Probe body starts work to find out reasons for national grid failure

Staff Reporter :
The investigation committee of the state-owned Power Grid Company (PGCB) of Bangladesh formed to identify the reasons behind the national power grid failure that triggered a seven to eight hours long blackout in five divisions of the country, starting at 2:04pm on Tuesday, has started its function.
"We have started our investigation work from toady 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 team and executive director (P&D) of PGCB, told The New Nation on Wednesday.
However, people from all walks of life, especially patients in different hospitals, elderly people and children, suffered heavily as the country's central and southeastern regions-including capital city Dhaka, Mymensingh, Chattogram, Khulna and Sylhet divisions-plunged into darkness following Tuesday's massive blackout due to failure of the national grid. Power supply to the country's central and southeastern region, came to a halt at around 1:30pm on Tuesday.   Production of industrial units came to a halt for about eight hours and city people suffered from getting water as their water pumps went out of order due to power failure.
Telecommunications services including internet were disrupted following the power outage across the country.
People from different offices and organizations were seen to collect diesel from petrol pumps to operate their generators.
Meanwhile, the state-owned PGCB formed a 5-member investigation committee on Tuesday night, headed by Yakub 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 massive collapse of power due to the national grid failure.
Later, an experienced individual who had been working as consultant with grid systems locally and internationally, was 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.
According to the head of the probe committee, "It might take more time to reach a conclusion, as this involves a lot of technical issues of the grid system."
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.
Those two committees are yet to be formed, said an official of Power Division.  
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 10:30pm, the entire country had electricity.
PGCB officials said the country's power supply demand was relatively lower at around 8500 MW on Tuesday as the weather was not hot.
Bangladesh's biggest incident of national power grid failure happened on 1 November in 2014 when the entire country was without power for 17 hours.
