Australian mining group BHP has launched a tender for the purchase of 6 terawatts per year of renewable energy sources to supply electric power to its operations in Chile.

“Taking advantage of the unique conditions that Chile offers in terms of renewable resources, BHP aspires, among others, to accelerate its transition toward this type of power generation, in line with its global sustainability goals,” the company said in a statement.

The company wants to hire the 6 terawatt hours in two blocks: one in July 2021 and the second, in January 2022. More details about the bidding process were not provided.

BHP operates the La Escondida copper mine in Chile, which is located in the Atacama Desert, in the northern region of Antofagasta. It is the largest copper reserve in the world.
