Nickel downstreaming keeps value at home but raises the governance bar

What downstreaming has delivered, in hard numbers

Since Indonesia permanently banned raw nickel ore exports in January 2020, the headline economic case for processing nickel at home rather than shipping it out as ore has largely held up in the data. The value added from Indonesia's nickel production grew from roughly US$1.4 billion in 2020 to US$34.8 billion in 2023, according to analysis from the Center for Strategic and International Studies (CSIS), an eightfold increase inside three years. On the fiscal side, Septian Hario Seto, Deputy for Investment and Mining Coordination at the Coordinating Ministry for Maritime Affairs and Investment, reported that tax revenue collected from companies under the nickel downstream tax holiday reached Rp17.96 trillion in 2022, up from Rp3.99 trillion in 2019 and just Rp1.66 trillion in 2016, an increase of nearly eleven times in six years. Corporate income tax from the same group of companies rose even faster, from Rp0.34 trillion to Rp7.36 trillion over the same period, a 21.6-fold increase.

Those figures explain why downstreaming remains one of the most defended pillars of Indonesian industrial policy regardless of which administration is in office. They also explain why the debate has moved from whether processing nickel at home creates more value than exporting ore, which is now well established, to the harder question of how much of that value actually stays in Indonesia, and what it costs to produce.

The smelter build-out, project by project

The scale of construction behind those numbers is considerable. A late-2025 dataset from the Center for Global Sustainability at the University of Maryland tracked 106 nickel smelter projects across Indonesia, of which 59, or 55.7 percent, were confirmed operating. The rest of the picture is less tidy than headline investment figures suggest: 21 projects had stalled with no visible progress for at least three years, and five smelters that had previously operated were shut down, largely due to the high cost of imported coking coal and weak global nickel prices. Geographically, the build-out is heavily concentrated in three provinces: Central Sulawesi hosts 35 smelter projects, North Maluku 32, and Southeast Sulawesi 20, of which 11 in the latter province carry stalled status.

That concentration is a known feature of the policy, not an accident. Indonesia's two largest processing hubs, the Morowali Industrial Park (IMIP) in Central Sulawesi and the Weda Bay Industrial Park in North Maluku, account for a large share of national smelting capacity between them. Entering 2026, the Ministry of Energy and Mineral Resources (ESDM) has also trimmed the annual nickel ore production quota (RKAB) to a range of 260 to 270 million tonnes, down from earlier plans, as regulators try to balance ore supply for existing smelters against a persistent global nickel oversupply and a moratorium on new intermediate smelter licenses. Managing that balance, enough ore to keep 59 operating smelters running without flooding an already soft market, has become as much a governance task for ESDM as an industrial one.

A number that outlasted its own controversy

The precise scale of downstreaming's benefit to Indonesia has itself been publicly contested, in a debate that is worth citing here because it illustrates exactly the kind of measurement gap Sirkularium works to close. In 2023, President Joko Widodo stated that raw nickel ore exports had generated only around Rp17 trillion a year for the state, a figure that rose to Rp510 trillion once the same nickel was processed domestically into downstream products before export. Economist Faisal Basri publicly challenged the comparison, arguing that the underlying trade data years and product categories were not directly comparable, and noting separately that around 99 percent of Indonesia's nickel pig iron and ferronickel exports go to China for further processing into stainless steel and battery precursor materials, meaning a meaningful share of the value captured downstream of Indonesia's own smelters accrues to Chinese industry rather than Indonesian industry.

"Nilai tambahnya belum tentu benar-benar mengalir untuk Indonesia," Faisal Basri argued, pointing to how much of Indonesia's processed nickel output is itself an intermediate input for further, higher-value processing done abroad.

Neither side of that exchange disputes that downstreaming has raised Indonesia's nickel export value substantially. What remains genuinely unsettled, and unsettled precisely because Indonesia lacks a single, independently verified, standardized methodology for tracking value capture across the full nickel-to-battery chain, is how that value is distributed between Indonesian producers, foreign investors, and downstream processors overseas. That is a measurement problem before it is a policy problem, and it is the kind of gap that consistent, third-party economic valuation is built to close.

The energy bill behind the boom

The other side of the ledger is energy. Nickel smelting is highly electricity-intensive, and WRI research found that furnace power alone accounts for more than 60 percent of total energy use in nickel processing, of which 97 percent is supplied by captive coal-fired power plants built and operated by the nickel industry itself, outside Indonesia's national grid. In 2023 alone, the nickel industry consumed roughly 100 billion kilowatt-hours of electricity, comparable to powering 10 million American homes for a year, or close to 80 percent of all household electricity consumption in Indonesia. Captive coal-fired generation is now the largest single source of emissions in the nickel sector, accounting for 63 percent of the total.

A January 2026 analysis by the Centre for Research on Energy and Clean Air (CREA) and Global Energy Monitor found that captive coal capacity, most of it tied to nickel and other metals processing in Central Sulawesi and North Maluku, more than doubled in those two provinces since 2023 and could reach 31 gigawatts if every proposed project proceeds, a figure that would exceed Australia's entire current coal fleet. That scale of build-out is precisely the kind of concentrated infrastructure commitment that benefits from being measured and planned with the same rigor applied to the smelters themselves, so that the energy transition Indonesia's nickel is meant to help supply does not quietly rest on an expanding coal base at home.

What credible governance looks like from here

None of this argues against downstreaming as a strategy. It argues for treating the sector's economic, fiscal, and energy accounting with the same seriousness that went into building it. That means standardized, independently verifiable reporting on where nickel's value actually lands along the export chain, transparent tracking of which of the 106 tracked smelter projects are genuinely productive versus stalled or shuttered, and an honest, published accounting of the captive coal capacity each new processing hub requires and how that capacity is expected to be managed as Indonesia's broader power sector decarbonizes. Each of those is a data and methodology exercise more than a policy reversal, and each is achievable with tools already in use elsewhere in Indonesia's resource sector.

Sirkularium's view

Indonesia's nickel downstreaming policy has done what it set out to do on its own terms: value added, tax revenue, and export sophistication have all risen sharply since the 2020 export ban. The unresolved question is not whether the policy works, but whether Indonesia can measure, with the same rigor it applies to production tonnage, exactly how that value is distributed and what it costs in energy and land. The public disagreement between government and independent economists over a single headline number is itself the clearest argument for standardized, independently verified economic valuation of the nickel value chain, from ore to cathode to captive power plant, commissioned as routine practice rather than produced only when a dispute forces the question. That is the kind of accounting that lets government defend the policy's real gains with confidence, and lets operators demonstrate, credibly, exactly how much of the value they create actually stays in Indonesia.
