The Caribbean region continues to beplagued by high and volatile fuel prices, with limitedeconomies of scale or diversity in electricity supply.Although several studies have examined alternative resourceoptions for the region, they often only consider solutionsfor individual countries in isolation. When one looks at theCaribbean, however, it is apparent that the short distancesbetween islands and market sizes present opportunities tobenefit from regional solutions. Indeed, increasinginterconnection in the Caribbean could pave the way forgreater energy security, a larger use of renewable andenhanced climate resilience. The idea of regionalinterconnections is not new: gas pipelines are widely usedto interconnect gas supply with gas demand, and electricitymarket interconnections have become the norm around theworld. However, this option does not appear to have receivedthe attention it merits in the specific context of theCaribbean. While this study analyzes a small subset of theimaginable regional energy options for the Caribbean, itshows that regional solutions warrant further study. Thissynthesis report builds from the technical report that theWorld Bank commissioned from Nexant, entitled-Caribbeanregional electricity generation, interconnection, and fuelssupply strategy. It analyzes a range of regional options.Although further analysis is required, the hope is that thissynthesis report will help to fuel the conversation aboutinterconnected development pathways for the Caribbean.
