Why Calliope?
Tried and tested in peer-reviewed publications
The Calliope code is tested with a comprehensive suite of automated software tests and has been used in a large range of peer-reviewed publications (see the list of publications).
Accelerate work by re-using existing models
For example, the fully open-source Sector-Coupled Euro-Calliope: a model of the entire European energy system built with Calliope.
Easy-to-use building blocks
Building a model is easy using Calliope's flexible text-based model definition format. The example shows the definition of a basic CCGT power plant. See example model tutorial.ccgt:
essentials:
name: 'Combined Cycle Gas Power Plant'
color: '#FDC97D'
parent: 'supply'
carrier_out: 'electricity'
constraints:
resource: inf
energy_cap_max: 40000 # kW
energy_ramping: 0.8
costs:
monetary:
energy_cap: 750 # USD per kW
om_con: 0.02 # USD per kWh
Interactive visualisations built-in
Calliope provides interactive visualisation of results from a model. Try it with the example shown, which includes three energy carriers: electricity, heat, and gas. Use the dropdown to switch between different views. See more visualisation capabilities.Build on top of a free and open codebase
Calliope is completely freely and openly available under an Apache 2.0 license. By extensively using automated tests, it provides a solid foundation on which to build transparent and reproducible energy system models. Development happens in the open on GitHub.
