BEIJING, Sept 28 — Goldman Sachs today lowered its annual economic growth forecast for China as nationwide power cuts hit millions of homes and halted production at factories, including some supplying Apple and Tesla.

At least 17 provinces and regions — accounting for 66 per cent of the country’s gross domestic product — have announced some form of power cuts in recent months, mainly targeting heavy industrial users, according to Bloomberg Intelligence.

Nearly 60 per cent of the Chinese economy is powered by coal, but supply has been disrupted by the pandemic, put under pressure by tough emissions targets and squeezed by a drop in coal imports amid a trade tiff with Australia.

Earlier this month, coal prices hit a record high, with restrictions imposed on businesses and homes amid the supply crunch.

Still, China’s power demand in the first half of the year exceeded pre-pandemic levels, according to the National Energy Administration. 

Goldman Sachs said today it expects growth to come in at 7.8 per cent, down from 8.2 per cent, citing power cuts that led heavy industries to cut output, leading to "significant downside pressures”.

It is the second bank to downgrade forecasts in as many days. 

Analysts at Nomura said Monday a surging number of factories had been forced to cease operations due to either government mandates to meet carbon targets or surging prices and coal shortages.

It cut its annual GDP growth forecast to 7.7 per cent.

Apple supplier Unimicron Technology said factories in two regions were told to stop production from midday Sunday through Thursday.

Dozens of other companies, including a parts supplier to carmaker Tesla, were told to halt production this week, according to stock exchange filings.

And in Beijing, utility giant State Grid told AFP today that a series of upcoming power outages in the capital — which will last nearly 10 hours at times — are part of a "planned maintenance”, a statement that appeared to downplay state media reports that they are due to the nationwide power crunch.

The northeastern rust belt, with thousands of power-hungry cement kilns and steel smelters, has been among the areas worst affected.

A factory in northeast Liaoning had to rush 23 workers to hospital due to carbon monoxide poisoning after ventilators suddenly stopped working during a blackout, state broadcaster CCTV reported.

Footage on local media Beijing News showed cars travelling a busy highway in the city of Shenyang in complete darkness without traffic lights or street lamps. 

"Power cuts eight times a day, four days in a row... I’m speechless,” wrote one frustrated user from Liaoning. 

Another complained that malls were shutting early and a convenience store was using candlelight.

"It’s like living in North Korea,” they wrote. — AFP
