Record-Breaking Heatwave Drives Air Conditioner Sales Surge, Power Demand Hits 93.4GW

Unprecedented Summer Heat Challenges Energy Infrastructure and Consumer Markets

South Korea is grappling with an extraordinary early summer heatwave that has driven air conditioner sales to unprecedented levels while pushing electricity consumption to a record-breaking 93.4 gigawatts (GW) on July 7, marking the highest July power demand in the nation's history.

Air Conditioner Sales Boom

Major appliance manufacturers report dramatic increases in air conditioning unit sales during the first half of 2025. Samsung Electronics' residential stand and wall-mounted air conditioner sales have significantly exceeded previous year levels, with July showing particularly explosive growth as the persistent heatwave continues.

LG Electronics and Winia Daewoo report similar trends, suggesting this year's air conditioning market will substantially outperform typical seasonal patterns. Industry representatives note that consumer demand has shifted 2-3 weeks earlier than normal due to June's early onset of extreme temperatures.

An industry spokesperson explained, 'The early heatwave beginning in June has accelerated air conditioner purchases by 2-3 weeks compared to average years. We're seeing particularly strong demand for high-efficiency inverter models.'

Record-Setting Power Consumption

Korea Electric Power Corporation data reveals July 7's peak electricity demand reached 93.4GW, substantially exceeding previous July consumption records. This unprecedented figure reflects earlier-than-expected extreme heat driving cooling-related power consumption beyond forecasted levels.

The Korea Power Exchange stated, 'Continuous heatwave conditions have caused cooling power demand to surge beyond expectations. We're operating all available generation facilities to ensure stable power supply.'

The trend of increasingly hot summer weather accompanied by rising electricity demand highlights the need for power supply planning reassessment, according to industry experts.

Heatwave Advisory Issued and Lifted

Nationwide heat advisories were lifted at 2 PM on July 13 as meteorological conditions temporarily improved. The Korea Meteorological Administration forecasts rain across southern regions through July 15, providing temporary relief from the extreme temperatures.

However, mid-week projections indicate heat will return with renewed intensity. While a tropical depression passing south of Jeju Island will temporarily moderate temperatures, subsequent weather patterns suggest renewed temperature increases.

Agricultural Product Price Inflation

The extreme heat is significantly impacting agricultural commodity prices. Korea Agro-Fisheries & Food Trade Corporation data shows watermelon retail prices averaged 29,115 won per unit as of July 11, representing a 22.5% increase from the previous week and substantial year-over-year growth.

Cabbage prices have similarly increased more than 20% within a week, adding to household financial burdens during the summer season. Prolonged extreme temperatures are adversely affecting crop growth, intensifying price pressure across agricultural markets.

The Ministry of Agriculture, Food and Rural Affairs responded with Minister Song Mi-ryeong visiting Hongseong County pig farms in South Chungcheong Province on July 13 to personally inspect heatwave response measures.

Seafood Market Price Surge

Marine environments are also feeling temperature rise impacts. Prices for popular fish varieties including flounder and rockfish, considered 'national sashimi fish,' continue climbing daily.

Climate change effects from last year's high water temperatures causing massive fish kills, combined with this year's early extreme heat, are raising concerns about aquaculture supply stability. A Korea Maritime Institute representative stated they are 'closely monitoring water temperature rise impacts on aquaculture industries.'

Zoo Animal Heat Management

Extreme weather affects zoo animals as well. Cheongju Zoo in North Chungcheong Province has implemented special measures during the 14-day consecutive heat advisory period.

The Asiatic black bear 'Ban-i' cools off by soaking in water pools, while zoo management provides half-baths and special fruit treats to reduce animal heat stress.

Heat-Related Illness Surge

Heat advisories beginning in June have contributed to sharply rising heat-related illness cases. Korea Disease Control and Prevention Agency data shows 82 heat-related patients in North Jeolla Province from mid-May through July 10.

Several fatalities have occurred, confirming extreme heat dangers. Health authorities advise avoiding outdoor activities, maintaining adequate hydration, and resting in cool environments as essential heatwave precautions.

Government Response Measures

The government has initiated comprehensive pan-governmental measures addressing record-breaking heat conditions. Particular focus centers on protecting vulnerable populations and ensuring power supply stability through multi-faceted approaches.

The Ministry of the Interior and Safety operates heatwave response situation rooms while collaborating with local governments to expand cooling center operations and conduct safety checks for elderly individuals living alone and other vulnerable groups.
