From the little I know about power lines, events like this can cascade to half a continent.
Instead of 220V we got down to ~165V.
Internet outages on top (I assume some hardware failed since multiple counties were affected on the RDS network).
Edit.
Here's a power graphic: https://www.transelectrica.ro/widget/web/tel/sen-grafic/-/SE...
Seems Romanias production fell under the consumption at around 15:30
Water fell at that time, so maybe some hydro was shut down? We did have multiple floods reported yesterday.
But the incident started at 15:05, that was just a consequence of interconnects failing i think.
Are homes experiencing brownouts? Or is it only in the distribution system?
Industry may be still shut down, there was some chemical plant that had to perform an emergency shutdown which released some crap in the air. They say it's non toxic though.
That was my first reaction on /r/romania, too, but some commenter in there suggested that maybe the hydro power production went down as a result of the network not being available (no reason to "pump in" electricity if there's no available network to transport it).
I know this makes no sense and in other languages "news" has both singular and plural but that's English for you.
the romanian blackout is linked to the european one
