Well, the test range where the built the test long-distance power electrical lines was at that time fairly in the middle of nowhere. However, the secondary EMP effects proved much stronger than anticipated, and it blew out over 1,000 km of shallow-buried power lines and caused the power plant at Karaganda—the one nearest to the point of the high altitude detonation—to literally catch on fire.

With power stations, it’s all about the large transformers that take years to replace. If those are not dealt irreparable damage, then the other stuff can and will be repaired in fairly short order. Large transformers were not destroyed in either Kazhakstan or Hawaii, which is a very hopeful sign.
