Investigation committee of the state-owned Power Grid Company of Bangladesh (PGCB) has started its probe to identify the reasons behind the national power grid failure that triggered a seven-to-eight-hour long blackout across most of the country, starting at 2:04 pm yesterday (October 4, 2022).

The country yesterday suffered the worst power outage in eight years, which, according to officials, was triggered by a trip at a substation in Ghorashal.
