Compania Minera Teck signed AES Corp. for 100% renewable power for the Carmen de Andacollo (CdA) copper mine in Chile. The Chilean branch AES Gener will supply 72 megawatts (MW) of wind, solar and hydroelectric energy from September 1, 2020, through the end of 2031.

Teck said the move furthers the company’s goal to become carbon neutral. “This agreement takes Teck a step closer to achieving our sustainability goals, while also ensuring a reliable, long-term clean power supply for CdA at a reduced cost to Teck,” Teck Chief Executive Don Lindsay said.

AES Gener said the development helps Chile build a more sustainable and reliable grid. The mine is located in the Coquimbo Region. Teck owns a 90% interest in the mine.
