I am currently in my work office in Madrid, main building has electricity so I guess they have some backup generators, the kitchen however is out of service.

According to local newspapers metro network, airport and traffic lights are all down

most office buildings have gas(methane) generator backup.

Dunno about Spain/portugal, but in North America they’re usually just for elevators/alarms, partial hallway lighting & maybe water pumps (for firefighting).

Maybe a tech company with servers will pay extra for full backup, but it’s not typical.

Without fail, during every grid outage, some will fail to start and there will be elevator rescue calls throughout the city.
