Balmorel is a model representing an international energy system with emphasis on the electricity and combined heat and power sectors. It is developed and maintained in the Balmorel project, which aims at supporting modeling and analysis of the energy sector, including aspects of energy, environment and economy. The Balmorel model has been used by energy system experts, energy companies, authorities, transmission system operators, researchers and others for the analysis of future developments of a regional energy sector. The model is developed and distributed under open source ideals, meaning that the GAMS code for the model, with documentation, data and application examples are available for download, application and modification. The Balmorel project supports experience exchange and co-operation on application of the model.
