China's record heat drives power demand to a new high

Energy officials reported that days of record-breaking heat in large parts of China drove power demand up to a new high of more than 1.5 billion kilowatts.

A sweltering arc of heat stretches from the densely-populated southwest cities of Chongqing, Chengdu and Guangzhou to the southern megaport. Meteorologists attribute this extreme to climate change. It presents a challenge to authorities.

State media reported on Thursday that temperatures reached their highest level ever at eight weather stations over the past two days, thanks to a subtropical weather system in the southwest and northwest.

Chim Lee is a senior energy specialist and climate change specialist with the Economist Intelligence Unit.

The real test comes as summer progresses, and there is still the risk of power rationing.

Lee stated that the surge in June power generation was largely due to solar energy. The hydropower production nationwide increased over 2023 but was still lower than 2022.

China's National Energy Administration announced on Wednesday that the country's electricity load had reached a "record-high" for the third consecutive month.

This was an increase by 55 million kilowatts compared to last year's record. Since the summer started, 36 provincial records have been broken in the second largest economy.

Temperatures above normal can cause cropland to scorch and farm incomes to plummet. They can also disrupt manufacturing hubs, and affect key ports. This puts a strain on already overburdened health care.

State media reported that in the last decade, Jiangxi province, located in southern China, has averaged 21.7 days per year with temperatures over 28 degrees Celsius. This is up from 5 to 7 at the turn-of-the century.

In a blog last week, state broadcaster CCTV highlighted a traditional of sleeping with wax gourds. These vegetables are believed to be effective at absorbing heat.

The official news agency Xinhua reported that iced watermelons were served to zoo animal in Chongqing on Wednesday.

However, there is the possibility of some relief.

The weather forecasters predict temperatures will begin to ease from Monday as a tropical disturbance east of the Philippines could strengthen into a storm that is expected to be called Wipha and track across Taiwan towards southern China.

The subtropical high could block the low-pressure systems, causing air conditioners to run at full speed and further stressing the electricity grid.
