Geomagnetically induced currents are known to induce disturbances in the electric power grid. Here we perform a statistical analysis of 11,242 insurance claims from 2000 through 2010 for equipment losses and related business interruptions in North American commercial organizations that are associated with damage to, or malfunction of, electrical and electronic equipment. We find that claim rates are elevated on days with elevated geomagnetic activity by approximately 20% for the top 5% and by… 

Statistical Analysis of the Correlation Between Anomalies in the Czech Electric Power Grid and Geomagnetic Activity

Eruptive events on the Sun have an impact on the immediate surroundings of the Earth. Through induction of electric currents, they also affect Earth‐bound structures such as the electric power

Immediate and delayed responses of power lines and transformers in the Czech electric power grid to geomagnetic storms

Eruptive events of solar activity often trigger abrupt variations of the geomagnetic field. Through the induction of electric currents, human infrastructures are also affected, namely the equipment

Why Space Weather Is Relevant to Electrical Power Systems

Twenty-five years of research has produced a wide range of models of the causal processes linking solar wind to geomagnetic disturbances to geomagnetically induced currents (GICs) and grid
