The National Power System Dispatching Centre has asked selected hydropower plants to increase hydroelectricity generation and discharge water to ensure the safety of reservoirs. The Lai Chau, Huoi Quang, Trung Son, Khe Bo, Ba Ha River, An Khe, Srepok 3, and Buon Kuop hydroelectric reservoirs started to discharge water on August 7.
The Vietnam Electricity Group said that heavy rains over the past seven days in the northern region, with rainfall reaching between 150-250mm per day have led to a sharp rise in water level at local hydroelectric reservoirs.
Flash floods and landslides triggered by the prolonged rains have also damaged pylons and cables and affected the operation of some hydropower plants in the northern region.
Some areas in the Mu Cang Chai District in Yen Bai Province suffered power cuts after some facilities of the Ho Bon Hydropower Plant were damaged by flash floods and landslides.
The same problem occurred in some districts of Muong La and Quynh Nhai in Son La Province. Local authorities are trying to fix the situation and expect to supply power again to these areas by August 9.
In the Central Highlands Province of Dak Nong, two hydropower plants in Gia Nghia City, the Dak R’Tih and Dak Nong 2, also faced landslides in some areas. The Dak Nong 2 plant had to temporarily suspend operation for repair work.
