Java's Power System Recovery Underway as Coal Supplies Resume

Indonesia's state electricity company, PT PLN (Persero), is actively working to restore the electricity system across Java following disruptions. The crucial step in this recovery involves the supply of medium-calorie coal, which has begun to reach several strategic power generation facilities.

Darmawan Prasodjo, CEO of PLN, expressed gratitude for the government's support, particularly from the Ministry of Energy and Mineral Resources. He stated that the government's allocation of medium-calorie coal is vital for speeding up the normalization of the power supply. "We appreciate the support from the government, in this case, the Minister of Energy and Mineral Resources Mr. Bahlil Lahadalia, the Directorate General of Electricity, and the Directorate General of Mineral and Coal. With the allocation of medium-calorie coal and direction from the Minister of Energy and Mineral Resources, PLN will make various improvements to ensure the electricity supply process runs smoothly," Darmawan said in a press release on Friday evening, June 19, 2026.

The coal shipments are directed to both PLN-owned power plants and those operated by Independent Power Producers (IPPs) that are integrated into Java's electrical grid. Specific plants receiving these supplies include PLTU Lontar, Labuan, Suralaya (Units 1-5), Jawa 7, Jawa 9 & 10, and Indramayu in West Java, as well as PLTU Paiton (Units 1 & 2, Unit 9), Rembang, Pacitan, and Tanjung Awar-Awar in East Java.

PLN is also expediting the signing of contracts with coal suppliers who have been assigned by the government. This measure aims to guarantee the prompt delivery of primary energy to power plants. Furthermore, PLN is collaborating closely with the Directorate General of Mineral and Coal to streamline the contract and distribution processes. In parallel, PLN is addressing technical problems at two major IPP plants that had temporarily disconnected from the Java power system, deploying technical teams to expedite repairs and bring them back online.
