The Distributed Generation Market Demand (dGen) model simulates the potential adoption of distributed energy resources (DERs) for residential, commercial, and industrial entities in the continental United States through 2050. It's a geospatially rich, bottom-up, market-penetration model.

The dGen model can help develop deployment forecasts for distributed resources, including sensitivity to market and policy changes such as retail electricity rate structures, net energy metering, and technology costs. It can be employed at a wide range of spatial-temporal scales.

To analyze DER impacts on the bulk power system, it can be linked with NREL's Regional Energy Deployment System (ReEDS) model. For more information, read a related journal article.

Alternatively, the dGen model can be applied at a fine spatial resolution to predict adoption potential at the distribution feeder level.
