Energy Transition Scenarios for Sardinia Island: Exploring Alternative Options for Decarbonization

This work presents a power system model of Sardinia Island in Italy, developed with the Calliope energy system optimization framework. It relies on a NUTS-3 geospatial resolution and analyzes multiple decarbonization scenarios for the Island with 2050 as target year. Using a scenario-based approach, the impact of key technologies central to the social and political debate - including the Tyrrhenian Link interconnection, photovoltaic and wind (onshore and offshore) farm and eventually synthetic fuels for the retrofit of fossil-fired plants - is assessed. Results highlight the critical role of both interconnections and strategic deployment of production technologies, showing that a fully decarbonized system can be achieved at an Equivalent Annual Cost of approximately 437 MEur.
