Linking GCAM with specialized power system models to assess Norwegian energy and climate policy in a European context

To analyse the development of the European energy system and the impact on countries different types of models are integrated in the analysis. In a first step, the integrated assessment model, GCAM, provides contextual assumptions and the results are linked with a more detailed model of the European power system, EMPIRE. GCAM results such as annual electricity consumption and fuel prices are broken down to a national level and used in EMPIRE. EMPIRE computes optimal investments in generation, interconnectors and energy storage at national levels.
