        "summary": "A UMY power systems expert has urged PT PLN to conduct urgent audits and inspections of Sumatra's power grid following the May 2026 blackout, warning that without structural technical evaluations, the grid remains vulnerable to recurring disruptions. Key recommendations include real-time monitoring systems, flexible power generation sources, and energy storage solutions to manage increased renewable energy integration, with the expert stressing that delaying these measures is no longer viable.",
        "content": "<p>YOGYAKARTA (ANTARA) \u2013 UMY power systems expert Rahmat Adiprasetya Al\nHasibi has stated that a thorough audit of Sumatra\u2019s power grid\nprotection system must be the first and most urgent step for PT PLN\n(Persero) following the massive blackout on 22-24 May 2026.<\/p>\n<p>Rahmat, speaking in Yogyakarta on Friday, warned that without\nstructured technical evaluations, Sumatra\u2019s power system would remain\nvulnerable to recurring disruptions.<\/p>\n<p>\u201cThe first and most urgent step is to audit the current protection\nsystem settings, followed by evaluating the frequency response schemes\nfor each generator in Sumatra\u2019s grid,\u201d Rahmat said in a statement.<\/p>\n<p>He added that PLN\u2019s response must not stop at merely stating that\nsimilar incidents will not recur.<\/p>\n<p>In the medium term, Rahmat urged the state-owned power company to\nconduct comprehensive inspections of transmission right-of-way (ROW)\ncorridors \u2013 the safe zones along high-voltage transmission lines that\nmust be clear of physical obstacles and vegetation.<\/p>\n<p>\u201cSuch inspections are crucial, especially for transmission lines\nforming the backbone of Sumatra\u2019s interconnected system,\u201d he added.<\/p>\n<p>PLN should also immediately re-simulate various major disruption\nscenarios, particularly during peak load conditions, to develop a more\naccurate risk map for preventive measures.<\/p>\n<p>For the long term, Rahmat called for PLN to invest in advanced grid\nmonitoring systems, such as Wide Area Measuring System (WAMS), which can\nmonitor power grid conditions in real-time across vast geographical\nareas.<\/p>\n<p>This technology allows operators to detect potential instability\nearly before it escalates into uncontrolled large-scale disruptions.<\/p>\n<p>He also stressed the importance of increasing the share of highly\nflexible power generation in Sumatra\u2019s energy mix, such as hydropower\n(PLTA) and gas-fired plants (PLTG), which respond more quickly to load\nchanges.<\/p>\n<p>\u201cIf renewable energy penetration increases, system variability will\ngrow. Therefore, we need flexible generation and adequate energy\nstorage. This is no longer a choice that can be postponed,\u201d Rahmat\nsaid.<\/p>",
