The Japan International Cooperation Agency (JICA) has shown interest in financing the overhaul of two aging units at the Karnaphuli Hydroelectric Power Station, Bangladesh’s only hydropower plant, as the project remained stalled for more than seven years due to procurement complications.
Officials from the Bangladesh Power Development Board (BPDB) said preparations are underway to develop a detailed project proposal with JICA support for the rehabilitation of Units 4 and 5 at the Kaptai-based power station.
According to plant officials, the two 50 MW units are currently generating only around 40 MW each because of mechanical deterioration and structural weaknesses, reducing the plant’s overall output by nearly 20 MW.
The units have exceeded their scheduled overhaul periods. Unit 4 was last renovated in 2010, while Unit 5 underwent overhaul in 2011.
Engineers said cracks in generator support structures and other mechanical faults have forced operators to carry out regular inspections, welding, and temporary maintenance to keep the units operational.
A technical inspection conducted by Japanese company Toshiba in early 2024 reportedly warned that continued operation without major overhaul could pose significant operational risks.
