This document summarizes a proposal to develop a methodology for soft-linking TIMES energy system models with the GTAP computable general equilibrium model. The project would identify the data exchange between the models, develop case studies linking models for four countries, and create a user interface to facilitate the linking. The goals are to improve energy-economy modeling capabilities and provide a method for using consistent economic drivers across TIMES models based on GTAP projections. The proposal requests €86,900 over one year from ETSAP and partners to support linking methodology development and case studies.
