        "summary": "PLN states that power-supply constraints on Sumbawa Island, West Nusa Tenggara, have been alleviated following the operation of the 30 MW PLTMG Sumbawa II gas-engine power plant. Capacity has risen to around 191.91 MW with a 20% reserve margin, and the entire Tambora system is now connected from west to east; PLN plans to add a further 60 MW by 2027 to strengthen reliability.",
        "content": "<p>Mataram (ANTARA) \u2013 The State Electricity Company (PLN) says that\nconstraints in electricity supply on Sumbawa Island, West Nusa Tenggara\n(NTB), are being resolved thanks to the operation of the gas-engine\npower plant (PLTMG) Sumbawa II with a capacity of 30 megawatts.<\/p>\n<p>General Manager of PLN\u2019s NTB Regional Development Unit, Rizki\nAftarianto, said the Tambora System\u2019s capacity before the plant began\noperating was around 168 megawatts, with a peak load of 157\nmegawatts.<\/p>\n<p>\u201cElectricity sufficiency on Sumbawa Island is now stronger.\nPreviously, the supply in the area was still short, so our customers\u2019\nneeds, including the industrial sector, could not be met optimally,\u201d he\nsaid in a statement in Mataram on Wednesday.<\/p>\n<p>Rizki noted that the electricity capacity on Sumbawa Island increased\nfrom 168 MW to 191.91 MW after the gas-engine plant began full operation\nin December 2025.<\/p>\n<p>A power reserve of 20 percent of total electricity demand has made\nenergy supply more reliable than before, when there were power\nconstraints.<\/p>\n<p>He said that a large electricity reserve is important to maintain\nenergy supply stability, especially amid growing economic and industrial\nactivity.<\/p>\n<p>Sumbawa Island is now developing as a new industrial area in West\nNusa Tenggara, with the presence of a smelter project, the gold mining\nsector, shrimp farming, and the tourism and hospitality sectors.<\/p>\n<p>\u201cElectricity supply is now considerably more ample and can meet both\nindustrial and public needs well,\u201d Rizki said.<\/p>\n<p>He further confirmed that the additional capacity from PLTMG Sumbawa\nII has reached the entire Tambora System, covering West Sumbawa Regency,\nSumbawa Regency, Dompu Regency, Bima City, and Bima Regency.<\/p>\n<p>The Sumbawa Island electricity system is now connected from west to\neast, resulting in more stable and evenly distributed energy.<\/p>\n<p>By the end of 2027, the state-owned electricity company plans to add\nanother 60 MW of generating capacity to strengthen the island\u2019s electric\nsystem.<\/p>\n<p>Manager of the NT I Project Implementation Unit, Yogi Yohannes\nSiburian, said that PLTMG Sumbawa II has completed all testing phases\nand is now operating fully with three engines.<\/p>\n<p>PLTMG Sumbawa II uses W\u00e4rtsil\u00e4 dual-fuel engine technology, type\n20V31DF, produced by the Finnish company W\u00e4rtsil\u00e4, configured with three\nengines totalling 30 megawatts.<\/p>\n<p>The technology offers high efficiency of up to 50.2 percent in gas\nmode and 47.9 percent in low-fuel-oil (LFO) mode. In addition, the plant\ncan reach full load in around five minutes.<\/p>\n<p>Yogi explained that the project marked several important milestones,\nfrom initial firing on 19 December 2025, first synchronization on 27\nDecember 2025, to the performance test completed in April 2026.<\/p>",
