PLN confirms no more power outages in Java

The President Director of PT PLN (Persero), Darmawan Prasodjo, has ensured that there will be no more power outages in Java, as the company strengthens the electricity system to prevent such incidents from recurring.

“The condition of the electricity system, especially in Java, has seen no more rotational power outages since 21 June 2026,” Darmawan stated in Jakarta on Thursday during a Hearing Session with Commission XII of the Indonesian House of Representatives (DPR RI).

Darmawan noted that PLN will maintain and anticipate power outages in Java through a system reliability enhancement programme, planned in accordance with the directives of the Minister of Energy and Mineral Resources (ESDM).

According to him, the maintenance of the electricity system involves increasing the supply of medium to high-calorific coal—specifically 4,500 calories and above. This supply, allocated specifically for PLN from the Ministry of ESDM, amounts to 1.8 million tonnes “on top” of the existing supply for July.

“Furthermore, there will be 3 million tonnes per month from August to December, resulting in an additional supply capacity of 5 gigawatts (GW) above the existing 35.9 GW,” he said.

Darmawan added that this increase in electricity supply will make the electricity system in Java significantly more reliable.

Additionally, he continued, there will be an additional 4.6 GW of electricity supply in 2027. This addition will ensure that the system in Java, which previously experienced rotational outages, will immediately become much more dependable.

Darmawan acknowledged that, by volume, the percentage of national low-calorific coal production was previously smaller than high-calorific coal. However, over time, the production of low-calorific coal has increased, while the production of medium and high-calorific coal has been declining.

“With these measures, the energy supply constraints that previously occurred in Java have been corrected, and the rotational power outages have been successfully resolved,” he added.
