Calliope is a framework to develop energy system models, with a focus on flexibility, high spatial and temporal resolution, the ability to execute many runs based on the same base model, and a clear separation of framework (code) and model (data). Its primary focus is on planning energy systems at scales ranging from urban districts to entire continents. In an optional operational it can also test a pre-defined system under different operational conditions.

A Calliope model consists of a collection of text files (in YAML and CSV formats) that fully define a model, with details on technologies, locations, resource potentials, etc. Calliope takes these files, constructs an optimization problem, solves it, and reports back results. Results can be saved to CSV or NetCDF files for further processing, or analysed directly in Python through Python's extensive scientific data processing capabilities provided by libraries like Pandas and xarray.

Calliope comes with several built-in analysis and visualisation tools. Having some knowledge of the Python programming language helps when running Calliope and using these tools, but is not a prerequisite.

Calliope can run on Windows, macOS and Linux. Installing it is quickest with the mamba package manager by running a single command: mamba create -c conda-forge -n calliope calliope.

See the documentation for more information on installing.

Several easy to understand example models are included with Calliope and accessible through the calliope.examples submodule.

The tutorials in the documentation run through these examples. A good place to start is to look at these tutorials to get a feel for how Calliope works, and then to read the "Introduction", "Building a model", "Running a model", and "Analysing a model" sections in the online documentation.

More fully-featured examples that have been used in peer-reviewed scientific publications are available in our model gallery.

Documentation is available on Read the Docs.

See our documentation for more on how to contribute to Calliope.
