The divestment strategy reflects a fundamental shift in how major mining companies approach infrastructure ownership. For decades, miners in northern Chile built their own power and water infrastructure out of necessity rather than strategic choice, responding to inadequate regional energy supply and water availability. The maturation of Chile’s electricity market, particularly the expansion of solar and wind capacity in mining regions, has eliminated the defensive rationale for owning transmission assets. Jorge Cantallops, executive director of mining research center Cesco, noted that the industry developed this capacity while openly stating it was not their core business, but system inadequacy left no alternative.
Juan Carlos Guajardo, executive director of Plusmining, identified the broader trend toward exclusive focus on mineral extraction and processing as driven by capital market demands. Institutional investors purchasing exposure to BHP or comparable miners seek returns tied to copper, lithium, and molybdenum production, not electricity transmission. Maintaining non-mining assets creates a valuation discount as investors cannot cleanly separate core mining cash flows from subsidiary operations. BHP has already sold a 49% stake in power transmission assets serving its Western Australian iron ore operations and continues advancing large-scale copper projects including the Escondida expansion and Argentina’s Vicuña copper district. The Chilean asset sale extends this capital reallocation framework while potentially establishing a precedent for similar transactions by Anglo American, Codelco, and other operators holding legacy infrastructure.
