Calliope is a free and open-source (Apache 2.0 licensed) tool that makes it easy to build energy system models at scales ranging from urban districts to entire continents.
- Calliope is used extensively in research and commercial applications.
- For a quick intro see “Why Calliope?” below and the quick start section on the support page.
- See the installation instructions to get Calliope running on your computer.
- Ask questions and discuss on our Gitter chat (see support page for more options).
- Development takes place in the open on GitHub.
Tried and tested in peer-reviewed publicationsThe 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 modelsFor example, the fully open-source Sector-Coupled Euro-Calliope: a model of the entire European energy system built with Calliope.
Easy-to-use building blocksBuilding 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.
