State-owned Electricity of Vietnam (EVN) has said the country's 20 major hydropower plants will have to cut back on production to prevent water levels at reservoirs from falling too fast and damaging equipment.
The plants, with a combined capacity of 6,200 megawatts, will only be able to produce 50 million kilowatt-hours per day during the dry season, much lower than the usual output, EVN officials said.
They said the national power utility will instead raise output at thermal power plants and increase purchases from other producers to offset the shortage.
Power demand in Vietnam is set to rise 18 percent this year on the back of an economic recovery. The lack of water in reservoirs will translate into a loss of nearly 1 billion kilowatt-hours of electricity at hydro power plants, the government said in a statement Monday.
EVN has said it will give priority to supplying power for the manufacturing sector and important social events.
