Heat wave puts S. Korea close to energy crisis
Print Edition
South Korea ordered sweltering government offices to turn off their air conditioners as two power plants stopped operations yesterday, a day after a minister warned of an imminent national energy crisis.
The timing could hardly be worse with South Korea in the grip of an extended heat wave and temperatures nudging 34 degrees Celsius. One Seoul city government employee described her office as “one big dim-sum basket.”
The coal-powered Dangjin III plant, with a capacity of 500 megawatts, was taken offline yesterday due to mechanical issues and will likely remain shut for a week, a spokesman for the state power distributor Korea Power Exchange (KPE) said.
Technical problems also shut down the nearby Seocheon plant. Although operations resumed after an hour, the plant, also coal-fired, is only working at half its 200-megawatt capacity, the spokesman said.
The shutdowns come amid a lengthy disruption in South Korea’s nuclear power sector.
“We are facing potentially our worst power crisis,” Trade, Industry and Energy Minister Yoon Sang-Jick said on Sunday.
“We may have to carry out a rolling blackout... if one single power plant goes out of operation,” Yoon said, appealing to factories, households and shops to curb consumption over the next three days.
The last time the Seoul government was forced to resort to nationwide load shedding was in September 2011, when unexpectedly high demand pushed power reserves to their lowest level in decades.
The unannounced blackouts hit more than 6 million households and businesses and left 3,000 people trapped in elevators.
The resulting outcry forced the then-energy minister to resign.
The government has estimated a future power outage on a similar scale would result in economic losses of around 11 trillion won (US$10 billion).
National reserves of 4.0 gigawatts are considered the minimum necessary to guarantee a steady power supply.
If they drop below 2.0 gigawatts, it triggers an automatic alert requiring all government offices to turn off air conditioners, lights and any non-essential devices.
In a pre-emptive move yesterday, the energy ministry ordered such measures effective immediately, even though the key reserve mark had not been breached.
Describing the current situation as “extremely urgent,” the ministry also ordered government offices to turn off water coolers and staff to use staircases where possible, rather than elevators.
