China Heatwave Drives Record Power Demand as El Niño Looms

Northern China is enduring a persistent heatwave with temperatures exceeding 35°C in multiple cities including Beijing and Shijiazhuang, while southern China has set new all-time records for electricity demand as cooling needs surge. The twin crises come as the National Climate Center warns that an El Niño event is expected to intensify through summer and autumn.

Heatwave Grips the North

Beijing and Shijiazhuang both recorded their first heatwave day of 2026 on May 30, with Beijing reaching 35°C at 14:23 and Shijiazhuang at 12:12, according to Beijing News. Localized areas in Beijing recorded temperatures as high as 39.1°C at the Taizimu monitoring station. Shijiazhuang is expected to face three consecutive days of high temperatures from May 30 to June 1, with Xinhua News reporting that northern China will continue to see sunny, hot weather across multiple areas.

Southern Grid Shatters Records

On May 25 at 20:21, the China Southern Power Grid set a new all-time record electricity load of 259 million kilowatts, surpassing the previous peak by 1.83 million kilowatts — a 0.71% increase. The China Southern Power Grid reported that this year’s peak arrived nearly one month earlier than usual, breaking the 2020-2025 pattern where annual peaks concentrated in June and July. Guangxi and Hainan provincial power grids also set new records simultaneously on the same day.

Li Zhiyong, Operations Planning Manager at the China Southern Power Grid Dispatch Center, attributed the early record to converging factors: “This year’s high temperatures in South China have arrived significantly earlier, activating regional cooling loads ahead of schedule. Combined with stable full-capacity industrial production and surging consumer activity, multiple factors have converged to push electricity loads past historical extremes ahead of time.”

Structural Shift in Power Consumption

The early record reflects more than just weather — it signals fundamental changes in China’s energy consumption patterns. Li noted that the traditional daytime single-peak industrial-era electricity consumption pattern “has been completely broken, forming a new ‘three-peak parallel’ operational characteristic in the morning, afternoon, and evening.”

Data from the Southern Grid shows that 36 monitored data centers in Guangxi saw electricity consumption increase by 19.2% year-on-year in January-April 2026. New energy vehicle manufacturing surged 277.9%, while the lithium battery industry grew 17%, driving both industrial and residential charging demand.

National Outlook: 16 Billion Kilowatts

The National Development and Reform Commission confirmed on May 22 that this summer’s national maximum electricity load will reach approximately 16 billion kilowatts, an increase of about 90 million kilowatts from last year. As Guangming Net reported, NDRC Deputy Director Li Chao described this as “equivalent to adding the electricity load of an entire Henan Province.”

The National Energy Administration has forecast that under extreme weather scenarios, the peak could exceed 16 billion kilowatts. Liu Mingyang, Deputy Director of the NEA’s Electricity Department, warned that East China, Central China, and South China will experience periodic heatwaves that “may drive rapid release of air conditioning cooling loads.”

Power Supply Readiness

Authorities have taken proactive measures to ensure supply. As of end of April, national coal reserves at regulated power plants reached approximately 200 million tons — over 30 days of supply — and hydropower storage exceeded 80 billion kWh, at historically good levels. From January to April 2026, approximately 100 million kW of new generation capacity was added nationwide. The Southern Grid has deployed 6.6 million kW of new energy storage, equivalent to the consumption of a second-tier city, and its renewable energy generation has grown more than 20% year-on-year.

El Niño and Climate Context

The heatwave arrives as the National Climate Center predicts an El Niño event will begin in May 2026, reaching moderate-to-strong intensity by summer and autumn. The China Meteorological Administration has confirmed that summer temperatures will be 0.5-1°C above normal across most of the country but has cautioned against alarmist claims of a “hottest summer ever,” as CCTV News reported.

What to Watch

With the summer peak arriving early and El Niño intensifying, China’s grid faces a prolonged test of resilience. The convergence of climate-driven cooling demand and structural economic shifts toward 24/7 industrial production, data centers, and electric vehicle charging means that peak loads may persist longer than historical norms. Officials have adopted a “one province, one policy” approach to grid management, but the question remains whether the system can withstand simultaneous extreme heat across multiple regions.
