EnergyModelsInvestments

This Julia package provides the mathematical description of different investment options for energy system models. Initially, it was an extension package to the operational, multi carrier energy model EnergyModelsBase with an additional extension for geographical investments if EnergyModelsGeography was used.

However, since Version 0.7, EnergyModelsInvestments can be used independently from EnergyModelsBase to provide different investment options to existing energy system models written in JuMP. In this case, EnergyModelsInvestments provides a mathematical formulation for both different investement modes (e.g., discrete investments or semi-continuous investments) and lifetime modes (e.g., for the whole study period or only for a limitid number of years). A detailed description on how you can use EnergyModelsInvestments can be found in Use EnergyModelsInvestments.

EnergyModelsInvestments is designed to be an extensible package that can work with multiple different energy system model. In addition, it is designed for maximum flexibility and the potential to introduce new investment and lifetime modes without modifications to the core structure.
