"abstract": "A once-per-century geoelectric hazard map is created for the United States high-voltage\n\tpower grid. A statistical extrapolation from 31 years of magnetic field measurements is\n\tmade by identifying 84 geomagnetic storms with the Kp and Dst indices. Data from 24\n\tgeomagnetic observatories, 1079 magnetotelluric survey sites, and 17,258 transmission\n\tlines are utilized to perform a geoelectric hazard analysis with the most comprehensive\n\tdata publicly available. With this data we estimate once-per-century geoelectric fields at\n\tthe magnetotelluric survey sites and calculate the theoretical voltages within transmission\n\tlines in the United States power grid. Once-per-century geoelectric field strengths span\n\tmore than three orders of magnitude from a minimum of 0.02 V/km at a site in Idaho to a\n\tmaximum of 26.8 V/km at a site in Maine, with nearly 30% of the surveyed land area ex-\n\tceeding 1 V/km. We show the influence that geoelectric field polarization has on geoelec-\n\ttric hazards when viewed on a power transmission network. The calculated transmission\n\tline voltages can exceed 1000 V in some transmission lines. Four regions in the United\n\tStates with particularly notable geoelectric hazards are identified and discussed: the East\n\tcoast, Pacific Northwest, upper Midwest, and the Denver metropolitan area.",
