A fire broke out at the main power grid line in Satkhira, disrupting electricity supply in the district since Saturday morning.
According to Fire Service sources, the fire erupted at the Binerpota 132/33 kV power grid line around 11:10am when a transformer exploded with a loud bang.
Upon receiving the information, two firefighting units rushed to the spot and brought the blaze under control after about an hour.
No casualties were reported. Russel Islam, in-charge of Satkhira power grid line, said the explosion caused a complete power outage across the district.
Efforts are underway to restore electricity, and supply is expected to return to normal by the evening, he added.
