The DES-model and its applications

This report describes the use of the Danish Energy System (DES) Model, which has been used for several years as the most comprehensive model for the energy planning. The structure of the Danish energy system is described, and a number of energy system parameters are explained, in particular the efficiencies and marginal costs of combined heat and power (CHP). Some associated models are briefly outlined, and the use of the model is described by examples concerning scenarios for the primary energy requirements and energy system costs up to the year 2000, planned development of the power and heating systems, assessment of nuclear power, and effects of changes in the energy supply system on the emissions of SO2 and NOsub(x).
