Long-Term and Short-Term Analysis of the Transition Toward a Full Renewable Energy Supply in Galapagos Islands by 2050

Galapagos Islands are one of the most important World Heritage Sites and a truly unique place for studying and understanding the Nature and evolution. The islands have an energy supply system predominantly based on fossil fuels (currently around 83.6%), which is polluting the air, the land and the sea, endangering fragile ecosystems that Nature has preserved for so long. This paper presents the analysis of the optimal decarbonization of energy supply in Galapagos Islands, which compares the results of a long-term planning study and a short-term operational analysis. It details the development of models and simulation tools for the evaluation of existing and future energy supply systems, based on the projections and targets for full renewable energy supply by 2050. The considered renewable technologies include PV and wind generation, together with dedicated battery energy storage system.
