title: U.S. TIMES EPAUS9rT Data 16.1.3

description: United States Environmental Protection Agency<br> https://www.epa.gov/air-research/epaus9rt-energy-systems-database-use-times-model The EPAUS9rT is a 9-region database representation of the U.S. energy system. The regional breakdown is based on the nine U.S. census divisions. The database was developed by EPA researchers for use with the TIMES model. TIMES is an energy system optimization model used by local and federal governments, national and international communities and academia. It helps decision makers understand the complex system interactions related to energy use. The Energy Technology Systems Analysis Programme (ETSAP) of the International Energy Agency oversees its development. The EPAUS9rT is a fully transparent, publicly available database. The unique contribution of this database lies in its thorough representation of greenhouse gas (GHG) and air pollutant emissions. EPA researchers use the TIMES modeling platform to analyze the environmental impacts of potential changes in the way the U.S. produces and uses energy. The EPAUS9rT represents energy supply, technology, and demand throughout the major sectors of the U.S. energy system. The sectors include: commercial, industrial, residential, transportation, and electricity generation. Energy resources represented in the database include: coal, natural gas, nuclear, petroleum, and renewable (e.g., wind, solar, biomass, geothermal, and hydropower). The EPAUS9rT has a set of baseline assumptions developed characterizing U.S. energy supplies, demands, and technologies through the year 2050 in multi-year increments at the level of the nine U.S. Census Divisions. How does the database work? TIMES is a least cost optimization model. When run with EPAUS9rT, it calculates the least cost set of technologies that satisfy the specified demands over time, subject to user-defined constraints. Outputs of the model include: The technological mix at intervals into the future Total system cost and energy demand (by type and quantity) GHG and air pollutant emissions What are the benefits of using this energy systems database? The EPAUS9rT can be used with the TIMES modeling platform to evaluate the effects of alternative future technology scenarios on air pollutant and GHG emission levels. Users can identify cost-effective and environmentally friendly energy strategies for electric power generation, and for meeting the energy demands of industrial processes, the transportation system, and buildings. Users can customize their future energy scenarios to include reduction targets for carbon dioxide emissions; water availability for electricity generation; and advances in technology. The analyses of these scenarios can provide decision makers with a better understanding of how a changing energy landscape will affect future air quality and contribute to meeting mitigation targets and adaptation goals. Who should use the databases? Universities, non-government organizations, and other governmental agencies use the EPAUS9r in their research. It is also used extensively by EPA for a variety of analyses.
