The commercial and industrial ESS market in the Caribbean is entering a phase of rapid emergence and strategic opportunity. High electricity costs, unstable grids, and frequent hurricanes have driven rising demand for distributed energy storage. In countries such as Puerto Rico, Jamaica, the Dominican Republic, and Panama, industries such as tourism, manufacturing, and retail are in urgent need of power stability and green energy solutions. ATESS recognizes the long-term potential of this emerging region and, through Bluesun’s local expertise in distribution, service, and support, will accelerate the deployment of solar-plus-storage systems for small to medium-scale commercial users.
