The standard U.S. Regional Economy, Greenhouse Gas, and Energy (US-REGEN) electric sector model incorporates a relatively stylized representation of dispatch that excludes several operational constraints and unit-level detail. In recognition of these limitations, a stand-alone unit commitment version of US-REGEN has been developed to better understand the short-run costs and engineering challenges of operating the capacity mixes suggested by the full US-REGEN dynamic model. This unit commitment model investigates power system operations on an hourly level for each unit over an annual time horizon and includes constraints related to ramping, turndown limits, and startups, which are not traditionally captured in reduced-form representations of dispatch. Given the significance of transmission and trade as flexibility resources in electricity markets, a novel feature of the model is its endogenous treatment of imports and exports across regions. This report describes the unit commitment model, its capabilities, and its relation to the dynamic version of US-REGEN.
