The electricity system in Java is improving, and rolling blackouts are being minimized, according to PT PLN (Persero) CEO Darmawan Prasodjo. The stabilization began Sunday following the restoration of a large power plant and the resumption of primary energy supplies to generators.
Darmawan provided this update on Monday, June 22, 2026, at the Presidential Palace complex in Jakarta. He noted that the electrical conditions in Java began to show improvement starting Sunday.
Why did the rolling blackouts occur in Java?
According to Darmawan, two large power plants owned by partners experienced technical issues on Friday. These issues forced both plants to exit the electricity system.
To address the disruption, Darmawan stated that PLN teams were deployed last week to work alongside partners on necessary repairs.
How is the power supply being stabilized?
The stability of the grid has been bolstered by the return of primary energy supplies. Darmawan noted that supplies meeting the required specifications for generators, from both PLN and Independent Power Producers, began flowing last week.
This influx of energy is intended to strengthen the overall resilience of the electricity system across Java.
What may happen next for the Java power grid?
As technical repairs continue, the frequency of rolling blackouts may continue to decrease. The stability of the system is likely to depend on the consistent flow of energy and the successful integration of remaining technical fixes.
