‘An official report prepared by John Kappenman, an independent consultant, was commissioned by The Oak Ridge National Laboratory in 2010. The report is summarized in The JASON report on Impacts of Severe Space Weather on The Electrical Grid, project number 13119022.
JASON is an independent group of some 60 scientists that advises the United States government on science and technology that could have national implications. It is run by the non-profit making MITRE Corporation in Virginia.
There is a massive amount of information in the report which was published in November 2011. For the technically minded, transformers are discussed in detail, highlighting the problems that space weather impacts could, and does have on them. There are examples from around the world of the damage caused to electrical grids when a coronal mass ejection hits the Earth. There are details of different types of space weather, their effects and likely outcomes of such incidents.’
