Abstract:

Over the past two years, the IEA has worked to develop a new integrated modelling framework: the IEA’s Global Energy and Climate (GEC) Model. This model is now the principal tool used to generate detailed sector-by-sector and region-by-region long-term scenarios across IEA's publications. The GEC Model brings together the unique modelling capabilities of the WEM and ETP models. The result is a large-scale, bottom-up partial-optimisation modelling framework allowing for a unique set of analytical capacities in energy markets, technology trends, policy strategies and investments across the energy sector that would be critical to achieve climate goals. The IEA’s GEC Model covers 29 regions that can be aggregated to world-level results, and covers all sectors across the energy system with dedicated bottom-up modelling for: Final energy demand, Energy transformation, and Energy supply.
