England losing grid power will have no impact on those souls living anywhere else.
In 2003 the US had a grid outage that impacted a larger area than GB in size and I was 30 miles from the edge of the dark zone and except for the news reports knew nothing was out of sorts.
Many areas still produce power locally and have no concept of being part of a "grid" as you know it.
It is going to be a real shock for all the folks that think the whole world has returned to the technology of the dark ages to find that many of the towns in Russia still have portable nuke reactors in full operation, many communities have hydro stations operating, and some of the steam plants in other areas have reverted to using locally mined coal.
If you do not get your systems patched together, up and running within a short time you will probably become known as a colony of those areas.
