The city used some 60 million kilo-watt hour (kWh) of electricity per day on an average during the first week of May when the temperature reached 37-38 degree Celsius, according to EVN.
On May 8, electricity consumption in the city reached 64.8 million kWh, much higher than the highest electricity consumption during the first quarter of the year, which was recorded at 48.56 million kWh on January 5.
It is also 20 per cent up from the highest electricity consumption in April, which was recorded at 50.5 million kWh on April 24.
Since more heat waves have been forecast, EVN Hà Nội has set up hundreds of transformers, electrical lines and substations to avoid grid overload.
It has also prepared several power supply options during the summer, the company said.
According to EVN, it will not cut power for maintenance purposes when the outside temperature is 36 degree Celsius or higher.
More operational staff will be assigned to be on duty to respond to customers’ inquiries during warm days, EVN said.
