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!


I didn't know / imagine that (or guess why)?


AIUI short-distance undersea interconnectors are sometimes AC, but
long-distance ones are almost always DC, because they experience
significant capacitance* losses if AC due to being surrounded by an
earthed conductor, i.e. salt water.

*but might be inductance. IANAE

Not usre there are ANY undersea AC links

It is capaacitance that kills - power factor is vile and that leads to
large out of phase currents which heat the cable up
