Continuous heavy rainfall has raised the water level of Kaptai Lake, enabling the Karnafuli Hydropower Plant in Rangamati to increase electricity generation. With improved water availability, all five units of the country’s only hydropower facility have been brought back into operation, producing a total of 150 megawatts of electricity as of Tuesday evening, July 7, 2026.

According to plant officials, the water level in Kaptai Lake has been rising steadily over the past several days due to persistent rain in Rangamati and surrounding areas. Previously, only two of the five units were operational because of low water levels. The resumption of all units marks a significant boost in generation capacity.

Officials noted that if rainfall continues and the lake’s water level increases further, there will be potential to expand electricity production beyond the current output. The Karnafuli Hydropower Plant has a maximum generation capacity of 230 megawatts.
