99.3GW on the 10th, 98.5GW on the 11th… Midsummer level
Authorities: “47.5GW expected during Chuseok holidays… No plans to control output”
As the hot weather continues in September with temperatures exceeding 30 degrees Celsius, electricity demand is reaching midsummer levels.
According to the Korea Power Exchange on the 15th, the maximum total electricity demand on the 11th was recorded at 98.5 GW (gigawatts).
Following 97 GW on the 9th, 99.3 GW on the 10th, and 98.5 GW on the 11th, it is continuing at a level similar to midsummer.
Last year, the total weekday demand in the second week of September was lower than this year, at 89.1 GW on the 11th, 88.6 GW on the 12th, and 84.4 GW on the 13th.
The total electricity demand estimate is the sum of the ‘demand within the electricity market’ of the Korea Power Exchange and ‘demand outside the electricity market’ such as direct purchase agreements (PPA) with KEPCO, most of which are solar power generation, and small-scale private solar power generation.
Because it is difficult to calculate the exact output of private solar power plants traded outside the electricity market, the power exchange is disclosing total demand estimates that take into account forecast errors.
With nearly half of September gone, the night heat has not let up, so electricity demand is expected to remain high for some time.
Tropical nights also occurred in Incheon, Daejeon, Mokpo, Busan, Pohang, and Jeju on the nights of the 14th and 15th. The highest temperature in September continues to set new records.
The previous day, new high temperature records for September were set in Gwangju (34.8 degrees), Tongyeong, Gyeongnam (34.4 degrees), and Gimhae (36.5 degrees). In mid-September, new records were set in more areas, including Daegu (34.9 degrees) and Ulsan (33.3 degrees).
Power authorities are working to ensure a stable supply and demand of electricity, predicting that the late summer heat in September will result in a minimum demand of 47.5 GW during the Chuseok holiday period. This is about 9 GW higher than the minimum demand of 38.4 GW during the Chuseok holiday last year.
In addition, the authorities did not implement output controls for solar power generation during the holiday period. This is because the weather is cloudy and solar power generation is expected to be lower than usual, and there is no need to reduce power generation as demand for cooling such as air conditioning is high due to the late summer heat.
The Korea Power Exchange said, “There are no plans for output control measures as the Chuseok holiday period is expected to continue to be higher than average temperatures and cloudy and overcast.”
