SANTIAGO – A major blackout left most of Chile without power for hours on Sunday, two weeks after a massive earthquake that killed hundreds and weakened infrastructure.
Electricity was restored quickly, but the failure of the South American country’s main power grid was another test for conservative Chilean president Sebastián Piñera, who took office last week and must rebuild after the huge earthquake.
The power cut rattled the nerves of Chileans still living with aftershocks following the deadly 8.8-magnitude quake on February 27th that triggered tsunamis and tore up roads and towns, causing an estimated $20 billion (€14.6 billion) to $30 billion in damage.
The lights went out at 8.50pm local time, affecting millions of people and most of Chile’s main cities in a stretch of territory more than 2,000km (1,200 miles) long from north of the capital, Santiago, to Puerto Montt in the south.
The quake-devastated city of Concepción was among those plunged into darkness and some of the country’s key copper mines briefly halted production.
Soon after midnight, power had returned to about 90 per cent of Chile, a long, narrow country that produces copper, fruit and wine and is one of the most developed in the region.
Claudia Morales (32) was on the Santiago subway when the power cut hit, stranding commuters in the dark for about 15 minutes.
Phones were down too, so they could not call anyone. “Everyone started to say aloud maybe there had been another quake,” she said. “Everyone was really panicked.”
Passengers had to be evacuated from several subway cars.
Chilean interior minister Rodrigo Hinzpeter said the blackout was due to a problem with a 500 kilowatt transformer. “Fortunately the reason for the failure has been identified,” he said.
Mr Hinzpeter said that while the power outage was not directly related to the earthquake last month – which knocked out power at the time – there would be an investigation to see whether there was an indirect cause.
Chilean energy minister Ricardo Rainieri said the quake left the power grid fragile and urged Chileans to limit energy consumption.
State mining giant Codelco, the world’s top copper producer, said the disruption briefly shut its mines in central Chile. Global miner BHP Billiton’s Escondida deposit, the world’s largest copper mine, was operating normally and was not affected.
The central interconnected system, or SIC grid, was the one affected. But most of Chile’s copper mines are on the northern power grid, so they were not affected. – (Reuters)
