In the early 1960s, submarine cable installation began to connect Greek islands to the interconnected transmission system, including laying 15 kV submarine cables to link the Argosaronic islands such as Hydra to the grid.
In the early 1960s, the island of Hydra, along with other Saronic Gulf islands, was interconnected using 15 kV submarine cables, completing its cable-based connection to the Greek interconnected transmission system and enabling more secure and economical electricity supply for the following decades.
In the early 1960s, the Saronic Gulf islands, including Hydra, were interconnected to the mainland electricity system via 15 kV submarine cables, providing a long-term solution for the islands’ power supply and marking the start of full commercial operation of the Hydra interconnection.
