dsgrid: Demand-Side Grid Model

NREL's demand-side grid (dsgrid) model harnesses decades of sector-specific energy modeling expertise to understand current and future U.S. electricity load for power systems analyses.

The primary purpose of dsgrid is to create comprehensive electricity load data sets at high temporal, geographic, sectoral, and end-use resolution. These data sets enable detailed analyses of current patterns and future projections of end-use loads.

The dsgrid platform uses a bottom-up methodology that allows highly resolved analysis of "what if" scenarios of future electricity load. It leverages multiple detailed sectoral energy models to provide hourly time series of load by subsector, end use, and U.S. county. Each dsgrid data set typically covers a full year, which either represents a historical year or a future model-year scenario.

Although dsgrid currently emphasizes electricity load data, its component sector models for residential buildings, commercial buildings, and industry provide information on other fuel use, including natural gas. The data sets can be leveraged to support analysis of numerous demand-side technology-driven changes, such as energy efficiency, electrification, and operational flexibility (i.e., demand response). The electricity use data are time-synchronized with solar and wind data sets and are thus suitable for use in power systems analysis.

Featured Projects

Electrification Futures Study

For NREL's Electrification Futures Study, the dsgrid team developed a high-resolution data set describing contiguous United States electrical load in 2012. The modeling methods and results are described in the dsgrid model documentation. This effort demonstrated the feasibility of high-resolution, bottom-up load modeling for large geographic extents using component models that can capture the impact of large technological change. By modeling a historical year and accounting for distributed generation and system losses (in the distribution and transmission systems), the team was able to quantify model residuals at multiple combinations of geographic, temporal, and sectoral resolution, and thus identify key areas for future improvements.

Los Angeles 100% Renewable Energy Study

NREL is developing a city-scale version of the dsgrid model for the Los Angeles 100% Renewable Energy Study. In this study, NREL is conducting a series of integrated modeling activities for the Los Angeles Department of Water and Power to understand the options and tradeoffs among different approaches to realizing the Los Angeles City Council's goal of meeting 100% of electricity demand with renewable resources.
