| Primary Purpose | Euro-Calliope is a suite of pre-built models and routines to build these models from raw data. You can configure, adapt, and extend both models and routines in many ways to build your own model that is fit for your purpose. Calliope is an energy systems linear optimisation framework, 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). Energy system planning/operation problems can be easily built, optimised for minimum cost (or other metrics, such as environmental impact) and analysed. It is highly usable for non-technical researchers, whilst maintaining a clear code-base for extendability by interested software developers. |
| Primary Outputs | The model outputs are the technology investment portfolio for a given system, be it a network describing an entire country, or just a district of a few buildings, and the operation schedule for those technologies to meet demand. The operation schedule can be as high resolution as the data available to the user, with hourly timesteps being standard for our research. |
