The power sector is repairing damage caused by natural disasters.

Electricity workers in Muong Nha are repairing damage caused by natural disasters.

In Muong Nha district, due to the prolonged heavy rains and floods, the power grid system in the district has been severely affected. Several power poles have been damaged, with landslides posing a risk of power grid failures; floodwaters have eroded and caused power poles to collapse, with landslides affecting the pole foundations (pole 347 of the 35kV line 371 E21.7; pole 12 of the 35kV line NR Phu Ma; pole 2.2 of the 0.4kV line at Hui To 2 substation; pole 2.12 of the 0.4kV line at Pa My substation…). Muong Nha Power Company has implemented measures such as: For locations with landslides affecting pole foundations, the unit has dug drainage ditches to prevent rainwater from directly flowing into the pole foundations, and continues to monitor and respond accordingly. In areas affected by erosion, after the water recedes, sluice gates are constructed to redirect the water flow, preventing it from directly hitting the column foundations. Replacement columns are erected in place of fallen ones, and personnel are assigned to regularly inspect and monitor them during periods of rain, wind, and storms.

Currently, Muong Nha Power Company manages and operates 406.85km of 35kV power lines, 192.34km of 0.4kV power lines, and 144 distribution substations with a total capacity of 13,410kVA; and serves 10,328 customers. Due to the large geographical area, the unit faces many difficulties in troubleshooting, especially at locations with serious landslides and on inter-commune/inter-village/hamlet roads that have not yet been invested in or paved with concrete.

Mr. Pham Ba Dung, Director of Muong Nha Power Company, said: "To promptly address the damage and impact caused by the floods, the unit mobilized all its personnel to work day and night. With the goal of ensuring safe and stable electricity supply for the people in the managed area, the workers, especially the Medium and Low Voltage Grid Management and Operation Team, always strive to overcome difficulties and effectively implement the plans developed by the unit. Thanks to this, there has been no interruption in electricity supply in the area managed by Muong Nha Power Company; the power supply has been continuously and stably maintained to serve socio-economic activities and the lives of the people."

Not only in Muong Nha district, but prolonged heavy rain has caused landslides affecting power pole foundations and above power lines, carrying soil, rocks, and trees, causing power grid failures; floodwaters have eroded and caused power poles to collapse in many other localities throughout the province. Many power infrastructure projects have been damaged, including: landslides affecting power pole foundations, with the risk of pole collapse at pole 39 of the 35kV Nam Ha line 371 E21.7 in Muong Toong commune (Muong Nha district); and pole 45 of the 35kV line 375 E21.2 in Thanh Nua commune (Dien Bien district). Prolonged heavy rain has also affected many low-voltage poles in Na U, Phu Luong, He Muong, Nam He (Dien Bien district); Chung Chai, Nam Ke, Suoi Voi, Muong Toong, and Quang Lam (Muong Nha district). In Ma Thi Ho, Si Pa Phin, Sa Long, Na Sang, Muong Muon (Muong Cha district); Cha Cang (Nam Po district)... these incidents disrupted electricity supply to over 17,000 customers. Prolonged heavy rain also caused landslides on the embankment, collapsing the protective wall behind the Nam Pay Hydropower Plant's control building. Landslides from the embankment also caused landslides onto the road leading to the Nam Pay Hydropower Plant's valve house...

To proactively address incidents caused by storms and heavy rains, before this year's rainy season, Dien Bien Power Company developed specific disaster prevention and search and rescue plans tailored to each locality. Simultaneously, the company and its subordinate power branches organized disaster prevention and search and rescue drills to proactively handle and resolve incidents in real-world conditions quickly and safely. With a determined spirit to handle incidents in the shortest possible time according to the "4 on-site" principle and the "3 ready" principle, the power sector ensured continuous power supply, preventing prolonged power outages throughout the province.
