Therefore, the structure model consists of 4 main modules, namely: (i) key assumptions, (ii) demand, (iii) transformation and (iv ) resources. The key assumptions module is used to define the general variable used in the model like number of population and its growth, amount of GDP and its growth, energy price, exchange rates, economic structure, etc. The demand and transformation module is designed to take into account available data regarding variable energy demand and supply. The energy demand variable is usually the activity level and energy intensity, while the energy transformation variable is much more complicated depending on various technologies. Each sub-module generally includes technical variables such as planned reserve margin, system peak load shape, efficiency factor (conversion), capacity factor, dispatch mode, properties mode production, the energy contract engaged (export and import), etc. The resource module is used to enter energy resources
