Are you sure this is still the case ?

Here in the "NordPool" area in nothern europe, 50Hz average went
out the window with the deregulation of the electricity grid because
nobody wanted to be forced to provide the extra power during one
season to gain back what was lost during the other.

And before that, the short term variations were on the order of
a year...
