Overnight into Tuesday, about 90% of power has been restored to Spain's national grid and lights have come back on in the Portuguese capital of Lisbon
Probably technical. A too big variation (hertz, voltage in this case?) can trigger an automatic disconnection from other networks. The cut in France was quick to fix as soon they isolated the Spain network and rerouted/decreased/increased production from others part of Europe.
Here the blackout only lasted two hours. There were people stuck in elevators and trains, and traffic jams. Buses were overloaded for the remaining day as trains were not running. During the blackout I stored some drinking water and checked that the gas cooker was working in case it would last longer.
No power cuts here. The building has solar panels and when they don't get enough sun we have the hydroelectric dam in the Rhine to fall back on.
I had 5 Colleague's from Portugal who lost connection when it happened, must have been a calm day for them work wise
I'm not in Spain or Portugal, but Pittsburgh in the US was hit by massive storms yesterday. 40% of the city and outskirts lost power. We're at about 20% down now, including myself. Power will likely be out for 3-5 more days.
It looks like they're mostly back now.
