OSeMOSYS is an open source modelling system for long-run integrated assessment and energy planning. It has been employed to develop energy systems models from the scale of the globe, continents, countries, regions and villages. It can focuses on detailed power representations, or multi-resource (material, financial, all energy) systems.
Over 60 national models and data kits are documented and available for free to get your research going! (Navigate to the 'Supplementary Files' section of these papers for the OSeMOSYS model and data file.)
It is available in three languages: (1) GNUMathprog, (2) Python and (3) GAMS. (1)-(2) can be run free and openly from source-to-solver.
All code basis are maintained in GitHub and contributions are welcome.
