The Regional Energy Deployment System (ReEDS) (formerly known as the Wind Deployment System or WinDS) model is a computer model that optimizes the regional expansion of electric generation and transmission capacity in the continental United States over the next 50 years. This ReEDS Web site presents an overview of this NREL-developed tool, as well as relevant data and related publications. Site users also will find background on the model as well as a detailed model description. ReEDS is unique among capacity expansion models for its highly discretized regional structure and stochastic treatment of the impact of variability of wind and solar resources on capacity planning and dispatch. Along with numerous independent analyses, ReEDS was used prominently for the 20% Wind Energy by 2030 report and is currently being applied to the Renewable Energy Futures Study—an analysis of how the United States might provide 80% of its electricity from renewable sources.
