PLN Watch urges public support for electricity restoration in Sumatra

Chairman of PLN Watch, KRT Tohom Purba, has urged the public to support efforts to restore the electricity system following a widespread blackout in parts of Sumatra. Tohom stated that PLN’s swift actions, in collaboration with Bareskrim Polri, demonstrate a serious, professional, and transparent handling of the national power disturbance. “If preliminary investigations find no signs of human intent, the public must view this matter objectively. Modern power systems are heavily influenced by technical factors and extreme weather. The most crucial step now is to support recovery and strengthen the system moving forward,” Tohom said in a statement on Sunday in Jakarta. According to Tohom, large-scale blackouts can cause domino effects on transmission and generation networks, particularly when disruptions occur in the main interconnection backbone. He noted PLN’s rapid response in restoring power to millions of customers in a short timeframe as evidence of growing preparedness of national power personnel and infrastructure. “In a system as large as Sumatra, transmission faults can create highly complex load imbalances. However, PLN’s ability to swiftly implement phased recovery demonstrates improving engineering and mitigation capabilities,” he added. Tohom believes the incident should accelerate the modernisation of the national power grid, including strengthening 500 kV and 275 kV backbone transmission lines as per government directives. He stressed that Indonesia needs a power system that is not only robust but also adaptable to extreme weather and rising national energy demands. “Energy sector transformation isn’t just about building power plants. It requires strengthening transmission, digitalising network monitoring, predictive maintenance, and layered protection systems to prevent cascading failures,” he said. Tohom urged the public to allow PLN and authorities to complete thorough investigations without spreading speculation that could worsen the situation. He reminded that stable electricity supply directly impacts economic activity, public services, industry, and national security. Previously, police deployed teams to investigate the cause of the Sumatra blackout. Initial checks at the 175-176 kV transmission line disconnection point in Tempino Village, Mestong District, Muara Jambi Regency, found no indications of human intent in the conductor failure. PLN also indicated that the outage was likely triggered by severe weather affecting the 275 kV Muaro Bungo–Sungai Rumbai transmission system, causing a cascading failure across Sumatra’s power network.
