Real-time AC frequency on the Estonian grid, which has been part of the Continental European Synchronous Area since 9 February 2025. The whole CESA shares one frequency in real time — Estonia and Portugal see the same number. Sourced from Elering, downsampled to 5-min mean and refreshed hourly.

Frequency stayed in the 49.930–50.050 Hz band (168 samples).

The largest deviation from the 50.000 Hz nominal was 0.070 Hz at 10:00.
