The last nautical mile

Emerging energy transitions for Pacific Islands.

Overview

This UNSW–UNDP project examined how to provide reliable, affordable, and sustainable electricity to remote Pacific Island communities, where isolation, dispersed populations, weak infrastructure, and reliance on imported fuels still limit access. It introduces the idea of the “last nautical mile” to capture the unique logistical challenges of ocean-separated settlements and argues for a whole-of-island planning approach that integrates energy with local economies and community needs, rather than fragmented projects. Across six case studies, solar home systems were common but faced maintenance, financing, and productive-use barriers, highlighting the need for energy justice (equity, inclusion, and recognition of local knowledge), gender-aware governance, and context-specific technologies (mainly solar PV, with micro-hydro, wind, or biomass where suitable). The report ultimately calls for coordinated planning tools, better repair and end-of-life management, creative financing models, regional cooperation, and locally grounded solutions to build resilient energy systems and support long-term development across Pacific islands.
