The U.S. Regional Economy, Greenhouse Gas, and Energy (US-REGEN) model links a detailed electric sector capacity planning and fuels supply model with representations of demand in buildings, transport, and industry. The open-source version of US-REGEN includes the electric sector model that jointly optimizes regional investments in electricity generation and energy storage, system dispatch, transmission, and non-electric fuels supply, which includes high temporal resolution and chronology to better characterize the economic incentives of variable renewables, energy storage, and dispatchable generation. Detailed US-REGEN model documentation and recent peer-reviewed articles and white papers can be found at https://esca.epri.com/models.html

Benefits & Values
- US-REGEN provides a customizable platform for policy analysis, technology assessment, and strategy that is informed by decades of EPRI research on energy modeling and technology analysis.
- The electric sector model represents detailed dispatch and capacity expansion and includes the representation of a range of electric sector resources that can be jointly optimized under a range of technology, policy, and market assumptions.
- The fuels model describes 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.
Platform Requirements
This version of US-REGEN has been tested in GAMS version 47.
