TEMPO.CO, Jakarta - President Director of PT PLN (Persero), Darmawan Prasodjo, stated that disturbances in the undersea cable distribution system were indicated as the cause of the blackout in Bali on Friday, May 2, 2025. However, this issue is still a preliminary indication.
"The certainty of the cause is still being investigated and not due to a cyber attack or other factors," Darmawan said in a written statement on Saturday, May 3, 2025.
Darmawan conveyed that electricity has now been restored in Bali. He said all PLN customers in Bali have been able to enjoy electricity normally since early this morning at 03:00 WITA (Central Indonesia Time). "We apologize for the inconvenience that occurred," he said.
Although the electricity has been restored, Darmawan mentioned that PLN personnel continue to be on standby in the field to ensure that the electricity supply in Bali is fully recovered by 100 percent. Public service sectors, such as hospitals, airports, ports, and other commercial centers, are a priority. "We are making maximum efforts while evaluating and strengthening the electricity system to ensure that all customers can continue to enjoy reliable electricity as usual," Darmawan said.
The mass blackout in Bali occurred yesterday around 16:00 WITA. This incident also impacted flight services at Ngurah Rai Airport. General Manager of Ngurah Rai Airport, Ahmad Syaugi Shahab, said there were several flight delays due to the transition of power sources from PLN to the genset, which affected the system transition time for restarting. However, airport services continued to operate with a backup power supply from the genset.
