The Korea Power Exchange announced on the 22nd that due to the recent cold wave of around -20 degrees Celsius, electricity demand on the 21st recorded 91,556 megawatts (MW), the highest this winter.
This is believed to be because heating load increased due to the cold wave and solar power generation decreased due to heavy snowfall in the west coast region. Accordingly, electricity demand on the 21st surged by more than 13 gigawatts (GW) compared to last week’s highest demand of 78,513 MW.
Although power demand suddenly increased, power reserve ratio remained stable.
When the government and Korea Power Exchange established winter supply and demand measures, they predicted that electricity demand would rise to 92.6GW in the third week of this month in the event of a cold wave and heavy snow on the West Coast, and secured a supply capacity of more than 105GW.
This week, Hanbit Unit 5 completed maintenance and restarted, and the reduction of electricity demand using demand response resources (DR) also contributed to supply and demand management.
The maximum power demand in winter over the past three years was 95,64MW in 2020, 97,08MW in 2021, and 94,509MW in 2022.
Jeong Dong-hee, chairman of the Korea Power Exchange, said, “If extreme cold waves and heavy snowfall occur in January, additional demand may increase,” and added, “We will actively monitor weather forecasts and re-forecast demand on a weekly basis.”
