The Continental European Power System -- a large synchronized area stretching from Spain to Turkey and from Poland to Netherlands; encompassing 25 countries -- is experiencing a continuous system frequency deviation from the mean value of 50 Hz, and this since mid of January 2018. [...]
This average frequency deviation, that has never happened in any similar way in the CE Power system, must cease. The missing energy amounts currently to 113 GWh. The question of who will compensate for this loss has to be answered.
The decrease in frequency average is affecting also those electric clocks that are steered by the frequency of the power system and not by a quartz crystal: they show currently a delay of close to six minutes. [...]
For the system to properly function the frequency cannot go below 47.6 and above 52.4 Hz. At the extreme values of 47.5 (under frequency) and 52.5 (over frequency) all connected generation and devices would automatically disconnect. The average frequency of the period since mid-January 2018 until today was around 49.996 Hz.
