Tripping of the Bheramara grid sub-station caused the entire national electricity grid to collapse on November 1, according to the report of a government committee formed to investigate the reasons.
The report is supposed to be submitted yesterday, but it could not be as State Minister for Power Nasrul Hamid was not in country.
Nasrul will return on November 24.
Mohammad Hossain, director general of the Power Cell and member secretary of the investigation committee, yesterday told the Dhaka Tribune: “We will place 20-point recommendations to the state minister about the blackout.”
Inefficiency of the maintenance staff of the national grid and widespread mismanagement had also contributed to the nationwide blackout, a government probe committee has found.
On November 12, the committee, formed by the Power Ministry, finished investigation by visiting the Ghorashal power plant at Narsingdi.
The eight-member probe body, comprising one former and seven current government high officials, said they would now analyse the data they had collected and submit a report within a few days.
On November 6 – a day after the first deadline expired – instead of submitting a report, the committee placed some “primary information” about the blackout to the state minister for power and sought 10 working days’ time.
Reportedly, the committee is still analysing the data it had collected by visiting the National Load Despatch Centre in the capital’s Aftabnagar, the Bheramara sub-station and the Ashuganj, Haripur and Ghorashal power plants.
On the day of the blackout, officials of the Power Grid Company of Bangladesh, the authority that owns and runs the national power grid, said the Bheramara sub-station tripped first and caused some power stations in Ashuganj to fail.
