Several parts of central Athens, Piraeus and the capital's western suburbs were left without power late on Tuesday morning, due to a problem caused by human error at the Independent Power Transmission Operator S.A (ADMIE) Extra-High Voltage Substation in Rouf.
ADMIE President and CEO Manos Manousakis said the power, which failed at 11:35, was restored just before noon.
After investigating the cause of the outage, ADMIE said it had found no malfunctioning equipment and that none of the staff had been in any danger, attributing the problem to mistaken handling. The error was corrected at 11:42, at which point the process of restoring power to the Hellenic Electricity Distribution Network Operator (HEDNO) distribution network began and was completed at 11:55, when power supply problems were fixed.
Power in Athens was also cut last week, due to damage to the Public Power Corporation's medium-voltage network.
