Overview

OPEN-PROM (“open PROMETHEUS”) is a modular, open-source, simulation-based integrated assessment model of the global energy system. It projects energy demand, energy supply, technology deployment, fuel use, prices, and emissions under alternative macroeconomic, technological, resource, and climate-policy assumptions.

Key characteristics:

  • Global, country-resolved — 39 countries and regions, with EU Member States and major economies modelled individually.

  • Recursive-dynamic — annual steps from 2024 to 2100, calibrated on historical data from 2010.

  • Technology-rich — explicit demand sectors (industry, domestic, transport, non-energy, bunkers) and supply sectors (electricity, heat, hydrogen, other fuels), with technology turnover handled by the gap-and-substitution mechanism.

  • An integrated toolchain — the model is fed by mrprom (input-data pipeline) and analysed with postprom (post-processing and reporting).

The documentation is organised as follows:

  • Getting started (this section) — this overview and the first steps for setting up and running the model.

  • How-to guides — task-oriented guides for input data, development, and model coupling.

  • Model documentation — the scientific reference: model structure, sectors, mechanisms, equations, the data pipeline, calibration, model interlinkages, and baseline results.

  • Reference — GAMS error codes, abbreviations, and bibliography.

  • Project — acknowledgements, funding, and how to cite OPEN-PROM.
