PLN Reveals Two Major Java Coal-Fired Power Plants Suffer Technical Faults

Jakarta (ANTARA) - PT PLN (Persero) President Director Darmawan Prasodjo has revealed that two coal-fired power plants (PLTU) on Java Island are experiencing technical faults, leading to rolling blackouts across the region. “We are facing challenges; there are technical issues at two major power plants in Java owned and operated by our partners,” Darmawan said in a voice recording confirmed by PLN on Saturday. He explained that the technical faults at the Independent Power Producer (IPP) plants caused both facilities to be disconnected from Java’s electricity system. In response, PLN and its power plant partners are deploying teams to repair the two large PLTUs. Darmawan expressed hope that the repairs would proceed quickly and smoothly, allowing the plants to recover and resume supplying electricity to the Java grid soon. “Once again, we sincerely apologise for the disruption that has resulted in rolling blackouts across Java,” he said. He also expressed appreciation to the government and all parties assisting PLN in restoring the electricity system. Rolling blackouts have occurred in several areas since early June 2026. According to ANTARA’s monitoring, parts of East Java, particularly Surabaya, Sidoarjo, and Gresik, have frequently experienced power cuts over the past week at varying times. Some areas have suffered sudden blackouts lasting between two and five hours a day. Last week, several main roads in Surabaya also experienced hours-long power cuts extending into the night, posing significant danger to motorists. Executive Vice President of Corporate Communications and TJSL at PLN, Gregorius Adi Trianto, stated that to maintain supply reliability for customers, PLN is implementing limited and measured load management in several areas. “This load management is temporary and will be gradually halted as the supply situation improves,” Greg said.
