All five units of the Karnaphuli Hydroelectric Power Station in Kaptai have resumed operation following a rise in the water level of the Kaptai Lake due to several days of heavy rainfall.
The five units have been operating simultaneously since 6:00pm on Tuesday, producing a total of 144 megawatts (MW) of electricity.
Confirming the development, plant Manager Engineer Mahmood Hasan said continuous rainfall and increased rush from upstream significantly raised the water level of the Kaptai Lake, enabling the authorities to operate all five units.
Of the total output, Units 1 and 2 are each generating 32 MW, Unit 3 is producing 30 MW, while Units 4 and 5 are each generating 25 MW, bringing total production to 144 MW.
The plant has an installed generation capacity of 230 MW.
Officials at the plant's control room said the water level in the Kaptai Lake stood at 79.86 feet mean sea level (MSL) as of 8:00pm on Tuesday, compared to the rule-curve level of 84.96 feet MSL for this time of the year.
Due to low water levels in recent months, the plant had been operating only one or two generating units at a time. Three units were brought into operation on Monday, four units on Tuesday morning before all five units became operational from Tuesday evening.
The maximum water retention level of the Kaptai Lake is 108 feet MSL, officials added.
