Solar Storm Mitigation Fact Sheet

Space weather is a naturally occurring phenomenon in which the sun releases solar flares, energetic particles and/or coronal mass ejections (CME). These events are known as solar storms. In particular, if a CME is directed towards Earth, it can interact with the Earth’s magnetic field and cause geomagnetic storms. Under these circumstances extra currents, known as geo-magnetically induced currents (GIC), are created in the ground which can impact the electric grid.
