Shares
ISLAMAND - The second unit of the Tarbela 4th Extension Hydropower Project has resumed operation.
The first unit of the project had started power generation last week following the concerted efforts of WAPDA engineers for lifting of the draft tube gates, which were earlier stuck due to piling of silt because of unprecedented slide of water levels to the dead level and technical issues with valves on the penstock.
The first unit was generating power to its maximum capacity of 470 MW. Thus, both the units of project have now been providing a total of 770 MW electricity to the system.
Third unit of the project is also complete and expected to start power generation by end of this month.
Tarbela 4th Extension Hydropower Project has been constructed on Tunnel No. 4 of Tarbela Dam. The project has three generating units – 470 MW each – with total installed capacity of 1410 MW.
