Energy policy evaluation modelers traditionally have been divided between two disjoint modeling approaches due to data and other incompatibilities: bottom-up and top-down models. Some efforts have been attempted to incorporate technological richness in top-down models, especially by the introduction of supply-side electricity generation detail into accountability frameworks, however electricity demand disaggregation has been completely neglected in general equilibrium models. This paper develops a solution to represent both supply technological richness and demand time heterogeneous electricity behavior in a way that is consistent with a social accounting framework. Goal programming approach was utilized in order to achieve the numerical calibration of the significant amount of economic and engineering data required. Moreover, physical constraints as thermal efficiency transformation of fuels were dealt in order to avoid inconsistencies on the economical representation and time based disaggregation presented. The process is illustrated with data from Spanish electricity sector.
