In the field of energy systems modeling, a model that simulates the entire Andorran energy sector has been developed, integrating socio-economic and environmental aspects of the country. The model implemented with the LEAP (Long range Energy Alternatives Planning system) allows the construction of medium and long term future scenarios based on observed historical trends, forecasts of national and international organizations, the introduction of new policies or a wide range of hypotheses (i.e., introduction of new technologies, increase in oil prices, variations in gross domestic product, etc.). In parallel, the model assesses the country's energy security in the resulting scenarios, which outline a wide range of possible futures, from now until 2050 [1].

The LEAP-Andorra model [2] characterizes in detail the two main modules that represent the pillars of any energy system: energy consumption and energy supply. At the same time, the energy consumption module is conformed by sub-models of the different sectors of the Andorran economy (residential, transport [3], secondary, tertiary and public administration). These have been modeled combining top-down and bottom-up techniques depending on the available data and the objectives set in the characterization of each sector. The aggregation of all sectors of the economy and the high level of detail of the LEAP-Andorra model allows the introduction of policy strategies and the quantification of their impacts at national level both in terms of energy and greenhouse gases (GHG).
