Cayman Islands Electricity Access

The Cayman Islands has achieved universal electricity access, with the World Bank reporting a coverage rate of 100.00 % in 2025, the highest level recorded since the series began in 1990 when the rate stood at 99.85 %. This modest rise to full coverage marks the all‑time peak for the territory and places it joint‑first with peers such as Curaçao, Cyprus, China and Czechia, each also reporting 100.00 % access. The 35‑year span of data shows a steady, almost complete saturation of the grid, reflecting the islands’ small population, high per‑capita income and substantial investment in modern energy infrastructure. While the current level leaves little room for further quantitative improvement, future changes could arise from the integration of renewable generation, grid resilience upgrades or policy shifts toward decentralised micro‑grids, which may reshape the composition rather than the extent of electricity access.
