Seems surprising.

I'm not sure if the continental grid is kept synchronised across all
countries. In the UK, any daily lag is usually fixed overnight.

Good job the interconnctors are DC!

It's exactly *why* they're DC as I understand it, the difficulty of
synchronising our grid with the French grid.

For longer cables DC makes sense for other reasons but for the 25 odd
miles across the channel I'm pretty sure it was the synchronisation
issue that was the reason for using DC.

Weren't they originally huge mercury arc rectifiers or is that just my
wierd imagination? :-)
