Solar flares and power outages
Solar flares can lead to power outages through geomagnetic storms that induce electric currents in power lines, potentially overloading electrical equipment1. As we approach peak solar activity in 2025, the risk of such outages may increase, with concerns that a significant solar storm could cause widespread disruptions2. To mitigate these risks, understanding the potential impacts and preparing accordingly is essential3.

6 FAQs about [Solar flares and power outages]
Will a solar storm cause widespread outages & damage?
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.
Do solar flares affect flight time?
One study indicates that during solar flares, flight departure delay time increases on average by 21% (eight minutes). Power outages A major coronal mass ejection in March 1989 (solar cycle 22) significantly interfered with the U.S. power grid and caused a nine-hour power failure in Quebec, costing US $13.2 million.
What is a solar flare?
A solar flare is an intense burst of radiation, or light, on the Sun. These flashes span the electromagnetic spectrum — including X-rays, gamma rays, radio waves, and ultraviolet and visible light. Solar flares are the most powerful explosions in the solar system — the biggest ones can have as much energy as a billion hydrogen bombs.
Could solar storms damage the electric grid?
The possibility exists that, without protection, the electric grid is vulnerable to large solar storms that could damage large portions of the grid in ways that could conceivably take years to fix. Lights of North America, Central America, and Caribbean Islands as sunlight hits the far right edge of the globe. NASA Image
Are solar flares a gray swan event?
Solar flares epitomize the concept of a gray swan event. Unlike black swans, which are unpredictable and exceptionally rare events with severe consequences (such as the 2011 Tōhoku earthquake), gray swans like solar flares are not entirely unforeseen.
What happens during a solar maximum?
During the solar maximum, the sun unleashes powerful forces, including solar flares and coronal mass ejections, which can significantly disturb Earth’s magnetosphere, leading to geomagnetic storms that may disrupt communication systems, power grids and satellite operations.
