        "summary": "PLN states that the Sumatra blackout on 22 May was caused by severe weather that damaged transmission lines, leading to a frequency drop and cascading outages. The network was restored within about two hours, with hydro and gas plants providing rapid support and thermal plants requiring longer to come online; hundreds of PLN staff supported recovery across Jambi, West Sumatra, Riau, North Sumatra and Aceh.",
        "content": "<p>Jakarta \u2014 PT PLN (Persero) said that the widespread blackout in\nSumatra on Friday, 22 May, from 18:44 Western Indonesian Time (WIB), was\ncaused by severe weather which subsequently affected part of Sumatra\u2019s\npower transmission system. \u201cThe fault on a transmission corridor caused\nan outage that spread to part of Sumatra\u2019s transmission system,\nresulting in a drop in frequency due to heavy load on the generating\nplants and triggering a domino effect of disturbances in several\nregions,\u201d PLN President Director Darmawan Prasodjo said in a statement\nconfirmed by ANTARA from Jakarta on Saturday. Darmawan said that from\nthe moment the fault occurred at about 18:44 WIB on Friday 22 May, PLN\nimmediately moved to inspect and restore the power system. He explained\nthat within about two hours the disturbed transmission network had been\nrecovered. After the transmission network was restored, Darmawan\ncontinued, PLN\u2019s main focus was to re-operate the generation plants that\nwere previously affected and then re-synchronize them with the\ntransmission system that had been prepared. He explained that the\nstarting-up of the plants was done systematically and gradually while\nprioritising system safety. Hydro and gas-based plants can immediately\nhelp supply the system as a rapid response to accelerate the initial\nrecovery. \u201cMeanwhile thermal plants such as PLTU require more time,\nbetween 15 to 20 hours from start-up, synchronisation, and full\noperation,\u201d he said. Recovery was carried out simultaneously starting\nfrom the transmission, switchgear, to the power plants in the Sumatra\nelectricity system. To support the process, PLN deployed hundreds of\npersonnel working 24 hours in affected areas ranging from Jambi, West\nSumatra, Riau, North Sumatra and Aceh. (ANT)<\/p>",
