This is the raw data supporting the Total ELectricity Loads (TELL) model developed by the Integrated Multisector Multiscale Modeling (IM3) project led by Pacific Northwest National Laboratory. Information about the model itself and code to extract and work with this raw data can be found at: https://github.com/IMMM-SFA/tell. There are five core datasets in this package: 1) EIA_930 contains data on hourly electricity demand for 68 balancing authorities in the U.S. 2) EIA_861 contains an annual summary of the characteristics of the power industry in the U.S. 3) Population contains annual estimates of county- and state-level population in the U.S. 4) County_Shapefiles contains a set of shapefiles that define county boundaries for counties in the U.S. 4) State_Shapefiles contains a set of shapefiles that define state boundaries for states in the U.S.
