Jeju has recorded its highest power demand ever due to the ongoing heatwave. However, the supply reserve remains sufficient, ensuring stable power supply.
According to the Jeju branch of the Power Exchange, the maximum power demand in the region reached 1186.3 MW as of 7 p.m. on August 4. This figure surpasses the previous summer peak of 1178.6 MW recorded on August 5, 2024.
On that day, the highest temperature in Jeju City rose to 32.4°C, significantly increasing the use of cooling devices. The temperature remained at 28.9°C even at 7 p.m., contributing to the rise in power demand.
The Power Exchange anticipates that if the heatwave and tropical nights continue during the vacation season, maximum power demand could reach new highs.
Despite the surge in maximum power demand, the supply reserve stood at 433.6 MW, with a reserve rate of 36.6%, indicating that the power supply remained stable.
The Jeju branch of the Power Exchange stated that it will take comprehensive measures to manage power supply during the summer supply period, from June 29 to September 18, in preparation for extreme heat, the Jeju-mainland interconnection line, and unexpected generator outages.
