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

US Regen Infographic

The US Regional Economy, Greenhouse Gas, and Energy Model (US-REGEN) is a model developed by the Electric Power Research Institute. It combines: (1) a detailed dispatch and capacity expansion model of the United States electric sector which includes representation of both existing generation unit capacity and the hourly profiles of load, wind speed and solar flux, (2) an end-use model which represents trade-offs between end-use technologies and fuels for a wide range of disaggregated sectors and activities with economy-wide coverage and includes structural detail across several dimensions relevant for fuel and technology choice, such as building size, type, and vintage, climate zone and location, and vehicle ownership and driving intensity, (3) a fuels model describing the supply and conversion of primary energy into delivered fuels supplied to the electric and end-use models which includes several technologies for conversion, blending, and synthesis of fuels, including petroleum refining, biomass to liquids or gas, blending fuel supply, ammonia production, and fuel synthesis.

The three models are solved iteratively to convergence, allowing analysis of policy impacts on the electric sector taking into account economy level responses. This makes REGEN capable of demonstrating the least-cost deployment mix of generation subject to a scenario-dependent range of technological and policy constraints or other drivers of future fuel supply and energy demand.

Canada Regional Economy, Greenhouse Gas, and Energy (Canada REGEN)

US Regen Infographic

The Canada Regional Economy, Greenhouse Gas, and Energy Model (Canada REGEN) is a 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 considering economy level responses.

Model for Estimating the Regional and Global Effects of Greenhouse Gas Reductions (MERGE)

MERGE is an intertemporal general equilibrium model with a reduced-form representation of the economy, the energy sector, related emissions and concentrations of carbon dioxide and other greenhouse gases, and the climate system. It is designed to be sufficiently transparent to allow exploration of the implications of alternative viewpoints in the greenhouse debate.

Forestry and Agricultural Sector Optimization Model with Greenhouse Gases (FASOM-GHG) Description / Results List

The Forestry and Agricultural Sector Optimization Model with Greenhouse Gases (FASOM-GHG) is an intertemporal partial equilibrium model of the U.S. forestry and agricultural economic sectors, including biomass production for bioenergy. It is designed for detailed evaluation of potential changes in future U.S. forestry and agriculture commodity production and consumption, land management, land allocation, and greenhouse gases with respect to alternative economic, technological, biophysical, and policy scenarios.

Electric Generation Expansion Analysis System

The Electric Generation Expansion Analysis System (EGEAS) is a modular state-of-the-art generation expansion software package. EGEAS is used by utility planners to produce integrated resource plans, evaluate independent power producers, develop avoided costs and environmental compliance plans, and analyze life extension alternatives. EGEAS is a set of computer modules that determine an optimum expansion plan or simulate detailed production costs for a prespecified plan. Expansion plans are defined by the type, size, and installation date for each new generating facility or demand-side management resource. Optimum expansion plans are developed in terms of annual costs, operating expenses, and carrying charges on investment. The objective is to find an integrated resource plan that meets the objective function specified by the user. The two objective functions in EGEAS include: minimizing total present worth costs and minimizing levelized annual customer rates.
