Since the beginning of the Space Age the total length of high-voltage power lines crisscrossing North America has increased nearly 10 fold. This has turned power grids into giant antennas for geomagnetically induced currents. With demand for power growing even faster than the grids themselves, modern networks are sprawling, interconnected, and stressed to the limitâ€”a recipe for trouble, according to the National Academy of Sciences: “The scale and speed of problems that could occur on [these modern grids] have the potential to impact the power system in ways not previously experienced.”
So, basically, ninjas, in an attempt to protect the power grid from a solar storm, NASA is developing tech that could monitor the sun and adjust the grid as necessary to let key components remain un-damaged against powerful electrical surges.

Every hundred years or so, a solar storm comes along so potent it fills the skies of Earth with blood-red auroras, makes compass needles point in the wrong direction, and sends electric currents coursing through the planet’s topsoil. The most famous such storm, the Carrington Event of 1859, actually shocked telegraph operators and set some of their offices on fire. A 2008 report by the National Academy of Sciences warns that if such a storm occurred today, we could experience widespread power blackouts with permanent damage to many key transformers.
What’s a utility operator to do?
A new NASA project called “Solar Shield” could help keep the lights on.
“Solar Shield is a new and experimental forecasting system for the North American power grid,” explains project leader Antti Pulkkinen, a Catholic University of America research associate working at NASA’s Goddard Space Flight Center. “We believe we can zero in on specific transformers and predict which of them are going to be hit hardest by a space weather event.” -> Continue Reading at NASA Science
