At around 7:40 p.m., a loud explosion occurred at the 500 kV transformer station in Tan Thinh ward, Hoa Binh city, belonging to Power Transmission Company 1 (National Power Transmission Corporation - EVNNPT), followed by many sparks flying into the air before turning into a fire.
A resident living about 2 km from the Hoa Binh hydroelectric plant said the fire lit up the sky, and from afar the area of fire and the surrounding mountainside could be clearly seen. The fire was completely extinguished in about 15 minutes.

The incident did not cause any human casualties, and power was restored to the areas that lost power shortly after. Vietnam Electricity Group said that Power Transmission Company 1 had separated the transformer from the system to ensure safe operation of the national power transmission system.
EVNNPT mobilizes backup transformers for replacement as soon as possible to ensure power system operation.
The cause of the incident is being investigated and clarified by Power Transmission Company 1.
