Bangladesh’s sole hydroelectric power station, the Karnaphuli Hydropower Station, is facing a significant drop in power generation capacity due to overdue maintenance. The plant, built in 1962, has a total capacity of 242 MW, but currently only operates at 171 MW, a decrease of 30%.
The issue stems from the neglected maintenance of three out of the five turbines at the facility. Units 3, 4, and 5 haven’t been overhauled since 2012, 2010, and 2011 respectively, exceeding their recommended 10-year lifespan. This has led to problems like cracks in generator infrastructure and aging equipment.
While Units 1 and 2 received recent maintenance in 2021 and 2022, the remaining units require urgent attention. The Bangladesh Power Development Board (BPDB) has attempted to address the issue through tenders, but complexities related to bidding processes have resulted in cancellations.
There’s a glimmer of hope for Unit 3, where using spare parts might extend its operation for a short while. However, a full overhaul remains inevitable. Units 4 and 5 require a more extensive assessment. A recent inspection by Toshiba, the original manufacturer, revealed Unit 5 might be inoperable. A detailed report is expected soon.
The delay in maintenance comes at a cost. The BPDB warns that global price hikes due to the war in Ukraine could inflate repair costs by 25%. This could significantly impact the initially estimated cost of Tk 100 crore for overhauling Units 3 and 4.
Despite the challenges, efforts are underway to address the situation. The BPDB has instructed the plant manager to expedite the renovation process, and action will be taken once necessary procedures are completed.
