Indonesia's Singapore Power Export Hits Pricing Stalemate

Deal Momentum Without Deal Terms

Indonesia's state asset fund Danantara signed memorandums of understanding with Keppel Electric, Sembcorp Industries, and Singapore Energy Interconnections in late July for a cross-border renewable electricity venture. The agreements advance a multi-year effort to channel Indonesian clean power south to Singapore, a market hungry for decarbonization but short on land for large-scale solar and wind farms.

Yet the ink had barely dried when Energy and Mineral Resources Minister Bahlil Lahadalia acknowledged that Jakarta and Singapore have not settled the most critical variable: price. Without a tariff framework, the MoUs remain statements of intent rather than blueprints for commercial operation.

Why Price Talks Are Stuck

Singapore's electricity spot market trades at roughly 13 to 18 Singapore cents per kilowatt-hour, shaped by natural gas imports and the city-state's constrained geography. Indonesia, meanwhile, contends with domestic electricity subsidies that hold retail tariffs well below generation cost in many regions. State utility PLN has historically paid renewable developers between 5 and 8 US cents per kWh for solar and wind under feed-in arrangements, though export-grade projects with submarine-cable infrastructure will demand higher returns.

The gap between what Singapore buyers are willing to pay and what Indonesian developers need to justify the capital outlay - undersea high-voltage DC cables can exceed one billion US dollars per gigawatt of capacity - has proven stubborn. Jakarta also faces political sensitivity around exporting power while parts of Java, Sumatra, and eastern Indonesia still experience rolling blackouts during peak demand.

The Broader Energy Corridor Context

Southeast Asia has discussed power pooling for two decades under the ASEAN Power Grid initiative, yet only Laos and Thailand operate a sustained cross-border electricity trade at scale. Indonesia's geography - thousands of islands, uneven grid quality - complicates integration. A renewable export link to Singapore, if realized, would set a template for future sales to Malaysia and potentially beyond.

Danantara's involvement signals Jakarta's intent to treat the project as a strategic investment rather than a purely commercial PLN transaction. The fund, established to consolidate state enterprise stakes, has a mandate to unlock returns from underutilized assets, and Indonesia's renewable resource base - geothermal, hydro, solar across Kalimantan and Sumatra - fits that profile.

What Needs to Happen Next

Negotiators must reconcile tariff expectations with cable economics and domestic political optics. One model under informal discussion is a long-term power purchase agreement in which Singapore off-takers commit to a floor price indexed to their renewable energy certificate market, giving Indonesian developers revenue certainty. Another involves a joint venture structure in which Singaporean capital finances the transmission link in exchange for a share of generation revenue.

Timing matters. Singapore has set a target to import up to four gigawatts of low-carbon electricity by 2035, part of its pledge to reach net-zero by 2050. If Indonesia cannot finalize pricing terms within the next twelve to eighteen months, developers may shift attention to solar imports from Australia via the Australia-Asia PowerLink, a 4,200-kilometer subsea cable project that has already secured environmental approvals and is moving toward financial close.

Indonesia's renewable export ambitions hinge less on resource availability - the country has ample sun, wind, and geothermal heat - and more on whether Jakarta can construct a tariff regime that satisfies foreign buyers, domestic politics, and project finance simultaneously. The MoUs with Keppel, Sembcorp, and Singapore Energy Interconnections prove appetite exists. The hard work of pricing that appetite has only just begun.
