About the Distributed Generation Market Demand Model

NREL developed the Distributed Generation Market Demand (dGen) model to analyze the key factors that will affect future market demand for distributed solar, wind, storage, and other distributed energy resource (DER) technologies in the United States within a single modeling platform.

The dGen model is one of the premier national customer adoption models available, and it distinguishes itself from other models in two ways:

  1. All data are embedded in a spatially resolved database, which permits analysis at multiple geographic levels (national, state, and utility, or below).
  2. Customer adoption is modeled through an agent-based approach that permits sophistication in representation of decision-making regarding economic and behavioral considerations.

Learn about actual applications of the dGen model.

Examples of Analysis
