Electricity consumption in several parts of northern Vietnam has hit an all-time high because of an intense heatwave that raised the overall temperature in the region.
The total power consumption in 17 northern provinces and cities, managed by the Northern Power Corp (EVNNPC), reached 393.09GWh on 4 August, hitting a new record after the demand reached 389.39GWh on 18 July, EVN said. EVNPC is a unit of EVN. The data does not include supplies to the capital city of Hanoi, which is managed by EVN Hanoi, another subsidiary. Power demand in Hanoi has also surged to a year-to-date high of 122.8GWh on 4 August, the utility said.
The power demand rose on the back of an increase in air conditioner usage as temperatures increased in various parts of northern Vietnam because of heatwaves in the region. Temperatures were above 39°C in some regions, and the hot weather conditions were exacerbated by high humidity. The school holidays also contributed to an increase in household power demand, EVN said.
The increase in power demand could support coal burn at utilities and overall demand for seaborne coal. Vietnam's overall coal imports reached 38.11mn t in the first half of the year, up by 14pc from the same period a year earlier, according to Vietnamese customs data. Coal-fired generation accounts for the bulk of Vietnam's power output.
Power saving
EVN has advised local authorities, businesses, commercial and residential consumers to ensure economical and efficient use of electricity.
It has asked commercial units and households to reduce consumption, and advised them to not set air conditioner temperatures below 26-27°C.
Vietnamese authorities have asked power consumers to pay special attention to electricity usage during peak hours of 1:00pm-3:00pm local time (6:00am-8:00am GMT) and 8:00pm-11:00pm. Authorities anticipate rain in coming days could help lower the temperature and ease some power demand.
