Geoelectric fields, induced in the electrically conducting Earth by storm-time geomagnetic field variation, can interfere with the transmission of electric power -- sometimes causing blackouts and damaging power-system infrastructure. Accurate estimation of such storm-induction hazards tests our scientific understanding, and is needed for vulnerability and risk assessments. For this session, we invite abstracts documenting recent progress in analyzing storm-induction hazards, including historical events, statistical and scenario analyses, physics-based and empirically-based modeling, retrospective and real-time modeling, direct measurement, prediction and forecasting, error analyses, model validation, system impacts, system vulnerability, and risk.
