Bangladesh: Growth in Electricity Transmission Network [free access]

February 11, 2019

As of June 2018, Bangladesh’s transmission network comprised 11,035 km of line length at the 132 kV, 230 kV and 400 kV voltage levels. Of the total line length, the majority, or about 63 per cent, was at 132 kV. The country’s grid is interconnected with that of India through two high voltage transmission systems. Since 2014, Bangladesh’s high voltage line network has increased at a CAGR of 4.3 per cent.
