Abstract
The project 'Integrated models for analysis of Regulatory impacts and Simulations of long-term scenarios of energy sector development' (RegSim) used several integrated impact assessment models (partial-equilibrium energy market model TIMES, macro-econometric model E3ME, and hybrid CGE model) to analyse the impacts of decarbonisation policies and to stimulate long-term energy scenarios. The project provides the public administration, mainly to the Ministry of the Environment and the Ministry of Industry and Trade of the Czech Republic, with a scientifically-based quantification of the impacts of regulations and background material for the generation of medium- and long-term scenarios and trends in the energy sector, strategic planning, and policy formulation with the horizon of 2050.
