With the acceleration of the work and production resumption in Shanghai, many enterprises are seeing a rise of electricity consumption, with industrial enterprises above designated size rising steadily in the first three weeks of May to 83 percent of the levels in 2021 in average daily consumption, according to Shanghai authorities on Friday.

The company is actively responding to the demands of enterprises and will complete nearly 140 maintenance and technological upgrade projects before summer consumption peak approaches to ensure public safety, Ruan Qiantu, head of Shanghai branch of China's State Grid said on Friday's press briefing.

It also has established communication and services mechanism to provide "point-to-point" services for the "white-list" enterprises which have resumed production, according to Ruan.

Meanwhile, total electricity consumption in Shanghai continues rising to over 78 percent of the level in the same period in 2021, said Ruan.

The city has been making efforts to push forward further gradual steps to lift the lockdown and more businesses are expected to resume gradually under a regular epidemic preventive and control measures.

Shanghai on Thursday reported 45 COVID-19 cases and 219 asymptomatic cases,  all detected within regions under quarantine. Also, more than 21.7 million residents are under "prevention-level" regions which means they could be allowed to move freely within certain areas in certain time, according to authorities.

Some factories in Shanghai, from automakers,  biomedicine firms, to chip manufacturers, have been calling back staff to restore production to push businesses back on track under the city's epidemic preventive and control measures.
