US-REGEN – U.S. Regional Economy, Greenhouse Gas, and Energy US-REGEN

The US Regional Economy, Greenhouse Gas, and Energy Model (US-REGEN) is a new model developed by the Electric Power Research Institute. It combines a detailed dispatch and capacity expansion model of the United States electric sector with a high-level dynamic computable general equilibrium (CGE) model of the United States economy,

The US Regional Economy, Greenhouse Gas, and Energy Model (US-REGEN) is a new model developed by the Electric Power Research Institute. It combines a detailed dispatch and capacity expansion model of the United States electric sector with a high-level dynamic computable general equilibrium (CGE) model of the United States economy, including sectoral detail in electric power production, energy demand, and transportation. The two models are solved iteratively to convergence, allowing analysis of policy impacts on the electric sector taking into account economy level responses. This makes US-REGEN capable of modeling a wide range of environmental and energy policies in both the electric and non-electric sectors.
