Da Nang requests limited power generation at five hydroelectric reservoirs

The Da Nang People's Committee has requested the National System and Market Operator (NSMO) to minimize or cease power generation at five hydroelectric reservoirs: A Vuong, Song Bung 2, Song Bung 4, Dak Mi 4A, and Song Tranh 2. This measure is intended to prioritize water accumulation through November 11, 2026, to prepare for potential water shortages in 2027.

Currently, water levels in these reservoirs on the Vu Gia - Thu Bon river basin are critically low. For instance, the Song Tranh 2 reservoir level is 27 meters lower than the same period last year. Authorities are concerned that the El Nino phenomenon could lead to severe drought, water scarcity, and saltwater intrusion in the downstream areas.

By maximizing water storage during the upcoming rainy period, the city aims to ensure a stable supply for agriculture, domestic use, and essential needs during the 2027 dry season. The risk is heightened by the possibility of delayed rainy seasons and reduced upstream flows.
