Experts forecast that multiple cities in China will experience extended period of extreme heat in August, with authorities proactively taking measures such as turning off display lights to address challenges posed by peak electricity consumption.

With blistering heat set to once again descend over China, Jia Xiaolong, deputy director from China's National Climate Center (NCC), suggested that the relevant authorities should be ready to make preparations for the energy supply during peak period for electricity consumption, Xinhua News Agency reported.

Hangzhou in East China's Zhejiang Province has implemented measures such as pausing non-essential landscape lighting and suspending light shows from Monday to Friday to manage the power load during the ongoing extreme heat wave, local authorities announced on Tuesday.

The West Lake, a famed attraction located in Hangzhou, will temporarily suspend the power-generating musical fountains from August 6 to August 9, the site's management department said on Tuesday.

According to the State Grid Zhejiang Electric Power Co Ltd, the average household electricity consumption of Hangzhou residents in July totaled 549 kilowatt-hours (kWh), ranking first in the province, with 57 percent of the households doubling their electricity consumption from the previous month.

In July, Shanghai authorities released an electricity proposal, prioritizing household energy consumption, essential projects and business activities which support critical services. 

A district in Southwest China's Chongqing Municipality requested merchants to turn off their electronic advertising billboards from 12 pm to 8 am, suggesting that outdoor digital advertisings should be switched off or keep a low light level, an official from the local government announced in July.

East China's Jiangxi Province urged officials to avoid working with lights turned on during daytime or when offices are unoccupied and leaving the lights on all the time, according to an electricity conservation initiative issued by the local government.

Electricity conservation measures put in place by East China's Anhui Province suggested public institutions to act as standard bearers, such as setting the office air-conditioning higher than 26 C, suspending elevator access to low floors. Also, industrial enterprises are expected to voluntarily carry out staggered schedule for power use to minimize energy consumption and costs.

It is expected that in the first half of August, China will see two periods of extreme heat, of which August 3 to 7 searing heats in southern China will be featured by a wide range and high intensity. Temperatures in cities of East China's provinces, including Anhui, Jiangsu, Zhejiang and Jiangxi will reach 39 C to 42 C, Jia told Xinhua.
