I have heard that in Texas, they have transformers in their distribution hubs that are installed, but electrically disconnected. They are pre-installed spares. If something like that happens, then the backup can be physically connected to the long wire grid.
They also use these to swap out transformers for servicing. I don’t know if this is true. I did a little research on this after reading One Second After.

In Texas, we have our own electrical grid that is separate and distinct from the rest of the country. However, that would not help in an EMP issue (either natural or attack). The EMP fries the circuits, of anything connected, disconnected, powered up, or powered down, unless the device is hardened/protected against said EMP.
The EMP is a side effect, and potentially more devastating long term, than the nuclear explosion it could come from.
