Old Jabban Power Station

Since its commissioning in 1937 with an initial installed capacity of 9.6 MW (3 units of 3.2 MW each), and addition of 10 MW (2 units of 5.0 MW each), Jabban Hydro Electric Power Station generated 5783.314 Gwh of cheap electricity till the last day of its operation on 12 November 2011.

Fire incident

The 70-year-old power house was badly damaged due to a fire incident on 11 December 2006. The extent of damage was such that it was not possible to restore operation of the existing units. Moreover, the plant equipment had already outlived its life. The situation necessitated to carry out rehabilitation of Jabban Hydroelectric Power Station on "fast track basis" by installing new machines of higher efficiency at the same site. The rehabilitation of the hydropower station was completed in 2013 with a total cost of Rs3.8 billion by the contractor HRL-CCPG JV (Habib Rafique Ltd. (Pakistan) & Central China Power Group China).
