Models for national energy policy analysis and planning

Two energy models have been developed that represent the national energy system. One of these is a 'fuel model' that includes only the major conversions and investments in the energy sector, covers a time span of 15 years and uses linear programming (LP) techniques. The other is an 'energy model' that includes the activities in the energy sector in considerable detail, covers a time span of 24 years, and uses mixed integer programming (MIP) formulation. The Fuel Model has been applied to Turkey for the years 1960-1975, while the 'Energy Model' has been used to analyze possible development for the years 1976-2000. Some of the results pertaining to the validation and analysis runs have been presented along with experiences in implementation of the models.
