Speaking at the government's monthly meeting on June 3, Hung said peak demand in northern Vietnam had reached 30.5 gigawatts, compared with a maximum supply capacity of about 31 gigawatts.
The sharp increase has raised concerns over power supply during the remainder of the year as economic growth accelerates, industrial production expands and weather conditions remain unpredictable.
The Ministry of Industry and Trade said it was implementing measures on both the supply and demand sides to maintain the stability of the national power system.
Among the measures under consideration are adjustments to demand-response programmes aimed at encouraging businesses to shift electricity consumption away from peak hours, particularly in the evening.
Hung said the measures could affect some manufacturers operating during peak periods but were necessary to optimise available power resources, reduce pressure on the grid and ensure a stable electricity supply.
The ministry has also urged government agencies, local authorities and large power consumers to support efforts to manage demand during periods of high consumption.
According to Hung, contingency plans have already been prepared to cope with rising electricity demand and potential disruptions linked to weather conditions and developments in energy markets.
Vietnam has faced repeated power supply pressures during periods of extreme heat in recent years, particularly in the country's northern region.
