The smelter runs dry: 570 workers furloughed as drought hits Indonesia's nickel belt

The smelter did not run out of nickel. It ran out of water. PT Bumi Mineral Sulawesi is furloughing 570 workers at its Bua complex in Luwu, South Sulawesi — most from Plant 1’s ferronickel smelter, some from Plant 2 — not because demand collapsed or prices crashed, but because an El Niño drought has starved the hydroelectric plant that powers the furnaces. The RKEF Line 1 — the rotary kiln-electric furnace line that turns nickel ore into ferronickel — is running reduced. The energy ministry is monitoring. The furloughs are described as voluntary. The workers keep their health, employment, and pension insurance, plus Rp1.5 million a month — about US$84 — and remain employees. The water will return. The question is what the drought revealed while it was gone.

Plant 1 produces 33,000 tonnes of ferronickel a year — RKEF technology, part of the Kalla Group, operated by its Bukit Harapan subsidiary — and its idling is a parable of Indonesia’s nickel miracle: the world’s largest producer, the downstreaming champion, the EV battery hope, brought low not by markets but by rain. The industry’s squeeze is real — weak nickel prices, high energy costs, Jakarta’s production quota cuts (Weda Bay’s quota slashed from 42 million to 12 million tonnes for 2026), rare-earth content checks delaying exports — but BMS’s furloughs are the water story, and the water story is the climate story. Even IMIP, the giant of Morowali, faces the same constraint. When the rivers run low, the furnaces go quiet.

The drought beneath the boom

El Niño is the Pacific’s old cycle — the warming of the eastern ocean that dries Southeast Asia — but its industrial consequences are new. Indonesia’s nickel downstreaming was built on a bet: that the archipelago’s rivers could power the smelters that process its ore. The RKEF process is electricity-hungry — the furnaces run at 1,600 degrees, day and night, the power demand of a small city per plant. Hydroelectricity was the answer: cheap, renewable, domestic. The drought is the answer’s limit. When El Niño parks over the Pacific, Sulawesi’s rivers shrink, the turbines slow, and the smelters — the pride of the downstreaming policy — throttle back.

The 570 workers are the human face of the hydrological cycle. Furloughed, not fired — the distinction matters in Indonesia’s labor law and in the workers’ lives. They keep their insurance, their pension contributions, their employment status, and Rp1.5 million monthly — US$84, a fraction of a smelter wage, enough to subsist in Luwu, not enough to plan on. “Voluntary” is the ministry’s word; the workers’ word is unrecorded. The furlough is indefinite — tied to the water, and the water to the sky. In the nickel belt, the weather is now an industrial input, and the input has failed.

The energy ministry’s monitoring is the state’s acknowledgment that this is systemic, not singular. IMIP — the Indonesia Morowali Industrial Park, the Tsingshan-built giant that anchors the global nickel trade — faces the same water constraint, and IMIP’s scale makes BMS’s 570 furloughs look like a warning shot. If the drought persists, the question moves from one plant’s workers to the industry’s output — and from the industry’s output to the global nickel price, the EV battery supply chain, the energy transition’s most exposed metal.

The nickel squeeze

The water crisis arrives inside a broader squeeze, and the squeeze deserves its full telling. Nickel prices are weak — the boom of 2022, when the metal spiked on shortage fears, has given way to the glut of Indonesian supply itself. Indonesia’s downstreaming success — the export ban of 2020, the smelters that rose in Morowali and Weda Bay — flooded the market with the very metal it was meant to valorize. The country won the volume war and lost the price war: more nickel, worth less, the classic commodity trap.

Jakarta’s response has been quotas — the production limits meant to support prices by constraining supply. Weda Bay’s quota cut from 42 million to 12 million tonnes for 2026 is the sharpest signal: the state throttling its own champion to save the market. But quotas are a blunt instrument in a fragmented industry — the big parks negotiate, the small smelters evade, the ore flows through channels the ministry cannot see. And the rare-earth content checks — the new export inspections delaying shipments — add friction to a trade that runs on velocity. Every delay is a cost; every cost lands on the smelters already squeezed by energy prices.

Energy is the squeeze’s other jaw. The smelters run on power — hydro when the rivers flow, coal when they don’t — and Indonesia’s electricity economics are unforgiving. Coal is cheap but carbon-heavy, a liability as the EU’s carbon border tax approaches. Hydro is clean but drought-vulnerable, as BMS has learned. The industry’s bet — that Indonesian nickel would be both cheap and green — assumed the rivers would cooperate. El Niño has called the assumption.

The downstreaming gamble

To understand the stakes, rewind to the gamble. In 2020, President Joko Widodo banned nickel ore exports — the raw rock that Indonesia had shipped to China for decades — forcing the value chain onshore. The smelters rose in Morowali and Weda Bay, Chinese capital and Indonesian ore fusing into the world’s nickel workshop. The policy was the developing world’s most ambitious industrial bet: not just exporting commodities but capturing the manufacturing margin, the jobs, the technology. It worked — Indonesia now dominates global nickel supply, the EV battery chain runs through Sulawesi, the GDP numbers glow.

But the gamble’s fine print is being read now. Downstreaming concentrated risk: the industry’s geography — Sulawesi’s coasts, the river valleys — concentrated the water risk. The Chinese capital that built the smelters concentrated the geopolitical risk — Washington’s IRA subsidies exclude Indonesian nickel, the “foreign entity of concern” rules treating the Tsingshan-built parks as Chinese. The price collapse concentrated the economic risk — the more Indonesia produces, the less it earns. And the drought concentrates the climate risk — the rivers that power the furnaces are the weather’s hostage.

The Kalla Group’s presence — Jusuf Kalla’s conglomerate, the former vice president’s empire — is the domestic political economy made visible. Indonesian industry runs on conglomerates with political roots; the smelters are not just factories but networks of obligation. BMS’s furloughs will be managed through those networks — the ministry monitoring, the insurances maintained, the Rp1.5 million paid — because the political cost of 570 angry workers in Luwu exceeds the economic cost of carrying them. The furlough is industrial policy by other means: the state and the conglomerate sharing the drought’s burden, the workers carried until the water returns.

The battery connection

The reason the world should care about 570 furloughed workers in Luwu is the battery in the electric car — or rather, the chemistry inside it. Nickel is the energy-density metal: in the NMC (nickel-manganese-cobalt) cathodes that power most long-range EVs, nickel is what stores the charge. More nickel, more range; the industry’s push toward high-nickel chemistries (the “811” batteries — 80% nickel) made Indonesia’s ore the most strategic rock in the energy transition. Every EV sold in Europe or America contains, in all likelihood, Sulawesi nickel — mined, smelted, and shipped through the supply chain that BMS’s drought has just interrupted.

The geopolitics of that chain are the decade’s industrial drama. Washington’s Inflation Reduction Act — the subsidies meant to onshore the EV supply chain — excludes minerals from “foreign entities of concern,” a category that captures much of Indonesia’s Chinese-built nickel industry. The result is a bifurcated market: “clean” nickel for the American supply chain (Canadian, Australian, at a premium) and Indonesian nickel for everyone else (Chinese, at a discount). BMS’s ferronickel — destined for stainless steel more than batteries, but part of the same industrial ecosystem — sits in the second stream. The drought thus hits the China-facing supply chain hardest — which is to say, it hits the supply chain that actually produces most of the world’s batteries.

The price paradox deserves its full weight. Nickel is weak — the glut — yet the energy transition needs more of it every year. The market is telling producers to stop (low prices) while the climate is telling them to expand (rising demand). This is the commodity cycle’s cruelest phase: the investment strike, when low prices kill the new mines and smelters that the future needs, guaranteeing the next shortage. BMS’s furloughs are a microcosm: a smelter idled by drought in a market signaling oversupply, while the EV factories — the demand of 2030 — are being built on the assumption the nickel will be there. It will be, until it isn’t.

The green paradox

There is an environmental ledger that the nickel boom keeps off the books, and the drought puts it on. The smelters’ footprint in Sulawesi is vast: the forests cleared for the industrial parks, the rivers dammed for the hydro plants, the tailings — the toxic slurry left after the nickel is extracted — disposed in ways that have drawn sustained criticism. Deep-sea tailings disposal, practiced at some Indonesian operations, is banned in most of the world; in Sulawesi, it is business. The coral reefs off the nickel coasts — among the most biodiverse marine ecosystems on earth — absorb the industry’s externalities.

The paradox is sharp: the metal of the clean transition is produced dirtily. Indonesian nickel’s carbon footprint — coal-powered smelting, deforestation, the whole chain — is among the highest in the industry, which is why the EU’s carbon border adjustment mechanism looms over it like a coming tax. The “green nickel” premium — the higher price for verifiably clean production — is the market’s attempt to square the circle, but the circle resists: the nickel the transition needs most urgently is the nickel produced most carbon-intensively. BMS’s hydro-powered smelter was supposed to be the answer — clean power, green nickel. The drought’s answer: the clean power is the vulnerable power.

The indigenous dimension is the ledger’s most sensitive entry. Sulawesi’s nickel belt overlaps the lands of communities — the Karonsi’e Dongi, among others — whose forests became smelters with compensation the communities describe as inadequate and consultation they describe as absent. The furloughs’ 570 workers include the sons and daughters of those communities — employed by the industry that displaced them, now idled by the drought that the industry’s dams were meant to master. The circle is complete, and it is not virtuous.

What the world sees

Western coverage — mining trade press, the EV supply-chain analysts — reads BMS as a data point in the nickel glut: another smelter throttling, another signal that Indonesian supply is not the infinite tap the market assumed. The frame is commercial: what does 33,000 tonnes of ferronickel offline do to prices? (Little, in a glut — which is the problem.) The deeper Western read is about the energy transition’s fragility: the batteries that will decarbonize transport depend on a metal whose production depends on rivers whose flow depends on a Pacific cycle. The green transition has a water footprint, and the footprint is showing.

China’s lens is the supply-chain one — and the most exposed. Chinese stainless steel and battery makers depend on Indonesian nickel; Tsingshan’s Morowali empire is the physical plant of that dependence. A drought that idles BMS threatens, at scale, the input to China’s EV dominance — the CATLs and BYDs whose batteries need Indonesian nickel. Beijing’s read is operational: diversify supply, secure the quotas, manage the water. The drought is a reminder that the supply chain’s chokepoint is not just geopolitical — it is hydrological.

The Southern lens — Jakarta, Manila, the resource-nationalist press — reads the furloughs as the downstreaming debate’s latest round. The policy’s defenders: 570 furloughed is better than the thousands who would never have been hired without the smelters; the drought is weather, not policy failure. The critics: the smelters employ few relative to their footprint; the value captured is Chinese; the environmental cost — the rivers dammed, the forests cleared, the tailings — is Indonesian. The furloughs are ammunition for both sides: proof the industry is fragile, proof the safety net works. The debate will outlast the drought.

The water economy

Step back, and BMS is a case study in the water economy — the emerging discipline of industries built on rivers that no longer run reliably. The nickel smelters are the most dramatic example, but the pattern repeats: the hydropower dams of Laos, the semiconductor fabs of Taiwan (TSMC’s drought vulnerability is the industry’s open secret), the agriculture of the Mekong. El Niño is cyclical; the warming that intensifies it is structural. Each cycle will test the industries built for the old hydrology.

Indonesia’s answer — the ministry monitoring, the quotas, the content checks — is the resource state learning to manage scarcity instead of abundance. The downstreaming era assumed infinite ore, infinite water, infinite demand. The furloughs announce the finite: finite rivers, finite prices, finite patience. The policy’s next phase — if there is one — must price the water, not just the nickel. The smelters were built for the ore. They must now be rebuilt — in planning, in power sourcing, in labor policy — for the drought.

The 570 workers of Bua are the transition’s human ledger. They keep their insurance, their status, their Rp1.5 million — the system carrying them, as systems should. But they also keep the knowledge that their livelihood depends on rain — the oldest vulnerability, in the newest industry, in the country that bet its future on the furnaces. The water will return; El Niño always passes. The question is whether the industry that waits for it will be the same one that was furloughed — or whether the drought, like all droughts, will reveal which parts were built on rock and which on the river’s promise.

What to watch

Watch the rivers: Sulawesi’s water levels are the industry’s leading indicator, and the El Niño forecast is the furloughs’ timetable. Watch IMIP — if the giant throttles, the 570 becomes 5,700, and the nickel price moves. Watch Jakarta’s quota politics: the Weda Bay cut is the template, and every smelter is gaming the next round.

And watch the workers. The furlough is “voluntary,” the compensation is Rp1.5 million, the insurances are maintained — the system’s promise. The promise holds until the drought outlasts the patience, until the “voluntary” becomes the permanent, until the river’s failure becomes the industry’s. In Luwu, 570 families are waiting for rain. The nickel market, the EV transition, the downstreaming gamble — all of it, in the end, comes down to water. It always did.

Watch the carbon border, too. The EU’s mechanism will eventually price the carbon in every tonne of Indonesian ferronickel — and the hydro-powered smelters, drought and all, are the industry’s best defense. BMS’s idle furnaces are a preview of the adaptation the whole sector faces: power systems diversified beyond the river’s mercy, labor systems built for the pause, an industry engineered for the climate it has, not the climate it assumed. The water will return. The lesson had better outlast it.

Western coverage — mining trade press, commodity analysts — treats the furlough as a supply data point with a human face. The frame is market-mechanical: 570 workers idled, one RKEF line throttled, another small subtraction from Indonesian ferronickel output in a year of quota cuts and export delays. The West's eye is on the nickel price — whether drought joins quotas and checks as a third bullish force, or whether the market, unimpressed so far, keeps shrugging.

The Western lens also reads the $84-a-month figure as a window onto emerging-market industrial economics. In this telling, the furlough terms are both humane by local standards and a measure of how thin the margin is between a job and its absence in the commodity cycle.

Eastern coverage — Chinese industry commentary — reads the furlough through the supply chain it feeds. The narrative: Chinese stainless and battery producers depend on Indonesian nickel units, and every idled furnace in Sulawesi is a cost passed up the chain to the world's workshops. In this telling, the drought is doing what Jakarta's quotas were designed to do — tightening supply — only faster and without a policy lever to reverse it.

The Eastern lens dwells on the fragility with a strategist's eye. An industrial policy built on hydropower in an El Niño zone, in this reading, has a single point of failure the planners missed. Chinese capital built these smelters; Chinese analysts are now pricing the climate risk the feasibility studies underweighted.

The Global South lens — Indonesian, African and Latin American press — reads this story in the faces of the 570. For the South, a furlough is never just a supply data point; it is 570 households in Luwu living on $84 a month while the company waits for rain. The coverage centres the workers' terms — kept on the books, coverage maintained, a retainer rather than a severance — and asks the harder question: who bears the climate risk in the green-transition supply chain?

What stings, in the South's telling, is the asymmetry of the boom. The nickel in Sulawesi's furnaces becomes the stainless steel and EV batteries of the energy transition — the transition the North celebrates — while the workers who make it possible absorb the drought first. The South's lesson: the green economy has weather, too, and it is the poor who feel it.
