16/ Conclusions 2: Batteries support PV-battery hybrids & grid interconnection enhances flexibility, reduces costs & supports wind with limited PV. Sector coupling & PtX improve efficiency. Electric road transport with V2G adds flexibility & grid-connected renew paths are 1-10% cheaper.

13/ #Cuba generates 25% of the #Caribbean’s 863 TWh electricity, followed by #Haiti and the Dominican Republic at 17% each. The regional average price is 30 €/MWh, with four nodes below this. By 2050, e-hydrogen and e-FTL fuels will comprise 46% and 30% of the fuel supply, respectively.

11/ Renewables-dominated paths have 7-24% lower cumulative costs as alternatives, with grid integration cutting costs by 1-10%. Accelerated transition paths cost 3-12% more as full defossilisation by 2050. Importing e-fuels lowers system costs by 7-16% & supports local resource use.

9/ Three electricity trade patterns are observed: With 1% onshore PV, CU and DO lead exports (90 TWh, 45 TWh), and HT is the top importer (80 TWh). Higher wind shares shift exports to CU (85 TWh), TCBB (70 TWh), PRV (35 TWh), and HT imports 110 TWh. The third pattern is with 6% onshore PV.

8/ Grid utilisation correlates with dominant technology profiles, such as solar PV or wind power. Scenarios with 30% wind show higher grid utilisation, indicating a wind-grid correlation, while those with 12% wind power have lower utilisation, showing a PV-storage correlation.
