria. Design/methodology/approach: A quantitative, positivist, cross-sectional design was adopted. Structured questionnaires were administered to 100 employees and managers drawn from two renewable energy organisations operating four branches across Lagos State. Data were analysed using descriptive statistics, Pearson correlation, and simple linear regression in SPSS 23, informed by a resource-based view (RBV) and contingency-theory framework. Findings: All four hypotheses were supported. Internal integration explained the largest share of variance in organisational performance (R² = .816), followed by overall/strategic integration (R² = .733), supplier integration (R² = .662), and customer integration (R² ≈ .663). Real-time data sharing, open supplier communication, and cross-departmental alignment were the most strongly endorsed integration practices (mean ratings above 4.0 on a 5-point scale). Originality/value: While SCI–performance relationships are well documented in manufacturing, banking, and general service contexts, empirical evidence from Nigeria's renewable energy sector remains scarce. This paper extends SCI theory into an emerging-market energy context shaped by infrastructural and regulatory constraints, and offers practical guidance for managers and policymakers seeking to strengthen integration practices.
