There's a high probability that the blackout was caused by a lighting strike according to Angel Crespo, the chief of of the PR firefighters:
http://www.elnuevodia.com/english/engli … t-2244424/I am wondering why one lightning strike (or whatever may have caused the beginning of the problems) can put the grid down on all of the island.
O.K. I may be spoiled having lived in the two countries with the least blackouts world wide (The Netherlands and Germany) but come on, there should be at least some redundancy built in the system, right? If a single lightning strike can put down the grid on the island something is structural wrong with the design of the system.
Now, please don't think I'm surprised. I've lived here for 15 years now and I know that a little wind or some heavy rain will cause power outages all over the place. I hope that this "apagón" (huge blackout) will lead to measures to improve the system but somehow I have a feeling that everything will stay like it was...
