Record temperatures scorch eastern China, spiking power demand
BEIJING — Eastern China is baking under unseasonably high temperatures, with the excessive heat expected to linger in mega coastal cities in the highly industrialized provinces of Jiangsu and Zhejiang for up to 10 more days.
In the east and northwest of China, temperatures as high as 43.9 degrees Celsius (111.02 degrees Fahrenheit) have scorched Zhejiang, Jiangsu, Shanghai, Anhui and Xinjiang in recent days, state broadcaster CCTV said.
On the coast, Zhejiang’s provincial capital, Hangzhou, recorded a historical high of more than 107F on Saturday. The city of 12.5 million people is expected to swelter under temperatures exceeding 104F through Sunday.
In nearby Shanghai, the maximum load, or demand, on its power grid exceeded 40 million kilowatts for the first time on Friday as 104F temperatures increased electricity consumption in the city of nearly 25 million people, according to industry news outlet BJX.com.
Chinese meteorologists say the record heat this year has been aggravated by high continental temperatures owing to global warming, even as the weather phenomenon La Niña brings cooler-than-average sea surface temperatures in the equatorial Pacific.
Earlier this year, China was hit by its warmest spring since 1961, when it started to compile modern-day data. That was followed by the country’s hottest May, setting off weeks of drought-like conditions in central China in June, hitting crops and livelihoods of farming communities in the region.
With the extreme heat this summer, electricity usage has also risen due to increased demand for air-conditioning. The spike in electricity demand could threaten a supply crunch.
Zhejiang’s State Grid since last month began recommending electric vehicle owners charge their vehicles late at night to stagger electricity use from daily peak hours.
It also advised people to turn off air-conditioning when temperatures were milder.
The national weather forecaster on Monday cautioned of potential fire hazards caused by excessive power consumption and excessive electrical loads.
In the coming days, many areas around the Yangtze River delta can expect sizzling weather of above 98F after daily maximum temperatures at seven national weather stations breached local historical extremes.
Jiangsu’s observatory issued a red warning for heat on Sunday after high temperatures that had persisted for more than a week further intensified. The mercury could reach 104F in the cities of Wuxi, Changzhou and Zhenjiang, CCTV said.
Hangzhou is expected to see 10 straight days of above 104F weather, breaking its record of eight days in 2013.
