South Korea Faces Peak Electricity Demand Amidst Heatwave

South Korea is anticipating its highest electricity demand of the summer next week as extreme heat and tropical nights persist following the end of the industry's summer break. The nation's power grid is preparing for a significant surge in consumption.

On August 6th, the maximum electricity demand recorded was 95.561 GW, with a power reserve margin of 10%. This level is generally considered stable, indicating sufficient supply to meet current demand. However, power authorities are closely monitoring the situation.

With the return of industrial operations after the holidays, electricity consumption is expected to climb further. If the current heatwave continues, the maximum electricity demand could reach 94.1 GW under normal conditions. However, a prolonged period of intense heat and tropical nights could push demand as high as 98.8 GW.

This projected peak demand of 98.8 GW would surpass the all-time record of 97.1 GW set on August 20, 2024. The government has stated that it has secured a maximum power supply capacity of up to 107 GW for this summer. In response to the ongoing heat, the Ministry of Trade, Industry and Energy held a meeting to review the power supply status and emergency response systems.

We will once again check whether the response procedures for situations such as sudden demand surges and generator failures are operating without a hitch at the field level.
