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 7-8 hour long blackout across most of the country, starting at 2:04 pm on Tuesday, reports UNB.
“We started our probe on Wednesday morning to identify the possible causes behind the national grid disaster and also the exact point of the incident,” Eakub Ehalhi Chowdhury, chief of the investigation body and executive director (P&D) of PGCB.
PGCB initially formed a 5-member investigation committee, headed by Eakub Elahi Chowdhury, representatives from Bangladesh Power Development Board (BPDB), Bangladesh University of Engineering and Technology (BUET) and also from other power sector entities, following the national grid failure.
An experienced individual who had been working as consultant with grid systems locally and internationally was also co-opted in the committee.
Eakub informed that the committee will visit substations and power stations and other relevant facilities to identify the reasons behind the grid-collapse.
Official sources said the investigation committee was given three days’ time to complete the probe.
“It might take more time to reach a conclusion, as this involves a lot of technical issues of the grid system,” Eakub added.
Meanwhile, State Minister Nasrul Hamid instructed the ministry of power, energy and mineral resources to form two more investigation committees to identify the cause of the grid failure and also gave recommendations to avert any further disaster in future.
PGCB and BPDB officials believe that Tuesday's grid disaster started from somewhere in Ashuganj-Sirajganj interconnecting transmission line that led to a colossal shutdown of power plants across the country.
After a relentless effort of 3 hours, PGCB first became successful in restoring power in Kalyanpur grid sub-station and then restored power supply in the president's official residence of Bangabhaban and Prime Minister’s official residence of Ganabhaban at 5 pm.
Gradually, power supply was restored in other parts of the area and within 10:30 pm, the entire country had electricity.
