Attica Regional Governor Rena Dourou asked that a state of emergency be declared for Hydra, since the island has been without electricity and water since 5:30 am on Sunday.
According to the Athens News Agency, the governor said the blackout is due to a technological problem not allowing for electricity and water and called on the General Secretariat for Civil Protection to declare a state of emergency for the island.
The Public Power Corporation has sent two power generators to the island and the Greek Navy sent water tank vessel Stymfalia for water supply.
Hydra Mayor Giorgos Koukoudakis said that the causes of the blackout are still unknown and that he was told by PPC that electricity supply would be restored by Monday afternoon.
Hydra business owners complained that the financial damage is great since the blackout occurred at the peak of the tourist season. One restaurant owner said on ANT1 television that he was forced to send away about 100 customers on Sunday and another 70 who had made reservations for Monday. In addition to this, he also had to throw away all the food he had in the restaurant.
According to the ANT1 report, many tourists tried to book tickets to leave the island on Sunday evening.
