That is true, but it hasn't stopped most of Europe's electricity
networks from being synchronised, and not just between members of the
EU. See
http://en.wikipedia.org/wiki/Synchronous_grid_of_Continental_Europe
"The synchronous grid of Continental Europe is the largest synchronous
electrical grid (by connected power) in the world. It is interconnected
a single phase-locked 50 Hz mains frequency electricity grid that
supplies over 400 million customers in 24 countries, including most of
the European Union."
There are many undersea HVDC connections around Europe and some
proposals for long distance HVDC lines.
