The government is planning to set up another transmission line from Bheramara to Baharampur of India to import 1,000 megawatts of electricity from the neighbouring country.
The existing transmission line, through which 500MW power now being imported from India, won’t suffice to carry the new 1,000MW electricity smoothly, although its capacity is being raised to 1,000MW, says the Power Division.
The Power Division has prepared a new project of Tk 188 crore and placed it at the Planning Commission for approval to construct the second double circuit 400kV line, the officials have said.
However, the Planning Commission has raised questions about the new plan, pointing fingers at power division’s weak plan to import power from India.
It said there should have been a proper plan to construct the first line with a higher capacity since the Power System Master plan 2010 seeks to import 3,500MW power from India.
Apart from wasting money, the 28kms new transmission line will also waste land because of the poor-planned construction of the first transmission line, observed the Commission.
“Constructing the second line would not have been necessary, had the 30kms first line was constructed with 1,000MW transmission capacity,” the Commission said in its project evaluation report.
In a meeting of the 11th Joint Working Group (JWG) held in Dhaka on July 13 last year, officials of both the countries agreed to construct the second transmission line, official sources said.
Accordingly, the Joint Technical Team (JTT) conducted a survey on the proposed new line and prepared a detail project report (DPR).
Now, Bangladesh is importing 500MW of power from India through a High Voltage Direct Current (HVDC) Back-to-Back station and Bheramara-Baharmpur 400kV double circuit transmission line through a the India-Bangladesh power grid interlink.
A project is also underway to raise the existing HVDC back-to-back station’s capacity from 500MW to 1,000MW, but the power division says it won’t be enough to ensure uninterrupted transmission of another lot of 1,000MW power.
The Power Grid Company of Bangladesh (PGCB) wants to construct the new line by June next year.
For the new transmission line, aluminum conductor steel re-inforced (ACSR) Twin Finch wire will be used in Bangladesh portion and the same category Twin Moose wire will be used in India portion, although PGCB usually uses aluminum conductor composite core (ACCC).
In addition to the transmission line, two 400kV bays will be expanded in the existing 400/230kV sub-station in Bheramara under the new project being processed at the Planning Commission.
