On the evening of Thursday 15 August 2024, the islands of Folegandros, Ios and Sikinos, which are supplied via medium-voltage underwater cables from Paros, experienced a complete electricity outage lasting about seven hours, from 20:30 until 03:30 the following morning, with the likely cause reported as unprecedented demand driven by high tourist numbers and high temperatures stressing the decades‑old interconnection lines. This event caused a major supply interruption on Sikinos and Folegandros, affecting the local cable network that links the two islands.
