PLN Chief: Two Major Java Power Plants Hit by Technical Issues, One Restored

Direktur Utama (Dirut) PT PLN Darmawan Prasodjo revealed that two large power plants in Java owned by PLN’s partners, or independent power producers (IPP), recently experienced technical issues. One of the two plants has now been restored and is supplying electricity back to the Java grid. Darmawan explained that the supply of primary energy, which meets the specification requirements of both PLN and private power plants, began to normalise last week. This is considered to have further strengthened the resilience of the electricity system in Java. “The primary energy supply that meets the specification requirements of the plants, both PLN and those owned by our partners (independent power producers), started flowing last week and therefore strengthens the resilience of the electricity system in Java,” Darmawan told reporters at the Presidential Palace complex in Jakarta on Monday (22/6/2026). Darmawan stated that on Friday (19/6), two large power plants experienced technical issues. However, one has since been repaired. “Then on Friday we reported that two large plants owned by our partners experienced technical issues and were forced to exit the system. In response, last week we immediately deployed a PLN team together with our partners to carry out repairs. And there is good news, last night one large plant was successfully restored and synchronised with the electricity system in Java and has begun supplying power to the Java system,” he said. Darmawan expressed appreciation to the government, particularly Minister of Energy and Mineral Resources Bahlil Lahadalia, for the direction provided. He confirmed that improvements to the governance of the primary energy supply chain and the reinforcement of both PLN-owned and partner-owned plants are ongoing. “We are making all-out efforts 24 hours a day, 7 days a week, both in monitoring and mapping all our efforts so that the reliability improvements of the electricity system in Java can be maintained and even enhanced,” he stated. Darmawan apologised to the public for the inconvenience experienced since last week. He requested the public’s support so that the repair process can proceed smoothly. “We ask for prayers and support from the entire community so that our all-out efforts can be facilitated and run smoothly. And we greatly appreciate the support from the government and the cohesiveness of all our partners, both suppliers and power plant partners, so that together we can maintain reliability and ensure that energy supply going forward can run smoothly,” he said.
