Faced with the unpredictable developments of storm No. 3 (YAGI), Ban Ve Hydropower Company has prepared plans and strategies to respond, ensuring safe operations of the plant, reservoir and downstream areas...
Implementing the Operation Order of the Steering Committee for Natural Disaster Prevention, Search and Rescue and Civil Defense (PCTT-TKCN-PTDS), today (September 5), Ban Ve Hydropower Company issued a plan to respond to storm No. 3.
According to Mr. Ta Huu Hung - Director of Ban Ve Hydropower Company: Currently, the unit's leaders have requested departments, offices and individuals to regularly monitor and update the storm's developments on mass media; Deploy plans to respond to heavy rain, proactively respond to all situations, especially landslides and flash floods caused by heavy rain; Always be ready to perform natural disaster prevention and control tasks when required, ensuring 24/7 communication.
In particular, the Administrative and Labor Department is responsible for presiding over and coordinating with departments and workshops to check all materials, equipment, vehicles, etc. to ensure that they are not flooded when heavy rain occurs; Ensure sufficient means and materials, etc. according to the "4 on-site" motto in Ban Ve; Check and review key locations, prepare means, machinery, materials, food, medicine, etc. to ensure enough for at least 5 days; Arrange vehicles to transport employees on duty to prevent and fight natural disasters at the factory on September 6, 2024.
In addition, the company's leaders also assigned the Technical and Safety Department to preside over and coordinate with the operating workshops and production workshops to monitor the storm's developments, forecast and calculate the amount of water flowing into the reservoir, and at the same time, coordinate and promptly grasp the operational information of Khe Bo Hydropower Plant to advise the company's leaders on reasonable and effective reservoir operation plans; Check the power source system (35kV grid, self-consumption, diesel) to ensure good operation when required; Check the communication system, including the internal communication system, communication points with local authorities and superior units; Implement the information reporting regime to the authorities according to regulations; Fully update meteorological and hydrological information, reservoir operation on the websites of the Ministry of Industry and Trade, EVN.
In addition, we also coordinate with Ha Lam 276 Construction Company Limited, the unit that regularly maintains, repairs and operates the road system, traffic bridges, organizes the dredging of sewers, and immediately handles landslides (if any) to ensure smooth traffic, and is ready to deploy the plan to dismantle Bailey Bridge when required.
According to the report, at 9:00 a.m. on September 5, 2024: the water flow to Ban Ve Lake at 9:00 a.m. on September 5, 2024 was 274m3/s; Ban Ve lake water level is 193.84m; discharge flow through the generator and spillway is 327m3/s. Forecast in the next 24 hours, the maximum flow to the lake is likely to be at 350m3/s to 380m3/S.
Previously, also on September 5, 2024, the Provincial Steering Committee for Disaster Prevention, Search and Rescue and Disaster Prevention sent an Operation Order to Ban Ve Hydropower Company. In particular, the order ordered the Director of Ban Ve Hydropower Company to operate the 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.
During the process of lowering the lake water level, if the water level at Con Cuong Hydrological Station exceeds alarm level I but is still below alarm level II or the flow to the lake is from 1,000m3/s to 1,200m3/s then operate the water discharge through the project with the same flow rate as the flow to the lake to maintain the lake water level.
During the process of lowering the lake water level, if a flood occurs causing the flow to the lake to increase to over 1,200m3/s or the water level at Con Cuong Hydrological Station or Cho Trang exceeds the alarm level II, the Director of Ban Ve Hydropower Company shall carry out flood reduction and cutting operations for downstream areas according to regulations. During the flood reduction and cutting operations for downstream areas, if the reservoir water level is likely to reach 200m, the discharge flow through the project shall be gradually adjusted so that when the reservoir water level reaches 200m, the discharge flow through the project shall be equal to the flood flow to the reservoir and the project shall be switched to safety assurance mode.
When the flow to the lake decreases below 1,000m3/s and is not capable of increasing again under normal operating conditions.
