Darmawan Prasodjo, president director of state electricity firm Perusahaan Listrik Negara (PLN), said early indications were that a disruption in subsea cables was the cause of outage.
A power outage hit a number of regions of Bali from 4pm on Friday, said state utility Perusahaan Listrik Negara.
The island's airport was also impacted but inbound and outbound flight traffic continued using backup generators, the airport's general manager Ahmad Syaugi Shahab said in a statement, although several departures had experienced delays.
Images shared on social media showed road traffic holdups in Bali as a result of the outage and long lines at the airport check-in counters.
Power began to return a few hours after the blackout.
"State utility PLN managed to restore most of the electricity supply in Bali," the spokesperson of President Prabowo Subianto, Prasetyo Hadi said in a statement after calling PLN's CEO.
"God willing, power connection in Bali will be fully restored tonight (Friday night)," he said.
PLN prioritised restoring electricity to key infrastructure such as government offices, hospitals, the airport, as well as hotels, said Prasetyo.
Bali is Indonesia's main tourist hotspot, with 6.3 million foreign visitors in 2024 according to the island's statistics bureau.
