In 1960, the original Korčula-Lastovo submarine power cable was laid and energised, connecting the island of Lastovo to the Croatian mainland electricity grid for the first time. The route runs from uvala Stratinčica on Korčula (near Brna) to uvala Korita on Lastovo (near Zaklopatica), thence underground to the 10 kV Sozanj switchgear serving the local distribution network on Lastovo. The cable is a 10 kV three-core submarine cable of approximately 14.75 km subsea length. This 1960 installation marked the end of Lastovo's electrical isolation (the island had previously been served from circa 1930 by a small local public generator per Razvoj elektrifikacije Hrvatske). A pre-1960 cable attempt had been laid but was damaged during installation and never energised, subsequently extracted and scrapped (HEP Vjesnik 224, Sept 2009). Since 1995 the 1960 cable has served as backup feed, with the primary feed supplied via a newer 35 kV (operated at 20 kV) cable on the Gršćica-Zarebra route (separate project).
