Spain admits solar power could be to blame for nationwide blackouts: Mystery over cause of outage grows as top court opens 'sabotage' probe

Spain's grid operator admitted today that solar power could be to blame for Monday's blackout chaos, as mystery continues to surround what caused the historic power outage across the Iberian Peninsula.

Red Eléctrica's System Operations Chief Eduardo Prieto told a news briefing the electricity system was hit by a dramatic power generation loss in southwestern Spain, that caused instability in the system that led to its disconnection from the French grid.

He said it was quite possible that the affected generation was solar, but it was to early to say for sure. Prieto said the system was now stable and working normally.
