Chilean power restored partially after massive outage, as copper mines are brought back online

Chile's major copper mines and power grids are coming back online after a major power outage that rocked this world's leading producer of red metal. Power companies are working to restore full system operation, according to authorities.

A transmission line failure in the north of the country caused the power outage that struck Tuesday afternoon, plunging most of the nation into darkness. Major mines were also left without electricity, causing global metal markets to be shook.

The National Electricity Coordinator of Chile (CEN), in its early morning report Wednesday, said that more than 90% of the residential consumption was restored. However, media outlets reported intermittent electricity in some cities.

The National Electricity Coordinator is continuing to work towards achieving 100% recovery of consumption, it says.

Anglo American reported that its Los Bronces, El Soldado and Chagres smelters in central Chile had resumed normal operations as of Wednesday morning. The smelter at Chagres still lacked electricity but used generators to run critical processes.

Codelco - the world's biggest copper producer - reported in its final report, late on Tuesday night, that power outages continued at its various divisions.

The company said that there had been a partial restoration of power in El Teniente, allowing ventilation to be resumed underground. In the smaller Salvador mine, service was restored. Work was underway to restart the concentrator and the smelter.

The status of other mining operations has not yet been updated by the companies. The curfew declared by the government in the regions affected by the outage was lifted at 6 a.m. local (0900 GMT).

Santiago's metro service has announced it will restart most of its stations and lines.
