Potential clean energy transition pathways in the U.S. Virgin Islands using carbon sensitive policy options

Abstract

This study uses the LEAP–OSeMOSYS modeling tool to examine exploratory decarbonization scenarios in the U. S Virgin Islands (USVI). The method combines quantitative modeling of data gathered from utilities and power generators with qualitative information gathered through engagement with experts and diverse business and civil society stakeholder. The results show the effects of two utility scale energy systems - on the islands of St Thomas /St John and St Croix - and future optimized capacity addition with solar, liquefied petroleum gas and wind, whereby renewable energy targets can be achieved over time. Results are also modelled for electric vehicle deployment over time, on the islands. The models take into consideration the effects of extreme weather event impacts on electricity demand; and electric vehicles deployment on the grid, where grid destabilization is a potential risk. These findings can serve as inputs for updating comprehensive island energy strategies in the USVI to meet carbon emissions reduction goals.
