ESDM: Saguling Hydroelectric Power Plant Already Prepared to Stabilise Jamali Electricity Supply

Jakarta — Indonesia’s Deputy Minister of Energy and Mineral Resources, Yuliot, has confirmed that the Saguling hydroelectric power plant (PLTA) in West Bandung, West Java, has been thoroughly prepared to maintain the reliability and electricity supply across the Java, Madura, and Bali (Jamali) region during the Eid al-Fitr 1447 Hijriah holidays.

“Looking at the potential for disruptions ahead, it is actually very minimal,” Yuliot stated in an official statement received in Jakarta on Tuesday.

Following a direct inspection of the operational readiness of Saguling PLTA in West Bandung, Yuliot said the government is ensuring that the condition of Indonesia’s national electricity system, particularly in Jamali, remains secure with adequate power reserves to meet public demand.

“Regarding electricity supply, we want to verify the overall readiness of Saguling PLTA in supplying the Java-Bali electricity system,” said Yuliot, accompanied by officials from PT PLN (Persero), Indonesia’s state-owned electricity company.

Saguling PLTA, which harnesses the flow of the Citarum River, plays a crucial role in Indonesia’s national electricity system, particularly in the Java-Bali region. In addition to supporting peak loads in the Java-Bali system, the power plant, with a capacity of 4x175.18 MW, also functions as a system frequency regulator by applying load frequency control (LFC).

During the Ramadhan and Eid al-Fitr alert period from 12-31 March 2026, projections indicate a peak load of 47,198 MW, whilst supply capacity reaches 51,608 MW, leaving a total reserve of 4,410 MW.

“With the availability of supply and demand still maintaining a reserve of 9.3 per cent or 4,401 MW, we can confirm that the reserve is sufficiently reliable,” Yuliot said.

On 21 March 2026, Eid al-Fitr day, the National Command Centre projects a peak load of 35,017 MW and supply capacity of 51,967 MW, resulting in a total reserve of 16,950 MW (48.4 per cent).

These projections demonstrate that although the peak load on Eid al-Fitr day increases by 5.46 per cent compared to 2025, it remains 29 per cent lower than normal days.
