Time for a short summary of the mains frequency measurements of 2022. As shown by the following box plot, there is no indication of a critical deviation from the 50 Hz nominal frequency, "critical" defined as being outside the range [49.8 Hz, 50.2 Hz].
Mains Frequency (f) -- Summary Week 51/2022:
min(f) = 49.889 Hz
max(f) = 50.109 Hz
mean(f) = 50.0006 Hz
99 % confidence interval of the mean = [50.00059 Hz,50.00063 Hz]
Measured in Southern Germany (Plochingen).

Mains Frequency (f) -- Summary Week 49/2022:
min(f) = 49.898 Hz
max(f) = 50.115 Hz
mean(f) = 49.9998 Hz
99 % confidence interval of the mean = [49.99981 Hz,49.99985 Hz]
Measured in Southern Germany (Plochingen).

How to interpret these numbers:
+ Normal operation area: [49.8 Hz,50.2 Hz]
+ Minimum/maximum instantaneous frequency after loss of generation/load: [49.2 Hz,50.8 Hz]
Higher deviations lead to load shedding and possible grid failure (#blackout).
Mains Frequency (f) -- Summary Week 48/2022:
min(f) = 49.893 Hz
max(f) = 50.098 Hz
mean(f) = 50.0003 Hz
99 % confidence interval of the mean = [50.00025 Hz,50.00029 Hz]
Measured in Southern Germany (Plochingen).
