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.
