Companies ordered to save power
The Korea Power Exchange (KPX) said it issued a demand response order to companies shortly after the country’s power use soared to 85 million kilowatts at around 9 a.m.
About 2,300 companies complied with the government’s request and saved about 3.3 million kW in electricity use after 9 a.m., sharply up from Thursday’s 1.5 million kW, the exchange said.
The order, this winter’s second, came as most parts of South Korea were hit by a severe cold wave. The temperature in Seoul dipped to minus 15 degrees Celsius (5 degrees Fahrenheit) and a heavy snow warning was issued for the southern island of Jeju, according to the weather agency.
Electricity consumption stood at 83.6 million kW as of 3:15 p.m., with the electricity reserve rate at a stable level of 17 percent, the KPX noted.
The demand response system operates when load reductions are needed to prevent shortfalls in power supply.
Adopted in 2014, 3,580 companies are members of the system. The KPX used the system five times last year.
The severe weather conditions also pushed natural gas usage to 20,599 tons Thursday, marking a record high daily figure, the state-run Korea Gas Corp. said. The total surpassed the previous high of 199,463 tons, which was recorded Dec. 12.
