The Hanoitimes - Hanoi managed to save around 50 million kWh of electricity during the first half of this year, equivalent to 1.12 per cent of the capital's yearly power supply, according to a municipal electricity company (EVN Hanoi) report.
The country's second largest economic and financial centre consumes an average of 15 million kWh of electricity a day.
Power consumption usually soars between June and July, the city using 38.5 million kWh of electricity on July 6 alone and 30.8 million kWh on June 30.
EVN Hanoi's sales department Director Nguyen Anh Tuan said that the increase in electricity consumption occurred due to the simultaneous use of appliances in hot temperatures.
"Families should not use multiple electrical appliances at the same time, particularly during peak hours, in order to ensure a stable power supply throughout the city," he said.
