This study evaluates the current energysituation in the member states of the Organization ofEastern Caribbean States (OECS) and identifies selectedinvestment options and policy issues for new energyprojects. The emphasis of the study is on large energysystems and ways to link one of more of the OECS countries.Complementary smaller-scale systems, in the form of wind,are also considered. This study is not an exhaustive surveyeither of each OECS member country or of all possible energytechnologies for the OECS countries. Rather, it is intendedto address the key energy-economy interaction in theelectricity sector and to assess potential new supplyinvestments. A key issue is how to bring some of thebenefits of larger scale, more efficient power generationtechnology to these small island systems. The report beginswith a summary of recommendations and findings for OECSpolicies and actions. Part 1 contains an assessment of theenergy sector with two main components, a review of recentstudies on energy in the OECS, and a summary of current useof fuel and energy, primarily electricity in the OECS memberstates. Part 2 starts with a review of internationalexperiences in island energy systems, including integrationefforts. Based on the review of previous work, ongoingefforts in the region and the energy needs of the OECSmembers, several options are discussed in Chapter 5 for bothlarge and small-scale investments. These include (1)inter-island gas pipeline; (2) Liquefied naturalgas/compressed natural gas supply; (3) geothermaldevelopment with cable links to other islands; and (4) windfarms, linked to multi-island power systems. Chapter 6highlights the costs associated with various options, andChapter 7 shows the economic and financial aspects of thevarious options, as well as their compatibility with policyobjectives extracted from OECS member country energystrategy documents.
