Large parts of Greece were plunged into darkness following a power cut caused by substation fire.
The blackout occurred in the early hours of Monday 8 February after a fire broke out at a high-voltage power station in Aspropyrgos, a suburb in the west of Athens.
Grid operator ADMIE revealed a technical failure as the probable cause of the fire. Preliminary assessments by the local fire service pointed the finger at a short circuit.
It is thought around one million people were left without electricity, not just in the capital but in Piraeus and the Peloponnese peninsula.
ADMIE claimed power was restored within an hour of the blackout.
