Role of the National Energy System Modelling in the Process of the Policy Development

Strategic planning and decision making, nonetheless making energy policies and strategies, is very extensive and has to follow multiple and often contradictory objectives. During the preparation of the new Slovenian National Energy Programme proposal complete update of the technology and sector oriented bottom up model REES-SLO (Reference Energy and Environmental System of Slovenia) has been done. Within the new model the comparison and assessment of various strategies on the demand and supply side with calculations of long term energy and emission balances and economic evaluation has been enabled. A linear network model of the national energy system for decision support was developed in MESAP (Modular Energy System Analysis and Planning) environment. MESAP open structure was used to build the model addressing the most relevant questions. During the model development, special attention was given to the aggregation of the data in accordance with statistical standards for data classification, also fully compatible with international reporting standards. Economic activities are disaggregated by branches, manufacturing industry and service sectors are further disaggregated on the subbranch level. Parallel competitive technologies have been included in the model. This was done where fuel switching is expected or where considerable energy efficiency improvements may differ significantly by strategies. Parallel modelling enabled accurate estimation of induced costs and environmental impacts. Within the paper the main technical, economic and environmental characteristics of the Slovenian energy system model REES-SLO are described. Also, the possibilities for the improvement of the model and its role in the policy follow-up process are discussed.
