Spain and Portugal limp back to normal after crippling outage

Power restored for nearly all users, as the search for answers continues

- 

Spain and Portugal were returning to some semblance of normality early yesterday, with questions remaining about what caused one of Europe's worst blackouts in years across the Iberian peninsula a day earlier.

Spanish power supplies were back to nearly 100 per cent capacity at around 7am in Madrid, and urban trains were slowly returning to regular service, according to operators.

Portugal said power has been restored for all users, and grid operator REN said the network is "perfectly stabilised."
