Ban Ve Hydropower Plant is ready to respond to Typhoon No. 3 (YAGI).
Given the unpredictable developments of Typhoon No. 3 (YAGI), Ban Ve Hydropower Company has prepared plans and strategies to respond and ensure the safe operation of the plant, reservoir, and downstream areas.
In accordance with the Operational Order of the Steering Committee for Disaster Prevention, Search and Rescue and Civil Defense (PCTT-TKCN-PTDS), today (September 5th), Ban Ve Hydropower Company issued a plan to respond to typhoon No. 3.
According to Mr. Ta Huu Hung, Director of Ban Ve Hydropower Company: Currently, the unit's leadership has instructed departments, divisions, and individuals to regularly monitor and update the storm's developments through mass media; implement plans to respond to heavy rain, proactively respond to all situations that may arise, especially landslides and flash floods caused by heavy rain; and always be ready to carry out disaster prevention and control tasks when required, ensuring uninterrupted communication 24/7.
Specifically, the Administration and Labor Department is responsible for coordinating with other departments and workshops to inspect all materials, equipment, and vehicles to ensure they are not flooded during heavy rains; ensuring sufficient resources and materials according to the "four on-site" principle at the drawing site; inspecting and reviewing vulnerable areas, preparing equipment, machinery, materials, food, medicine, etc., to ensure sufficient supplies for at least 5 days; and arranging transportation for employees on duty at the factory for disaster prevention and control on September 6, 2024.
In addition, the company's leadership assigned the Technical and Safety Department to take the lead and coordinate with the operating and production workshops to monitor the storm's progress, forecast and calculate the amount of water flowing into the reservoir, and to coordinate and promptly grasp operational information from the Khe Bo Hydropower Plant to advise the company's leadership on reasonable and effective reservoir operation plans; to inspect the power source systems (35kV grid, self-use, diesel) to ensure good operation when required; to inspect the communication system, including the internal communication system and communication points with local authorities and superior units; to implement the reporting regime to relevant authorities as prescribed; and to fully update meteorological and hydrological information and reservoir operation information on the websites of the Ministry of Industry and Trade and EVN.
In addition, in coordination with Ha Lam 276 Construction Co., Ltd., the unit responsible for the regular maintenance and repair of the road and bridge systems, they organized the clearing of drainage ditches and immediately addressed any landslides (if any) to ensure smooth traffic flow, and were ready to implement the plan to dismantle the Bailey bridge when required.
According to the report, at 9:00 AM on September 5, 2024: the water inflow into Ban Ve reservoir at 9:00 AM on September 5, 2024 was 274m³.3/s; water level in Ban Ve reservoir is 193.84m; discharge through turbines and spillway is 327m3/s. Forecast for the next 24 hours: The maximum inflow into the reservoir is likely to reach 350m.3/s up to 380m3/S.
Previously, also on September 5, 2024, the Provincial Steering Committee for Flood and Storm Prevention, Control, and Disaster Relief issued an Operation Order to Ban Ve Hydropower Company. This order instructed the Director of Ban Ve Hydropower Company to operate the reservoir, releasing water downstream at a flow rate greater than the inflow to the reservoir, gradually lowering the water level to the regulated elevation of 193m. The order was to be implemented at 8 PM on September 5, 2024. The discharge flow through the structure was 400m³.3/s to under 1,000m3/S.
During the operation to lower the reservoir water level, if the water level at the Con Cuong Hydrological Station exceeds alarm level I but remains below alarm level II, or the inflow into the reservoir is less than 1,000 m³.3/s up to 1,200m3The system then operates to release water through the structure at a flow rate equal to the inflow into the reservoir to maintain the reservoir water level.
During the process of lowering the reservoir water level, if a flood occurs causing the inflow into the reservoir to increase above 1,200 m³,3If the water level at the Con Cuong or Cho Trang Hydrological Station exceeds alarm level II, the Director of Ban Ve Hydropower Company shall operate flood control and reduction measures for the downstream area as prescribed. During the operation of flood control and reduction for the downstream area, if the reservoir water level is likely to reach 200m, the discharge flow through the structure shall be gradually adjusted so that when the reservoir water level reaches 200m, the discharge flow through the structure equals the inflow of floodwater into the reservoir, and the system shall switch to a mode ensuring the safety of the structure.
When the inflow into the reservoir decreases to below 1,000m³.3/s and with no possibility of increasing again, it operates under normal conditions.
