Ban Ve Hydropower Plant opens 6 flood gates
Due to the amount of water flowing into the reservoir reaching 1,300m3/s, Ban Ve Hydropower Plant (Tuong Duong, Nghe An) has opened 6 gates to regulate water and reduce flooding for downstream areas as directed.
Talking to reporters, Mr. Ta Huu Hung - Director of Ban Ve Hydropower Plant, said: Due to the influence of storm No. 3 causing heavy rain, on the morning of September 8, the amount of water flowing into Ban Ve Hydropower Plant reservoir was 1,300m3/s. The current reservoir elevation is 193.4 m. Therefore, the Company is currently regulating water to reduce flooding in the downstream area according to the province's direction.
Currently, the factory is discharging at a flow rate of 670m3/s, including discharge over 500m spillway3/s, discharge through the unit 170m3/s and discharge all 6 gates, an increase of 4 gates compared to the previous day. Discharge time until the water flow is below 1,000m3/s will gradually close to accumulate water and operate according to regulations

Previously, also on September 5, 2024, the Provincial Steering Committee for Natural Disaster Prevention, Search and Rescue and Civil Defense sent an operation order to Ban Ve Hydropower Company.
In which, the order is for the Director of Ban Ve Hydropower Company to operate Ban Ve Hydropower Reservoir to discharge water downstream with a flow greater than the flood flow to the reservoir to gradually lower the reservoir water level to the water level of 193m as prescribed. The time to start implementing the order is 8:00 p.m., September 5, 2024. The discharge flow through the project is from 400m3/s to below 1,000m3/S.
To proactively respond and limit damage during the time Ban Ve Hydropower Plant operates to reduce flooding downstream, the Standing Office of the Provincial Steering Committee for Natural Disaster Prevention, Search and Rescue and Civil Defense requests units and localities to notify authorities, people, and organizations operating on rivers and riverbanks; Aquaculture facilities on rivers, water transport vehicles; Ferry terminals; Production, business, and sand and gravel exploitation activities to know information about the discharge of water from the hydropower reservoir to proactively take preventive measures to ensure safety for people and property.
Review flood prevention plans to ensure safety downstream, especially the dike system and residential areas on river banks to be ready to respond.
Direct information and communication agencies to increase the time and frequency of reporting on the media, especially the radio system in wards, communes and towns about the release of water from reservoirs; at the same time, coordinate with specialized agencies to guide flood prevention skills for people and relevant agencies and units to deploy response and minimize damage caused by the release of water from reservoirs.
