Geomagnetically induced currents (GICs) are electrical currents that are generated in power grids due to variations in the Earth's magnetic field caused by solar activity, such as solar flares or coronal mass ejections from the sun. When these solar events interact with the Earth's magnetosphere, they can induce fluctuations in the geomagnetic field, which, in turn, create electric currents in conductive structures, including power lines and transformers. These GICs can flow into power systems, leading to potential issues such as transformer heating, voltage instability, and even outages. Utilities need to monitor geomagnetic activity and implement protective measures to mitigate the risks posed by GICs, ensuring the stability and reliability of the power grid during periods of heightened solar activity. Understanding and preparing for these currents is essential to maintain the ultimate resilience of the power infrastructure against the dynamic influences of space weather.
