ELTRAMOD-stud – A study model that entails a model-endogenous power capacity expansion and power plant dispatch developed to be deployed in energy economics courses Employing the assumptions of perfect competition and contestable markets, the cost-optimal generation capacity portfolio determined by ELTRAMOD-stud mimics the long-term market equilibrium under the assumption of immediate capacity adaptation. Capacity expansion models such as ELTRAMOD-stud are typically utilised to investigate long-term energy scenarios. The model can also be easily adjusted to derive short-term market equilibria, whereby the capacity variables are exogenously fixed. Depending on the specific course level and modelling skills of students, the model can easily be extended to study further aspects of electricity systems, e.g., questions related to flexibility options and sector-coupling technologies or the implications of environmental policies.
