How do you phase lock the French grid to the Belgian Grid to the Dutch

Are they phased locked? I don't know.

Most of Europe is phase locked.

Fascinating. I would have thought they would have avoided that due to
the buggeration factor.

Is there a supergrid organisation that manages this euro-grid at the top
level then?

I really don't know.

I think each nation has its own but presumably they have to phase lock
with each other before they start interconnecting

Germany Austria and Switzerland also operate another interconnected
network at 16.7Hz which is what most of their electrified railways
use. The lower frequency suited the simple motors and control
available when the systems were first introduced in the early part of
the 20th century.
