On September 26, 2026, KallaGroup announced it is modifying production schedules at its nickel processing facility in South Sulawesi, Indonesia. The operational adjustment follows a noticeable decline in local river discharge driven by ongoing El Niño weather patterns, which directly limits the plant’s ability to generate consistent hydropower.
Because the smelter relies on steady water flow to run its furnaces and metallurgical lines, the hydrological shortfall necessitates temporary output reductions. Company officials noted that the curtailment is a direct response to natural resource constraints rather than equipment downtime or shifting market orders.
The incident underscores the increasing vulnerability of Indonesia’s nickel sector to climate variability, particularly for facilities that depend on renewable hydropower instead of grid or fossil-fuel backups. Prolonged hydrological deficits could constrain regional smelting throughput, potentially tightening short-term refined nickel supplies and influencing Southeast Asian metal pricing benchmarks.
