Vietnam Electricity Group said extreme heat is expected in northern Vietnam this month, likely pushing its maximum power producing capacity to over 27,000 megawatts, equal to 52% of the nation’s total, according to a new report.

The region, which plays a significant role in the global electronics supply chain, experienced major blackouts last year because of hot weather and malfunctions at coal-fired plants.

“We see no issues in power supply for the whole year,” a utility representative said in an email. Vietnam’s average daily power consumption in July may climb 10.2% year-on-year to 920.5 million kilowatt-hours, EVN said.

Vietnam’s coal electricity output jumped to 86.3 billion kilowatt-hours this year through June, representing 57% of the nation’s power mix, up from 49.5% a year earlier.

In an effort to reduce the risk of future electricity shortages and the nation’s reliance on coal-fired power, Vietnam earlier this month allowed major users to begin buying renewable energy directly from developers, bypassing the state monopoly.

The utility continues to ask customers to set air conditioners’ temperatures at no less than 26°C and refrain from using multiple high-capacity electric devices at the same time, especially during peak hours of 11am-3pm and 7pm-11pm.
