Regarding the fire incident at Cai Lay 220kV Transformer Station (managed and operated by Power Transmission Company 4 under EVNNPT) causing widespread power outages in many areas of Long An and Tien Giang provinces on the evening of August 31, on the afternoon of September 1, the Southern Power Corporation issued an official document informing about the cause of the incident and the results of the remedial work.
According to the Southern Power Corporation, the fire at the Cai Lay 220kV transformer station that caused power outages in many areas of Long An and Tien Giang provinces was initially determined by local authorities to be caused by lightning striking the Cai Lay 220kV transformer, causing a failure of the 110kV transformer of the Cai Lay 220kV transformer. At the time of the incident, the area was experiencing heavy rain and thunderstorms.
Immediately after the incident, throughout the night of August 31, Southern Power Corporation and its member units, Long An Power Company and Tien Giang Power Company, coordinated with units under Power Transmission Company 4 to immediately implement a solution to transfer power overnight, in rainy and windy weather conditions to quickly fix the incident and restore power to each area for affected customers in the two provinces of Long An and Tien Giang.
By 4:00 p.m. on September 1, all customers affected by the incident had normal power supply restored.
Southern Power Corporation would like to apologize to customers for the objective incident that interrupted power supply and hopes to receive sympathy.
