Updated the post, here is, as it were, the money shot.

You can see that the frequency on the EU side goes low and then rises while the one on Baltic side goes high and then falls right before sync - I wonder if that was intentional! But in any case, you can very clearly see the point where they sync! so this experiment was as far as I am concerned a full success!

#BalticSynchro

Update #BalticSynchro: the #BalticStates #Estonia, #Latvia, and #Lithuania have disconnected from the #BRELL power grid and are now in island mode.

One line that provided interconnection service for #Estonia but runs through #Russia, was still running this morning. However, since 09:00 it looks like it has been disconnected, too.

Watch it live here:

You can clearly see the change in frequency noise when the grid was disconnected at 08:25 on Feb 8, 2025!
