Abstract
GENeSYS-MOD is a flexible framework that allows the modeling of energy systems at various
degrees of detail, with a focus on sector coupling and the computation of long-term pathways
for the energy system. The generic formulation makes the framework suitable for a wide range
of use cases, allowing for a widely user-defined resolution in terms of temporal, spatial, and
technological detail. GENeSYS-MOD performs a cost-optimizing investment and dispatch
calculation across all modeled subsectors of the energy system (usually covering at least
electricity, buildings, industry, and transport). The newest, fourth version of the framework is
now available in both GAMS and Julia for the core model, with optional data management
tools written in Python.
