The Department of Homeland Security sponsored a study on the threat of abnormally large Coronal Mass Ejections on our power grid. They estimated that for only $100 million dollars, our power should be protected from severe geomagnetic storms.

Kapppenman (2010) Worst-Case Scenario for Grid Damage by Geomagnetic Storms
A report prepared for Oak Ridge National Laboratory by John Kappenman an independent consultant, examines the vulnerability of the U.S. electric grid to severe solar storms. The report has generated great interest in government and the public, largely owing to the projected scenario of catastrophic damage, including:
- More than 300 EHV transformers destroyed
- 130 million people lacking power for several years until damaged high-voltage transformers are replaced
- 1-2 trillion dollars of economic loss.
