ETEM is a multi-sector, multi-energy, technology rich model specifically designed to analyse energy transition at regional and national level. A simplified representation of its reference energy system (RES) is shown in Figure 1. ETEM is a linear programming model related to the family of MARKAL/TIMES models developed under the aegis of the IEA/ETSAP. In ETEM, it is possible to represent demand and distribution constraints and options in a smart energy system. It is also possible to represent in ETEM power flow constraints and nodal marginal prices.
