Future-Ready Power Systems: Building Resilient and Circular Energy Pathways for Pacific Islands

Pacific Island utilities stand at a pivotal moment as climate change accelerates the frequency of Category 5 cyclones, sea-level rise, and extreme heat—threats that increasingly exceed the design tolerances of existing grid infrastructure. The session's first discussion, Resilience & Renewables: Powering the Pacific's Green Frontier, explores how utilities can harden assets against 300 km/h winds, mitigate corrosion from rising salt spray, and plan for the growing likelihood that coastal power infrastructure may require relocation rather than reinforcement. The panel dives into the practical realities utilities face: stabilizing grids with high penetrations of solar, addressing battery degradation in tropical heat, and preparing for the operational challenges of achieving 100% renewable energy targets. It also examines the policy and financing gaps that currently limit utilities from moving beyond one-off donor-funded projects toward regionally scalable, bankable solutions capable of delivering long-term resilience.

The second discussion, Closing the Loop – End-of-Life Management and Infrastructure Circularity, shifts the lens to an equally urgent but often overlooked dimension of the energy transition: the rapidly expanding wave of end-of-life solar panels, batteries, and related infrastructure that Pacific states will soon be required to manage. As islands accelerate renewable energy deployment, they are effectively importing future waste streams without the land area, recycling facilities, or regulatory frameworks to manage them. This panel will explore practical pathways for integrating circularity from the design stage—such as embedding decommissioning requirements in tenders, adopting extended producer responsibility, and developing second-life uses for degraded batteries. It will also examine the viability of regional "hub-and-spoke" waste aggregation models, the role of SPREP and PPA in regional coordination, and financing mechanisms such as advanced disposal fees or product stewardship funds to offset high shipping costs. Together, the two panels provide a comprehensive look at building Pacific energy systems that are not only resilient in operation but sustainable across the full lifecycle of infrastructure.
