South Korea- power blackouts after nuclear plant closures – Increase in thermal underwear sales!
“..A further 3,000 MW is targeted from power savings including less heating at firms and public places, switching off neon lights and even a campaign to wear thermal underwear…”
16 November 2012
South Korean Economy ministry sources said the country may have to bring in rolling power blackouts this winter after the closure of two nuclear plants for safety checks means the electricity network will have under a third of normal reserve capacity.
Asia’s fourth-largest economy said it plans to add 4,000 megawatts (MW) of power supply capacity through savings and new plants in a bid to head off potential blackouts.
The nuclear problems have increased the risk of power shortages in the harsh Korean winter after the closure of the two reactors to replace parts with fake certificates and an extended shutdown of another reactor where microscopic cracks were found.
The northeast Asian country is heavily dependent on oil, gas and coal imports, but usually supplies about a third of its electricity from nuclear power generation from its 23 reactors.
Economy minister Hong Suk-woo said it remained uncertain whether reactors would be restarted in December after parts were replaced because the approval of the regulator was necessary, as well as support from residents.
“This winter will be very, very difficult for us to cope with,” he said, when asked what would happens if reactors did not restart as planned in December
Under the government’s plans, an additional 1,270 MW of power capacity would come from private and public power generators, a statement from the economy ministry said. A further 3,000 MW is targeted from power savings including less heating at firms and public places, switching off neon lights and even a campaign to wear thermal underwear.
Without this, South Korea’s excess generating capacity in January is forecast at 1,270 MW, or 28 percent of the margin that the government aims for to guarantee supplies, the statement said.
With little spare capacity, the grid would be vulnerable to power outages. If two 1,000-MW nuclear reactors fail to restart by the end December, the margin will drop sharply. South Korea would have to conduct rolling blackouts in the public sector if excess power generating capacity falls below 2,000 MW, the ministry said.
If the margin goes down below 1,000 MW, nationwide rolling blackouts could occur, a ministry source said, similar to what happened in September of last year when there was maintenance during a period when demand unexpectedly spiked due to hot weather.
The economy ministry said that shortage of power supply was expected to improve from 2014 as a combined 7,000 MW from power plants would be added to a total of more than 80,000 MW of power generating capacity by the end of 2013.
Minister Hong said South Korea may need to buy more fuel on spot markets to provide extra power, with more LNG imports most likely. The country is the world’s second-largest LNG importer after Japan and its stocks stand at more than 80 percent of storage capacity.
