The document introduces a novel five-step modelling framework designed to identify power infrastructure vulnerabilities and design cost-optimal decentralized renewable energy (DRE) solutions for islands and low-lying states. The framework involves identifying disruption hotspots, assessing disruptive potential, designing DRE systems using HOMER Pro, integrating local contextual factors, and evaluating resilience improvements. Testing the framework in Cuba revealed that municipalities with high electricity demand from industries and large buildings are most vulnerable to single-point failures. The results demonstrate that while DRE systems—incorporating solar PV, wind, battery storage, and biomass—improve power supply continuity, their effectiveness and cost are heavily influenced by local contexts, such as the US embargo on Cuba, which increased capital investment costs by 5-40% compared to global scenarios.
