PLN Denies Java Blackout, Says Grid Remains Under Control
PT PLN (Persero) has denied reports suggesting that a total blackout has occurred within the Java electricity system. PLN ensures that the electricity system is currently operating and remains under control, despite disruptions occurring in several regions.
Gregorius Adi Trianto, Executive Vice President of Corporate Communications and CSR at PLN, stated that the disruptions were merely operational constraints that resulted in a reduction of electricity supply in certain areas.
“Responding to information circulating in the community regarding a blackout, PLN emphasises that such a condition has not occurred,” Gregornius said in a statement to Republika on Friday (12/06/2026).
He added that PLN continues to strive to maintain the reliability of the electricity system to ensure the supply to customers remains stable. The company is also taking remedial measures to minimise the impact of the ongoing disruptions.
Recently, residents in several areas reported power outages of varying durations. These conditions sparked speculation regarding the possibility of a widespread blackout across the Java power grid.
However, PLN maintains that the Java electricity system continues to operate normally and is in a controlled state. The company also expressed its apologies to customers affected by the supply disruptions.
Previously, the Ministry of Energy and Mineral Resources (ESDM) also refuted news linking the power disruptions to dwindling coal stocks for power plants. ESDM Ministry Spokesperson Dwi Anggia emphasised that the disruptions were caused by technical factors, not by coal supply issues.
Similarly, the Chairman of the Indonesian Mining Experts Association (Perhapi), Sudirman Widhy Hartono, confirmed that coal stocks and supplies for power plants remain secure. According to him, the coal supply for PLN continues to comply with the Domestic Market Obligation (DMO).
PLN has urged the public to follow information updates through the company’s official communication channels or local PLN units to avoid being influenced by unverified information.
