AFAIK the continental synchronous area frequency is long-term-synchronized to atomic time (i.e. the cumulative grid time must stay within X seconds of the reference clock).
Looking at the (partial) graph suggests that the south-east part ran faster for the entire duration of the disconnection.
Does this mean grid-synced clocks in the south-east part are now permanently ahead of the atomic reference, or are they planning a mitigation (which I assume would have to mean disconnecting again and running the SE part slower for a bit)?

That's the standard procedure. Maintaining an exact frequency can be hard, but counting cycles is easy. So the frequency will slew to slowly compensate back. Edit: Here's a Tom Scott video on a UK–Continental divergence that happened a while back: https://www.youtube.com/watch?v=bij-JjzCa7o https://www.youtube.com/watch?v=bij-JjzCa7o
- garaetjjte 6y agoUK is connected through DC lines, so frequency is independent. In this case they would have to separate the grid again to be able to correct this.
