Portugal had a major power outage in almost the entire country. And apparently, so did other European countries. From what I heard, it's due to something going on with the atmosphere and it started on Spain.
When Portugal had electricity back, it started on the North and took a while to get down there. Though there's still stories of airports on hold and stores being robbed, at least in some areas.
During this time, me and my family had to cook some food because of the fact that the fridge stopped working. We still had some phone battery/data but had to save a bit of it just in case.
As of now, it's back. A big lesson here is to prepare and be carefull as usual.
