In the end, the real issue with EMP is the power grid. The power grid will largely go off-line, and certainly will break grid tie-points.
We need to figure out how to bring power grids up hot from a cold state more quickly. It is an incredibly complex problem, but one that can be solved, (and practiced).
That may be a good way to get new power transmission paths past environmentalists - use the "EMP" hardening argument.
Power companies, transmission companies would do well to preposition all the spares needed to make grid recovery a faster process.
