September copper and aluminium benchmarks rise, keeping grid-material costs in focus
The October release shows modest monthly rises in both conductor metals; equipment budgets still require contract-specific cost analysis.

Released benchmark data
The World Bank released its October Pink Sheet on 2 October 2026. August → September monthly averages, in US dollars: copper 14,326 → 14,474 per metric tonne; aluminium 3,251 → 3,283 per metric tonne. These are monthly market benchmarks, not October averages or delivered equipment quotations.

How costs reach the project
Editorial analysis: a conductor-metal rise can affect transformer windings, cables and busbars, but the effect depends on metal mass and the pricing formula. Fabrication, insulation, labour and testing remain separate costs. A benchmark movement therefore cannot be applied to the entire equipment purchase price.
Procurement implications
For an August quotation reviewed in October, identify the metal reference month, currency and escalation clause. Compare copper and aluminium designs only after checking losses, dimensions and terminal requirements. This is a procurement interpretation, not a forecast that supplier prices will move by the same percentage.
