On the morning of August 5, Hanoi Power Corporation (EVN Hanoi) said that in just the past 4 days, consumption output has increased by more than 25.5 million kWh, equivalent to 26.5%.
This clearly reflects the sudden increase in the use of cooling devices such as air conditioners, refrigerators, fans, etc. in extreme weather conditions. This is also the highest output level since the beginning of the year in Hanoi.
Not only output, the city's electricity consumption capacity also continues to break previous records.
In particular, if on July 30, 2025, the consumption peaked at 5,608.6 MW, then less than a week later, at 1:44 p.m. on August 4, 2025, the capacity continued to set a new peak with the figure of 5,992 MW - an increase of 6.8% in just 5 days and an increase of nearly 14% compared to the peak in 2024.
The main reason for the high consumption is the continuous hot weather for many days, combined with summer vacation, which prolongs the time of using electrical equipment in the family, especially the cooling equipment group. Equipment such as air conditioners often have to operate at full capacity to maintain a stable temperature, causing electricity consumption to increase sharply even when the usage period remains unchanged.
According to the Berkeley Research Institute, California, USA: devices that have not been retracted, even if not used, will still consume about 5% - 10% of the electricity consumed in the family.
Faced with a record high in electricity output, EVN Hanoi said that there is no schedule to temporarily suspend power supply as planned during the extremely hot weather period.
This unit recommends that customers, offices and production places join hands to use electricity economically and efficiently, turn off unnecessary electrical equipment and limit the use of high-capacity equipment during peak consumption hours from 12:00 ÷ 15:00 and from 22:00 ÷ 24:00 daily. At the same time, pay attention to reasonable use of air conditioners (reserved at 26°C or higher, used in combination with fans).
