The combined loads peaked at an all-time high of 16,665 megawatts, while the total consumption also hit a record 345 million kWh, up roughly 12% compared with the highest levels of 2017 and beating the previous records set on June 22.
In the capital of Hanoi, the total loads also hit a record high of 3,987 megawatts and total usage reached 79.3 million kWh.
Most of the electricity was supplied for air-conditioners and other cooling equipment, leading to overloads and power cuts in several locations.
According to the national weather service, temperatures as high as 40C and above will continue for another two to three days.
Therefore, EVN has advised its customers to use electricity economically and avoid using high-power electrical appliances, such as air-conditioners, electric cookers and water kettles, simultaneously.
The utility added that air-conditioners should not be set lower than 26C in order to save energy, reduce the risk of overloads and prevent a surge in electricity bills.
