Oahu Smart Grid Advanced Telemetry Mesh

Hawaiian Electric's grid-modernization programme had connected 118,841 solar systems across its island grids by September 2025 — enough that 49% of Oahu's single-family homes now have rooftop solar. Smart meters give the utility real-time visibility to balance that influx against a fully isolated grid that can't import power from anywhere else.
