Decarbonising the power sector of the Dominican Republic: An approach from electric mobility transition

The electrical power and land transportation systems of the Dominican Republic are facing significant challenges due to growing demand in both sectors. These two systems are responsible for around 62% of greenhouse gas (GHG) emissions. With the deployment of electric mobility, the power and transport sectors can synergise and contribute significantly to long-term sustainable planning. This article analyses the impact of the penetration of electric mobility programmed by the Dominican Republic's National Institute of Transit and Land Transport (INTRANT), the country's goal of reducing GHG emissions by 27% by 2030 and the decarbonisation process. Using the open-source modelling system OSeMOSYS, four scenarios are built to explore strategies that contribute to sustainable development in the long term. Meeting climate change commitments necessitates that all coal-fired plants in the country will be closed or transformed by 2040. Despite the positive role of electric mobility in reducing GHG, decarbonising the electricity sector while facing the energy crisis requires investments totalling around 16 billion USD. Failing to make these investments will incur expenses of approximately 6 billion USD on the user's side in the period from 2024 to 2030 to cover energy needs; this figure represents more than 270% of the amount that should be invested in the electrical power system to supply these users' needs.
