Indonesia–Singapore Green Power Trade: Danantara, 3.4 GW, and the Price Standoff

The Prabowo–Wong meeting of July 6, 2026 at Merdeka Palace produced 26 bilateral agreements — spanning trade to cybersecurity. But one item stands as the decade’s wager: cross-border green electricity trade between Indonesia and Singapore, targeting at least 3.4 gigawatts (GW) of low-carbon power flowing to the city-state by 2035.

Two months on, no cable has been laid — pricing talks grind on. That is precisely where the story gets interesting: how two neighbors negotiate the price of a shared future. Below: the status, the hurdle, and the stakes — drawing on Reuters, Singapore’s MTI, Antara, and Danantara’s official release.

What Was Agreed: 26 Deals, Danantara in Front

The July package is layered. At government level (18 of 26 deals), a cross-border electricity trade (CBET) roadmap. At business level (8 deals), Danantara — Indonesia’s sovereign wealth fund — was designated implementation lead through its investment arm: MoUs with Keppel Electric and Sembcorp Utilities on offtake, an MoU with Singapore Energy Interconnections (SGEI, Singapore’s appointed interconnector developer) on commercial-technical groundwork, plus a joint roadmap with Singapore’s MTI.

The scheme is more than electron sales. Three prior-year energy MoUs form the foundation: green power exports, green industrial estates in Indonesia, and carbon capture and storage (CCS) cooperation. Before first flow, both governments must finalize an internationally aligned cross-border Renewable Energy Certificate (REC) framework — the carbon accounting that determines whether this power counts as “green” in global markets.

The Price Hurdle: State-Set Tariffs and a Stubborn Win-Win

The single remaining issue, per Energy Minister Bahlil Lahadalia after the summit: price. Indonesian regulation places electricity tariffs in government hands — so this is economic diplomacy, not corporate haggling. “I think there will be a breakthrough soon. We want everybody to reap the benefits, reaching a win-win solution for both,” Bahlil told Reuters.

Jakarta’s position reads rationally against the data: as of August 2026, Singapore had granted conditional approvals to 13 projects (9.25 GW total) across five countries — Australia, Cambodia, Indonesia, Malaysia, Vietnam — with six Indonesian projects advanced to further licences. Indonesia thus competes with four rivals for Singapore’s 6 GW 2035 import target. Priced too cheap, domestic value-add bleeds away; priced too dear, Singapore turns elsewhere. This is where “win-win” gets tested as arithmetic, not rhetoric.

Indonesia’s Upside: Green Industry, Not Just Electron Sales

Jakarta insists this is not raw-electron export. Investment Minister Rosan Roeslani called it new, additional generation capacity — distinct from domestic supply — catalyzing green industrialization: green estates, higher-value jobs, and Indonesia’s standing as a regional clean-energy heavyweight.

The logic connects to the 100 GWp solar program: new capacity built for export simultaneously deepens the domestic green manufacturing base. “We believe such a project is a win-win for both countries,” said PM Lawrence Wong — and from Jakarta’s side, the “win” is measured in factories and jobs at home, not megawatts across the strait.

ASEAN Grid Test Case: From Decades of Ambition to the First Cable

The largest meaning transcends the bilateral. The ASEAN Power Grid — Southeast Asia’s electricity-interconnection vision — has been a decades-long slow burn; the four-nation LTMS-PIP pilot proved the concept can work. Analysts cited by the South China Morning Post see Indonesia–Singapore cooperation as potentially the first practical test case carrying that vision from documents to cables.

The exam is layered: an agreed price, a recognized cross-border REC regime, and synchronized regulatory frameworks on both sides before decade’s end. Pass all three and this subsea cable becomes precedent that regional decarbonization and high-value growth can coincide. Fail on price and it becomes an expensive lesson in the limits of win-win rhetoric.
