The Distributed Generation Market Demand (dGen) model is a geospatially rich, bottom-up, market-penetration model that simulates the potential adoption of distributed energy resources (DERs) for residential, commercial, and industrial entities in the continental United States through 2050. The dGen model builds on and provides significant advances over NREL's deprecated Solar Deployment System (SolarDS) 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. The model can be employed at a wide range of spatial-temporal scales, it can a be linked with NREL's Regional Energy Deployment System (ReEDS) model to analyze DER impacts on the bulk power system. Alternatively, dGen can be applied at a fine spatial resolution to predict adoption potential at the distribution feeder level.
