According to a quick report from Thai Nguyen Electricity Company, by 12 noon on October 7, the 110kV power grid including the 110kV Thinh Dan transformer station and the 110kV Xi Mang Thai Nguyen transformer station had to cut off power urgently due to severe flooding.

Damage to the medium voltage grid: A total of 36 medium voltage lines were damaged and flooded, causing power outages in many areas. A serious landslide at pole 46 of the 373 E26.1 main line caused a 30m high steel pole to tilt and fall. This is the line supplying electricity to Cho Moi district, Na Ri district (old) and Bac Kan ward. Many localities were severely affected, such as: Cho Moi, Na Ri, Ba Be, Bac Kan, Phu Luong, Dinh Hoa, Vo Nhai, Thai Nguyen city (old)..., with about 10 poles broken and fallen due to heavy rain and landslides.

The 35kV line has fallen poles, trees in the corridor are at risk of falling and causing an incident; some branches and 22kV and 0.4kV lines are affected by landslides and flooding. The unit has handled, isolated the incident and restored power to 1,643/1,694 customers; 51 customers have not been restored due to flooding. The unit is continuing to monitor the weather and check the power grid.
