Invention Reference Number
Oak Ridge National Laboratory has developed the Grid Carbon Intensity Estimator (G-CIE), a geospatial analysis tool that enables stakeholders to estimate the carbon emissions associated with increased electricity demand—such as from vehicle charging—at the county level. This tool supports low-emission infrastructure planning as part of broader electrification strategies.
Description
G-CIE is a targeted subcomponent of ORNL’s OR-AGENT platform that estimates the carbon intensity (in grams of CO2 per kilowatt-hour) of additional electric loads placed on the U.S. power grid. Using historical power generation data, emission factors by fuel type, and region-specific grid behavior, G-CIE calculates localized emissions based on when and where the electric demand occurs. It correlates added load with electricity generation profiles from various Balancing Authorities and maps these emissions to U.S. counties using geographic information systems. By providing spatially and temporally resolved estimates of grid carbon impact, G-CIE allows planners to evaluate the environmental trade-offs of electrification scenarios. This enables smarter deployment of electric infrastructure in alignment with sustainability and regulatory goals.
