GIANYAR, DEWATA.NEWS – A sudden power outage affected nearly all districts in Gianyar Regency and several other regions across Bali on Sunday night (Feb 22), raising concerns among residents due to the island’s reliance on electricity for daily activities, including internet connectivity.
According to data from PLN East Bali released on Monday (Feb 23), the disruption was not limited to Gianyar but also impacted other regencies and cities across the island.
PLN stated that the disturbance occurred at 7:39 p.m. WITA and was triggered by extreme weather conditions affecting the Java–Bali interconnection system. In response, the electricity protection system activated automatically to secure the network.
The protection mechanism functions similarly to a household circuit breaker but operates on a large-scale grid system. When a disturbance is detected, the system automatically releases part of the load to prevent wider impact and protect equipment.
In a press release from PLN’s Java–Bali–Madura Transmission Unit (UIT JBM), the disruption caused partial load shedding as part of the safety mechanism. The entire system was restored by 8:36 p.m. WITA.
System mapping showed affected areas across Badung, Karangasem, Gianyar, Tabanan, Jembrana, Denpasar, Buleleng, Klungkung, and Bangli. The most densely impacted regions were Badung and Karangasem.
In some areas, outages were feeder-specific, meaning they occurred only along particular distribution lines from substations to certain neighborhoods. Other areas connected to separate lines remained unaffected.
PLN operators and maintenance teams immediately conducted system security measures and grid maneuvers to stabilize voltage and accelerate restoration. Coordination between units was carried out to ensure a safe and gradual recovery of supply.
PLN UID Bali General Manager Eric Rossi Priyo Nugroho said the swift recovery was made possible by rapid personnel response.
“All teams moved quickly as soon as the disturbance was detected. Intensive coordination ensured that normalization could proceed safely and under control. By 8:36 p.m. WITA, Bali’s power system was fully restored,” Eric said.
The total recovery time was less than one hour. During the process, all power plants remained in safe condition and the system stayed stable.
PLN also addressed circulating rumors about planned rolling blackouts in Bali for one week, stating that the information is incorrect.
The company confirmed that no rolling blackouts are planned and that Bali’s electricity system is currently operating normally with sufficient capacity to meet customer demand.
PLN apologized for the temporary inconvenience experienced by some customers and stated that the incident will serve as an evaluation to further strengthen system resilience, particularly against extreme weather conditions.
Residents are advised to obtain official updates through PLN’s communication channels, including the PLN Mobile application and Contact Center 123, and to avoid unverified information.
“The reliability of electricity supply in Bali remains a priority to support community activities, tourism, and regional as well as national economic growth,” Eric added.
