According to the National Meteorology Forecasts Centre, as of November 22, water levels in central and southern reservoirs were 4.7 to 22 metres higher than dead-water levels.
Water levels in northern reservoirs, such as those at Hoa Binh, Tuyen Quang and Song Da hydro-power plants, were seven to 10 metres lower than the same period last year.
Dang Hoang An, deputy general director of EVN, said higher water levels had helped to bring hydro-power plants in Central Highlands and southern provinces to normal operations.
An said a number of thermo-power plants would be suspended for periodic maintenance in preparation for power generation in the dry season of 2011.
To avoid power cuts in peak hours, EVN would continue to purchase electric power from abroad and run plants using expensive fuels such as FO and DO.
He added that EVN had been making plans to release water from reservoirs to irrigate the spring crop in 2011.
EVN's subsidiaries, in coordination with irrigation companies in the Song Hong (Red River) Delta, had been inspecting the irrigations systems to receive sources of water from reservoirs and use them economically.
