Things happen.

Dunno.

I'll try to expand some information, for you and Martin.

In Andalucia and Extremadura (south and west of Spain) there are lots of 
rural areas that can accommodate huge solar plants, so lot of 
generation. On the other hand they don't have much of industry (not 
traditionally developed areas), so not much of demand (relatively).

On the other hand, Madrid (centre of Spain) and Cataluña (north-east) 
have a lot of industries and less solar/wind generation.

Nuclear generators are also mostly in the periphery, near the sea or big 
rivers. Not in the very densely populated Madrid (map here: 
<https://www.miteco.gob.es/es/energia/nuclear/centrales/espana.html>).

Gas or oil generators? Also they don't abound in Madrid, the fuel has to 
be transported there.
