The Regional Energy Deployment System (ReEDS) is NREL's flagship capacity planning model for the power sector.

The model simulates the evolution of the bulk power system—generation and transmission—from present day through 2050 or later.

Learn more about the ReEDS model or watch a video training series. Each tutorial focuses on a different aspect of the model and includes a demonstration by a ReEDS developer.
