New Delhi, Sep 28 (TIWN) A growing power supply crunch in China is triggering blackouts for households and forcing factories to cut production, threatening to slow the country's vast economy and place even more strain on global supply chains, CNN reported.

Companies in the country's industrial heartlands have been told to limit their energy consumption in order to reduce demand for power, state media reported. And supply has been cut to some homes, reportedly even trapping people in elevators, the report said.  An "unexpected and unprecedented" power cut hit three northeastern provinces on Monday, according to the Global Times, a state-run tabloid. The newspaper reported Tuesday that power rationing in Heilongjiang, Jilin, and Liaoning provinces has "resulted in major disruptions to the daily lives of people and business operations."
