Indonesia targets 42.6 GW of renewables as Hormuz closure reshapes Asia's energy calculus

Indonesia targets 42.6 GW of renewables as Hormuz closure reshapes Asia's energy calculus PLN's decade-long RUPTL plan hands 73 percent of new capacity to private developers, arriving as the Iran-driven supply shock drives the region back toward coal. Indonesia's state power company PLN published its 2025-2034 electricity supply plan on Monday (2026-06-01), targeting 42.6 gigawatts of new renewable capacity and 10.3 gigawatts of energy storage over the coming decade. The plan, dubbed "Beyond the Greenest," reserves 73 percent of that build-out for independent power producers, shifting the financing burden decisively away from the state utility.⁶ The context could hardly be more difficult. Southeast Asia's electricity consumption surged 24 percent between 2021 and 2025, the Jakarta Post reported, but 70 to 80 percent of that incremental demand was met by coal and gas — a ratio that has worsened since Iran shut the Strait of Hormuz and triggered a regional energy shock.⁶ That shock has extracted a steep toll on global supply. ADNOC chief executive Sultan Ahmed Al Jaber said on Wednesday (2026-05-20) that more than one billion barrels of oil have been lost since the strait's closure, with approximately 100 million additional barrels forfeited every week Hormuz stays shut.² The UAE is constructing a second bypass pipeline, but Al Jaber said the structure is only around 50 percent complete. An existing crude line to Fujairah can redirect some Abu Dhabi exports but carries a maximum capacity of 1.8 million barrels per day, well below normal Hormuz throughput. Even if a ceasefire came immediately, ramping oil flows back to 80 percent of pre-closure levels would take at least four months, Al Jaber said.² Tehran is showing no sign of moving toward a deal. A Poten & Partners executive told Montel on Thursday (2026-05-21) that Iran has little real incentive to reopen the strait, given that its grip on Hormuz remains one of its few concrete sources of leverage in the standoff with Washington.¹ The near-term response across Asia has been to burn more coal. Asian governments are rapidly increasing coal consumption to counter soaring energy prices and supply shortfalls stemming from the conflict, thefutureasia.com reported on Wednesday (2026-05-20). Analysts warned the pivot carries lasting consequences. Dinita Setyawati, senior energy analyst, told the outlet that the shift will impose substantial environmental and public health costs on the region.³ PLN's plan sits against that backdrop as both an ambition and a hedge. By directing 73 percent of planned capacity to private developers, Jakarta is acknowledging that the utility's own balance sheet cannot fund a buildout of this scale. The 10.3 gigawatts of storage embedded in the plan would reduce Indonesia's exposure to gas-price volatility — exactly the kind of exposure that the Hormuz disruption has made more expensive to carry.⁶ Some analysts see the supply shock as a structural tailwind for domestically generated renewables. The crisis could ultimately accelerate the region's shift toward renewable energy, thefutureasia.com reported, as assets insulated from Hormuz risk become relatively more attractive to capital.³ Geopolitics elsewhere in the region complicate the gas supply picture. The Iran shock has revived discussions around the long-stalled Power of Siberia 2 pipeline, with Russian President Vladimir Putin in Beijing on Wednesday (2026-05-20) to meet Xi Jinping, RFE/RL reported. China reportedly wants pricing of around $120-130 per 1,000 cubic meters — matching Russian domestic rates — while Moscow is seeking terms closer to the existing Power of Siberia 1 contract. A deal would divert Russian gas volumes toward China and away from the LNG market, potentially altering spot availability for Southeast Asian buyers.^4,5 The critical test for PLN's RUPTL is whether the 73 percent IPP target generates signed capacity contracts at the scale required or remains a planning aspiration. Indonesia's renewable buildout depends on private capital arriving at the terms the plan assumes — and private capital is now pricing an extended Hormuz disruption, elevated commodity risk, and an Asian region that is, for the moment, still leaning on coal.⁶
