Concern that a solar storm might cause widespread outages and damage is valid and documented. As we approach peak solar activity in 2025, solar storms may increase in frequency and intensity. An event of similar intensity to the Carrington Event will damage more than our power grid.
The current 11-year solar cycle is reaching peak activity with sunspots, solar flares, and coronal mass ejections. Since the 1700s, we have counted and documented these cycles. In mid-March 1989, a geomagnetic storm struck the earth’s northern hemisphere, causing a 9-hour power outage in Quebec.
One of the most effective ways to safeguard against power outage caused by solar flare is to have alternative power sources in place. Installing rooftop solar panel systems with battery storage, for example, allows you to generate and store your own energy, independent of the grid.
The duration of a power outage caused by a solar flare can vary widely, from a few minutes to several hours or even days, depending on the severity of the flare and the resilience of the power grid. Discover the science behind solar flare power outage here.
These storms can induce electrical currents in the Earth's atmosphere, which in turn create fluctuations in the power lines that make up our electrical grids. The rapid changes in magnetic fields caused by geomagnetic storms can overload transformers, trip circuits, and even cause widespread blackouts.
This allows you to prepare for a possible power outage by charging devices, securing alternative power sources, and finalizing any last-minute preparations. On a larger scale, power companies can invest in reinforcing grid infrastructure to make it more resilient to solar flare impacts.
